This invention is directed to; inter alia, methods for treating spinal disorders in a subject.
The spinal cord is a long, thin, tubular bundle of nervous tissue and support cells that extends from the brain (the medulla specifically). The brain and spinal cord together make up the central nervous system. The spinal cord extends down to the space between the first and second lumbar vertebrae; it does not extend the entire length of the vertebral column.
The spinal cord functions primarily in the transmission of neural signals between the brain and the rest of the body but also contains neural circuits that can independently control numerous reflexes and central pattern generators. The spinal cord has three major functions: A. Serve as a conduit for motor information, which travels down the spinal cord. B. Serve as a conduit for sensory information, which travels up the spinal cord. C. Serve as a center for coordinating certain reflexes.
Spinal cord pathologies can result from diverse pathologic processes including trauma. Irrespective of the pathogenesis, it can lead to significant impairment of motor, sensory, or autonomic function.
Spinal cord injuries can be caused by trauma to the spinal column, (stretching, bruising, applying pressure, severing, laceration, etc.). The vertebral bones or intervertebral disks can shatter, causing the spinal cord to be punctured by a sharp fragment of bone. Usually, victims of spinal cord injuries will suffer loss of feeling in certain parts of their body. In milder cases, a victim might only suffer loss of hand or foot function. More severe injuries may result in paraplegia, tetraplegia, or full body paralysis below the site of injury to the spinal cord.
Damage to upper motor neuron axons in the spinal cord results in a characteristic pattern of ipsilateral deficits. These include hyperreflexia, hypertonia and muscle weakness.
Lower motor neuronal damage results in its own characteristic pattern of deficits. Rather than an entire side of deficits, there is a pattern relating to the myotome affected by the damage. Additionally, lower motor neurons are characterized by muscle weakness, hypotonia, hyporeflexia and muscle atrophy.
Spinal shock and neurogenic shock can occur from a spinal injury. Spinal shock is usually temporary, lasting only for 24-48 hours, and is a temporary absence of sensory and motor functions. Neurogenic shock lasts for weeks and can lead to a loss of muscle tone due to disuse of the muscles below the injured site.

Additional objects, advantages, and novel features of the present invention will become apparent to one ordinarily skilled in the art upon examination of the following examples, which are not intended to be limiting. Additionally, each of the various embodiments and aspects of the present invention as delineated hereinabove and as claimed in the claims section below finds experimental support in the following examples.
In all case studies, pain is presented as graded by the patient on a 10 cm Visual analogue scale (VAS). The ends of the scale were defined as 0—no pain and 10—worst pain imaginable. A pain of 4/10 means 4 cm out of 10 cm.
After each change (calibration, positioning) in the configuration of the protuberances attached to the footwear, the patient was asked to walk a distance of 20 meters in order to verify that the patient remains balanced and that the change in configuration resulted in a desired effect.
The device comprises 2 units of footwear: one for the left foot and one to the right foot. The footwear used is a light walking boot.
Prescription includes a set of instructions to the patients. These instructions included: duration of wearing the device per day (usually 30-60 minutes daily). Daily use included wearing the device during routine activities that may include watching TV, computer activities; eating activities, etc. Actual walking constituted 10-25% of 30-60 minutes. Thus, if patient wore the device for 60 minutes per day, total of 5-10 minutes were dedicated, accumulatively, to walking.
Gait measurements include spatio-temporal measurements performed by various computerized mats as well as three-dimensional gait labs or other gait lab that are able to measure velocity, step length and single limb support. Unless noted otherwise, the gait lab is done when patient is barefoot.
In the studies below, physiological values of Single Limb Support are between 38%-40% of the step cycle. In some pathologies (e.g. reduced sensory input, central or neurological pain, and the like), the single limb support is usually lower than 40% and sometimes lower than 38%. In other pathologies (e.g. hyper-mobility of the joints and/or poor proximal (pelvic) control) single limb support is usually higher than 40%.
In the “pain” section of the calibrations a repeated shift is described in order to bring the patient to a reduced pain calibration. In some cases, a shift of a protuberance(s) of 2 mm is repeated between 1-3 times until reaching the desired effect. In some cases, the process can include shifting more than 3 times of over 2 mm, to eventually 1 cm or more from the “Balanced” position, until the desired effect is achieved. As long as the shift does not result in excessive eversion or inversion.
A 52 years old man was presented to the treatment center with a diagnosis of central spinal stenosis.
Case History:
2 years ago the patient was involved in a working accident in which he fell backwards on his back from the scaffolding in a construction site. He was rushed to the hospital complaining of severe low back pain. A computerized tomography scan (CT scan) revealed that the L3-L4 disc was protruded and causing a mild to moderate narrowing of the central spinal canal. The patient refused surgery and was released after being hospitalized for three days for observation. Since then his condition worsened and he started suffering from symptoms referred to both legs. He reported having pain and a sensation of heaviness in both calves during walking (for over 20 minutes) and standing (for over 10 minutes). These symptoms were relieved only if he sat down. He also reported having night cramps in both calves and feet which woke him every night.
Physical Examination:
On observation the patient has hypolordosis and stands in slight forward trunk lean. Leg alignment (hips, knees, ankles and feet) is normal. Functional tests—the patient performs a full squat without difficulty or symptoms and is able to walk on his tip toes and on his heels without difficulty (These tests are used as a functional muscle strength assessment in order to ascertain any neurological weakness to major muscle groups). Clinical gait assessment shows the patient walks with small steps and small amplitude of arm swing. Test for spinal stenosis (part 1) showed that the patient was able to walk for 7 minutes and 26 seconds before he started feeling mild pain in the right calve (this test will be repeated later with the device in order to assess the functional impact of the device on the patients symptoms). Back range of motion is full in forward flexion and left and right rotations. It is limited to 75% of normal range in both left and right side flexion and limited to 20% of normal range in extension. Sustained extension (spinal stenosis test) produces pain and paraesthesia in both calves after 30 seconds. A neurological assessment revealed reduces Achilles reflex bilaterally, mild hypoesthesia in the posterior aspect of both calves and plantar aspects of both feet (S1-S2 dermatomes). Straight leg raise (SLR) was bilaterally limited to 45 degrees due to pain in the posterior aspect of the thigh and calve. Manual muscle testing did not reveal any weakness.
Gaitlab and Imaging:
A magnetic resonance imaging (MRI) performed 4 months prior to the date of the consultation shows mild to moderate narrowing of the central spinal canal due to a protrusion of L3-L4 disc and a central disc bulge of the L4-L5 disc, without narrowing of the spinal canal. There were degenerative changes to the facet joints bilaterally at L3-L4, L4-L5 and L5-S1. Gait lab results showed a velocity of 78 cm/sec, single limb support of 39.7% in the right leg and 39.2% in the left leg. Left step length: 47.0 cm Right step length: 46.1 cm.
Bulbous Protuberances (BPs):
Identical BPs with B convexity and “soft” resilience were attached and fixed to the footwear under the hind foot and fore-foot of the left and right device. A 100 gr. weighted spacer (disc) of 2.5 mm height was attached and fixed between the device and the posterior BP under the left leg and the right legs. In order to maintain the anterior BPs at the same height so as not to create a plantar flexed position a hard spacer and a soft spacer was introduced and fixed between the anterior BP and shoe both under the left leg and the right leg.
Balancing Process:
The device was calibrated and fine tuned during repeated clinical gait assessments. During this process care was taken to reduce the eversion and inversion during heel strike, loading response, mid-stance and toe-off. In this particular case, the balanced position is medial to the longitudinal axis of the device (system)
Pain:
In order to reduce pain in the lumbar spine, the posterior B.P.'s were calibrated and fixed 15 mm more posterior and 4 mm medially to the balanced position. The patient was asked to walk 20 meters with the device and he then reported feeling no lumbar pain, and his gait was balanced. In order to reduce pain in the calves, two additional hard spacers were added and fixed under the anterior BPs of both the right and the left units. This brought both ankles to a dorsiflexed position. During the repeated gait assessment the patient reported feeling no pain or heavy sensation in the calves.
Heel-Rise Timing:
The patient was asked to walk 10 meters back and forth in order to confirm that the gait is balanced with regard to ankle inversion and/or eversion angles and that the heel-rises in an appropriate timing. It was noted that the patient had an early heel-rise in both the right and left legs. In order to correct the early heel rise one of the hard spacers in the anterior B.P.'s was changed to soft spacers, bringing both feet to a slightly less dorsiflexed position. The patient was observed walking with the device and the timing of the heel rise was noted to have been corrected in the left leg. At this point the test for spinal stenosis (part 2) was repeated and the patient was able to walk for 11 minutes before reporting pain in the right calve (an improvement to the 7 minutes and 26 seconds to the appearance of pain while walking barefoot, this indicates a potential for improvement with the device).
Treatment Plan:
As was described above the patient felt an immediate relief in pain when walking with the device during the initial consultation. The patient was now briefed with safety instructions and was asked to wear the device at home for 30 minutes a day on each day of the first week of the treatment. Out of this total wearing time he was instructed to spend an accumulative time of 5-8 (about 20% of total wearing time minutes) in weight bearing activities (walking or standing while performing daily routine—see item 3 in the clarification section). Patient was instructed to increase overall daily wearing time of the device by 10 minutes every week for the initial 3 weeks, reaching 60 minutes wearing time with the device every day, while maintaining the 20% accumulative weight bearing time (thus reaching an accumulative weight bearing time of approximately 10-15 minutes). The patient was seen for follow-up consultations at the treatment center 3 weeks after his first visit, 8 weeks after his first visit, and 5 months after his first visit. Each follow up consultation consisted of a Gaitlab test, an interview performed by the treating Therapist (including report of current symptom level rated on a VAS and report of difficulty in function), a clinical assessment of gait without and with the device and a treatment plan for the duration of time till the next follow up.
Treatment Progression:
In the first follow up consultation the patient reported that he found simple house chores (such as making a cup of coffee) much easier while wearing the device. A barefoot gait lab test (see table no. 1) showed an increase in gait velocity (88 cm/second) and increases in both left and right step lengths (51 cm. in both). The patient was then instructed to continue to increase the overall wearing time of the device by 10 minutes per week while maintaining an accumulative weight bearing time of 20%. In the second follow up consultation the patient reported he has reached an overall wearing time of 2 hours and 10 minutes per day. He reported that he had no difficulty in standing and cooking for as long as 30 minutes with the device and that his night cramps were significantly reduced. When inquired about outdoor activities he reported that he still found walking painful after about 30 minutes (a 10 minute improvement to the baseline). A barefoot gait lab test revealed that step lengths in both the right and the left legs and gait velocity have improved (see table no. 1 for details). A clinical gait assessment without the device showed improved arm swing.
In order to increase the level of perturbation, the anterior and posterior B.P.'s in both units of the device were changed to a C convexity with soft resilience. A clinical gait assessment showed that the heel rise timing was normal and the patient reported feeling comfortable while walking with the device. He was then instructed to maintain the 2 hour and 10 minutes of wearing time of the device for the next 2 weeks so that he has time to adjust to the new level of perturbation. If he continued to feel comfortable with the device he was told to add 5 minutes of outdoor walking with the device starting from the third week, in addition to the above period of indoor wearing time. He was instructed to increase the outdoor walking by 5 minutes per week up to a maximum of 30 minutes per week.
In the third follow up consultation the patient reported he had the device on for 3 hours a day out of which he walked outside for 30 minutes. He reported that he started feeling pain and heaviness in his feet (but not in his calves) after about 45 minutes of walking with regular shoes. A barefoot gait lab test showed that his gait velocity and step lengths were further improved (see Table no. 1, below). He was instructed to maintain this amount of wearing and no further changes were made in the calibration of the device. After the initial 5 months the patient continued to come for follow-up consultations 2-3 times a year.
A 40 years old woman was presented to the treatment center with a diagnosis of L5-S1 nerve root compression and right drop foot.
Case History:
the patient reports that she had bouts of low back pain with radiating symptoms to the right leg for 10 years. 4 months ago she started having severe pain in the lateral aspect of her right calve. The pain started insidiously but was accompanied by hypoesthesia. Within a week she started having difficulty in walking and was referred to the emergency room by her treating physician. She underwent laminectomy, disectomy and fusion of the L5-S1 level. The surgery relieved the pain and hypoesthesia significantly, but the difficulty on walking remained. She currently reports she finds walking on uneven ground difficult due to poor clearance of her right foot. She still suffers from constant pain in the L5 dermatome (VAS 3/10). She also has pain in the lumbar area during prolonged standing (25 minutes, VAS 4/10) and prolonged sitting (1 hour, VAS 2/10). Both these pains are relieved by movement, such as walking.
Physical Examination:
On observation the patient has hyperlordosis. Knee alignment was in mild valgus and an apparent atrophy of the gastro-soleus complex of the right leg was observed. Functional tests—the patient performed a full squat without difficulty or symptoms. When weight bearing on the right leg during walking on tip toes the right foot drops about 4 cm. but does not reach the ground. Clinical gait assessment shows the patient uses high stepping gait during right swing. Back range of motion was full in forward flexion and rotation. Side flexion (left and right) was limited to 80% of normal range without symptoms. Extension caused the pain in the right calve to increase at 80% of normal range. A neurological assessment showed hypoesthesia in the right L5 dermatome and a reduced right Achilles reflex. Manual muscle testing revealed that the right extensor digitorum longus, extensor hallucis longus and tibialis anterior were all weak and rated at −4/5. SLR was limited on the right to 50 degrees while the left was normal (75 degrees).
Imaging and Gait Lab:
The patient had imaging (MRI) performed prior to surgery and this showed a protruded L5-S1 disc compressing the L5 right nerve root. Gait lab results revealed slow gait velocity 102 cm/sec, left step length: 53 cm. right step length: 57 cm. left single limb support 41.8 and right single limb support 35.7 (see Table 2 for gait lab results).
Bulbous Protuberances (BPs):
Identical BPs with B convexity and “soft” resilience were attached and fixed to the footwear under the hind foot and fore-foot of the left and right device. A 100 gr. weighted spacer (disc) of 2.5 mm height was attached and fixed between the device and the anterior BP under the left leg and the right legs. This was done in order to functionally strengthen the dorsiflexors during swing.
Balancing Process:
The patient's device was calibrated and fine tuned during repeated clinical gait assessments. During this process care was taken to reduce the eversion and inversion during heel strike, loading response, mid-stance and toe-off.
Pain:
In order to maintain the ankles at a dorsiflexed position, which is assumed to bring the lumbar spine to a more flexed position (lumbar extension elicited pain during physical assessment), no spacers were added to the posterior B.P.'s in either the right or the left units of the device. A dorsiflexed position also allows better clearance during swing. The patient was asked to walk 20 meters with the device again and she reported feeling back pain (VAS 1/10) and right calve pain (3/10). Clinical assessment of her gait showed that her clearance was improved and the high stepping gait was reduced. In order to reduce pain in the lumbar spine the posterior B.P.'s were calibrated and fixed 10 mm more posterior and 4 mm medially to the balanced position. The patient then reported feeling no lumbar pain while walking with the device and her gait was balanced, the leg pain persisted at a level of 2/10. In order to reduce her leg pain one hard spacer was inserted and fixed under the anterior and posterior B.P.'s of the right unit. This calibration, called “off-loading”, is supposed to make swing of the contra-lateral leg easier by increasing the height of the device in the involved leg. In this case the difficulty in left swing is demonstrated by the gait lab results: shorter step length of the left leg and the low single limb support on the right. The patient was asked to walk 20 meters and she reported that the pain in the right leg was now at a level of discomfort and not pain.
Heel-Rise Timing:
The patient was asked to walk 10 meters back and forth in order to confirm that the gait is balanced with regard to ankle inversion and/or eversion angles and that the heel-rises in an appropriate timing. No apparent gait deviations were observed.
Gaitlab Retest:
Once the balancing process was completed the patient performed another gaitlab test with the device. The results of this test were significantly better than the baseline results. Gait velocity increased to 118 cm/sec., left single limb support: 38.5%, right single limb support 37.3%, left step length 58 cm. and right step length was 60 cm. (see Table 2). It is believed that as the treatment progresses and the patient wears the device for longer periods of time
Treatment Plan:
As was described above the patient felt a significant relief in pain when walking with the device during the initial consultation. The patient was now briefed with safety instructions and was asked to wear the device at home for 30 minutes a day on each day of the first week of the treatment. Out of this total wearing time she was instructed to spend an accumulative time of 5-8 (about 20% of total wearing time minutes) in weight bearing activities (walking or standing) while performing daily routine. She was instructed to increase overall daily wearing time of the device by 15 minutes every week for the initial 3 weeks, reaching 75 minutes of wearing time with the device every day, while maintaining the 20% accumulative weight bearing time (thus reaching an accumulative weight bearing time of approximately 15-18 minutes). The patient was seen for follow-up consultations at the treatment center 3 weeks after her first visit, 6 weeks after her first visit, 3 months after her first visit and 6 months after the first consultation. Each follow up consultation consisted of a Gaitlab test, an interview performed by the treating Therapist (including report of current symptom level rated on a VAS and report of difficulty in function), a clinical assessment of gait without and with the device and a treatment plan for the duration of time till the next follow up.
Treatment Progression:
In the first follow up consultation the patient reported that while she did feel less pain with the device she did not notice any improvement without it. Her barefoot gait lab results showed some improvement indicated by better symmetry in step length (left 54 cm. right 57 cm.) and single limb support (left 41.2 right 36.3) along with a mild increase in gait velocity (108 cm/sec) (see table 2 for results). She was instructed to keep increasing the wearing time of the device by 15 minutes per week, reaching 2 hours by the next follow up consultation. She was instructed to maintain 20% of accumulative weight bearing time.
In the next follow up consultation the patient reported that she wears the device for 2 hours each day. She felt an improvement in her gait without the device and reported that she had less incidents of her right foot failing to clear the ground during swing. Her pain was also reduced to a level of 1-2/10 in the right leg and in her lower back. The gait lab results showed further improvement in comparison to the first follow up consultation (see table no. 2). Gait velocity has improved to 118 cm/sec, left step length to 56 cm, right step length to 58 cm., left single limb support to 40.4% and right single limb support to 37.8%. Clinical gait assessment showed a reduction in high stepping gait and manual muscle testing showed muscle strength of the right extensor digitorum longus, extensor hallucis longus and tibialis anterior improved to −5/5. The hard spacers on the anterior and posterior B.P.'s of the right unit which were used for offloading were removed and the B.P.'s were fixed in the same position. The patient was asked to walk with the device and did not report any pain or symptoms. In order to increase the level of perturbation the posterior B convexity caps of the right and left units were changed to caps with a C level of convexity. Since the posterior B.P.'s with the C caps were now higher than the anterior B.P's with the B convexity caps, the dorsiflexion in the ankles was lost. In order to regain the dorsiflexion a soft and a hard spacer were inserted and fixed under the anterior B.P.'s of both the right and the left units. The patient was asked to walk with the device and reported she felt comfortable with it. Her gait was observed to be well balanced and heel rise timing appeared normal. The patient was instructed to maintain the 2 hours a day of wearing the device for the next two weeks in order to allow her to get used to the new device calibration. She was then instructed to begin walking outdoors with the device for 5 minutes per day in addition to the 2 hours indoors. Provided she felt comfortable walking outdoors (no fatigue or increased symptoms) she was instructed to increase the outdoor walking by 5 minutes every week, up to a maximum of 30 minutes. The patent was further instructed to continue wearing the device indoors for 2 hours a day.
In the third follow up consultation the patient reported she enjoyed walking outdoor with the device and could walk for 30 minutes without difficulty pain or symptoms. She also continued wearing the device at home for 2 hours each day. She reported that she no longer had any back or referred leg pain unless she over exerted herself (for example, cooking for a period exceeding 2 hours). Her barefoot gait lab results showed further improvement (see table no. 2 for details). A manual muscle testing of the relevant muscles did not show any weakness. Walking on tip toes showed only a minor drop of the right foot (0.5 cm. in comparison to 4 cm. during the initial physical examination). In order to increase the level of perturbation the anterior caps of the right and left B.P.'s were changed from a B convexity to a C convexity. In order to maintain the same degree of dorsiflexion the hard and soft spacers added to the anterior right and left B.P.'s in the previous follow up consultation were removed and the B.P.'s were fixed in the same position. The patient was asked to walk 20 meters with the device and her gait was well balanced. She reported feeling comfortable with the device and was instructed to maintain the same amount of usage of the device, both indoors and outdoors.
In the fourth follow up consultation the patient reported that she did not notice any further improvement in her condition. Barefoot gait lab results, manual muscle testing and clinical gait assessment revealed results similar to the previous follow up consultation. Since the last changes in the calibration of the device (in the third follow up consultation) did not cause any further improvement in the patient's condition, no further changes were made in the calibration. The patient was instructed to maintain the amount of wearing the device.
After the initial 6 months the patient continued to come for follow-up consultations 2-3 times a year.
A 55 years old woman was presented to the treatment center with a diagnosis of Non-Specific Low Back Pain (NSLBP).
Case History:
The patient reports that for the past 3 years she has suffered from pain in the lower back and right buttock area. The pain has started after a bout of strenuous activity (cooking and decorating) but she rules out any trauma. Over the time that has elapsed since the pain began she has tried physiotherapy, alternative medicine (Ayurveda) and swimming, none of which significantly relieved her pain. She reports that she is now limited in her daily activities due to pain. She is unable to stand for more than 25 minutes (VAS 5/10 in the lower back), getting up after prolonged sitting causes low back pain (VAS 6/10 which reduces to 2/10 after a minute of walking), as does bending down (VAS 6/10). She reports that when the pain in her back worsens she has pain in her right buttock and over the area of the lateral right thigh (non-dermatomal pain distribution). An MRI performed six months prior to the consultation has shown mild degeneration of the L3-L4-L5-S1 discs, without any herniation or pressure on neural structures.
Physical Examination:
On observation the patient is hyperlordotic, leg alignment (hips, knees, ankles and feet) is normal. Functional tests: the patient performs a full squat without difficulty or symptoms and is able to walk on his tip toes and on his heels without difficulty. Clinical gait assessment revealed reduced arm swing bilaterally and reduced pelvic rotation, both of which are considered indicative for bracing of the lumbar and thoracic musculature. Back range of motion was: lumbar extension 75% of normal ROM, right side flexion 50% of normal ROM (she reports pain and stiffness in the right lumbar area VAS 2/10), left side flexion 80% of normal ROM (she reports a stretching sensation on the right side of her lumbar region). Right and left rotations are within normal limits. When asked to perform lumbar flexion the patient was apprehensive, when she performed the movement she was able to complete 50% of normal range before complaining of right and left lumbar pain (VAS 6/10). A neurological assessment did not reveal any significant findings. SLR were 80 degrees bilaterally and did not produce any pain.
Gaitlab and Imaging:
An MRI performed six months prior to the consultation has shown mild degeneration of the L3-L4-L5-S1 discs, without any herniation or pressure on neural structures. Gaitlab results showed gait velocity of 68 cm/sec, left step length if 52.1 cm, right step length 51.5 cm., left single limb support was 40.2 in the left leg and 39.0 in the right.
Therapy:
Bulbous Protuberances (BPs):
Identical BPs with C convexity and “soft” resilience were attached and fixed to the footwear under the hind foot and fore-foot of the left and right units.
Balancing Process:
The patient's device was calibrated and fine tuned during repeated clinical gait assessments. During this process care was taken to reduce the eversion and inversion during heel strike, loading response, mid-stance and toe-off. In this particular case, as is common in most spinal cases, the balanced position is medial to the longitudinal axis of the device (device).
Pain:
The patient reported she still felt low back pain after the above calibration was performed (VAS 3/10). In order to reduce pain in the lumbar spine the posterior B.P.'s were calibrated and fixed 12 mm more posterior and 3 mm medially to the balanced position. The patient was asked to walk 20 meters with the device and she then reported feeling her lumbar pain was reduced (VAS 1.5/10). In order to reduce the pain further a hard spacer was inserted and fixed between the posterior right and left B.P.'s and the sole of the device. This brings the ankle to a plantar flexed position which is believed to bring the pelvis and lumbar spine to a more extended (anterior pelvic tilt) position. This was considered to be beneficial since the strongest pain was produced in lumbar flexion. The patient was asked to walk with this new calibration and reported her pain had decreased further to a level of a mere discomfort. Clinical gait assessment revealed that her gait was balanced.
Heel-Rise Timing:
The patient was asked to walk 10 meters back and forth in order to confirm that the gait is balanced with regard to ankle inversion and/or eversion angles and that the heel-rises in an appropriate timing. No visible gait deviations were seen.
Treatment Plan:
As described above, the patient felt pain immediate relief when walking with the device during the initial consultation and her gait was well balanced. The patient was now briefed with safety instructions. Since her step length's were decreased in comparison to the normal values (see table no. 3) her back musculature was considered too weak to cope with prolonged periods of wearing the device. She was therefore asked to wear the device at home for 20 minutes a day on each day of the first week of the treatment. Out of this total wearing time she was instructed to spend an accumulative time of 10%-15% (2-3 minutes) in weight bearing activities. Patient was instructed to increase overall daily wearing time of the device by 5 minutes every week for the initial 3 weeks, reaching 35 minutes wearing time with the device every day, while maintaining the 10-15% accumulative weight bearing time (thus reaching an accumulative weight bearing time of approximately 4-5 minutes). The patient was seen for follow-up consultations at the treatment center 3 weeks after her first visit, 6 weeks after her first visit, 14 weeks after her first visit and 6 months after the initial consultation. Each follow up consultation consisted of a Gaitlab test, an interview performed by the treating Therapist (including report of current symptom level rated on a VAS and report of difficulty in function), a clinical assessment of gait without and with the device and a treatment plan for the duration of time till the next follow up.
Treatment Progression:
In the first follow up consultation the patient reported that although she felt comfortable with the device on, she did not notice much of a change in her pain level or disability. A barefoot gait lab test (see table no. 3) showed an increase in gait velocity (88 cm/second) and increases in both left (52.1 cm.) and right (51.5 cm.) step lengths. In addition, the single limb support became more symmetrical (left 39.8, right 39.4) which is considered an improvement in motor control of gait. The patient was then instructed to continue to increase the overall wearing time of the device by 10 minutes per week while maintaining an accumulative weight bearing time of 10-15%. In the second follow up consultation the patient reported that she felt a decrease in pain during prolonged standing (VAS 2/10 after 45 minutes, an improvement in pain level and the amount of time she was able to stand). She has reached an overall time of an hour and ten minutes with the device, and felt she had very little pain when she had the device on. She reported that even standing after sitting was much less painful. Her gaitlab results showed further improvement in velocity and step lengths, the latter reaching normal values (see table 3). In order to increase the effect of the device the posterior B.P.'s of both the right and the left units were changed from a C convexity with a soft resilience to a D convexity with a soft resilience. The patient was asked to walk with the device and a late heel rise was observed bilaterally. This was attributed to the increase in the height of the posterior B.P.'s due to the increased convexity (the dorsiflexion was now lost since the D convexity is higher than the former C convexity). A hard spacer was inserted and fixed between the anterior B.P.'s and the sole of the left and right units. The patient was asked to walk again with the device and the late heel rise was observed to be corrected. She was then instructed to maintain the overall hour and ten minutes of wear time for the following two weeks in order to allow her to get used to the increased perturbation induced by the newly added D convexity. In the weeks following the first two the patient was instructed to increase the overall wearing time by 15 minutes per week, up to a maximum of three hours.
In the third follow up consultation (14 weeks after the initial consultation) the patient reported she occasionally felt pain in her lower back after standing for over three hours, the pain in the right buttock and the right thigh was completely alleviated. Her gaitlab results showed further improvement in velocity and left and right step lengths (128 cm/sec, 60.0 cm., 59.6 cm. Respectively, see table no. 3). During clinical gait assessment the arm swing and pelvis rotation was observed to be normal. This is considered an indication of a reduction of the bracing of spinal muscles, which is supported by the continuous improvement in gaitlab results. She was instructed to reduce the indoor overall wearing time to 2.5 hours and start performing outdoor walking for 10 minutes per day. She was asked to increase the outdoor walking by 5 minutes per week, to a maximum of 30 minutes.
In the fourth follow up consultation she reported having no problem with prolonged standing or sitting. She mentioned she felt free to bend down (lumbar flexion) and felt only a mild discomfort in her back while doing so. Nonetheless, she was urged to try to use a squat rather than lumbar flexion in order to bend forward. She was asked to maintain the 2.5 hours of indoor ADL and the 30 minutes of outdoor walking with the device. Following this, the patient was seen for follow up consultations every 4-6 months in order to continue to monitor her function and pain levels and regulate the treatment.
A 78 years old woman diagnosed with a fracture in the L1 vertebra, was presented to the treatment center.
Case History:
the patient had intermittent back pain more than 25 years. A year prior to her arrival, this pain was dramatically increased following an accident in which she fell from a chair on her buttocks. An X-ray micrograph revealed a partially collapsed compression fracture of the body of the L1 vertebra. Following the fracture she had bone density scan which revealed T −3.1 in L4-5 and T −2.3 in the femur's neck. She was prescribed alendronate (Fosalan) once a week. At the time, she reported that walking (15 minutes, VAS 4/10) and standing (5 minutes, VAS 5/10) aggravate her pain which is located in the low back. Bending forward (flexion) also increases her pain. To relieve the pain she had to lie down.
Physical Examination:
On observation the patient had a pelvic alignment of posterior pelvic tilt, hypo-lordosis and a as well as a hyper-kyphosis of the thoracic spine. Hip and knee alignment was normal. Lumbar movements reproduced her pain at 50% of the normal flexion range of motion and 80% of the normal extension range of motion. During clinical gait assessment decreased pelvic, lumbar and thoracic rotation which led to a reduction in arm swing was observed. The patient also reported of lumbar pain during the gait assessment which she rated verbally as 3/10. Neurological assessment of motor function and sensation in the lower limbs was normal.
Imaging and Gait Lab:
X-rays revealed a typical wedge shape of the vertebral body of L1. In addition a narrowing of the intervertebral disc space was observed in the L4-5 and L5-S1 segments, accompanied by degenerative changes of the facet joints in these segments. Gait lab results revealed slow gait velocity at 87 cm/sec, with short step lengths (left step length: 48 cm. right step length: 48 cm). Left single limb support was 38.7 and right single limb support was 39.1 (see Table 4 for gait lab results).
Bulbous Protuberances (BPs):
Identical BPs with B convexity and “soft” resilience were attached and fixed to the footwear under the hind foot and fore-foot of the left and right device.
Balancing Process:
The patient's device was calibrated and fine-tuned during repeated clinical gait assessments. During this process care was taken to reduce the eversion and inversion during heel strike, loading response, mid-stance and toe-off.
Pain:
In order to reduce the pain in the lumbar region, a hard spacer was attached and fixed between the device and the posterior BP under the left leg and the right legs. This created a slightly plantar flexed position of both ankles, inducing a more extended position of the lumbar spine. The patient was asked to walk 20 m with the device and she reported a reduction of back pain (VAS 1/10). In order to further reduce the pain, the posterior BPs were recalibrated to a more posterior position (2 mm posteriorly). The patient then reported of no lumbar pain while walking with the device and her gait was observed to be balanced.
Heel-Rise Timing:
The patient was asked to walk 10 m back and forth in order to confirm that the gait is balanced with regard to ankle inversion and/or eversion angles and that the heel-rises are in an appropriate timing. No apparent gait deviations were observed.
Treatment Plan:
Upon the completion of the calibration process the patient had a significant decrease in lumbar pain. The patient was then briefed with safety instructions and was asked to wear the device at home for 25 minutes for the first week of the treatment. Out of this total wearing time she was instructed to spend an accumulative time of 3-4 (about 15% of total wearing time minutes) in weight bearing activities (walking or standing) while performing daily routine. She was instructed to increase overall daily wearing time of the device by 10 minutes every week for the initial 3 weeks, reaching 55 minutes of wearing time with the device every day, while maintaining the 15% accumulative weight bearing time (thus reaching an accumulative weight bearing time of approximately 8-10 minutes). The patient was seen for follow-up consultations at the treatment center 3 weeks after her initial consultation, 9 weeks after her initial consultation and 4 months after her initial consultation. Each follow up consultation consisted of a gait lab test, an interview performed by the treating physiotherapist (including report of current symptom level rated on a VAS and report of difficulty in function), a clinical assessment of gait with and without the device and a treatment plan for the duration of time till the next follow up.
Treatment Progression:
In the first follow up consultation the patient reported of feeling comfortably with minor household chores while wearing the device. She also mentioned that her back feels slightly less stiff when she stands up after prolonged sitting. Her barefoot gait lab results showed some improvement and indicated a small increase in step length (left 49 cm. right 50 cm.) and velocity (95 cm/sec) (see table 4 for results). The patient was then observed walking without and with the device. Her gait in both cases was regarded as balanced and so no changes were made to the calibration of the BPs. She was instructed to keep increasing the total wearing time of the device by 15 minutes per week, reaching 145 minutes by the next follow up consultation. She was instructed to maintain 15% of accumulative weight bearing time.
In the second follow up consultation the patient reported that she is able to stand for an hour with a pain level of 1/10. Her walking, with her regular shoes, was also improved and she reported that now she is able to walk for half an hour with only some discomfort in her back. The patient reported that she wears the device for 2.5 hours each day and felt comfortable with it. The gait lab results showed further improvement in comparison to the first follow up consultation (see table no. 4). Gait velocity has improved to 105 cm/sec, left step length increased to 52 cm, right step length to 53 cm. Single limb support in both legs continued to be within the normal limits. Clinical gait assessment showed an increase in the rotation movement of the spine (pelvis, lumbar and thoracic) resulting in improved arm swing. Gait assessment with the device was balanced. In order to increase the challenge (induce muscle build-up) to the muscular system the caps of the posterior BPs were changed to a C level of convexity with soft resilience. Since the C caps are higher than the B caps, an increase in plantar flexion was introduced. In order to avoid this increase, the two hard spacers inserted between the posterior BPs and the device were removed from both right and left devices, and the BPs were fixed to their previous position. The patient was asked to walk with the device and did not report any pain or symptoms. Her gait was observed to be well balanced and heel rise timing appeared normal. The patient was instructed to decrease the overall wearing time of the device to 1.5 a day of wearing the device for the next two weeks in order to allow her to get used to the new device calibration. Following this period, she was asked to increase the wearing time by 20 minutes per week to a maximum wearing time of 4 hours.
In the third follow up consultation the patient reported she enjoyed wearing the device daily for 4 hours while performing household tasks. She also reported on her new ability of walking outdoors for an hour with regular shoes before the back pain appears. Her gait lab results showed further improvement (see table 4) with step length reaching 58 cm. and 59 cm. for the left and the right respectively. Velocity increased to 118 cm/sec and both velocity and step lengths were now within normal limits. The patient was then went through gait assessment while walking with and without the device and her gait was observed to be without any deviations. No further changes were made to the calibration of the device and the patient was asked to continue to wear the device daily for 4 hours.
After the third follow up consultation the patient continued to come for follow-up consultations 3 times a year in order to verify that she continued to feel well and that her calibration remained balanced.
A 13 years old girl diagnosed with idiopathic scoliosis was presented to the treatment center.
Case History:
the patient has been diagnosed with thoraco-lumbar scoliosis, 4 months prior to her arrival at the treatment center. She has not been suffering from any symptoms such as pain or discomfort in her back. She has been menstruating irregularly for the past 8 months. Her treating orthopedic surgeon has considered the use of a brace in order to prevent deterioration of the scoliosis. Both the patient and her parents were eager to avoid the use of a brace.
Physical Examination:
On observation the patient has no apparent pelvic obliquity. Her spine is hypo-lordotic and hypo-kyphotic with an apparent right main thoracic curve and a secondary left lumbar curve. Adam's test is positive with a hump apparent in the right rib cage. Ranges of motion of other spinal movements are within normal limits. Leg length measurements do not reveal any leg length discrepancy.
Imaging and Gait Lab:
X-rays revealed a right thoracic curve (Cobb angle of 33 degrees) with an accompanying right rotation of the vertebral bodies. The lumbar compensatory curve has a Cobb angle of 15 degrees. Risser sign was measured as Risser II. Gait lab results revealed normal velocity and step lengths (velocity 123 cm/sec, left step length: 57 cm. right step length: 57 cm.). Both the left and the right single limb supports were above the normal values (left 42.3, right 42.0) (see Table Y for gait lab results). The high single limb support values are considered a sign of poor muscular control around the pelvis during gait.
Bulbous Protuberances (BPs):
Identical BPs with C convexity and “hard” resilience were attached and fixed to the footwear under the hind foot and fore-foot of the left and right device.
Balancing Process:
The patient's device was calibrated and fine-tuned during repeated clinical gait assessments. During this process care was taken to reduce the eversion and inversion during heel strike, loading response, mid-stance and toe-off.
Alignment:
In order to improve the spine's alignment, the anterior and posterior BPs of the left device were recalibrated 3 mm to a more medial position. The patient was then asked to walk back and forth for 10 meters and her gait was observed to be balanced. She also reported she felt comfortable walking with the device. In order to support the hypo-lordosis of the lumbar spine the posterior BPs of both the left and the right devices were calibrated 4 mm anteriorly. The patient was asked to walk with the device again and her gait was again observed to be balanced. In order to improve the muscular control around the pelvis, two weighted spacers (disc), 3 mm high and 100 gr. in weight, were inserted and fixed between both the right and the left posterior BPs. In order to avoid a plantar flexed position of the ankles (caused by the insertion of the discs) one hard spacer and one soft spacer were inserted and fixed between both the right and the left anterior BPs. The patients gait was observed again and was considered balanced. An observation of her standing posture with the device showed a reduction of the lumbar and thoracic scoliotic curvatures. The patient reported that she felt comfortable walking and standing with the device.
Heel-Rise Timing:
The patient was asked to walk 10 meters back and forth in order to confirm that the gait is balanced with regard to ankle inversion and/or eversion angles and that the heel-rises in an appropriate timing. No apparent gait deviations were observed.
Treatment Plan:
The patient was asked to wear the device daily, indoors, for an hour. She was encouraged to be active while wearing the device performing such activities as walking about the house, doing her hair standing in front of the mirror etc. She was asked to increase the overall wearing time of the device by 20 minutes each week. The patient was seen for follow-up consultations at the treatment center 5 weeks after her initial consultation, 10 weeks after her initial consultation, 5 months after her initial consultation and 9 months into the treatment. Each follow up consultation consisted of a gait lab test, an interview and an observation of standing posture performed by the treating physiotherapist, a clinical assessment of gait without and with the device and a treatment plan for the duration of time till the next follow up. In addition any new X-rays were reviewed, measured and recorded.
Treatment Progression:
In the first follow up consultation the patient reported she has been wearing the device daily and has reached an overall wearing time of two hours and forty minutes. Her barefoot gait lab results showed a decrease in left and right single limb support (left 41.8, right 41.5) with a small increase in bilateral step length and velocity (see table Y for results). The patient has not been re-evaluated by X-ray but an observation of her posture during standing position revealed a small decrease in lumbar and thoracic scoliosis curvatures. The patient was then observed walking with and without the device. Her gait in both cases was regarded as balanced. In order to increase the neuro-muscular challenge introduced by the device and to enhance muscular training the caps of all BPs were changed from a “C” level of convexity to a “D” level of convexity with hard resilience. Her gait with the device was reassessed and was considered to be balanced. In order to allow her to get accustomed to the increased level of convexity (increased perturbation of the gait) she was instructed maintain the same amount of time and level of activity with the device for the next two weeks. Following these two weeks the patient was instructed to start walking outdoors with the device, starting with 15 minutes walk and increasing walking time by 5 minutes per week. She was asked to get to a maximum of 45 minutes. In addition to the outdoor walking she was asked to continue wearing the device in the house as well.
In the second follow up consultation, 10 weeks after the commencement of the treatment, the patient reported that she was doing three or four 50 minute walks with the device. In addition, she has been wearing the device in the house for 3-4 hours a day. New X-rays of her spine showed a decrease of the Cobb angle of the thoracic curvature from 33 degrees to 26 degrees. The lumbar Cobb angle decreased as well from 15 degrees to 12 degrees. The barefoot gait lab results did not show any significant changes from the previous follow up consultation (see table 5). Clinical gait assessment, both barefoot and with the device, showed a good gait pattern. The patient was encouraged to maintain the same treatment plan with the device, wearing it both outdoors and in the house as previously described.
In the third follow up consultation the patient reported she continued to wear the device according to prescribed treatment plan. She did not have any new X-rays so a careful observation of her standing posture was conducted. This revealed a further decrease of scoliotic posture as well as a decrease in thoracic vertebral rotation (assessed with the Adam's test). The patients gait was then observed and was considered well balanced. Her barefoot gait lab results showed maintained lower values of single limb support bilaterally, though these were still higher than normal values (see table 5). Due to the apparent improvements in scoliotic curvatures the anterior and posterior BPs of the left device were recalibrated and fixed 2 mm more laterally. The patients gait was observed and was considered well balanced. The patient also reported that she felt comfortable with the new calibration. She was then asked to continue wearing the device according to her current treatment plan.
In the fourth follow up consultation the patient had new X-rays with her who revealed a further decrease of the thoracic Cobb angle to 21 degrees and a 12 degree Cobb angle of the lumbar curvature. The patient reported she continued to use the device at least four times a week, doing both indoor and outdoor activities. Her gait lab results are shown in table 5. A clinical gait assessment showed that her gait was balanced and so no changes were made in the calibration of the device.
After the third follow up consultation the patient continued to come for follow-up consultations 3 times a year.
