11364416
The present disclosure relates generally to an exercising device; and more specifically, to a device and a method of foot exercise. More specific the device and method concern controlling and/or monitoring of the foot exercise. The device and method according to the present invention can be used to advantage in both training and therapy.
A variety of foot deformities and symptoms (such as wrong positioning of bones, muscles and so forth) may exist in a foot of a person. Such foot deformities may be congenital or acquired, or both congenital and acquired. In an example, commonly known foot deformities include Achilles tendonitis, Flatfeet, Metatarsalgia, second metatarsal overload syndrome, Neuromas, Stiff big toe joint, Bunions, Limited big toe motion, Hammertoes, Heel pain, Posterior tibial tendon dysfunction (PTTD), Nerve compressions within the foot/ankle/neuropathy/neuroma,Anterior compartment syndrome, Patello-femoral pain syndrome, Plantar fasciitis, Tarsal tunnel syndrome, Hallux limitus, Hallux rigidus, Hallux valgus, and so forth. The deformities and the symptons above can be caused by weaknesses in the foot and in the calf muscle.
Presently, known techniques for treatment of the foot deformities include surgical procedures. The known surgical procedures include removal of abnormal bones, removal of bone enlargements, realignment of bones, realignment of cartilagenous surfaces of toe joints and so forth. However, the known surgical procedures give rise to long periods of recovery and a need for patients to wear a cast or surgical boot for weeks following the surgical procedures. Furthermore, the patients are often left with significant scars and poor cosmesis. Finally, the surgical procedures are costly, have a lengthy operating time, and require extensive pre/post-operative care from trained medical staff.
Alternatively, the treatment of the foot deformities may include physical medicine and rehabilitation treatments. Typically, such treatments include use of bunion pads, external splints, and use of exercising devices. However, the physical medicine and rehabilitation treatments are associated with various drawbacks. For example, known foot exercising devices may be designed specifically to target particular joints or muscles of the foot. Moreover, the foot exercising devices may be side specific, i.e. could be used either for a given left foot or for a given right foot.
Therefore, in light of aforementioned problems associated with known approaches for providing treatment for foot deformities, there exists a need to address, for example to overcome, the aforementioned drawbacks associated with the treatment of foot deformities. The problems mentioned above can be solved by a foot exercising device described in PCT/SE2016/050973.

Although some modes of carrying out the present disclosure have been disclosed, those skilled in the art would recognize that other embodiments for carrying out or practicing the present disclosure are also possible.
The foot exercising device described in PCT/SE2016/050973 comprises a foot support. The foot support comprises an elevated footrest to support a foot of a person thereon. In an embodiment, the foot support may further comprise a platform, for example an extended platform having an extensive floor-contact area, coupled to the elevated footrest for supporting the elevated footrest on a floor.
The elevated footrest forms a positive elevation between a heel and toes of the foot. In an embodiment, the elevated footrest may be a raised and inclined surface to support the foot of the person thereon. Specifically, the elevated foot rest may be a wedge-like structure that is operable to form the positive elevation between the heel and toes of the foot. More specifically, the positive elevation refers to positioning of the toes at a higher level with respect to the heel of the foot on the elevated footrest. It may be evident that dimensions, namely a physical size, of the elevated footrest are suitable to accommodate the foot of the person thereon. In an embodiment, the elevated footrest may be operable to decrease an angle between a leg and foot of the person.
Optionally, the foot support may further comprise the platform, namely the extended platform, coupled to the elevated footrest for supporting the elevated footrest on the floor. Specifically, the extended platform may have a flat, wing-like structure suitable to be placed on the floor. In an embodiment the extended platform may be operable to receive a non-exercising foot of the person thereon. In another embodiment, for a person with stiff legs, the extended platform may be vertically adjustable or may be raised by a separate block on the floor.
The foot exercising device further comprises a lift wedge to be arranged on the elevated footrest. The lift wedge is operable to receive the toes thereon to form a positive elevation between middle foot bones and the toes of the foot. In an embodiment, the lift wedge may be loosely placed and coupled to the detachable angled plate. Specifically, the lift wedge is slidably placed on the detachable angled plate operable to increase an angle between the toe and the elevated footrest.
In one embodiment, the at least one sloped surface of the lift wedge may be made of a soft material. Specifically, the soft material may provide support and/or cushioning to the foot of the person. In an example, the soft material to make the at least one sloped surface of the lift wedge may be fabricated from a flexible polymeric material (for example a polymeric foam or flexible silicone structure), an inflatable weight-bearing arrangement (such an air-pillow arrangement), an assembly of weight-bearing elements that are operable mutually to reconfigure their relative spatial positions for providing support (such as a “bean-bag” type support), a liquid-filled or gel-filled cavity having flexible walls, and so forth. Specifically, the at least one sloped surface of the lift wedge may be coated with cellular rubber (such as neoprene). In an embodiment, the lift wedge may be vertically adjustable. Specifically, the lift wedge may be adjusted vertically to form different positive elevations between middle foot bones and the toes of the foot, according to requirements of the person.
In an embodiment, the lift wedge may be rotatable in operation, and may be coupled to the elevated footrest in operation. Specifically, the lift wedge may be rotated in operation to change a position thereof on the elevated footrest. It may be evident that the rotation of the lift wedge allows treatment of both feet of the person. In an example, a person with foot deformities in both feet may rotate the lift wedge to perform foot correction exercises for each foot.
In an embodiment, the lift wedge comprises at least one sloped surface. The at least one sloped surface is operable to receive the toes of the foot thereon to form a positive elevation between middle foot bones and the toes of foot. Specifically, the positive elevation refers to positioning of the toes at a higher level with respect to the middle foot bone on the elevated foot rest, using the lift wedge.
In an example, the lift wedge has one sloped surface. The lift wedge may be placed under the foot and the toes in a specific manner so that the lift wedge provides a stretching effect to joints between the toes and the middle foot bones by forming the positive elevation thereon. Specifically, the lift wedge may be located between the distal interphalangeal joint of each toe, the proximal interphalangeal joint of each toe, the metatarsophalangeal joint and the metatarsal head of each toe of the foot of the person. The lift wedge placed in aforementioned position may exert pressure on the metatarsophalangeal joint and head forming the positive elevation and stretching of muscles connected thereto. In such example, the lift wedge may be aligned with a line through the third joint of the toes. A deviation of up to +/−20 degrees from said line through third joint of the toes is acceptable.
In another example, the lift wedge has two sloped surfaces. Specifically, the lift wedge with two sloped surfaces may be used to treat both, a left foot and a right foot of the person without turning the lift wedge. It may be evident that the lift wedge is operable to receive only one foot at a time.
In another example, the lift wedge is placed under at least one toe of the foot. The lift wedge may be operable to increase the angle between the at least one toe and the elevated footrest to maximum mobility of the at least one toe of the person. For example, the maximum mobility of the at least one toe may be up to 90 degrees.
Furthermore, the foot exercising device comprises a tilting arrangement comprising a pair of spaced apart fixed plates coupled to the elevated footrest, at least one movable plate hingedly coupled to the fixed plates, a centre plate coupled with the at least one movable plate and a rod pivotally coupled to the centre plate.
It may be evident that the pair of spaced apart fixed plates supports the at least one movable plate. Furthermore, the at least one movable plate supports the centre plate. In an embodiment, the tilting arrangement may comprise a pair of spaced apart movable plates hingedly coupled to the fixed plates.
The centre plate is operable to receive a calf of the person. In an embodiment, the centre plate may comprise a cushion to support the calf of the person.
Optionally the rod is tiltable sideways to optionally the left and to the right to enable the rod to pass the back of the person when tilting the centre plate.
The rod of the tilting arrangement is operable to tilt the centre plate to exert pressure on at least the heel, the middle foot bones and the toes to perform foot correction exercises. Specifically, the rod may be moved in a manner such that the angle between a leg (or calf) of the person supported by the centre plate, and the foot placed on the elevated footrest, is decreased.
In an embodiment, the foot exercising device may comprise a detachable angled plate operable to be arranged between the lift wedge and the elevated footrest to form a positive elevation between a medial arch and a lateral arch of the foot of the person. Specifically, the detachable angled plate has a wedge like structure of dimensions suitable to fully receive the foot of the person thereon. More specifically, the positive elevation refers to positioning of the medial arch at a higher position with respect to the lateral arch on the detachable angled plate. In an embodiment, the detachable angled plate may form the positive elevation in a range of 4 degrees to 25 degrees. In an example, the detachable angled plate may have triangular cross section.
In an embodiment, the detachable angled plate may be turnable. In an example, the detachable angled plate may be turned through an angle in a range of 140 to 240 degrees, for example substantially 180 degrees, to accommodate the foot of the person thereon. For example, the detachable angled plate may be a pronation plate or a supination plate.
In an embodiment, the detachable angled plate is placed under the foot in a manner such that the detachable angled plate may exert pressure on a lower leg, the heel, the middle foot bones of the foot and muscle groups connected thereto. Specifically, the pressure may be exerted by forming the positive elevation between a medial arch and a lateral arch of the foot of the person.
In an embodiment, the foot exercising device may comprise a see-saw plate and a ridge member arranged on the elevated footrest. The ridge member is coupled to a central portion of the see-saw plate allowing the see-saw plate to tilt about the ridge member to form the positive elevation between a medial arch and a lateral arch of the foot of the person. Specifically, the see-saw plate may be used to treat both, a left foot and a right foot of the person without turning the lift wedge. It may be evident that the see-saw plate is operable to receive only one foot at a time.
In operation, the foot exercising device of the present disclosure may be used for exercising the foot of the person. The foot of the person may be placed on the elevated footrest to form the positive elevation between the heel and the toes of the foot. Thereafter, the lift wedge may be arranged between the elevated footrest and the at least one toe of the foot for forming the positive elevation between the at least one middle foot bone and the corresponding toe of the foot. In an embodiment, the detachable angled plate may be arranged between the lift wedge and the elevated footrest to form the positive elevation between the medial arch and the lateral arch of the foot of the person. In another embodiment, the see-saw plate may be arranged between the lift wedge and the elevated footrest for forming the positive elevation between the medial arch and the lateral arch of the foot of the person. The calf of the person may be supported against the centre plate of the tilting mechanism, and the rod may be manoeuvred to exert pressure on at least the heel, the middle foot bones and the toes to perform foot correction and strengthening exercises. In an embodiment, exercising the foot further comprises releasing pressure from at least the heel, the middle foot bones and the toes of the foot by moving away the rod.
In an embodiment, the exertion and release of pressure on at least the heel, the middle foot bones and the toes of the foot by moving the rod may be performed alternately for pre-determined time periods. In an example, the pre-determined time period may be in a range of 1 to 3 minutes each, for example 2 minutes each, for exerting and releasing pressure.
In an embodiment, the foot of the person may be placed on the elevated footrest in a specific manner such that the positive elevation is formed between the heel and the toes. Such positioning of the heel may provide a stretching effect to the heel, the lower leg, the middle foot bones, and muscles related thereto. Moreover, arranging the lift wedge between the toes and the elevated foot rest may provide a stretching effect to the middle foot bones, the toes and muscles related thereto. In an embodiment, arranging the detachable angled plate between the lift wedge and the elevated footrest may provide a stretching effect to the medial arch, the lateral arch, the middle foot bones and muscles related thereto.
In an embodiment, pressure on at least the heel, the lower leg, the calf, the middle foot bones, the toes, the medial arch, the lateral arch and the muscles related thereto, may be exerted by manoeuvring the rod of the tilting arrangement. In an example, the manoeuvring the rod may lead to exerting pressure on the lower leg by decreasing the angle between the leg (or calf) and the foot.
In an embodiment, the rod may be manoeuvred by the person for exerting the pressure on the lower leg. In another embodiment, the rod may be manoeuvred by a medical staff for exerting the pressure on the lower leg. In still another embodiment the tilting arrangement may be manoeuvred by a power device, e.g. an electric motor, controlled by a computer program according to a preset treatment model.
In an embodiment, pressure on the lower leg may be exerted by moving a knee of the person in a specific manner so that the angle between the leg (or calf) and the foot of the persona may be decreased.
In an embodiment, the non-exercising foot of the person may be operable to release pressure exerted to at least the heel, the lower leg, the calf, the middle foot bones, the toes, the medial arch, the lateral arch and the muscles related thereto. Specifically, the non-exercising foot may be moved to a forward position (or bent) for releasing the pressure exerted on the lower leg.
PCT/SE2016/050973 presents also a method for exercising a foot using the device. The foot exercising device is easy to install in limited space and is easy to operate. Furthermore, the device and method of, namely method for, exercising the foot provides a non-invasive solution for treatment of foot deformities, thereby reducing high costs associated with surgery and the need for extensive pre/post-operative care. Moreover, the described device and method and system may be used to treat both left foot and right foot of the person in a safe manner to minimise risk of injury to the person. Additionally, the device and method are designed to target desired joints and/or muscles of the foot, which allows a user to efficiently perform foot correction exercises.
When stretching the calf muscles, there are often no effect even if a great force is applied when dorsalflexing in the ankle. The reason is that there is a stress applied to the arch during the stretch. The calf muscles react negatively on that and get tensed as a protection.
To get effect of the stretching you have to stabilize the lateral arch. It has to be protected from the natural stress impact when you attempt to bend to the maximum in the ankle.
This is done through stabilization of the lateral arch of the foot.
By placing a wedge, which lifts the lateral toes Metatarsal 4-5, there will be a tension in the plantar fascia and the structures attached between the toes and the heel bone (calcaneus). A tension of these structures get the bones/joints in the foot “linked” together to form a stable unit.
When stretching in this position there will be a stability in the foot that allow the calf and foot muscles to relax, wherein the muscles can relax during the exercise.
When dorsal flexing the foot, the peroneus longus tendon will, when passing over the cuboid in the peroneal groove, enhance the locking effect of the cuboid into its locking position.
In one aspect, an embodiment of the present invention comprising sensors to measure the pressure applied to the calf and/or the sole of a person using the foot exercising device.
In another aspect, an embodiment of the present disclosure provides a method to measure the pressure applied to the calf and/or the sole of a person using the foot exercising device.
It has been shown that the level of the exerted pressure and a time the pressure is exerted on the calf and the sole affect the result of the treatment and the possibility to remove the symptom or deformities in the foot of a person. Also the correlation between the pressure on the calf and the sole may be important to get a positive effect of the treatment. Therefore, storing of the pressure measurements from patients can be used to create different models of optimal pressure and optimal treatment periods. For example may the pressure be applied with pressure release in between the pressure intervals. It is obvious that exerting and releasing of pressure can be accomplished manually by an operator or automatically by a power device without diverting from the intention of the present invention. In an automatic mode for example, different treatment models can be stored in a computer. A treatment model program can be chosen according to a person's foot problem and started by the operator to control and monitor the treatment regarding treatment time and pressure levels by means of the power device.

The steps 802 to 812 are only illustrative and other alternatives can also be provided where one or more steps are added, one or more steps are removed, or one or more steps are provided in a different sequence without departing from the scope of the claims herein. For example, the method 800 may comprise releasing pressure from at least the heel, the middle foot bones and the toes of the foot by moving away the rod.
According to the described method a person to exercise or to be treated could be in a sitting or in a standing position, wherein the exercise or the treatment of the foot can be performed with the knee in a bent and in an extended position.
When the person is in a sitting position with the knee bent the pressure on the sole of the foot are resisted by a counter hold above the knee. In a sitting position with the knees extended the pressure on the sole of the foot is resisted by the lower back and the pelvis.
