Tendonitis is a prevalent condition amongst those leading an active lifestyle. Tendonitis is an inflammation or irritation of a tendon resulting in pain and tenderness just outside a joint, often induced by repetitive forceful motion. Tendonitis can occur in any tendon, but is most commonly experienced around the shoulders, elbows, wrists, knees and heels. Some common names for tendonitis include tennis elbow, golfer's elbow, pitcher's shoulder, swimmer's shoulder and jumper's knee.
A common form or tendonitis is Achilles tendonitis, which is sometimes associated with Plantar fasciitis (which involves inflammation of a thick band of tissue that runs across the bottom of the foot). Plantar fasciitis isn't technically a form of tendonitis because the plantar fascia isn't a tendon, but the conditions and treatments can be very similar.
Additionally, if tendonitis persists for several months, a condition known as tendinosis can develop. This type of condition can involve degenerative changes in the tendon along with abnormal blood vessel growth
Most cases of tendonitis can be successfully treated with rest, physical therapy and medications to reduce pain. A common physical therapy treatment for tendonitis involves periodic instrument assisted mechanical scraping or rubbing of the affected area by a trained professional over several weeks or months. This technique is generally known as Instrument Assisted Soft Tissue Mobilization (IAS™). Two well-known IAS™ therapeutic methods are the Graston™ Technique and Gua sha.
Unfortunately, the time commitment and expense involved in completing the therapy often causes persons afflicted with tendonitis to prematurely discontinue the therapy as soon as the pain begins to subside, resulting in an increased risk of reinjury.
Accordingly, a need exists for a safe, affordable and easy-to-use mechanical muscle and tendon scraping or rubbing instrument which persons afflicted with tendonitis or a similar condition that responds favorably to mechanical muscle and tendon scraping or rubbing can use at home.
A therapeutic apparatus and a method for providing parallel mobilization treatment of a muscle or a tendon in a limb utilizing the therapeutic apparatus.
The therapeutic apparatus includes a driven endless belt, a plurality of contact elements, and a housing. The driven endless belt has a machine direction, a cross direction and a transverse direction for movement along a path which includes an interaction segment. The contact elements are attached to, project transversely from, and are spaced along the machine direction of the endless belt. The housing encloses the endless belt with a machine direction slot through the housing through which the contact elements project as they travel along the interaction segment of the path.
The treatment method includes the steps of (i) identifying a tender location on a limb in need of parallel mobilization treatment, (ii) obtaining a therapeutic apparatus having a plurality of contact elements which travel in a first machine direction along a path which includes an interaction segment, (iii) releasably securing the therapeutic apparatus to the limb whereby the interaction segment overlays the tender location, and (iv) activating the therapeutic apparatus to drive the contact elements along the path in the first machine direction for a defined therapeutic duration during which the elements contact and effect parallel mobilization of a muscle or a tendon at the tender location.

A single wheel (not shown) could be employed as an alternative to the endless belt 110, but is not preferred as the contact elements 130 would travel along an arc rather than a straight line through the interaction segment 129s of the path 129.
The motor 140 drives the endless belt 110 in the first machine direction 110m1 along the path 129 at a defined speed. A suitable range for speed of travel is between 1 and 10 ft/min. A speed of travel slower than about 1 ft/min unnecessarily prolongs each treatment while a speed of travel faster than about 10 ft/min can irritate the skin and reduce effectiveness of the treatment as it diminishes the time period between scrapings during which the muscle or tendon recovers from the previous scrape.

The contact elements 130 can be releasably attached to the endless belt 110 for allowing replacement of worn or damaged contact elements 130 and replacement of the contact elements 130 with ones of different size, shape, hardness, etc.

A slot 309 extending in the machine direction 110m from the front 300a to the back 300b of the housing 300 extends through the bottom 300f of the housing 300. The slot 309 is positioned and sized for allowing the contact elements 130 to project out from the interior of the housing 300 and unidirectionally rub against the surface of an appendage A to which the apparatus 10 is strapped as the endless belt 110 travels along the path 129. Referring to
The spacing of the contact elements 130 and the length of the interaction segment 129s are preferably selected so that at least two contact elements 130 extend through the slot 309 in the housing 300 at all times as the endless belt 110 is driven in the machine direction 110m along the path 129. This helps limit front-to-back rocking of the apparatus 10 during use.
The bottom 300f of the housing 300 should be curved to conform to a human limb A with the slot 309 through the housing 300 extending along the longitudinal length Ax of the limb A for allowing the contact elements 130 to contact and effect parallel mobilization of a muscle or a tendon in the limb A as the contact elements 130 travel in the machine direction 110m along the interaction segment 129s of the path 129.
A band or strap 310 may be provided for temporarily securing the apparatus 10 to a human limb A with the slot 129s through the bottom 300f of the housing 300 extending along a longitudinal axis Ax of the limb A for allowing the contact elements 130 to contact a surface of the limb A and effect parallel mobilization of a muscle or a tendon under the contacted surface as the contact elements 130 travel along the interaction segment 129s of the path 129. The band or strap 310 may be elastic, inelastic or segmented with lengths of each.
The apparatus 10 may optionally include a heating unit for providing heat treatment to the area, and/or a vibration unit for providing vibrational treatment of the area along with the scraping parallel mobilization therapy.
The optional but preferred control system 200 is operable for controlling at least one operational parameter of the apparatus 10, allowing user input to establish the value of the at least one operational parameter, and display operational settings and/or performance values. The operational parameter may be one or more of travel speed of the endless belt 110, interval changes in travel speed, duration of travel of the endless belt 110 in the first machine direction 110m1 along the path 129, pauses in endless belt 110 rotation, etc.
The control system 200 can be programmed with an emergency stop whenever a voltage spike is observed, indicative of something caught in the endless belt 110.

Each therapeutic event as set forth can have a duration between about 2 and 30 minutes. Shorter durations tend to be less effective while longer durations provide diminishing returns at the risk of creating friction burn, skin abrasions, bruising, or otherwise injuring the skin. The treatment events are preferably periodically repeated throughout a treatment period. An exemplary treatment regimen is a therapeutic event frequency between once and four times every two days over a treatment period of at least seven days.
Referring to
An emollient can optionally be applied to the area to be scrapped just prior to use of the apparatus 10 to minimize surface friction.
One suitable treatment plan using the apparatus 10 is an eight-week treatment that combines consistent use of the apparatus 10 along with consistent stretching and strengthening exercises.
It is generally preferred to first rub an emollient on the area of the appendage A that will be treated. The instrument 10 is then placed onto the appendage A over the treatment area. The instrument 10 is preferably oriented, when possible, so that messages on the display screen 230 can be read while the instrument 10 is activated. Once the instrument 10 is activated, it may be repositioned slightly to find the injured area. The specific area treated by the instrument 10 may be adjusted for each session as desired. Markings may be provided on the exterior of the housing 300 to indicate the longitudinal start and stop points of scraping by the contact elements 130 for facilitating initial placement and subsequent adjustment of the instrument 10 on the appendage A.
