AI Technical Summary

Problems solved by technology

First, the splint is uncomfortable, which reduces patient compliance with the splint
Second, by limiting the range of motion of the patient's hand, static splints limit the types of work the patient can do and interfere with normal activities of daily living
Third, static splinting can only relieve CTS symptoms for a limited time, and long-term immobilization is generally associated with complications
Michniewicz does provide a more comfortable and less restrictive device than some other static splints, but still does not address the underlying CTS cause

Embodiment 300

[0059] Embodiment 300 may allow a person to place the appliance around a person's wrist and forearm without assistive tools. The two palm straps 440 may have a resistance means 442 such that the resistance means 442 hold the palm straps 440 in place when the palm straps 440 are secured to the palm of the hand by pulling their ends 441 through the resistance means 442, Such that the resistance device does not return to its previous position when the pulling force is removed. like Figure 16As shown, the resistance means 442 is a fabric loop sewn onto the flexible tube 430 with a hole slightly narrower than the width of the palm strap 440 so that it can apply resistance to pulling or loosening the palm strap 440. Other resistance devices 442 known in the art may be used without departing from the scope of the present invention; for example, a clasp (not shown) having a toothed movable cross member that Can be moved in a pulling direction, and the teeth can engage the palm stra...

Abstract

The present invention provides an orthotic appliance for the carpus of a human hand for the treatment of carpal tunnel syndrome using co-dynamic, rather than traditional static or dynamic, techniques. The appliance may apply a 2 pound dorsally directed force about the region of the pisiform bone (23) in the neutral carpal position of a human hand upon co-contraction of the hand and up to 8 pounds dorsally directed during arc of motion in carpal flexion, as the wrist and hand is encouraged to actively move in all planes of motion without negatively affecting the normal activities of daily living. The appliance may comprise a biasing structure for applying the dorsally directed force and a base structure for maintaining the biasing structure in its proper configuration during normal hand motion.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Application No. 10 / 352,837, filed January 28,2003. technical field [0003] The present invention relates generally to the field of orthotics of the human carpal bone and splints; more particularly, to orthotic appliances for the treatment of carpal tunnel syndrome utilizing dynamic and co-dynamic rather than static techniques. Background technique [0004] Carpal Tunnel Syndrome ("CTS") is a condition that results from compression of the median nerve in the carpal area of ​​the hand between the carpal bone and a ligament called the flexor retinaculum. This compression causes pain, numbness and tingling in the hand, and a weak grip. CTS often causes pain and paresthesias in the arms, shoulders and neck. [0005] There are many theories about the cause of CTS. Some believe that repetitive motion-induced swelling of the carpal tunnel is caused by inflammation of the bursa, tendon...
