Problems solved by technology

[0025] CTS and its associated dissonances are responsible for high corporate overhead in terms of reduced productivity, workers' compensation, and associated medical costs
This medical cost comes from having to subsequently treat symptoms that often become chronic due to traditional CTS diagnosis and treatment paradigms

Embodiment Construction

[0037] The following detailed description illustrates the best mode currently contemplated for carrying out the invention. This description is not intended in a limiting sense, but for the purpose of illustrating the general principles and best mode of the invention, as the scope of the invention is best defined by the appended claims.

[0038] The present invention includes a dynamic orthotic device and method for CTS correction wherein the device impedes palm sliding during finger extension / flexion without inhibiting hand, wrist and forearm motion during normal activities of daily living. A person with the device can perform wrist and hand extension / flexion, forearm supination / pronation, and hand radial / ulnar deviation without restriction. Existing techniques focus on flexion / extension of the wrist, ie providing resistance to rotational motion about the wrist, but do not address VCT during flexion / extension of the fingers. When a person with CTS extends a finger ("finger ex...

Abstract

The present invention provides an orthotic appliance for the carpus of a human hand for the treatment of a carpal tunnel syndrome condition using co-dynamic, rather than traditional static or dynamic, techniques. The appliance may apply a dorsally-directed force to 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 restricting arc of motion or 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] Horizontal citations to related applications [0002] This application claims the benefit of US Provisional Patent Application Serial No. 60 / 605674 with a priority filing date of October 20, 2004. technical field [0003] The present invention relates generally to orthoses and splints for the human wrist and, more particularly, to an orthotic device for the treatment of carpal tunnel syndrome using dynamic and co-dynamic rather than static techniques. Background technique [0004] Carpal tunnel syndrome ("CTS") results from compression of the central nervous system. This central nerve runs through the area in the wrist of the hand between the carpal bone and a ligament called the flexor retinaculum. This compression causes pain, numbness, tingling and weakness in the hand. CTS often refers to pain and paresthesias in the arms, shoulders, and neck. [0005] There are many theories about the cause of CTS. Some believe it results from inflammation of the gill bursa, ...
