Abstract
Abstract A therapeutic wrist support is provided allowing a person with carpal tunnel syndrome to manipulate the wrist without further aggravating this ailment. The device employs a flexible substrate which includes integral splint elements physically positioned to allow limited wrist movement in both vertical and horizontal directions with respect to the longitudinal axis of the wearer's forearm. Positioning of the splint elements is also made dependent upon whether the left or right wrist of the wearer is involved.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
209 words
A remedial device for treatment of carpal tunnel syndrome which permits limited wrist mobility by the wearer in both vertical and horizontal directions comprising in combination: (a) a flexible substrate sized to fit entirely around the wearer's forearm to form upper, lower and side portions when secured in place and which extends longitudinally at one end from a location below the wearer's elbow to an opposite palm end approaching the metacarpal joints of the wearer's hand, the palm end further terminating in an elastic cuff gripping the wearer's hand while also including a projection extending forwardly therefrom at the wearer's thumb before the device is secured in place but extending backwardly therefrom when secured in place, (b) a cushioning pad joined to the flexible substrate in the palm region, (c) a first longitudinally extending splint restraining excess vertical mobility of the wearer's wrist and joined to the flexible substrate in the upper portion, (d) a second longitudinally extending splint restraining excess horizontal mobility of the wearer's wrist and joined to the flexible substrate in a predetermined side portion, and (e) releasable fastening means joined to the flexible substrate enabling the side portions to be secured together while also enabling the hand projection to be secured to the top portion.
