Instructions:
The length of the tape was measured from 2 cm inferior to the medial epicondyle of the humerus to the wrist joint line. A roll of tape was cut into a strip and then cut down the middle of the strip to produce 2 tails or a "Y-strip." The Y-strip was applied to the common wrist flexor muscle from its insertion to its origin with 15-20% stretch tension. To standardize the stretch tension, we measured the distance between the line 2 cm distal to the medial epicondyle of the humerus and the wrist joint line, and then we multiplied the distance by 0.8 to make the length of the tape. The first tail of the Y-strip was applied to the middle of the forearm with the wrist in a hyperextended position and with the elbow in full extension and supination. The second tail of the Y-strip, with the same stretch tension, was taped along the medial edge of the forearm to wrap the common wrist flexor muscles.
