An OT practitioner is measuring the starting position of passive proximal interphalangeal (PIP) joint flexion in a client who has increased flexor tone in his wrist and fingers after a traumatic brain injury
The therapist should place the client's wrist in which position?
A. Neutral or flexion
B. Slight extension
C. Full extension
D. Any position, because wrist position has no effect on finger motion
ANS: A
Placing the wrist in neutral or flexion will put the tight long flexors on slack, thus reducing the effect of muscle tightness on extending the PIP joints. Placing the wrist in extension will cause passive insufficiency where PIP extension will be limited by the length of the long flexor muscles crossing the wrist and fingers.
