In discriminative sensory reeducation after median nerve repair, which method is BEST for reeducation of discriminative sensibility?

• A. Identify items by touch both with and without vision on a daily basis.
• B. Educate the client to avoid working around machinery.
• C. Advise the client to use vision to compensate for sensory loss.
• D. Educate the client to avoid temperatures below 60°.

Answer: (A)

Discriminative sensory reeducation focuses on retraining the brain to interpret touch by actively identifying objects through the sense of touch, reducing reliance on vision as the primary cue. The best approach is daily practice in identifying everyday items by touch, ideally starting with some visual help and then progressing to perform the tasks with vision occluded. This repeated, progressive tactile discrimination helps the brain re-map sensory input from the repaired median nerve, improving texture, shape, and size recognition and restoring discriminative sensibility.

Other strategies aren’t addressing the learning process. Safety guidance around machinery is important but not a method to retrain touch. Using vision to compensate for sensory loss avoids rebuilding tactile processing, and avoiding exposure to colder temperatures is protective rather than rehabilitative for discriminative touch.
