What is learned non-use?

What is learned non-use?

• A. Neural regeneration after injury.
• B. Increased use of an unaffected limb.
• C. Disuse of an impaired limb due to failure or adverse experiences.
• D. A compensatory strategy learned through practice.

Answer: (C)

Learned non-use occurs when an injured or weakened limb is repeatedly tried and fails to perform well, leading the person to stop using that limb and rely on the other, healthier limb. The repeated negative experiences teach the brain that using the affected limb isn’t worthwhile, so use of the impaired limb declines and may become hard to reverse, even if some usable function remains. This is about disuse driven by past failure, not about neurons regrowing, nor about simply using the other limb more, nor about a deliberate compensatory habit learned through practice. Therapies like constraint-induced movement therapy aim to counteract this by forcing use of the affected limb to reestablish function.
