learned non-use
A behavioural phenomenon in which a patient suppresses use of a neurologically impaired limb due to repeated failed attempts, leading to functional disuse beyond what the neurological deficit alone would cause.
Full Definition
Learned non-use is a concept central to upper-limb neurorehabilitation, describing the conditioned suppression of movement in an affected extremity that develops when early post-injury attempts to use the limb are unsuccessful. Over time, the patient learns to compensate with the unaffected limb, reinforcing disuse of the impaired side even as neurological recovery occurs. This phenomenon is the primary theoretical rationale for Constraint-Induced Movement Therapy (CIMT). Editors should hyphenate the phrase as a compound noun ('learned non-use') and avoid the variant spelling 'learned nonuse', unless following an institutional style guide that omits the hyphen. The concept applies primarily to upper-limb rehabilitation after stroke or traumatic brain injury.
Usage
Usage note: Hyphenate as 'learned non-use' in all positions. Do not conflate with disuse atrophy, which refers to muscle wasting from inactivity rather than a behavioural suppression mechanism.
