Deconditioning
The physiological deterioration of musculoskeletal, cardiovascular, and metabolic function resulting from prolonged inactivity or immobility, commonly targeted in rehabilitation programs.
Full Definition
Deconditioning describes the constellation of adverse physiological changes—including decreased muscle strength and endurance, reduced cardiovascular fitness, bone demineralisation, and altered metabolism—that occur as a direct consequence of enforced or voluntary physical inactivity. In PM&R, deconditioning is a common secondary diagnosis in patients admitted for primary conditions such as hip fracture, stroke, or prolonged ICU stay, and it profoundly affects rehabilitation prognosis and the intensity of therapy required. Editors should note that 'deconditioning' is a single, unhyphenated word in both noun and verb forms ('to decondition'). It is distinct from the primary diagnosis and should not be used interchangeably with 'weakness' or 'fatigue.' Documentation of deconditioning is important for justifying rehabilitation intensity and duration to payers.
Usage
Usage note: Spell as one unhyphenated word. Do not conflate with 'debilitation,' which is a broader clinical term. When used as a verb, 'decondition' is acceptable in PM&R literature.
