deconditioning
Pronunciation: dee-kun-DISH-uh-ning
The physiological deterioration of cardiovascular fitness, muscle strength, and functional capacity resulting from prolonged inactivity or bed rest, particularly prevalent in hospitalised older adults.
Full Definition
Deconditioning describes the multisystem physiological decline — encompassing reduced aerobic capacity, muscle atrophy, orthostatic hypotension, decreased bone density, and impaired balance — that occurs as a direct consequence of physical inactivity, most commonly prolonged bed rest during hospitalisation. In geriatric rehabilitation, deconditioning is both a presenting problem and a risk that must be actively countered during the admission itself. Editors should note that 'deconditioning' is one word (no hyphen) and that the verb form is 'deconditioned' as an adjective ('a deconditioned patient'). The term should not be used interchangeably with 'sarcopenia', which specifically denotes age-related muscle loss independent of acute inactivity.
Usage
Usage note: One word, no hyphen. The adjective form 'deconditioned' is standard. Distinguish from 'sarcopenia' (age-specific) and 'frailty' (broader syndrome).
