contracture
Pronunciation: kon-TRAK-cher
A permanent or semi-permanent shortening of muscle, tendon, or joint capsule tissue resulting in restricted range of motion, commonly arising from prolonged immobility in geriatric patients.
Full Definition
Contractures develop when soft tissues around a joint lose their normal extensibility due to sustained positioning, immobility, spasticity, or fibrosis, ultimately limiting passive and active joint movement. In geriatric rehabilitation, contractures are both a complication of acute illness and a barrier to functional recovery, commonly affecting the hip, knee, elbow, and hand. Prevention through regular repositioning and passive range-of-motion exercises is a key nursing and therapy goal during inpatient stays. Editors should note that 'contracture' is not interchangeable with 'spasticity' — the latter refers to velocity-dependent muscle tone, whereas contracture refers to structural tissue changes. The term is always a noun; there is no standard verb form in clinical English ('to develop a contracture' rather than 'to contracture').
Usage
Usage note: Always a noun — avoid verbing ('to contracture'). Distinguish clearly from 'spasticity' and 'rigidity' in clinical editorial copy.
