Circumduction
Pronunciation: ser-kum-DUK-shun
A compensatory gait deviation in which the entire lower limb is swung outward in a semicircular arc during the swing phase to advance the foot.
Full Definition
Circumduction is observed when a patient cannot adequately flex the hip and knee or dorsiflex the ankle to achieve sufficient ground clearance during the swing phase of gait. It represents a compensatory strategy for foot drop, rigid knee, or an excessively long orthosis. In orthotics reports and gait analysis documentation, the term is used as a specific deviation descriptor. Editors must not confuse circumduction with 'hip hiking' (pelvic elevation) or 'vaulting' (rising on the contralateral toe), both of which are alternative compensatory strategies.
Usage
Usage note: Not to be confused with 'circumduction' in joint range-of-motion testing, which describes a circular movement at a ball-and-socket joint. Context determines meaning.
