Hip extension power and abduction power asymmetry as independent predictors of walking speed in individuals with unilateral lower-limb amputation.

Background: Preferred walking speed (PWS) is an indicator of walking ability, prosthetic walking potential, and function following a lower-limb amputation (LLA). There is a link between lower-limb muscle performance and PWS in individuals with LLA. However, the ability of select hip muscle performance parameters to determine PWS in these individuals still needs to be thoroughly investigated.
