The relationships between weight-bearing asymmetry after stroke, motor function and activities of daily living

A survey of 90 stroke patients was undertaken to examine the pattern of weight distribution when standing and its relationship with motor function and independence in self-care activities. Weight distribution was measured with a computerised limb load monitor, motor function with the Rivermead Motor Assessment Scale and activities of daily living (ADL) with the 10-point ADL scale. Stroke patients showed an asymmetry in weight distribution, with the majority (79%) favouring the unaffected leg. The degree of asymmetry correlated significantly with motor function (rs= -0.45, P<0.001) and ADL (rs= -0.35, P<0.001). The results support the treatment goal currently used by both physiotherapists and occupational therapists of re-educating the symmetrical stance of stroke patients. It is noted that further studies are needed to evaluate therapists' success in achieving this goal.
