The pattern of hip muscle activation changed towards normal during recovery from stroke in most patients. Use of compensatory strategies early after stroke in these subjects did not prevent return of normal patterns of muscle activation later.

The latency of GRF onset after a push at the hips in controls and in stroke subjects is related to sway and both measurements increase after a stroke. This test offers a method of measuring balance after a stroke, and serial testing of an individual after a stroke may prove a useful measure of an individual's recovery of balance.
