A loss of balance, as shown by inability to maintain the total body center of mass (COM) position over the base of support (feet) during standing or walking, may lead to a fall. Stepping strategy has been found to be a strategy of choice for fall recovery in both younger and older adults. Both support and swing legs contribute to the successful recovery of a fall. Control of the lower-limb joints and coordination of multiple muscles are means for fall recovery that redirect the ground reaction force relative to the total body COM.
