Neural and muscular factors both contribute to plantar-flexor muscle weakness in older fallers

Jean-Baptiste Mignardot

Plantar-flexor muscles are key muscles in the control of postural sway. Older fallers present lower maximal plantar-flexor performance than older non-fallers; however, the mechanisms underlying this motor impairment remain to be elucidated. This study aime ...
