Effects of treadmill incline and speed on peroneus longus muscle activity in persons with chronic stroke and healthy subjects

Peroneus Longus (PL) muscle provides frontal plane stability during walking [1], most prominently seen in the single support phase [2]. PL with other ankle invertor and evertor muscles together maintain balance control in the frontal plane [3] and their activity significantly increases when standing on unstable surfaces [4]. Excessive activity in peroneus muscles can result in greater eversion moments and produce large medio-lateral displacements of the body [5]. Balance impairments are most commonly seen in the form of excessive medio-lateral sway in the frontal plane in persons post-stroke [6].
