From: Peroneal muscle activity during different types of walking
Demonstration of both walks on a medial incline ramp; a. Walking on an incline ramp, plantar surface of the foot is fully placed on the walking surface – FULL; b. Walking on an incline ramp, lateral part of the foot elevated – LAT. Force, peroneal muscles - \( {\overset{\rightharpoonup}{F}}_{PL+ PB} \); Force, ground reaction - \( {\overset{\rightharpoonup}{F}}_{GR} \); Lever arm, peroneal muscles - rPL + PB; Lever arm, ground reaction force - rGR
