peroneus tertius

The muscle arising from the anterior portion of the distal one third of the tibia and the adjacent portion of the interosseous membrane and attaching on the dorsal surface of the fifth metatarsal. The peroneus tertius is a secondary contributor to ankle dorsiflexion and eversion. This muscle is absent in a significant proportion of the population.

The single best electrode combination suggested by this study consists bilaterally of the gastrocnemii coactivated with the peroneus longus (using a branched intramuscular electrode), the tibialis anterior coactivated with the peroneus tertius (via stimulation of the deep peroneal nerve), all of the vasti coactivated with the rectus femoris (via stimulation of the femoral nerve), and intramuscular electrodes in the semimembranosus, gluteus maximus, gluteus medius (with emphasis on the anterior portion), adductor magnus (with emphasis on the superior portion), and erector spinae.
