The aims of this study are to: (1) determine muscle activation of the tibialis posterior muscle during different common gastrocnemius stretches and (2) radiographically quantify the tibial-calcaneal angle during the common stretching positions. We hypothesize that stretching over the edge of a step with the arch supported will minimize the activation of the tibialis posterior muscle in addition to increasing the tibial-calcaneal angle.
