This study investigated the immediate effects of two manual therapy approaches, myofascial release and the fascial distortion model, applied to the calf and plantar fascia in healthy adults. Participants were randomly assigned to one of the two intervention groups. Flexibility, balance, and postural control were assessed before and after the intervention to examine potential remote effects along the superficial back line. The purpose of this study was to compare the short-term functional effects of these two manual therapy techniques.
