The Effect of Achilles Tendon Stretching on Weightbearing

Introduction The gastrocsoleus complex via the Achilles tendon exerts a plantar flexion moment on the foot and ankle. The manifestation of this moment on the forefoot during gait is that of plantar pressure. Stretching is routinely recommended by physicians to provide relief of forefoot pain, heel pain and plantar fasciitis, as well as being advised prior to sporting activities to minimize injury potential. However, the effect of Achilles stretching on weight bearing has not been studied. Therefore, the following hypotheses are examined for normal subjects; 1) Achilles stretching exercises will, shortly after stretching, result in no increase in passive dorsiflexion of the ankle, and 2) Achilles stretching exercises will, shortly after stretching, result in no change in either the spatial or temporal plantar pressure distribution during gait. This is accomplished by documenting the dorsiflexion range of motion and plantar pressures during gait both prior to and directly after Achilles stretching exercises.
