More than one million Americans receive treatment for Plantar Fasciitis every year. And a recent study showed that 80 percent of plantar fascial patients still had symptoms 12 months after the original injury. Muscle tightness in the lower leg is a significant contributor, specifically the calf muscles (gastrocnemius and soleus). These muscles develop trigger points (‘knots’ in the muscle) that affect foot biomechanics leading to excessive strain on the heel. If this issue is never addressed, it’s unlikely that the issue will fully resolve on its own.
Acupuncture helps by deactivating any trigger points and restoring proper functioning to the muscles involved. Furthermore, specific stretching exercises can help lengthen muscle fibers and increase range of motion.
See this ARTICLE for specifics on the the types of stretches that were studied.
