Increasing Hamstring Range of Motion via Plantar Myofascial Release: A Critically Appraised Topic

Abstract

Context: The concept of anatomical fascial trains and myofascial release are heavily researched topics independently. However, few studies have determined if myofascial release of remote areas can cause lengthening throughout more distal aspects of these fascial trains. Clinical Question: In healthy individuals, what is the effect of myofascial release on the plantar aspect of the foot in improving flexibility and hamstring length as determined by a sit-and-reach test? Clinical Bottom Line: The usage of myofascial release on the plantar aspect of the foot via a firm object has been shown to improve sit-and-reach distance. Each article included for analysis utilized similar methods of instructing self-myofascial release with regard to time as well as type of object used for the intervention. Though this was consistent between studies, the authors should have implemented secondary outcome measures. Despite the limitations to each of the studies analyzed, there is a Strength of Recommendation Taxonomy (SORT) Level B evidence to support the implementation self-myofascial release to the plantar fascia. This intervention should be considered a concurrent option for individuals with range of motion deficits or fascial restrictions in the upper thigh.
