Bridging the Stomatognathic-Postural Link: Physiological Mechanisms of Remote Myofascial Effects on Hamstring Range of Motion

Abstract

Executive Summary
This comprehensive research paper investigates the physiological and anatomical links between the
stomatognathic system comprising the temporomandibular joint (TMJ) and associated cranio-cervical
structures and distal lower limb flexibility, specifically hamstring range of motion (ROM). The study is
framed within the theory of myofascial meridians, with a particular focus on the Superficial Back Line
(SBL) as a continuous conduit for mechanical force transmission and neurophysiological modulation.
Through a synthesis of current literature, the report examines the role of suboccipital Inhibition,
sensorimotor modulation, and stretch tolerance in mediating remote effects. A pilot case analysis,
utilizing a synthetic dataset of 60 athletes, compares the efficacy of TMJ-region myofascial release
(MIR) against traditional static hamstring stretching. The findings reveal that while direct local
stretching remains the gold standard for specific flexibility gains, remote TMJ-region interventions
produce significant improvements, supporting the existence of a functional stomatognathic-postural
link. The clinical implications highlight the utility of integrated, remote interventions as adjuncts in
sports rehabilitation, particularly when local treatment is contraindicated or limited by pain and
apprehension.
