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

##article.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.
