Relation of IBS & TMJ: The nexus is hyper-mobile joints. TMJ occurs in TM joint of face uppermost in people who chronically tilt head; oft associated w. scoliosis (common in #HSD) & d/t Masseter muscle spasm attempting to maintain normal dental occlusion.
#IBS is associated with ligament laxity of SIJ & autonomic nervous system impingement within contiguous presacral plexus, which tracts to intestine; #IBS is a #dysautonomia. These are my clinical observations and theories
In patients with only complaint of TMD (Temporal Mandibular Joint, TMJ, Disorder) there seems to be near universal generalized joint hypermobility (#HSD). TMD seems to occur mostly in women.
In persons who complain only of symptoms that prove to be #IBS, the near universal finding is sacroiliac joint (SIJ) hypermobility.
IBS in men is unusual; usually related to severe mechanical injuries of pelvis; that loosened their sacroiliac joints. I published study of 20 young men with #IBS. They all pursued extreme sports (mostly skateboarders), had significant buttock falls & unstable SIJ’s.
I predict an epidemic of #IBS in young males related to modern extreme sports of skateboarding, motocross, dirt biking, mountain biking, snowboarding, etc.
TMJ oft associates with #HSD. My clinical findings in dozens of patients with TMJ & HSD: functional scoliosis (remits reclined); one shoulder lower; head tilted to lower shoulder; TMJ on up-side of head. My theory: jaw proprioception preserves equal dental occlusion both sides..
In order to maintain symmetric dental sulci occlusion, Masseter muscle face-up side contacts in chronic spasm; raises ipsilateral mandible vs. gravity. Oft see asymmetrical face w. more prominence ipsilateral cheek. As spastic Masseter closes TMJ exerts excess/asymmetric force...
Forceful asymmetric TMJ closure burnishes mandible condyle vs. rim of TMJ fossa, which is naturally shallow joint cavity endowed with a cartilaginous rim to provide greater depth as female aspect of TMJ. Over time the rim becomes degraded & joint sloppy & prone to subluxation ...
IMO pain of TMJ disorder is generated by stretched joint ligaments & chronic muscle spasm of associated Masseter. Therapy: SIJ belt to stabilize pelvis, Yoga for back muscles; perhaps shoe lift lower shoulder side, shrug ex’s to tone lower shoulder S. trap. muscle ...
CONT: massage, biofeedback to spastic Masseter; chewing gum on face-down side to correct crossed muscle syndrome of Masseters; perhaps a night dental splint; Cannabis lotion to spastic Masseter; correction of chronic head tilt, etc. ...
TMJ disorder is example of asymmetry of upright body tower often seen in those with #HSD, which is associated with #fibromyalgia. Head weighs ~10# & is at top this tower. Is also example of effect of gravity force on those who have soft tissue laxity variations (hypermobility).
TMJ disorder is terribly painful. There are probably as many theories of etiology as there are doctors & dentists (D&D) interested in this problem; by far a minority of D&D are even interested in this disabling disorder.
