title: Conservative care of temporomandibular joint disorder in a 35-year-old patient with spinal muscular atrophy type III: a case study.
abstract: OBJECTIVE
  This article describes the chiropractic clinical management and therapeutic benefits accruing to a patient with temporomandibular joint (TMJ) disorder and spinal muscular atrophy type III.
  
  
  METHODS
  A 35-year-old white man presented at the university chiropractic outpatient clinic with a complaint of masseter muscle pain and mouth-opening restriction. Temporomandibular joint range of motion evaluation revealed restricted opening (11 mm interincisival), and pain was rated by the patient at an intensity of 5 on a pain scale of 0 to 10.
  
  
  RESULTS
  Chiropractic care was provided and included TMJ mobilization, myofascial therapy, trigger point therapy, and light spinal mobilizations of the upper cervical vertebrae. Final evaluation of TMJ range of motion showed active opening of 12 mm with absence of pain and muscle tenderness of the jaw.
  
  
  CONCLUSIONS
  This case suggests that a patient with musculoskeletal disorders related to underlying neurodegenerative pathologies may benefit from chiropractic management adapted to their condition. In the present case, chiropractic treatment of the TMJ represented a viable, low-cost approach with limited adverse effects compared with surgery.
