Temporomandibular Joint Dysfunction and Impaired Stomatognathic Alignment: A Problem Beyond Swallowing in Patients...

The aim of this study is to evaluate the efficacy of supervised structured exercise programme in post stroke patients with temporomandibular joint dysfunction (TMJD). 30 post stroke patients diagnosed as TMJD according to "diagnostic criteria for temporomandibular disorders" (DC/TMD) were included for the study. A structured exercise programme including active and active-assisted range of motion (ROM) exercises for neck and temporomandibular joint (TMJ), chins tuck exercises, breathing and relaxing exercises and posture exercises were performed. Cervical ROMs including flexion, extansion, lateral flexion and rotation, Mann assessment of swallowing ability (MASA) and mini mental state exam (MMSE) scores, maximal mouth opening (MMO) and craniomandibular index (CMI) of the patients compared at baseline, 1st and 6th month after supervised rehabilitation procedure. All parameters were significantly improved both in 1st and 6th month evaluation. At 6th month evaluation, the cervical ROMs of the patients improved from severe to mild restriction (p = 0.001), the mean MASA score of the patients improved from moderate to mild swallowing disorder (p = 0.001), mean MMSE score of 30 patients was accepted as normal (p = 0.001), mean MMO of the patients was 56.00 ± 4.84 mm and mean CMI was 0.16 ± 0.05 indicating that the patients had a "mild" limitation in mouth opening and "mild" dysfunction in TMJ (p = 0.001 respectively). Our structured supervised exercise programme improves swallowing quality by establishing proper stomatognathic alignment and TMJ function.
