Abstract
[Purpose] This study investigated the effects of stomatognathic alignment exercise on temporomandibular joint function and swallowing function of stroke patients presenting limited mouth opening. [Subjects] Fourteen subjects with post-stroke hemiparesis presenting limited mouth opening were randomly assigned to either the experimental group or the control group, with 7 subjects in each group. [Methods] Subjects in the experimental group participated in a stomatognathic alignment exercise program that consisted of mobility exercises of the TMJ and neck and postural correction. Main outcome measures were neck mobility, the active maximum range of mouth opening, the craniomandibular index (CMI), and the Mann assessment of swallowing ability (MASA) score. [Results] The changes in the values of the range of mouth opening, CMI, MASA, and all the parameters of neck mobility were significantly different between the groups. Furthermore, post-test values appeared to be significantly different for the range of mouth opening, the craniomandibular index, and the MASA scores between the groups (p>0.05). [Conclusion] Stomatognathic alignment exercise may improve TMJ function and swallowing function of patients with post-stroke hemiparesis.
