Introduction:
The prevalence of temporomandibular disorder (TMD) among Parkinson's disease (PD) is relatively high, but deep cervical muscle endurance, trunk position sense, and swallowing performance in PD with TMD is still lacking. The aim of the study was to compare deep cervical flexor muscle endurance, trunk position sense and swallowing disorders in PD with and without TMD.
Method:
The study was conducted in 80 persons with PD. The patients were divided into two groups based on TMD. Trunk position sense was assessed with a digital inclinometer, temporomandibular joint dysfunction with 'Helkimo Clinical Craniomandibular Index', deep cervical muscle endurance with 'Cranio Cervical Flexor Test', and swallowing disorder with Eating Assessment Tool-EAT 10'. All patients were tested during the 'on' phase following drug therapy.
Results:
No significant differences were found in trunk position sense, deep cervical muscle endurance and swallowing performance between the groups (p > 0.0071).
Conclusion:
It was shown in the study that trunk position sense, deep cervical muscle endurance and swallowing performance didn't change in PD with TMD. The absence of significant differences in trunk position sense, deep cervical muscle endurance, and swallowing performance between the groups suggests that Temporomandibular dysfunction (TMD) appears not to impose further impact on these parameters in individuals diagnosed with Parkinson's disease.
