Abstract
AIM: Facial expressions are often impaired in patients with Parkinson's disease (PD). Few studies have examined the effects of head and neck rehabilitation in patients with PD using a facial expression analysis. In the present study, to further elucidate the effects of facial rehabilitation exercise in patients with PD, a three-dimensional facial expression analysis with FaceReader™ and surface electromyography (EMG) were performed in order to assess the facial expressions and muscle activities, respectively. The effects of such exercises on the mood and mental health were also evaluated. METHOD:Twenty-one patients with PD (63.3±12.1 years) participated in the present study and were randomly assigned to an intervention group and non-intervention group. Facial rehabilitation exercise was performed for 60 minutes once a week for 12 weeks in the intervention group. GHQ-12, the facial expression analysis with FaceReader™, surface EMG, and the VAS scale for mood changes were used to evaluate the effects of the program. The results from both groups were compared. RESULTS: The results from eight patients in the intervention group and five in the non-intervention group were analyzed. FaceReader™ revealed a higher "Happy" index and lower "Sad" index in the intervention group than in the non-intervention group, and a significant interaction "Happy" index by an analysis of variance was noted between the two groups. EMG also showed increases in the activity of facial muscles in the intervention group. The subjects' mood improved after each facial rehabilitation exercise session. CONCLUSION: The results of the present study suggest that the facial rehabilitation exercise affected the mood, facial expression, and facial muscle activities in patients with PD and indicate that the expression analysis with the FaceReader™ and surface EMG are useful for evaluating the effects of facial rehabilitation exercise.
