Abstract
We determined the amount of saliva secretion, its pH and of salivary alpha-amylase concentrations in 20 patients with Parkinson′s disease before and after the music therapy performed for 1 hour. Music therapy included passive one by hearing music and active one by singing and playing percussion instruments under the guide of music therapists. Evaluation of mood determined by use of visual analog scale revealed that 80% of participants felt happy after the therapy. Amount of saliva and alpha-amylase concentration did not change significantly after the therapy. In contrast, pH of saliva increased significantly after the therapy. Increased stress and sympathetic nerve predominant state have been reported to reduce saliva secretion, increase amylase concentration and reduce saliva pH. Results of our study suggest that active music therapy makes mood happy and increases saliva pH in patients with Parkinson′s disease.
