Clinical study of treating Parkinson disease by repetitive transcranial magnetic stimulation / 临床神经病学杂志

ABSTRACT

Objective To study the efficacy and safety of treating Parkinson disease(PD) by repetitive transcranial magnetic stimulation (rTMS). Methods 45 patients with PD were randomly divided into two groups. 30 patients received rTMS therapy and 15 patients were given sham stimulation. Stimuli were delivered at an intensity of 110% of resting threshold (RT) and a frequency of 1Hz once a day for 10 days. All the patients were followed-up at 1 month and 3 months after treatment. The efficacy was assessed by UPDRS score, grooved pegboard test, timed motor test and 10m turned back test. All the patients stopped using dopaminergic drugs for at least 12h before each assessment. Results In rTMS treatment group, the UPDRS total scores, UPDRSⅠ-Ⅲ, the mean times of grooved pegboard and 10m turned back test were significantly decreased 10 days after treatment compared with pre-treatment (all (P)0.05), and PDQ scores significantly decreased 3 months after treatment. In sham treatment group, there was no difference of each index between pre- and post-sham treatment.Conclusion Low frequency rTMS may improve the symptoms of the patients with PD and raise their quality of life.
