Effects of low frequency repetitive transcranial magnetic stimulation on motor function and affective disorder in patients with Parkinson's disease / 中华老年医学杂志

ABSTRACT

Objective To investigate the therapeutic effects of low frequency repetitive transcranial magnetic stimulation (rTMS) on motor function and affective disorder in patients with Parkinson's disease (PD). Methods Twenty PD patients were performed by 1 Hz rTMS therapy for 15 days and 10 matched patients were performed sham stimulation. Hamilton Depression Scale (HAMD), Hamilton Anxiety Scale (HAMA) and Unified Parkinson' s Disease Rating Scale (UPDRS) were assessed before and 15 days after rTMS treatment. Results After treatment with rTMS, the motor function was improved, and UPDRS total score and UPDRS-Ⅰ , UPDRS-Ⅱ, UPDRS-Ⅲ scores were decreased. UPDRS score was decreased from (38.45±17.33) to (30.95± 17.00) (t=6.780,P<0.01). At the same time, HAMD score was decreased from (12.15±7.62) to (8.75±7.31 ) (t = 5.101, P<0.01 ). The scores of somatization, blockage and sleep disorders were lowered after treatment, but the HAMA score had no significant change(t=1.757, P>0.05). The rigidity of PD patients was improved obviously. All indexes had no improvement in sham stimulation group. Conclusions Low frequency rTMS may improve motor dysfunction and affective disorder in PD patients .
