Abstract: Objective To explore the effects of low load exercise on the gait and balance in patients with Parkinson's disease. Methods 12 inpatients with Parkinson's disease from May to August, 2015 accepted low load exercise on Power Rehabilitation System 14 times in 2 weeks, with the medication as before. They were assessed with 3D gait analysis and Berg Balance Scale before and after treatment. Results The step length, stride length and walking speed improved after treatment (P<0.05), and improved more in the seriously affected limbs. There was no difference in cadence, stride time, step time, single support, double support, opposite foot off and opposite foot contact after treatment (P>0.05). The scores of Berg Balance Scale improved after treatment (P<0.05). Conclusion The low load exercise can improve the gait and balance in patients with Parkinson's disease.
