Additional power training in patients with Parkinson's disease:a randomized controlled trial
Objective:To compare the effects of power training combined with routine training(PRT)and routine training alone(RT)on motor symptoms,strength,balance,functional performance,and quality of life in patients with Parkinson's disease(PD).Methods:A total of 39 patients[Hoehn and Yahr=1-3;Unified Parkinson's Dis-ease Rating Scale-Ⅲ(UPDRS-Ⅲ)=21.61±7.64]were randomly assigned to the PRT group(n=20)or RT group(n=19)involving 3 times/week(Monday,Wednesday,Friday)of supervised training for 4 weeks.Including stretching,strength,balance,gait trainingas in the RT group,6 instruments were used to provide low-load,high-velocity power training for the PRT group.The UPDRS-Ⅲ,quadriceps femoris extension(E)and hamstring flex-ion(F)peak torque(PT),total power(TP),and average torque(AT),Berg Balance Scale(BBS),Timed Up-and-Go test(TUGT),5 times sit-to-stand test(FTSST),and the 39-item Parkinson's Disease Questionnaire(PDQ-39)were measured at baseline and on the day after the completion of 4-week training.Results:Both training groups showed significantly better scores(P＜0.05)on the UPDRS-Ⅲ,EPT,ETP,EAT,FPT,BBS,FTSST,and PDQ-39 after training.No significant differences were detected between the PRT and RT groups.Conclusion:Both PRT and RT programs can significantly improve physical performance and quality of life in patients with PD.PRT showed no advantage over RT.
