Comparative Study Of The Effects Of Lower Limb Rehabilitation Robot And Leg Cycle Ergometer On Freezing Of Gait In Parkinson's Disease

Objective:To assess and compare the rehabilitation effects of lower limb rehabilitation robot and leg cycle ergometer on freezing of gait(FOG)in Parkinson's Disease(PD).Methods: A Pilot randomized controlled trial.Twenty-two patients with PD-FOG at Hoehn & Yahr stage 2-3,diagnosed in the First Affiliated Hospital of Dalian Medical University from December 2017 to August 2019,were randomly divided into two groups,and received rehabilitation treatment at Dalian Port Hospital.The two groups of patients maintain the original drug therapy or DBS parameter scheme unchanged.The basic rehabilitation training of two groups are the same--Physical Therapy(PT),including: muscle tension relief,posture correction,balance training,recumbent transfer training,etc.Treatment frequency was 5 times a week for 30 minutes each time,for a total of 2 weeks,10 times.(1)The robot group was given PT and lower limb robot training,5 times a week for 30 minutes each time,for a total of 2 weeks,10 times.For patients who cannot independently complete the walking of the lower limb rehabilitation robot running platform,they are suspended,and give them 20-30% weight support for the first 5-10 minutes,and set the pace to 0.2-0.5 km / h,and then gradually reduce the weight support to 0-10%,the pace Gradually increase to 1.5-2 km / h.All patients were trained under the same visual cue module or game module.Patients who can complete walking on the treadmill can directly add visual cue modules and game modules while walking.(2)The control group received conventional PT and leg cycle ergometer training,5 times a week,30 minutes each time,a total of 2 weeks,10 times.Evaluation tools and methods: Two groups of patients were evaluated before,immediately after the treatment.Primary assessment includes: The Unified Parkinson's Disease Rating Scale(UPDRS)3.0 score,UPDRS-? score,Parkinson's disease Patient quality of life questionnaire 39(PDQ-39),Freezing of gait questionnaire(FOG-Q),5m standing-walking-sitting duration(5m-SWS),Gait parameters(step speed,step length,step width).Results: 1.The robot group's UPDRS score,UPDRS-? score,PDQ-39 score,FOG-Q score,5m-SWS duration,step speed,and step length were significantly improved after treatment(P <0.05).In terms of step width,There was no significant difference in the robot group before and after treatment(P> 0.05).2.The control group's UPDRS score,UPDRS-? score,PDQ-39 score,FOG-Q score,5m-SWS duration and step speed,step length,and step width were significantly improved after treatment(P <0.05).3.After treatment,compared with the two groups,There were no significant differences between the two groups in UPDRS score,UPDRS-? score,5m SWS,PDQ-39 score,FOG-Q score,stride length,pace,and step width(P> 0.05).Conclusions: 1.Whether using lower limb rehabilitation robot + PT,or leg cycle ergometer training + PT,freezing of gait in Parkinson's disease can be improved very well,the overall motor function and quality of life of the two groups of PD-FOG patients were significantly improved,and the effect is equivalent.2.In terms of gait parameters: both lower limb rehabilitation robot and leg cycle ergometer can improve the stride length,pace of PD-FOG patients with equivalent effects;leg cycle ergometer can shorten step width of PD-FOG patients,the effect of lower limb rehabilitation robots on step width varies.
