Gait training after stroke using the Lokomat rehabilitation robot

摘要

Objective To investigate the effect of Lokomat gait training rehabilitation robot on joint motion and lower limb function in hemiplegic patients after stroke.Methods Forty hemiplegic patients after stroke were randomized equally into a robotic group and a control group (20 cases in each group).The robotic group received robotic rehabilitation therapy in addition to routine rehabilitation training,while the control group was only given instructions for routine rehabilitation training.All the patients were assessed at the beginning of the training and at the end of 4,8 and 10 weeks of treatment.The Fugl-Meyer Assessment of lower extremities (FMA),range of motion (ROM) in hip and knee,force and tone of bilateral hip/knee flexors and extensors were used to evaluate stepping function before training,and after 4,8 and 10 weeks of treatment.Results There was no significant difference between the 2 groups with regard to FMA scores,the ROM in hip and knee,as well as force and tone of bilateral hip/ knee flexors and extensors (P ＞ 0.05).After treatment,the robotic group was significantly improved with all the evaluation indexes when compared to its baseline values (P ＜ 0.05).It was also shown that the robotic group improved to a significantly greater extent than the control group (P ＜ 0.05).Pearson's correlation analysis demonstrated a positive relationship between the ROM of knee or hip and lower limb function (P ＜ 0.05).Conclusions The Lokomat gait training rehabilitation robot can improve the lower extremities functions,as indicated by increase of ROM and muscle strength as well as decrease in muscle spasticity in hemiplegic patients after stroke.
