Evaluation Of The Effects Of Robot-assisted Gait Training On Walking Ability In Hemiplegic Patients By Three-dimensional Gait Analysis

Objective Hemiplegic gait is one of the main sequelae after stroke. It seriously affect the effects of rehabilitation therapy and the self-care ability. Walking ability is the focus and hotspot in the rehabilitation research.We all want to know if the effect of the robot-assisted gait training is better than that of traditional walking training, and we also want to know How to quantify the effects of the two groups. The study has an innovative use of the three-dimensional gait analysis, which is an advanced and objective assessment tool. We will explore effects of robot-assisted Gait Training on walking ability in hemiplegic patients according to all kinds of gait parameters.Methods Sixty hemiplegic patients were divided randomly into an experimental group and a control group with 30 in each. All of the 60 patients received traditional rehabilitation of drug therapy and physical therapy. The experimental group also received the robot-assisted gait training, while the control group received the traditional gait training. Sixty hemiplegic patients received these training 30 minutes per time,5 days per week, four weeks for one period of treatment, the study had two periods of treatment and 3 days between two periods. All patients received three-dimensional gait analysis before treatment and 8 weeks after training, we evaluated the analysis of time parameters,phase parameters, the joint Angle of lower limb, and the peak of the ground reaction force of two groups.Results It was found that the hemiplegic patients received robot-assisted gait training had significantly increased in walking velocity、stride length, cadence, significantly reduced in step width. The percentage of swing phase in paretic side increased, the percentage of stance phase in paretic side、the ratio of single support time and the percentage of double support phase decreased; Hip and knee joint angle increased, the peak number of vertical ground reaction force and forward one increased. Compared with the control group,the change was significant (P<0.05).Conclusions Compared with the traditional walking training, robot-assisted gait training can more effectively improve walking ability in hemiplegic patients.
