Objective:The aim of this study is to evaluate the therapeutic efficacy and clinical implications of utilizing lower limb rehabilitation robots in the rehabilitation process for patients with stroke-induced hemiplegia.Methods:40 stroke hemiplegia patients with lower limb muscle strength≤2 were selected and randomly divided into an observation group(20 cases)and a control group(20 cases).The control group received physical therapist-administered exercise therapy,which was divided into two training stages:passive and active exercises,combined with various conventional rehabilitation treatments.The observation group received passive training with a rehabilitation robot in the first stage,and in the second stage,they underwent active exercise training administered by a physical therapist combined with passive and assisted exercise training using the rehabilitation robot.The conventional rehabilitation treatment was the same for both groups.The evaluation indicators included comfort evaluation,Fugl-Meyer Assessment of Motor Function(FMAS),Modified Ashworth Scale(MAS),and Modified Barthel Index(MBI).Results:After the first phase,the evaluation of patient comfort revealed significantly higher scores in the observation group compared to the control group,yielding a statistically significant difference(t=1.439,P<0.05).Following training,both groups exhibited significantly elevated scores on the Fugl-Meyer Assessment of Motor Function(FMAS)compared to their pre-training levels(t=-6.722,t=-8.732,P<0.05),yet no significant difference was noted between the two groups(P>0.05).Following the second phase,the post-training FMAS scores in both the observation and control groups were significantly higher than their respective pre-training scores(t=-24.491,t=-8.947,P<0.05),with the observation group demonstrating a statistically significant increase over the control group(t=-0.775,P<0.05).Additionally,the Modified Ashworth Scale(MAS)grading for spasticity in the observation group was superior to that of the control group,indicating a statistically significant difference(P<0.05).Both groups exhibited higher scores on the Modified Barthel Index(MBI)after training compared to their pre-training levels(t=-1.430,t=-1.651,P<0.05),though no significant intergroup difference was observed(P>0.05).Conclusion:In the treatment stage dominated by passive exercises,rehabilitation robots can achieve equivalent therapeutic effects as therapists through precise control and standardized operations.However,when combined with the comprehensive treatment administered by therapists,the therapeutic effects can be further optimized,and the degree of muscle spasms can be reduced.
