Effect Of Pelvic Assisted Rehabilitation Robot On The Gait Kinematics In Hemiplegic Patients After Stroke

Objective To explore the effect of pelvic assisted rehabilitation robot on gait kinematics in hemiplegia patients after stroke.Methods Forty stroke patients with hemiplegia were selected from the Second Hospital of Jiaxing City,Zhejiang Province,Rehabilitation Medicine Center Hospital in August 2016 to March 2017(Duration ≤ 6 months).They were randomly divided into treatment group(20 cases)and control group(20 cases).Both groups were treated with conventional neurological medications and traditional rehabilitation training.The control group was given routine walking function training.The treatment group was given pelvic assisted rehabilitation robot training on the basis of the control group.Treatment frequency of pelvic assisted rehabilitation robot is 20min/d,6d /week for 8 weeks.The two groups were assessed as follows before and after 8 weeks of treatment,including Fugl-Meyer asessment(FMA)the motor function(total score 34),the Berg balance scale(Berg Balance Scale,BBS),step pace,step length,pelvis rotation angle,pelvis roll angle,pelvis vertical movement distance,pelvis lateral movement distance.Results(1)The FMA scores of the lower extremities in the treatment group before treatment and after 8 weeks of treatment were(16.20 ± 4.85)scores and(21.40 ± 4.38)scores respectively,while those in the control group before and after 8 weeks of treatment were(16.95 ± 2.48)and(19.65 ± 2.98).There was significant difference in FMA score between the two groups after treatment for 8 weeks(P <0.05).(2)The BBS scores of the treatment group before treatment and after 8 weeks of treatment were(14.65±3.20)scores and(39.45±4.47)scores respectively,while those in the control group before and after 8 weeks of treatment were(15.75±5.13)and(35.90±5.33).There was significant difference in BBS score between the two groups after treatment for 8 weeks(P <0.05).(3)The step pace scores of the treatment group before treatment and after 8 weeks of treatment were(48.65±17.43)cm/s and(61.50±17.92)cm/s respectively,and the well side step length were(37.05±11.42)cm and(49.25±15.13)cm,the paretic step length were(35.00±10.18)cm and(48.65±11.49)cm,while those step pace in the control group before and after 8 weeks of treatment were(42.10±16.72)cm/s and(48.90±16.96)cm/s,and the well side step length were(33.90±10.46)cm and(41.10±9.11)cm,the paretic step length were(35.50±9.89)cm and(41.70±7.77)cm,There was significant difference in step pace scores,the well side step length score and the paretic step length between the two groups after treatment for 8 weeks(P <0.05).(4)The pelvis rotation angle scores of the treatment group before treatment and after 8 weeks of treatment were(14.67±2.91)degree and(9.93±1.92)degree respectively,and the pelvis roll angle were(25.41±3.53)degree and(15.57±1.68)degree,the pelvis vertical movement distance were(16.47±2.26)cm and(12.09±1.13)cm,the pelvis lateral movement distance were(11.96±3.46)cm and(8.92±3.26)cm,while those pelvis rotation angle scores of the control group before treatment and after 8 weeks of treatment were(13.30±1.62)degree and(10.49±0.64)degree respectively,and the pelvis roll angle were(26.14±2.94)degree and(18.34±1.72)degree,the pelvis vertical movement distance were(16.86±1.04)cm and(14.07±1.18)cm,the pelvis lateral movement distance were(11.80±2.57)cm and(9.49±2.70)cm,There was significant difference in the pelvis rotation angle,pelvis roll angle,pelvis vertical movement distance,pelvis lateral movement distance between the two groups after treatment for 8 weeks(P <0.05).(5)After 8 weeks of treatment,the FMA scores,BBS scores,step paces,well side step length,paretic step length,pelvis rotation angle,pelvis roll angle,pelvis vertical movement distance,pelvis lateral movement distance value Which was significantly higher than that in the control group(FMA scores,BBS scores,step paces,the well side step length,paretic step length,pelvis rotation angle,pelvis roll angle,pelvis vertical movement distance,pelvis lateral movement distance)(P <0.05).Conclusion(1)The pelvic assisted rehabilitation robots can improve pelvic control function of stroke hemiplegic patients.(2)The pelvis assisted rehabilitation robot can improve the walking and balance function of stroke hemiplegic patients.(3)The pelvis assisted rehabilitation robot can improve the lower limb motor function of stroke hemiplegic patients and make them return to their families and society better.
