康复机器人训练对偏瘫儿童腹肌厚度和平衡能力的效果OA

Objective To observe the effect of rehabilitation robot training on abdominal muscles thickness and balance ability in children with hemiplegia. Methods From October,2024 to December,2025,58 children with hemiplegia were admitted to Beijing Bo'ai Hospital and randomly divided into control group(n=29)and experimental group(n=29).Both groups received conven-tional rehabilitation treatment,and the experimental group received rehabilitation robot training in addition,for four weeks.The thickness of bilateral external oblique,internal oblique and transversus abdominis,Berg Balance Scale(BBS)score,the time of Timed Up and Go Test(TUGT),the center of pressure(COP)ellipse area,and self-selected walking speed(SWS)and maximum walking speed(MWS)of 10-meter walk test were compared before and after training. Results Three cases dropped out in each group.After training,the thickness of the external oblique,internal oblique and transverse abdominis on the hemiplegic side increased significantly in the experimental group(|t|>7.280,P<0.001,Cohen's d=1.43～2.01),and was better in the experimental group than in the control group(|t|>2.895,P<0.01,Cohen's d=0.80～1.60);the BBS score increased in both groups(|t|>6.667,P<0.001,Cohen's d=1.30～4.06),and was better in the experimental group than in the control group(t=-2.721,P<0.01,Cohen's d=0.75).The time of TUGT decreased in both groups(t>5.790,P<0.001,Cohen's d=1.14～2.68),and was better in the experimental group than in the control group(t=2.290,P<0.05,Cohen's d=0.63).The SWS and MWS increased in both groups(|Z|>2.910,P<0.01,r=0.40～0.68),and were better in the experimental group than in the control group(|Z|>2.912,P<0.05,r=0.40～0.45),and the differences remained significant after correction. Conclusion Rehabilitation robot training can improve the thickness of external oblique,the internal oblique and transver-sus abdominis muscles on the hemiplegic side in children with hemiplegia,and improve their balance and walk-ing functions.
