Abstract: 【Abstract】 Objective To investigate the clinical effect of orthopedic insoles combined with electromyography biofeedback on knee hyperextension in children with cerebral palsy. Method A total of 42 children with cerebral palsy and knee hyperextension who were treated in the Children's Hospital of Shanghai from June 2018 to June 2020 were selected as the research objects and randomly divided into study group (n=21) and control group (n=21). The children in the control group received conventional physical exercise therapy, while whom in the study group received orthopedic insole combined with lower limb electromyography biofeedback therapy on the basis of conventional therapy. The gross motor function measure(GMFM)-88 (zone D and zone E) scores, gait function (step length and step width), knee hyperextensionangle and improvement rate were compared between the two groups before and after treatment. Statistical analysis was performed by t-test, χ2 test or continuous-corrected χ2 test. Result During the 3-monthtreatment period, there were no adverse reactions such as muscle damage and joint pain in the two groups.Before treatment, there was no significant difference in GMFM (D zone and E zone) scores between the twogroups (all P>0.05). After 3 months of treatment, the scores of zone D in GMFM-88 in the study group weresignificantly higher than that in the control group [(32±3) vs (28±4) points, t=2.881, P=0.009)]; In GMFM-88, the scores of zone E in the study group were significantly higher than that in the control group [(23±5)and (20±6) points, t=2.134, P=0.046), the differences were statistically significant. Before treatment, therewas no significant difference in gait parameters (step length, step width) between the two groups (all P>0.05).After 3 months of treatment, the step length of the study group was significantly higher than that in the controlgroup [(24±3) vs (21±3) cm, t=2.378, P=0.032], the step width of the study group was better than that in thecontrol group [(8.1±0.8) vs (8.8±0.9) cm, t=2.183, P=0.037)], the differences between the two groups werestatistically significant. The improvement rate of knee hyperextension in the study group was 76.2% (16/21),which was significantly higher than that in the control group 19.0% (4/21), and the difference was statisticallysignificant (χ2=13.745, P=0.001). The knee hyperextension angle of the study group was significantly smallerthan that of the control group [(9±4) ° vs (12±3) °, t=2.908, P=0.008), the difference was statisticallysignificant. Conclusion Orthopedic insoles combined with electromyography biofeedback therapy caneffectively improve knee hyperextension in children with cerebral palsy, and can be used in clinical practice
