肌电生物反馈治疗痉挛型脑性瘫痪患儿尖足的效果

Effect of Electromyographic Biofeedback on Pointed Foot in Children with Spastic Cerebral Palsy

目的探讨肌电生物反馈技术治疗痉挛型脑瘫患儿尖足的临床疗效。方法 2014年6月-2015年12月,本院80例痉挛型脑瘫尖足患儿,分为常规治疗组（n=40）和肌电生物反馈组（n=80）。常规治疗组接受运动疗法结合推拿治疗,肌电生物反馈组加用生物反馈治疗。比较治疗前及治疗8周后踝关节被动背屈角度（PROM）、表面肌电评价结果和选择性控制评定结果。结果治疗后,两组患儿踝关节PROM较治疗前显著减小（t〉9.142,P〈0.001）,胫前肌积分肌电值（i EMG）、均方根值（RMS）及踝关节选择性运动控制评分均较治疗前明显增大（t〉3.456,Z〉3.178,P〈0.01）;且肌电生物反馈组均明显优于常规治疗组（t〉3.737,Z=-2.748,P〈0.01）。结论肌电生物反馈治疗能更好改善痉挛型脑瘫患儿足背曲,改善其尖足步态。

Objective To explore the clinical curative effect of electromyographic biofeedback on pointed foot in children with spastic cerebral palsy. Methods From June, 2014 to December, 2015, 80 children with spastic cerebral palsy and pointed foot were divided into conventional group（n=40） and electromyographic biofeedback group（n=40）. The conventional group received exercise and massage, while the electromyographic biofeedback group received electromyographic biofeedback in addition. The passive range of motion（PROM） of ankle,the surface electromyographic results and the selective control results were compared before and eight weeks after treatment. Results After treatment, the PROM significantly decreased in both groups（t〉9.142, P〈0.001）; the integrated electromyography and root mean square, and the selective control increased in both groups（t〉3.456, Z〉3.178, P〈0.01）, which were better in the electromyographic biofeedback group than in the conventional group（t〉3.737, Z=-2.748, P〈0.01）. Conclusion Electromyographic biofeedback can further improve the foot dorsal flexure and pointed foot gait of spastic cerebral palsy children.
