改良PNF技术对脑卒中偏瘫患者下肢功能的影响

摘要

目的：观察改良本体感觉神经肌肉促进技术（PNF）对脑卒中偏瘫合并踝阵挛患者下肢功能的治疗作用。方法：将脑卒中偏瘫合并踝阵挛患者40例随机分为观察组和对照组各20例。对照组患者采用常规 PN F技术治疗，观察组患者应用改良PN F技术，即主要利用对踝关节牵伸、背伸和外翻肌群的主动力量的训练，加强患者的主动踝背伸和外翻，加强胫前肌、腓骨长短肌力量，从而有效改变踝阵挛。结果：训练20d后，2组患者综合痉挛量表（CSS）、下肢Fugl‐Meyer评定（FMA）、Berg平衡功能评分（BBS）及10m最大步行速度（10m MWS）均较治疗前有明显好转（P＜0．05），观察组各项评分改善幅度更高于对照组（P＜0．05）。结论：改良下肢PNF技术能更有效地提高偏瘫恢复前期踝阵挛的控制，促进下肢运动分离，提高步行能力及速度，适用于国内脑卒中患者踝阵挛的痉挛治疗。%Objective:To investigate the therapeutic effectiveness of improved PNF technique on hemiplegic patient with ankle clonus .Method:Forty patients with ankle clonus were randomly divided into observation group and con‐trol group (n=20 each) .The observation group received improved PNF technique ,which has ability to effectively improve the spasm of the hemiplegic patient with ankle clonus by strengthening the strength of tibialis anterior mus‐cle .The control group received routine PNF technique .Results:Twenty days after treatment ,CSS ,FMA of lower limbs ,Berg at baseline and the speed of walk in ten metres in both two groups were significantly higher than those before treatment (P<0 .05) ,more significantly in the observation group than in the control group (P<0 .05) .Con‐clusion:The improved PNF technique can significantly improve the ankle clonus of previous rehabilitation ,promote separation of movement on lower limbs ,and heighten the speed and ability of walk .The improved PNF technique is applied to treat the hemiplegic patients with ankle clonus .
