镜像神经元视觉反馈疗法结合语音矫治对脑卒中构音障碍的治疗效果

Clinical efficacy of mirror visual feedback therapy combined with speech correction in patients with dysarthria after stroke

目的观察镜像神经元视觉反馈疗法结合语音矫治对脑卒中后构音障碍的康复作用。方法 80例脑卒中后伴构音障碍患者随机均分为观察组和对照组。对照组仅给予语音矫治,观察组在语音矫治的基础上再给予镜像神经元视觉反馈疗法。比较两组治疗前和治疗3周后最长发声时间(MPT)、改良Frenchay构音障碍评估量表(FDA)评分、嗓音障碍指数量表(VHI)评分以及临床疗效。结果与治疗前相比,两组治疗后MPT增加(P<0.05),改良FDA评分和VHI评分降低(P<0.05),其中观察组治疗后MPT、改良FDA评分和VHI评分改善更加明显(P<0.05)。观察组治疗显效率和总有效率均高于对照组(42.5%vs.5.0%和92.5%vs.52.5%)(P<0.05)。结论镜像神经元视觉反馈疗法结合语音矫治可以改善脑卒中后构音障碍患者的口舌运动,提高其沟通交流能力和生活质量。

Objective To investigate the clinical efficacy of mirror visual feedback therapy combined with speech correction in the patients with dysarthria after stroke.Methods A total of 80 patients with dysarthria after stroke were equally randomized into two groups of A and B.The patients in group A only recerived speech correction, while the patients in group B accepted mirror visual feedback therapy on the basis of speech correction.The maximum phonation time(MPT),modified Frenchay dysarthria assessment(FDA) score, voice handicap index(VHI) and clinical outcomes were recorded before and three weeks after treatment in both groups.Results Compared with before, the MPT was increased and the scores of modified FDA and VHI were decreased in both groups after treatment(P<0.05),which were improved more obviously in group B than those in group A(P<0.05).The markedly effective rate and total effective rate in group B were higher than those in group A(42.5% vs.5.0% and 92.5% vs.52.5%)(P<0.05).Conclusion Mirror visual feedback therapy combined with speech correction may improve tongue movement, communication ability and life quality in the patients with dysarthria after stroke.
