高频超声检测偏瘫继发肩-手综合征患者正中神经的临床应用

Clinical application of high-frequency ultrasonography in the detection of median nerve of hemiplegia-secondary shoulder-hand syndrome patients

目的 :探讨高频超声在偏瘫继发肩-手综合征患者正中神经检测中的临床应用价值。方法 :对50例偏瘫继发肩-手综合征患者健、患侧上臂及腕管正中神经的前后径和横截面积进行测量,并与临床分期和患侧肌力影响因素进行对照研究。结果:患者患侧正中神经的前后径和横截面积随着肩-手综合征临床分期加重变窄、缩小明显。随着患侧肌力恢复,正中神经直径及横截面积变大,差异有统计学意义(P<0.05)。结论:高频超声能清晰显示偏瘫继发肩-手综合征患者的正中神经,并检测到正中神经在形态学上的变化,可评价康复治疗的效果。

Objective：To investigate the clinical application of high-frequency ultrasonography in the detection of median nerve of hemiplegia-secondary shoulder-hand syndrome patients. Methods：The anteroposterior diameter and cross-sectional area of me-dian nerve in the upper arm and carpal tunnel of healthy and affected side of 50 hemiplegia-secondary shoulder-hand patients were measured,and the clinical stages and muscle strength were analyzed comparatively. Results：As shoulder-hand syndrome clinical stage increased significantly ,the anteroposterior diameter and cross-sectional area of median nerve in the affected side of patients became narrow obviously;with the muscle strength of the affected side recovered,the median nerve diameter and cross-sectional area increased,but not obviously. The difference was statistically significant （P〈0.05）. Conclusions：High-fre-quency ultrasound can clearly display the median nerve of hemiplegia-secondary shoulder-hand syndrome patients,can detect the morphological changes of median nerve,and can provide a reliable basis for the evaluation of rehabilitation effect.
