摘要
目的研究实时超声反馈下,腹横肌激活训练对稳定性不足亚型慢性腰痛患者不同体位功能动作中腹横肌激活程度的影响。方法将19例稳定性不足亚型慢性腰痛患者随机分为言语指导组(9例)和超声反馈组(10例),分别予以言语指导和超声反馈下的腹横肌激活训练。比较干预前后仰卧位和站立位功能动作中腹横肌厚度变化率。结果言语指导组在干预后仰卧位髋外旋、直腿抬高和站立位各功能动作中腹横肌厚度变化率较干预前显著增加(P<0.05),仰卧位屈髋屈膝动作中腹横肌厚度变化率显著增加(P<0.01);超声反馈组在干预后仰卧位和站立位各功能动作中腹横肌厚度变化率较干预前显著增加(P<0.01);但两组间差异无统计学意义(P>0.05)。结论超声影像能够有效地评估慢性腰痛患者在仰卧位和站立位功能动作下的腹横肌厚度变化情况;超声影像可以为腰痛患者学习腹横肌激活动作提供实时动态的视觉反馈,但腹横肌激活训练中加入实时超声反馈与言语指导相比不能增加腹横肌激活程度。
Objective To investigate the effects of abdominal drawing-in maneuver with real-time ultrasound biofeedback on transversus abdominis activation level during functional tasks in different positions in patients of chronic low back pain with stabilization-deficit. Methods Nineteen patients of chronic low back pain with stabilization-deficit were randomly divided into verbal instruction group(n=9) and ultrasound biofeedback group(n=10), and received abdominal drawing-in maneuver with verbal instruction and ultrasound biofeedback respectively. Percentage changes of transversus abdominis thickness during supine and upright loaded tasks were compared before and after intervention. Results After intervention, percentage changes of transversus abdominis thickness increased significantly in verbal instruction group during supinehip external rotation, straight leg raising and upright loaded functional tasks (P<0.05), and percentage changes of transversus abdominis thickness during supine hip and knee flexion demonstrated great increases(P<0.01). After intervention, percentage changes of transversus abdominis thickness demonstrated great increases in ultrasound biofeedback group during all functional tasks(P<0.01). No differences were observed between the two groups(P>0.05). Conclusions Ultrasound image could effectively assess the thickness changes of transversus abdominis in patients with chronic low back pain during supine and upright loaded functional tasks. Ultrasound image could provide chronic low back pain patients with real-time and dynamic visual feedback. However, compared with verbal instruction, adding real-time ultrasound biofeedback to abdominal drawing-in maneuver does not further increase the transversus abdominis activation level.
