实时超声成像生物反馈脊柱稳定训练对慢性腰肌劳损病人的影响

目的 探讨实时超声成像（RUSI）生物反馈脊柱稳定训练对慢性腰肌劳损（chronic lumbar muscle strain,CLMS）病人的影响。方法 选择2019年1月至2020年6月在中国人民解放军联勤保障部队第九一〇医院就诊的74例CLMS病人作为研究对象，采用随机数字表法将病人分为对照组和观察组各37例。观察组给予RUSI生物反馈脊柱稳定训练，对照组给予脊柱稳定训练。于治疗前后观察病人多裂肌厚度静息时（T0）、收缩10 s(T1)、收缩20 s(T2)、收缩30 s(T3)]、疼痛视觉模拟评分（VAS）、功能障碍指数（ODI）和生活质量（SF-12 MCS和SF-12PCS）。结果 干预后两组病人T1、T2、T3时的多裂肌厚度均高于干预前（P<0.05），且干预后观察组T1(27.93±2.60)比（25.35±2.14）mm]、T2(27.11±2.13)比（24.89±1.89）mm]、T3(24.36±2.86)比（26.85±2.93）mm]时的多裂肌厚度高于对照组（P<0.05）。干预6周后两组病人VAS和ODI均较干预前显著降低（P<0...

Effect of real-time ultrasound imaging biofeedback spinal stabilization training on patients with chronic lumbar muscle strain

Objective To study the effect of real-time ultrasound imaging (RUSI) biofeedback spinal stability training on patients with chronic lumbar muscle strain (CLMS).Methods Seventy four patients with CLMS treated in The 910th Hospital of the Joint Lo-gistics Support Force of the PLA of China from January 2019 to June 2020 were selected as the study subjects. The patients were ran-domly assigned into control group and observation group, with 37 patients in each group. The observation group was given RUSI bio-feedback spinal stability training, and the control group was given spinal stability training. The thickness of the multifidus muscle rest-ing (T0), contraction for 10 s (T1), contraction for 20 s (T2), contraction for 30 s (T3)], visual analog score (VAS), oswestry dysfunctionindex (ODI) and quality of life (SF-12 MCS and SF-12 PCS) were observed before and after treatment.Results After intervention, the thickness of multifidus muscle at T1, T2 and T3 in the two groups were higher than that before the intervention (P<0.05), and the thick- ness of multifidus muscle at T1 (27.93±2.60) vs. (25.35±2.14) mm], T2 (27.11±2.13) vs. (24.89±1.89) mm] and T3 (24.36±2.86) vs. (26.85±2.93) mm] in observation group were higher than those in control group (P<0.05). After intervention, VAS and ODI in two groups were significantly lower than those before intervention (P<0.05), and VAS (2.67±0.54) vs. (3.36±0.73) scores] and ODI (14.32± 4.97)% vs. (21.05±5.42)%] in the observation group were lower than those in the control group (P<0.05). After intervention, PCS and MCS in two groups were significantly higher than those before intervention (P<0.05), and MCS (39.02±4.28) vs. (35.87±4.39) scores] and PCS (43.05±9.82) vs. (37.08±3.25) scores] in observation group were higher than those in control group (P<0.05). Conclusion RUSI biofeedback spinal stability training is helpful to improve the multifractal and contractile performance, reduce the degree of pain,reduce the degree of dysfunction and improve the quality of life of patients with CLMS.
