The purpose of this study was to compare the effect of 2 exercise programs combined with electrotherapy on pain intensity and lumbar stabilizer muscles dimensions in patients with nonspecific chronic low back pain.
A randomized controlled clinical trial was performed with 41 patients with chronic LBP. Participants were randomly allocated into 2 groups: an experimental group (n = 20) received stabilization exercises plus electrotherapy, and a control group (n = 21) received routine exercises plus electrotherapy. Pain intensity, using a visual analog scale, and muscle dimensions of both right and left transverse abdominis and lumbar multifidus muscles, using rehabilitative ultrasonography, were assessed before and immediately after 4 weeks of intervention.
Significant improvement was identified after interventions on pain intensity and muscle size measurements in both groups (P < .01 in all instances). The only exception was the right-side lumbar multifidus cross-sectional area of the control group, which was not statistically significant (P = .081). No significant differences were found between the 2 exercise groups on pain intensity and muscle dimensions (P > .05 in all instances).
The results of this study suggest that a combination of electrotherapy with either routine or stabilization exercise programs may improve pain intensity and muscle dimensions in patients with nonspecific chronic low back pain.
本研究旨在比较两种运动方案联合电疗法对非特异性慢性下腰痛患者疼痛强度和腰椎稳定肌尺寸的影响。
对41例慢性下腰痛患者进行了一项随机对照临床试验。参与者被随机分为两组：实验组（n = 20）接受稳定化训练加电疗法，对照组（n = 21）接受常规训练加电疗法。在干预4周前和干预后立即，使用视觉模拟量表评估疼痛强度，并使用康复超声评估左右腹横肌和腰多裂肌的肌肉尺寸。
两组在干预后疼痛强度和肌肉尺寸测量均有显著改善（所有情况P <.01）。唯一的例外是对照组右侧腰多裂肌的横截面积，差异无统计学意义（P = 0.081）。两个运动组在疼痛强度和肌肉尺寸方面未发现显著差异（所有情况P>.05）。
本研究结果表明，电疗法与常规或稳定化运动方案相结合可能会改善非特异性慢性下腰痛患者的疼痛强度和肌肉尺寸。
