Low back pain (LBP) is a high impact condition that affects the working population, generating social and economic repercussions, the most relevant symptoms being pain and functional disability. Conservative treatment is often based on stabilizing spinal muscles with exercises: the Russian current (RC) is reported as an alternative, because it promotes muscle contraction, providing muscle strengthening and hypertrophy.
To assess the effectiveness of the RC in aiding the treatment of low back pain.
This randomized study included 23 women aged 18-30 years, divided into two groups: the control group (CG) and the Russian current group (RCG), for four weeks. Pain (visual analogue scale, VAS; pressure algometer, PA), function (Oswestry Low Back Disability Index), resistance (trunk resistance [TR] test) and thickness changes in the muscle (ultrasound image) were evaluated before and after the RC protocol and at one-month follow-up.
There were significant VAS reductions in both groups, but at follow-up these had only been maintained in the RCG, which presented lower values than the CG in the second evaluation. For PA, Oswestry and TR, there were differences only in the RCG. In a comparison of LBP between the groups, the initial difference disappeared in subsequent evaluations; TR presented higher values in evaluation 2 and 3 in the RCG group. In terms of thickness changes, differences between the groups were reduced after treatment.
The proposed treatment was effective in the reduction of LBP, with short-term improvement in resistance and thickness changes of the multifidus.
腰痛（LBP）是一种对劳动人口有重大影响的疾病，会产生社会和经济影响，最相关的症状是疼痛和功能障碍。保守治疗通常基于通过锻炼来稳定脊柱肌肉：俄罗斯电流疗法（RC）被报道为一种替代方法，因为它能促进肌肉收缩，增强肌肉力量并使其肥大。
评估俄罗斯电流疗法在辅助治疗腰痛方面的有效性。
这项随机研究纳入了23名年龄在18至30岁之间的女性，分为两组：对照组（CG）和俄罗斯电流疗法组（RCG），为期四周。在俄罗斯电流疗法方案前后以及随访一个月时，评估疼痛（视觉模拟量表，VAS；压力痛觉计，PA）、功能（Oswestry腰痛残疾指数）、阻力（躯干阻力[TR]测试）和肌肉厚度变化（超声图像）。
两组的VAS均有显著降低，但在随访时，只有RCG组维持了这种降低，在第二次评估中其VAS值低于CG组。对于PA、Oswestry和TR，只有RCG组存在差异。在两组之间的腰痛比较中，最初的差异在后续评估中消失；在RCG组的评估2和评估3中，TR值更高。在厚度变化方面，治疗后两组之间的差异减小。
所提出的治疗方法在减轻腰痛方面有效，能在短期内改善多裂肌的阻力和厚度变化。
