Abstract

Introduction: About 10 million people have low back pain (LBP) disability in Brazil, and several therapies are used to treat this condition, such as kinesiotherapy, manual therapy (MT) and photobiomodulation-PBM. Although studies have investigated the use of these methods in LBP, research seeking to evaluate the efficacy of the association between techniques is still needed. Objective: To evaluate the activation of the muscles lumbar region with the influence of PBM and MT associated with kinesiotherapy in the treatment of LBP. Methods: Twenty individuals with chronic LBP were randomly divided into two groups. The first group (MT) received vertebral mobilization associated with a kinesiotherapy exercise program, while the second group (830nm-PBM) received PBM associated with the exercise program, twice a week for 8 weeks. It was performed an evaluation of pain perceived by the visual analogic scale (VAS), lumbar disability by the Oswestry questionnaire, muscle strength by strain gauge and activation through surface electromyography, before and after the treatment protocol. EMG data analysis was performed by MatLab® software. The ANOVA two-way test was used (degree of significance p≤0.05), and the effects size by Hedge test. Results: Considering pain, the two groups presented a significant result (p<0.05). In muscle activation only the multifidus obtained different during side bridge (p<0.05) when compared intragroups. But none of the variables were different when evaluating intergroups. Conclusion: Both MT and PBM associated with kinesiotherapy for 8 weeks are effective in reducing pain, improving motor control and stability of the lumbar spine in patients with chronic LBP.
腰部肌肉激活区的肌电图比较手法治疗和运动疗法相关的光生物调制对腰痛患者的影响
简介:巴西约有1000万人患有腰痛(LBP)残疾,有几种治疗方法用于治疗这种疾病,如运动疗法、手工疗法(MT)和光生物调节- pbm。尽管已经有研究调查了这些方法在腰痛中的应用,但仍需要评估这些技术之间关联的有效性的研究。目的:探讨运动疗法联合PBM和MT治疗腰痛时腰区肌肉激活的影响。方法:20例慢性腰痛患者随机分为两组。第一组(MT)接受与运动疗法运动计划相关的椎体活动,而第二组(830nm-PBM)接受与运动计划相关的PBM,每周两次,持续8周。采用视觉模拟量表(VAS)评估疼痛感,Oswestry问卷评估腰椎失能,应变计评估肌肉力量,表面肌电图评估激活度。肌电数据分析采用MatLab®软件。采用方差分析双向检验(显著性p≤0.05),效应量采用Hedge检验。结果:考虑疼痛,两组疗效显著(p<0.05)。在肌活动方面,仅多裂肌在侧桥期间与组内比较有差异(p<0.05)。但在评估群体间时,没有任何变量是不同的。结论:MT和PBM联合运动疗法8周可有效减轻慢性腰痛患者的疼痛,改善运动控制和腰椎稳定性。
