背景。腰痛（LBP）几乎影响每个人一生中至少一次。各种荟萃分析显示，传统运动对减轻疼痛有很好的效果。然而，缺乏时间，尤其是对疼痛患者来说，害怕运动（“运动恐惧症”）以及功能限制往往反对参加这些活动。相比之下，新的训练技术，如全身肌电刺激（WB-EMS）的优势在于关节友好，时间有效，高度定制的训练方案，可能是LBP患者的另一种选择。个体患者数据的荟萃分析和WB-EMS与被动对照组的比较证实了证明原则。因此，本随机对照试验的目的是将WB-EMS与公认的背部强化运动方案进行比较，以确定对慢性非特异性腰痛患者的相应影响。方法和发现。这项随机、对照的多中心研究的重点是新颖的、时效性强的训练技术和LBP。在这篇文章中，重点主要放在WB-EMS与可比较的常规运动训练（CT）的比较上。110名40-70岁的非特异性慢性腰痛患者被随机分配到干预组（WB-EMS: 55对CT: 55）。两组都完成了专门针对LBP的为期12周的计划（WB-EMS: 1 x 20分钟/周vs. CT: 1 x 45分钟/周）。主动对照组的内容选择基于WB-EMS训练的原则，即在很短的时间内利用电刺激主要训练力量和稳定性。所有组的锻炼都是相似的，重点是加强和稳定躯干。结果测量通过四周疼痛日记（干预前和干预后四周）以及基线和干预12周后躯干肌肉的等距最大强度测量来评估。主要研究终点是腰椎的平均疼痛强度。次要研究终点是背部和腹部的最大等长强度。两组患者腰痛平均强度均显著降低(WB-EMS: -22.3 +/- 20.9% vs. CT: -30.2 +/- 43.9%
Background. Low back pain (LBP) affects almost everyone at least once in their lifetime. Various meta-analyses show promising effects on pain reduction for conventional exercise. However, the lack of time and, especially for pain patients, a fear of movement ("kinesiophobia") as well as functional limitations often oppose participation in such activities. In contrast, the advantage of novel training technologies like whole-body electromyostimulation (WB-EMS) lies particularly in a joint-friendly, time-effective, and highly customized training protocol and might be an alternative option for LBP patients. A meta-analysis of individual patient data and a comparison of WB-EMS against a passive control group confirmed the proof principle. Thus, the aim of this randomized controlled trial is to compare WB-EMS with a recognized back-strengthening exercise protocol to determine the corresponding effects on chronic, nonspecific LBP in people suffering from this. Methods and Findings. This randomized, controlled multicenter study is focused on novel and time-effective training technologies and LBP. In this contribution, the focus is primarily on the comparison of WB-EMS against a comparable conventional exercise training (CT). One hundred ten nonspecific chronic LBP patients, 40-70 years old, were randomly allocated to the intervention arms (WB-EMS: 55 vs. CT: 55). Both groups completed a 12-week program (WB-EMS: 1 x 20 min/week vs. CT: 1 x 45 min/week) specifically dedicated to LBP. The selection of the content of the active control group was based on the principles of WB-EMS training, which uses electrical stimulation to train mainly strength and stabilization in a very short time. Exercises were similar in all groups, with the focus on strengthening and stabilizing the trunk. Outcome measures were assessed by a four-week pain diary (before and during the last four weeks of intervention) as well as an isometric maximum strength measurement of the trunk muscles at baseline and after 12 weeks of intervention. Primary study endpoint was average pain intensity at the lumbar spine. Secondary study endpoints were maximum isometric strength of the back and the abdominals. The mean pain intensity of LBP decreased significantly in both groups (WB-EMS: -22.3 +/- 20.9% vs. CT: -30.2 +/- 43.9%; p
