Vibration training is an adjuvant to muscle-strengthening exercises.
To investigate the short-term effects of direct vibration on the deep trunk muscles of patients with non-specific chronic low back pain (CLBP).
Participants with non-specific CLBP were randomly placed into two groups: the vibration-plus stabilization exercise (VSE) group (n= 31) and the conventional stabilization exercise (CSE) group (n= 31). The groups underwent 12 sessions of an exercise program. The thickness and activity of the trunk muscles were measured using ultrasonography and surface electromyography.
Ultrasonography revealed that the ratio of muscle thickness to contraction and relaxation was statistically increased after exercise in the bilateral transversus abdominis (TrA) and lumbar multifidus (LM) muscles in the CSE group (p= 0.031), and in the bilateral TrA, LM, and internal oblique (IO) muscles in the VSE group (p< 0.001). The LM/lumbar erector spinae (LES) ratio in the CSE group (p= 0.037), and the IO/rectus abdominis (RA), TrA/RA, and LM/LES ratios in the VSE group (p= 0.019) were statistically increased. Multiple regression analysis showed that symptom improvement was related to increased activity of the deep trunk muscles in the VSE group (p< 0.001).
Direct vibration can increase the selective activity of contracting deep trunk muscles.
振动训练是肌肉强化训练的一种辅助手段。
研究直接振动对非特异性慢性下腰痛（CLBP）患者深层躯干肌肉的短期影响。
将患有非特异性 CLBP 的参与者随机分为振动加稳定运动（VSE）组（n=31）和常规稳定运动（CSE）组（n=31）。两组均接受 12 次运动方案。使用超声和表面肌电图测量躯干肌肉的厚度和活动。
超声显示，CSE 组双侧腹横肌（TrA）和腰椎多裂肌（LM）的肌肉厚度与收缩和放松的比值在运动后统计学上增加（p=0.031），VSE 组双侧 TrA、LM 和内斜肌（IO）的肌肉厚度与收缩和放松的比值也增加（p<0.001）。CSE 组 LM/LES 比值（p=0.037），以及 VSE 组 IO/RA、TrA/RA 和 LM/LES 比值（p=0.019）均统计学增加。多元回归分析显示，症状改善与 VSE 组深层躯干肌肉活动增加有关（p<0.001）。
直接振动可以增加收缩深层躯干肌肉的选择性活动。
