BACKGROUND
Whole body vibration (WBV) training as an intervention method can cure chronic low back pain (CLBP). Different WBV parameters exert different effects on lumbar-abdominal muscle performance. Currently, there is a lack of study researched the influence of WBV training on patients with CLBP by lumbar-abdominal muscle activity. Therefore, this study aimed to investigate how WBV and exercise and their interactions influence lumbar-abdominal muscle activity in patients with CLBP.
METHODS
a group of ambulatory patients with chronic low back pain. Muscle activities of the multifidus (MF), erector spinae (ES), abdominal oblique externus muscle (AOE) and the rectus abdominis muscle (RA) were measured by surface electromyography, whereas participants performed 4 different exercises (single bridge, plank, side stay and V crunch) during three whole body vibration conditions and a no-vibration condition in a single experimental session.
RESULTS
Compared with the same exercises without whole body vibration, muscle activity increased when whole body vibration was added to the exercises. MF; the WBV frequency (P = 0.002,) and exercise (P < 0.001) presented significant effects on the root mean square of MF, whereas exercise * frequency (P = 0.044) also resulted in significant interaction effects. ES: the significant differences were detected at WBV frequency (P < 0.001), exercise (P < 0.001), the interaction effect of exercise and frequency (P = 0.225) was no significant. RA: the significant difference was detected at WBV frequency (P = 0.018), the effect of exercise (P = 0.590) and the exercise * frequency interaction (P = 0.572) were no significant. AOE: the significant difference was detected at WBV frequency (P < 0.001), the effect of exercise (P = 0.152) and the exercise * frequency interaction (P = 0.380) were no significant.
CONCLUSION
Adding whole body vibration to exercise could increase muscle activation of lumbar-abdominal muscle in patients with CLBP. The optimum frequency for lumbar-abdominal muscles is 15 Hz. The best exercises include plank for multifidus and erector spinae, V crunch for rectus abdominis and single bridge for abdominal oblique externus.

背景
全身振动（WBV）训练作为一种干预方法可治疗慢性下腰痛（CLBP）。不同的WBV参数对腰腹肌性能产生不同影响。目前，缺乏关于WBV训练对CLBP患者腰腹肌活动影响的研究。因此，本研究旨在探讨WBV与运动及其相互作用如何影响CLBP患者的腰腹肌活动。
方法
一组慢性下腰痛的门诊患者。通过表面肌电图测量多裂肌（MF）、竖脊肌（ES）、腹外斜肌（AOE）和腹直肌（RA）的肌肉活动，而参与者在单次实验中于三种全身振动条件和一种无振动条件下进行4种不同运动（单桥运动、平板支撑、侧支撑和V型卷腹）。
结果
与无全身振动的相同运动相比，运动中加入全身振动时肌肉活动增加。MF：WBV频率（P = 0.002）和运动（P < 0.001）对MF的均方根有显著影响，而运动频率（P = 0.044）也产生显著交互作用。ES：在WBV频率（P < 0.001）、运动（P < 0.001）时检测到显著差异，运动和频率的交互作用（P = 0.225）不显著。RA：在WBV频率（P = 0.018）时检测到显著差异，运动的影响（P = 0.590）和运动频率交互作用（P = 0.572）不显著。AOE：在WBV频率（P < 0.001）时检测到显著差异，运动的影响（P = 0.152）和运动*频率交互作用（P = 0.380）不显著。
结论
运动中加入全身振动可增加CLBP患者腰腹肌的肌肉激活。腰腹肌的最佳频率为15Hz。最佳运动包括针对多裂肌和竖脊肌的平板支撑、针对腹直肌的V型卷腹以及针对腹外斜肌的单桥运动。
