Abstract
Objective The objective of this study is to determine the effect of whole-body vibration (WBV) exercise on the anticipatory delay of core muscles in nonspecific low back pain (NSLBP) patients. Methods Forty participants with NSLBP were randomly divided into the WBV group and the control group. The sEMG signals of deltoid, erector spines (ES), multifidus (MF), rectus abdominis (RA), and transversus abdominus/internal oblique muscles (TrA/IO) were recorded before and after the intervention in the weight-shifting task. The relative activation time of each muscle was calculated. Results In the WBV group, the relative activation time of bilateral MF and bilateral TrA/IO was significantly reduced on shoulder flexion (right MF: P=0.014; left MF: P=0.011; right TrA/IO: P=0.008; left TrA/IO: P=0.026). As for shoulder abduction, except for the left TrA/IO and the left RA, the relative activation time of other muscles was significantly reduced (right ES: P=0.001; left ES: P < 0.001; right MF: P=0.001; left MF: P=0.009; right TrA/IO: P < 0.001; right RA: P=0.001). In the control group, there was no significant difference in the relative activation time of each muscle before and after the intervention (P > 0.05). Conclusions WBV exercise can effectively alleviate the anticipatory delay of core muscles in NSLBP patients, but the long-term effects still need further study. This trial is registered with ChiCTR-TRC-13003708.
Highlights
Nonspecific low back pain (NSLBP) is the most frequent form of low back pain. e proportion of NSLBP in low back pain accounts for up to 90% [1]
Because NSLBP has an unknown pathoanatomical cause, treatment concentrates on reducing pain and its consequences [2]. ere is plenty of evidence demonstrating that NSLBP prominently impacts on postural control [3,4,5], hypothesizing that altered postural control may overload the passive tissues of the spine, contributing to low back pain symptoms [2, 6]
At the baseline, when flexing the shoulder, the bilateral erector spinae (ES), bilateral MF, bilateral transversus abdominus/internal oblique (TrA/IO), and bilateral rectus abdominis (RA) in two groups are activated after the prime mover muscles. ere was no significant difference in the relative activation time of each muscle among two groups (P > 0.05) (Table 3)
