Core stability training targeting multifidus: monitor using ultrasound combined with surface electromyogram versus no monitor

Abstract

Abstract:

BACKGROUND: Core stability training has been shown to improve local core muscles. But whether the core stability training monitored by ultrasound imaging combined with surface electromyogram can treat low back pain better remains unclear.
OBJECTIVE: To investigate the influence of multifidus thickness contraction ratio and electromyogram signal characteristics before and after core stability training monitored using ultrasound imaging combined with surface electromyogram, compared with the same training without monitor.
METHODS: Fifty healthy volunteers were randomly allocated into monitor group (n=26) and control group (n=24), and then underwent core stability training monitored using ultrasound imaging combined with surface electromyogram and without monitor, respectively. The multifidus thickness contraction ratio value and surface electromyogram signal value before and after 4 and 8 weeks of training were compared.
RESULTS AND CONCLUSION: Before training, there were no significant differences in the thickness contraction ratio value and average amplitude of electromyogram of multifidus between two groups (P > 0.05). After 8 weeks of training, the thickness contraction ratio value and average amplitude of electromyogram value of multifidus in both groups especially the monitor group were significantly higher than those before training (P < 0.05). In summary, the core stability training using ultrasound imaging combined with surface electromyogram can obviously increase multifidus thickness contraction ratio and average surface electromyogram value in healthy human. Meanwhile, the effect of monitoring training is greater than the same training without monitor, which provides evidence for low back pain patients undergoing core stability training.
