Effects of lumbar-pelvic training combined with electroacupuncture on chronic nonspecific low back pain

Abstract

This observational study was conducted to investigate the effect of lumbar-pelvic training (LP) combined with electroacupuncture (EA) in the treatment of chronic nonspecific low back pain. One hundred and twenty patients diagnosed with chronic nonspecific low back pain were evenly randomized to receive the following 4 treatments for 2 weeks: LP combined with EA (Group A), EA (Group B), LP (Group C) or no intervention (Group D). The LP was a self-developed training program containing 5 movements and was conducted three times a week to build up the strength of abdomen muscle groups. Four acupoints along the foot-taiyang bladder meridian and the governor vessel were chosen for EA five times a week based on the theory of Traditional Chinese Medicine. The Visual Analog Scale and Oswestry Disability Index were measured before and after treatment to assess the reduction of pain intensity and functional disability, respectively. Following the treatments, Visual Analog Scale and Oswestry Disability Index scores in all 3 intervention groups were significantly lower than those in the Group D without intervention (P < .01). Among the intervention groups, Group A's scores were lower than those of Group B or Group C (P < .01). The overall efficacy of Group A was 93.33%, which was higher than that of Group B (76.67%) and Group C (70.00%) (P < .01). In conclusion, this study suggest that our self-developed lumbar-pelvic training combined with electroacupuncture is effective for chronic nonspecific low back pain in terms of pain and disability reduction.
