Objective To observe the clinical efficacy and unveil the mechanism of thunder-fire moxibustion plus hydrokinesitherapy in treating nonspecific low back pain(NLBP)based on the post-treatment change in the cross-sectional area of paravertebral muscles using lumbar magnetic resonance imaging.Method A total of 120 NLBP patients were randomized into a trial group and a control group,with 60 cases in each group.The trial group was treated with thunder-fire moxibustion and hydrokinesitherapy,and the control group received hydrokinesitherapy alone.Before and after the treatment,the Roland-Morris dysfunction questionnaire(RMDQ)score,Oswestry disability index(ODI)score,and the ratio of each paravertebral muscle(erector spinae muscle,multifidus muscle,and psoas major muscle)cross-sectional area to the vertebral body area were observed.The clinical efficacy was compared between the two groups.Result After the treatment,both groups showed a decrease in the RMDQ and ODI scores and an increase in the ratio of each paravertebral muscle cross-sectional area to the vertebral body area,all showing statistical significance(P＜0.05).After the intervention,the trial group had lower RMDQ and ODI scores and higher ratios of paravertebral muscle cross-sectional area to the vertebral body area compared with the control group,presenting statistical significance(P＜0.05).The total effective rate was 91.2%in the trial group,notably higher than 80.4%in the control group,and the between-group difference was statistically significant(P＜0.05).Conclusion Thunder-fire moxibus-tion plus hydrokinesitherapy can produce valid efficacy in treating NLBP.This method can increase the cross-sectional area of the erector spinae,multifidus,and psoas major muscles,improve paravertebral muscle atrophy,reduce pain,and enhance the quality of life of the patients.
