INTRODUCTION:
According to the Global Burden of Disease Study (GBD), the global prevalence and incidence of LBP are increasing year by year, and it has become a public health problem.CNLBP (Chronic non-specific low back pain, CNLBP), as a common chronic pain syndrome, usually lacks a clear pathological or imaging diagnosis, and manifests itself as a persistent low back and hip pain lasting more than three months. Studies have shown that the prevalence of CNLBP is as high as 28%, and it has a profound impact on the physical, psychological and social functioning of individuals. In recent years, exercise therapy (ET) applied to CNLBP group rehabilitation treatment research is becoming more and more extensive, scholars have recommended the addition of exercise therapy as a first-line non-pharmacological tool to conventional treatment.
Based on the “The stabilizing system of the spine”,“Joint by Joint Approach”, and “Biopsychosocial Model”, analyzed the common and different effects of line dance exercise and physical flexibility training on CNLBP from the physiological, psychological, and social factors. From individual physical function changes, internal emotional and behavioral changes, and external social relationship adjustments, to develop a comprehensive and improved efficacy of CNLBP in a multidimensional manner, and to provide a new direction for the training program for patients with CLBP.
METHODS:
Sixty CNLBP college students were randomized to receive 12 weeks of line dance (with Baduanjin) or physical flexibility training. Using multiple methods (eg, experimental method, questionnaire survey method, mathematical and statistical method) were used to test the indicators of physiological and psychological dimensions, of which the physiological indicators included: balance (static, dynamic), lumbar flexibility (ROM); the psychological indicators included: pain index (VAS), assess the disability (RMDQ), fear of beliefs (FABQ), Positive and Negative affect (PANAS), psychological flexibility (AAQ-Ⅱ), social support (SSRS). Finally, through the 12-week intervention, further explore the data changes of line dance exercise and physical flexibility training on CNLBP, and provide theoretical references for subsequent studies.
RESULTS:
After 12 weeks of intervention in two ways, the balance ability、ROM、 VAS 、PANAS、 FABQ, and RMDQ scores of the two groups were significantly improvement compared with the pre-intervention period (p < 0.01), AAQ-Ⅱ and SSRS scores were reduced(p < 0.05).
CONCLUSION:
Line dance and physical flexibility training are both effective methods for treating CNLBP, and improving subjects daily behavioral performance, emotional state, and social interaction. Further in terms of the comparison between the two, the improvement effect is as follows: Physical flexibility training group: balance ability, lumbar flexibility ("flexion", "extension"); Line dance group: lumbar flexibility ("left flexion", "right flexion"), PANAS, SSRS; no difference: VAS, RMDQ, FABQ, AAQ-Ⅱ.
