Effects of Fu's subcutaneous needling on clinical efficacy and psychological cognitive characteristics in patients with chronic non-specific low back pain: a randomized controlled trial.

ABSTRACT

BACKGROUNDAND PURPOSE: Low back pain (LBP) is a major global public health problem. Evidence shows that LBP is also related to cognitive, psychological, and lifestyle factors. Fu's subcutaneous needling (FSN) has been used for the treatment of musculoskeletal problems for many years. This prospective randomized controlled trial aimed to evaluate the clinical efficacy and fear avoidance beliefs of FSN in the treatment of patients with chronic non-specific LBP. MATERIAL AND METHODS: Ninety participants with chronic non-specific LBP were randomly divided into the FSN and the traditional acupuncture (TA) groups (n = 45) and received either FSN or TA treatment for three consecutive days from December 2021 to March 2023. The primary outcome was pain intensity measured by the visual analogue scale (VAS). Secondary outcomes were trunk extensor endurance (TEE), lumbar range of motion (ROM), and the Fear Avoidance Beliefs Questionnaire (FABQ). Outcome measurements were made before the first treatment and after each treatment. Follow-up assessments of VAS and FABQ scores were conducted one month after treatment. RESULTS: The FSN group had significantly lower VAS and FABQ scores at each time point after intervention compared to the TA group (P < 0.01). The scores of TEE and lumbar ROM were higher in the FSN group than those in the TA group (P < 0.01). Repeated measures analysis of variance (ANOVA) showed significant time effects, group effects, and interaction effects for VAS, TEE, lumbar ROM, and FABQ in both groups (P<0.01). One month after treatment, the FSN group had significantly lower VAS and FABQ scores compared to the TA group (P<0.05). CONCLUSION: This study suggested that FSN was superior to TA in terms of clinical efficacy and fear-avoidance beliefs in the treatment of chronic non-specific LBP. FSN could be used as an effective clinical treatment.
