ABSTRACT
OBJECTIVES: To explore the therapeutic effect of Fu's subcutaneous needling at myofascial trigger points (MTrPs) on pain, lumbar mobility and the quality of life in patients with lumbar disc herniation (LDH), so as to provide clinicians with new ideas and methods in treating LDH. METHODS: One hundred patients with LDH admitted to department of rehabilitation medicine of the affiliated hospital of Chengdu University of Traditional Chinese Medicine from January 2022 to January 2023 were collected as the subjects, and they were randomly divided into an observation group and a control group, 50 cases in each one. In the observation group, the spreading technique of Fu's subcutaneous needling was delivered at MTrP. In the control group, the routine acupuncture was applied to Shenshu (BL23), Weizhong (BL40) and MTrP. The treatment was given 3 times weekly, for 2 weeks in the two groups. The score of visual analogue scale (VAS) was evaluated before treatment, at the moment after the 1st treatment completion and after 2 weeks of treatment, separately, and the inclinometer was adopted to measure the range of motion (ROM) of the lumbar flexion, extension and lateral flexion. The numbers of MTrPs and their distribution were recorded before treatment and after the completion of a 2-week treatment in the two groups. Before treatment and in 4 weeks of follow-up, using SF-36 scale, the score of the quality of life was evaluated. The incidence of adverse effects was recorded. RESULTS: At the moment of the 1st treatment completion and after 2 weeks of treatment, VAS score and ROM of the lumbar region were significantly improved in comparison with those before treatment in the two groups and the improvement was superior in the observation group compared with the control group (P<0.05, P<0.01). After 2 weeks of treatment, the total number of MTrPs and the counts of MTrPs in each muscle zone were reduced when compared with those before treatment (P<0.05). In the observation group, the total number of MTrPs and numbers of MTrPs in the zones of quadratus lumborum, musculi multifidus and musculi iliocostalis lumborum decreased significantly when compared with the control group (P<0.05), while the difference was not significant in the numbers in the zone of musculi glutaeus medius between the two groups. In 4 weeks of follow-up, the scores of SF-36 scale were improved in comparison with those before treatment in each group and the result in the observation was better (P<0.05). No any adverse events occurred during treatment in the two groups. CONCLUSIONS: Fu's subcutaneous needling is effective for reducing the numbers of MTrPs and improving analgesia, ROM of the lumbar region, as well as the long-term quality of life in the patients with LDH.
