Abstract: Objective To observe the clinical effect of chiropractic on nonspecific low back pain (NLBP). Methods From July, 2016 to January, 2018, 90 patients with NLBP were randomly divided into control group (n = 45) and observation group (n = 45). Both groups accepted core stabilization exercises (CSE) and routine physical therapy, and the observation group received chiropractic additionally. They were treated for four weeks and followed up for six months. Before, and two and four weeks after treatment, and at six-month follow-up, they were evaluated with Visual Analogue Scale (VAS), Oswestry Disability Index (ODI), abdominal and dorsal muscle endurance test (AMET) and waist active range of motion (AROM). Results Two and four weeks after treatment, the result of VAS, ODI, AMET, and waist AROM improved significantly in both groups (P < 0.05), and they were better in the observation group than in the control group (t > 0.263, P < 0.001). At six-month follow-up, the scores of VAS and ODI improved significantly (P < 0.05), and were better in the observation group than in the control group (t > 5.911, P < 0.001). Conclusion CSE and routine physical therapy combined with chiropractic could better reduce the pain, improve the dysfunction, and increase the spinal stability for patients with NLBP.
