| Objective: To observe the clinical efficacy of the spinal manipulation therapy and routine physiotherapy (medium and high frequency) for patients with chronic nonspecific low back pain. Methods: Forty patients with chronic nonspecific low back pain were randomly divided into treatment group (20 cases) and control group (20 cases). Patients in control group received routine physiotherapy (medium and high frequency), and those in the treatment group were given the spinal manipulation therapy. Visual analogue scale (VAS) and the Oswestry Disability Index (ODI) were performed before treatment, immediate after treatment, 1 month and 3 months after treatment. The anterior flexion of lumbar spine was recorded before treatment, after the first treatment and after the last treatment. Before and after treatment, the surface EMG flexion-relaxation ratio (FRR) was recorded. Results: VAS scores in two groups after treatment, at 1st month and 3rd month after treatment were significantly lower than those before treatment (P<0.05), and those in the treatment group were lower than those in the control group at each time point (P<0.05). After treatment, the ODI in the treatment group was significantly lower than that before treatment (P<0.05), and there was no significant difference in the control group before and after treatment. ODI in treatment group was significantly lower than that in control group (P<0.05); At 1st month and 3rd month after treatment, ODI in two groups was significantly lower than that before treatment (P<0.05), and there was no significant difference between two groups. After the first time of treatment, the number of lumbar flexion in the treatment group was significantly greater than that before treatment and that in the control group (P<0.05), and in the control group there was no significant difference between the first time of treatment and before treatment. After treatment, lumbar flexion degree in two groups was significantly higher than that before treatment (P<0.05), and there was no significant difference between two groups. After treatment, FRR in two groups was significantly increased as compared with that before treatment (P<0.05), and that in the treatment group was higher than in the control group (P<0.05). Conclusion: The spinal manipulation therapy has a certain clinical efficacy for patients with chronic nonspecific low back pain, which can relieve pain as soon as possible, accelerate the recovery process of the disease, improve the range of lumbar motion, reduce the tension of lumbar and back muscles, and relax the muscle group of lumbar and back. |
