[Head acupuncture combined with exercise therapy for nonspecific low back pain：a randomized controlled trial]

To compare the clinical effect between head acupuncture combined with exercise therapy and conventional acupuncture for nonspecific low back pain.

A total of 64 patients with nonspecific low back pain were randomized into an observation group (32 cases, 2 cases dropped off) and a control group (32 cases, 2 cases dropped off). In the control group, conventional acupuncture was applied at Jiaji (EX-B 2) of L₁ to L₃, ashi point, Shenshu (BL 23), Dachangshu (BL 25), Yaoyangguan (GV 3) and Weizhong (BL 40). The observation group was treated with head acupuncture combined with exercise therapy, head acupuncture was applied at foot-motor-sensory area on the healthy side and Cuanzhu (BL 2), Tongziliao (GB 1) on the affected side, and McKenzie therapy was performed during retention. The needles were retained for 40 min, once a day, continuous treatment for 6 days with the interval of 1 day, 14 days were required in the two groups. Before and after treatment, the pain visual analogue scale (VAS) score, Oswestry disability index (ODI) score and infrared thermography temperature of pain area in the low back were compared in the two groups.

Compared before treatment, the VAS and ODI scores after treatment were decreased in the two groups (P<0.01), and those in the observation group were lower than the control group (P<0.01). Compared before treatment, the infrared thermography temperature of pain area in the low back after treatment was increased in the two groups (P<0.01), and that in the observation group was higher than the control group (P<0.01).

Head acupuncture combined with exercise therapy could relieve pain, improve dysfunction and increase the local temperature of pain area in patients with nonspecific low back pain, and its curative effect is better than conventional acupuncture.
