PURPOSE:Low back pain (LBP) is common among female freestyle wrestlers and it's recovery is difficult. The aim of this study was to explore the effects of rehabilitation on chronic nonspecific low back pain (CNLBP) among female freestyle wrestlers. METHODS: In the current study, 16 subjects were selected through physical examination combined with a questionnaire assessment of fear-avoidance beliefs of all athletes in a women's freestyle wrestling team at Henan Heavy Sports Management Center. This study was approved by the Ethics Committee of Zhengzhou University. Informed consent was obtained from each subject. A rehabilitation training program including functional training, muscle strength training and flexibility training was developed on the basis of participants' physical signs and was conducted for 6 weeks, three times a week for 2 hours each time. Before and after the rehabilitation, the degree of pain, functional disability index, trunk muscle strength, trunk flexibility, McGill pain scale and the Japanese Orthopaedic Association (JOA) of LBP scale were measured. RESULTS:McGill pain scale scores were significantly decreased (15.82±5.83 to 9.18±4.00, P=0.002). The improvement rate of CNLBP on the JOA LBP rating scale was significantly different between pre-and post-scores (15.64±3.38 to 22.36±2.11, P<0.001). Seat and reach scores were significantly increased (13.65±3.38 to 19.35±2.83, P=0.004). Hip flexion (40.46±8.56 to 43.58±7.47, t=-2.99, P=0.022)and extension strength(26.48±4.99 to 28.95±4.64, t=-5.10, P=0.004) were significantly increased . CONCLUSIONS:The rehabilitation training programme used in this study significantly improved CNLBP pain degree, dysfunction and hip flexion and extension strength.
