Rotation exercise classes did not improve function in women with non-specific chronic low back pain: A randomized single blind controlled study

BACKGROUND: Exercise is considered the first line of treatment for people with non-specific chronic low back pain (NSCLBP) but the ideal exercise type is currently unclear. Given the unique anatomical structure of the lower lumbar spine and the lumbosacral junction transverse-plane rotation exercises may be helpful for people suffering from pain in this region. OBJECTIVE: We aimed to examine the effect of spinal rotation exercises delivered in a group format on range of motion, pain level and function parameters in women with NSCLBP. METHODS: This was a randomized controlled single-blinded study. Thirty-five women with NSCLBP, participated in either a bi-weekly rotation exercise classes (n = 20) or a 'wait-list' control group (n = 15). The exercises aimed at improving lumbar mobility in the transverse plane. Pain rated on a Visual Analog Scale, back specific disability (Rolland Morris questionnaire), and lumbar range of motion (flexion, extension and left and right rotation) were taken prior to intervention, immediately following 4 weeks of intervention and 8 weeks later. RESULTS: There were no significant differences for either group (p > 0.05) on all dependent variables at all times of measurements. CONCLUSIONS: A specific group program of rotation exercises had no effect on the functional status, pain level and lumbar range of motion in women with NSCLBP.
