Effects of aerobic exercise on pain and disability in patients with non-specific chronic low back pain: a systematic review protocol.

Introduction: Aerobic exercise programs have been used for various health conditions, including musculoskeletal disorders. However, the literature is still limited regarding the effect of aerobic exercise on pain and disability in patients with chronic non-specific low back pain.
Methods: Search strategies will be performed in the following databases: PubMed, EMBASE ( https://www.embase.com ), CINAHL, PEDro, Lilacs, and Cochrane Central Register of Controlled Trials (CENTRAL). We will include randomized controlled trials in any language or date of publication. The primary outcomes will be pain and disability. The methodological quality and statistical reporting of each eligible trial will be evaluated using the 11-item PEDro scale. The strength of the recommendations will be summarized using the using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.
Discussion: This systematic review will provide a synthesis of current evidence on the effects of aerobic exercise in patients with chronic low back pain on pain and disability outcomes. This information can help healthcare professionals in decision-making related to the use of aerobic exercise in patients with low back pain. Following the guidelines, this systematic review protocol was registered on the Prospective International Register of Systematic Reviews (PROSPERO) number CRD42017071945.
