This study investigated the association between clinical trials, clinical outcomes and prognosis risk of patients with chronic non-specific low back pain. Methodology: Twenty patients, older than 18 years, were selected by convenience and submitted to evaluation of clinical outcomes through a numeric pain rating scale and a disability questionnaire. To classify prognostic risk, we used the STarT Back questionnaire, and to evaluate transverse abdominal muscle recruitment, we used the following clinical tests: clinical rating scale (CRS); and measure of the thickness of the abdominal muscles using ultrasonography images (MEM-US). The tests were performed in a single day by a trained evaluator in random order. Pearson (r) and Spearman (rs) correlations were used to investigate the association. Results: The associations between the prognostic risk of low back pain with clinical outcomes, pain and disability, were moderate (r=0.68 and r=0.57, respectively). For CRS, associations with disability and prognosis risk were considered reasonable (r=-0.34 and r=-0.36, respectively). There were no associations with the MEM-US. In the low prognostic risk sample, the CRS's relationship with disability was considered from moderate to good, while pain correction was reasonable (rs=-0.62; and rs=-0.24, respectively). Conclusion: We observed an association between CRS and clinical outcomes and prognostic risk, with stratification, according to prognostic risk, that increases the relationship observed. Future studies should be conducted with new measures for the evaluation of abdominal muscle recruitment with larger samples.Downloads
