Efeitos de um protocolo de pilates on-line em indivíduos com dor lombar crônica: ensaio controlado aleatorizado

Abstract

Objective: To evaluate the effects of the Pilates method, performed online, in individuals with chronic low back pain. Methods: Participated in the research 78 volunteers with chronic low back pain divided into two groups: Pilates on-line group (GP) and control group (GC). The GC received information about pain education. In addition to access the same information, the GP underwent 16 sessions of Pilates, performed online. Both interventions lasted eight weeks. The following outcomes were assessed pre- and post-intervention: pain intensity, disability, and kinesiophobia. In addition to these, the individual global perception was measured only post-intervention. Intergroup comparisons were performed using Student's t-test for independent samples with Welch correction. The effect of the variable time (Pre x Post) was evaluated by a paired t-test for parametric variables and a Wilcoxon test for non parametric variables. The significance level was 5% with a 95% confidence interval. Results: Pain reduction in the last 24 hours (p=0.008) and at rest (p=0.008) was observed for the GP in the intragroup analysis. The GC also showed similar results, with improvement of pain sensation assessed with the individual at rest (p=0.02) and in movement (p=0.01). There was no difference for any of the variables analyzed between groups. Conclusion: Online Pilates was not superior to pain education for the outcomes analyzed, but it seems that both interventions contribute to decreasing pain over time in individuals with chronic low back pain.
