High-intensity cardiorespiratory and strength exercises reduced emotional distress and fatigue in patients with axial spondyloarthritis: a randomized controlled pilot study

摘要

Objective: To investigate the effect of high-intensity exercise on emotional distress, fatigue, and ability to do a full day's activities in patients with axial spondyloarthritis (axSpA).Method: A total of 28 physically inactive axSpA patients were randomized to either an exercise group (EG), which performed 12weeks of cardiorespiratory and strength exercises, or a control group (CG), which received treatment as usual. The outcomes reported in this paper are secondary outcomes in the trial and included emotional distress (General Health Questionnaire-12, 0-36, 36=worst), fatigue [numeric rating scale (NRS), 0-10, 10=worst], and ability to do a full day's activities (NRS, 0-10, 10=worst). Post-intervention differences were assessed by analysis of covariance with baseline values as covariates.Results: Twenty-four patients were included in the analyses. All patients in the EG followed the exercise protocol. The EG had a statistically significant beneficial effect [mean group differences (95% confidence interval)] on emotional distress [-5.8, (-9.7, -1.9), p0.01], fatigue [-2.4, (-4.3, -0.4), p=0.02], and ability to do a full day's work [-2.2, (-3.9, -0.4), p=0.02] compared to the CG.Conclusion: This pilot study showed promising effects of cardiorespiratory and strength exercises on emotional distress, fatigue, and ability to do a full day's activities in patients with axSpA. The findings need to be confirmed in a larger trial.
