High intensity interval training (HIIT) has been shown to benefit patients with psoriatic arthritis (PsA). However, magnetic resonance (MR) imaging has uncovered bone marrow edema (BME) in healthy volunteers after vigorous exercise. The purpose of this study was to investigate MR images of the spine of PsA patients for changes in BME after HIIT. PsA patients went through 11 weeks of HIIT (N = 19, 4 men, median age 52 years) or no change in physical exercise habits (N = 20, 8 men, median age 45 years). We acquired scores for joint affection and pain and short tau inversion recovery (STIR) and T1-weighted MR images of the spine at baseline and after 11 weeks. MR images were evaluated for BME by a trained radiologist, by SpondyloArthritis Research Consortium of Canada (SPARCC) scoring, and by extraction of textural features. No significant changes of BME were detected in MR images of the spine after HIIT. This was consistent for MR image evaluation by a radiologist, by SPARCC, and by texture analysis. Values of textural features were significantly different in BME compared to healthy bone marrow. In conclusion, BME in spine was not changed after HIIT, supporting that HIIT is safe for PsA patients.
高强度间歇训练（HIIT）已被证明对银屑病关节炎（PsA）患者有益。然而，磁共振（MR）成像发现健康志愿者在剧烈运动后出现骨髓水肿（BME）。本研究的目的是调查PsA患者脊柱的MR图像，以观察HIIT后BME的变化。PsA患者进行了11周的HIIT（N = 19，4名男性，中位年龄52岁）或体育锻炼习惯无变化（N = 20，8名男性，中位年龄45岁）。我们在基线和11周后获取了关节受累和疼痛评分以及脊柱的短tau反转恢复（STIR）和T1加权MR图像。由一名训练有素的放射科医生、加拿大脊柱关节炎研究联盟（SPARCC）评分以及通过提取纹理特征对MR图像进行BME评估。HIIT后脊柱的MR图像中未检测到BME的显著变化。这在放射科医生、SPARCC以及纹理分析的MR图像评估中是一致的。与健康骨髓相比，BME中纹理特征的值有显著差异。总之，HIIT后脊柱的BME没有变化，支持HIIT对PsA患者是安全的。
