Walking before an ultrasound assessment increases the enthesis score significantly.

摘要

Inflammatory enthesis involvement is a characteristic feature of spondy-loarthropathies (SpA); it is considered the primary lesion in this disease1. The MAdrid Sonographic Enthesis Index (MASEI) score was recently validated for SpA diagnostic classification2. MASEI scores range from 0 to 136, and a value > 18 was established as the best cutoff point to differentiate between cases and healthy controls (sensitivity of 83.3%, specificity 82.8%).Sporting activities such as running and aerobic exercise are known to result in foot and ankle injuries, such as tendon thickening, edema, and bur-sitis, that could influence ultrasound (US) assessment of enthesis3. To our knowledge, the effect of a mild sport activity on an US assessment of enthesis has never been studied. We investigated the influence of a 30-minute walk just before an US assessment of enthesis using the MASEI score.
