Detection of Early Scapular Dyskinesis

Detection of Early Inflammatory Versus Early Mechanical Scapular Dyskinesis

This study is a prospective blind contrast between periscapular muscle thickness measured with MSUS in patients with early AS in comparison to patients with mechanical dyskinesis and to correlate it with EMG findings.
