Pathophysiological factors and their correlation with non-surgical outcome in patients with isolated subacromial pain syndrome

Introduction Patients with subacromial pain syndrome (SAPS) are typically referred to physiotherapy as first line of treatment. Only half of patients get a satisfactory treatment outcome from this. Acromial morphology, poor scapular control, and impingement are pathophysiological factors associated with SAPS. These are expressed varyingly in SAPS-patients, and could be associated to treatment outcome. The aim was to investigate if acromial morphology, scapular control, and ultrasonographic impingement were associated with outcome from 3-months of treatment, in SAPS-patients.
