Abstract
Purpose
This study was designed to assess the effects of a rehabilitation program on clinical symptoms, subacromial space parameters and the supraspinatus vascularity in individuals with subacromial impingement syndrome (SIS).
Methods
Thirty-five participants (exercise group with SIS [EG]=11, non-exercise group with SIS [NEG]=10, control group [CG]=14) took part in this study. Only EG participated in 6-week rehabilitation program. Outcomes were evaluated at baseline, 6 weeks, and 10 weeks. Changes in symptoms and functional limitations were assessed using Shoulder Pain and Disability Index (SPADI) questionnaire. Changes in acromiohumeral distance (AHD) and supraspinatus tendon thickness (STT)/AHD were assessed using ultrasonographic measures. Quantitative analysis of tendon blood flow was performed by determining four regions of interest with power Doppler quantification and analysis software to normalize data for interpretation of the mean ratio of colored pixel to the region of interest (vascularization index [VI]) and the intensity per pixel (flow index [FI]).
