title: Analysis of three-dimensional motion of the glenohumeral joint in impingement syndrome.
abstract: BACKGROUND
  Impingement syndrome (IS) is one of the most common causes of progressive dysfunctions of the shoulder joint. The aim of the study was to evaluate the changes in the joint's mobility in patients with IS and to find correlations between the angular values of particular motion ranges.
  
  
  METHODS
  The study involved 58 people aged 24-85 years, treated for IS from 2004 to 2006. The average duration of the disease was 40 months. A comparative examination of active mobility on the healthy and affected side was carried out according to the SFTR method.
  
  
  RESULTS
  A comparison of mean values of the motion ranges indicated significant limitations of active mobility in the affected shoulder. The greatest mobility deficit was found in the external rotation range. Moreover, there was a statistically significant correlation between the angular values of internal rotation and the values of the remaining motion ranges.
  
  
  CONCLUSIONS
  Impingement syndrome.
