Use of Logistic Regression Analysis in the Diagnosis of Shoulder Impingement Syndrome

Centre for Health and Medical Physics, Queensland University of Technology, Queensland, Australia; 19 Kingston Drive, Flinders View, Queensland 4305, Australiamstieler{at}bit.net.au

Supraspinatus tendonitis secondary to subacromial impingement is one of the most common causes of shoulder pain.Subacromial impingement is a heter ogeneous condition with many possible causes, ranging from anatomical abnormalities of the coracoacromial arch to functional derangements allowing superior migration of the humeral head during elevation of the arm.Because of this heterogeneity, it is difficult to diagnose this condition with ultrasound using only 1 or 2 criteria.In this study, a wide range of diagnostic parameters was used in a logistic regression model to provide an accurate, objective method for the sonographic diagnosis of subacromial impingement in the intact rotator cuff.

Key Words: logistic regression analysis • shoulder impingement • rotator cuf
