Abstract

The Low Flexion (LF) test is a new clinical test to quantify glenohumeral joint (GHJ) posterior capsule tightness (PCT). This test quantifies the amount of GHJ internal rotation range of motion (ROM) with the arm held at 60° of flexion. Although this test has been shown to be a reliable and valid method to assess PCT, there is concern that variation in scapula position or lack of scapula stabilization during the measurement may affect the test. Therefore, the purpose of the present study is to analyze scapula positioning during administration of the LF test in asymptomatic individuals to determine the relationship of scapula position and stability on the measurement. The participants will be between 18 and 60 years and without shoulder pain and both shoulders will be measured. The 3-D scapula positioning during the LF test will be recorded by an electromagnetic tracking device. Scapula orientation at three distinct positions of the measurement will be compared at each shoulder and between sides using repeated-measures ANOVA with statistical significance set at p < 0.05. (AU)
