- Abstract
Purpose: Pectoralis minor (PM) muscle length is believed to play an important role in shoulder pain and dysfunction. Adaptive length decrease of PM may cause not only soft tissue alterations and also alteration of scapular motions. Two different PM length measurements are described in literature. However, the relation of these measurements with scapular resting position has not been investigated before. The aim of this study is to assess two different PM length measurements in relation with scapular resting position in asymptomatic individuals. Methods: Twenty-eight asymptomatic individuals (mean age 16.2±2.2 years) were included in this study. Demographic data of participants, active and passive shoulder range of motion and two different pectoralis minor length measurements were recorded. For the direct measurement of PM length was determined by calculating directly the length between the posterior acromion and the bed in supine position. Second, for indirect measurement length between the coracoid process and fourth rib in supine position with tape and measurements were recorded in centimeters. Three-dimensional scapular position during rest was recorded using electromagnetic system (Motion Monitor®, USA). Scapular internal-external rotation, upward-downward rotation and anterior-posterior tipping were assessed. Spearman Correlation Analysis was used to assess the relationship between scapular kinematics and the both PM length measurements. Results: Direct measurement demonstrates moderate correlation with scapular anterior tipping (p=0.035, r=0.401) and internal rotation (p=0.024, r=0.425 in 3D scapular resting position. However, indirect measurement is not correlated with scapular resting position. Significant association was not observed between direct and indirect PM length measurement. Conclusion: The results of this study showed that scapular resting position was more related to direct measurement of PM muscle length when compared to indirect measurement in asymptomatic individuals. Therefore, direct measurement could help clinician to evaluate the changes in scapular kinematics according to PM muscle tightness.
