Dr. Robert LaPrade recently completed a two-part study in the Journal of Orthopaedic & Sports Physical Therapy on the Comparison of 3-Dimensional Shoulder Complex Kinematics in Individuals With and Without Shoulder Pain. Shoulder pain is the second most common musculoskeletal complaint by the general population. The majority of clinical diagnosis for shoulder pain is “impingement”. However, the diagnosis is so broadly applied that different tissue pathologies and various and, often conflicting pathomechanics may contribute to the pain.

In part one, the objective of the study was to compare sternoclavicular, acromioclavicular, and scapulothoracic joint motion between symptomatic and asymptomatic individuals during shoulder motion performed in 3 plans of humerothoracic evaluation. The results of this study show that differences in shoulder complex kinematics exist between symptomatic and asymptomatic individuals.

In part two, the objective is to compare differences in glenohumeral jont angular motion and linear translations between symptomatic and asymptomatic individuals during shoulder motion performed in 3 planes of humerothoracic evaluation. The results of this study show differences in glenohumeral kinematics exist between symptomatic and asymptomatic individuals.
