Function-Related Tests for Subjects With Stiff Shoulders: Reliability and Validity
Recruitment status was: Recruiting
Shoulder-related dysfunction (SD) is a common health problem in various patient populations. SD can affect an individual's ability to function independently, consequently decreasing quality of life. A battery of simple measurable function-related tests for patients with SD is important.
The purpose of this study is to test the reliability, validity, and potential clinical use of a battery of function-related tests in patients with SD. Additionally, the biomechanical characteristics of the battery of function-related tests will be analyzed in terms of three-dimensional shoulder complex movements and associated muscular activities.
Repeated measurements and descriptive study
The affected arms of 60 symptomatic patients with SD will be assessed by two clinicians as well as by one clinician twice to calculate intertester and intrarater reliabilities. Assessment will include self-report measures and the battery of function-related tests (hand-in-neck, hand-to-scapula, hand-to-opposite-scapula, and modified Kibler's lateral scapular slide test). Pearson correlation or Spearman's rho correlation coefficients will be calculated and the correlation matrices will be examined for evidence of convergent and discriminative validity among pain, disability, and function-related measures in patients with SD. Principle axis factor analysis will be performed on the kinematic measurements and muscular electromyography (EMG) activities to characterize the factor loading of each task.
