Biopsychosocial Contributors to Irritability in Individuals With Shoulder Pain
Trial Parameters
Brief Summary
Irritability was defined by Geoffrey Maitland as the vigor of activity to provoke symptoms, the severity of symptoms, and time for symptoms to subside. Irritability is deeply embedded in the physical therapy clinical decision-making process. However, the mechanisms contributing to irritability are unknown. Therefore, the purpose of this study is to characterize pain sensitivity and pain-related psychological factors by irritability level in individuals with shoulder pain.
