Patients Undergoing Shoulder Stabilization Surgery Have Elevated Shoulder Activity Compared With Sex- and Age-Matched Healthy Controls

Background:Shoulder activity level may be a risk factor for shoulder instability, an indication for surgical intervention, and a risk factor for failure of operative stabilization.Hypothesis:Patients undergoing shoulder stabilization surgery have a higher activity level compared with sex- and age-matched healthy controls.Study Design:Cross-sectional study.Level of Evidence:Level 2.Methods:Patients undergoing shoulder stabilization surgery aged 18 to 50 years were prospectively enrolled. As part of data collection, patients completed a previously validated shoulder activity scale, which generates a score reporting frequency of activity ranging from 0 (least active) to 20 (most active). The activity level of these patients was compared with sex- and age-matched norms for a healthy population with no history of shoulder disorders.Results:A total of 409 subjects (343 male, 66 female) undergoing shoulder instability surgery completed the activity scale. Seventy-seven percent of patients had higher shoulder act...
