Brief Summary
Arthritis of the shoulder glenohumeral joint is a growing problem in an aging population. Treatment options for glenohumeral arthritis can be grouped into three main categories: 1) shoulder replacement surgery, 2) injections (corticosteroid, hyaluronic acid and PRP) and physical therapy (PT). Surgery comes with risks and the potential for implant failure or revision over time. Therefore, it is typical for doctors to prescribe injections and/or PT before discussing surgery. Sometimes, insurance companies will require PT before considering a shoulder operation. It is unknown if PT is effective for improving function or pain with patients with glenohumeral arthritis. The aim of this study is to compare pain and functional outcomes after undergoing a 12 week PT program, at home PT exercises or delaying conservative treatment.

Outcome Measures
Primary Outcomes (2)
Visual analog scale (VAS)
measures pain from 0 being none and 10 as the worst pain ever felt.
Time 0, 6 weeks, 12 weeks, 1 year
American Shoulder and Elbow Surgeons (ASES)
This score is a 100-point shoulder evaluation tool divided evenly into a pain subscore (50 points) and an activities of daily living (ADL) function subscore (50 points). Higher scores indicate less pain and better shoulder function.
Time 0, 6 weeks, 12 weeks, 1 year
