Hi 🙂 Working with a physician or physical therapist is always the first line of action, however, they often end treatment too soon. If she was not seeing a therapist to begin with I would refer her out to one. If she does have a therapist, I usually develop an exercise program based on a detailed assessment and send it over the the therapist for approval. Sometimes this helps get the ball rolling. Exercises listed above and other exercises such as shoulder clocks, and foam roller thoracic extension help. In my experience, frozen shoulders can come from a variety of things as mentioned above, thoracic kyphosis usually makes it worse as when someone cannot extend through the thoracic spine they create problems in the shoulder as the shoulder takes the brunt of the shoulder movement, especially overhead movements. A good postural assessment will help guide you, the ACE shoulder assessments and keeping the shoulder and thoracic spine mobile is imperative.
