You are treating a patient who has a diagnosis of left shoulder adhesive capsulitis with an accessory motion dysfunction and a noted loss of proper scapulohumeral rhythm. Which of the following interventions would most likely help achieve proper scapulohumeral rhythm?
1. Strengthening of the parascapular muscles and stretching of the glenohumeral structures
2. Protection of joint biomechanics with immobilization
3. Strengthening of the glenohumeral joint muscles at the end range
4. Manual stretching to achieve normal internal and external rotation at the glenohumeral joint
The solution will be posted in a few days.
