About

Randomized crossover trial evaluating the impact of exercise training sequence of axioscapular and rotator cuff exercises in patients diagnosed with subacromial impingement syndrome.

Full description

While physical therapy is an effective element in the rehabilitation of rotator cuff (RC) disease, the most effective sequence of training interventions has not been defined. The purpose of this study is to determine if there is a difference in pain or function in patients who are given RC strengthening prior to or after initiating scapular stabilization exercises.

The study was a prospective randomized crossover design. 26 men and 14 women, mean age 51, diagnosed with subacromial impingement syndrome (SAIS) were randomly assigned to one of two groups for a comprehensive and standardized rehabilitation program over six visits at an orthopedic outpatient clinic. One group was prescribed a 4-week program of scapular stabilization exercises while the other group began with RC strengthening exercises. The crossover design had each group add the previously excluded four exercises to their second month of rehabilitation.
