A randomized controlled trial comparing a comprehensive supervised training regimen with a validated home-based regimen for subacromial impingement syndrome.
The purpose of the study is to compare a comprehensive supervised training regimen (STR) based on latest evidence including heavy slow resistance training with a validated home-based regimen (HTR). We hypothesized that the STR would be superior to the HTR. Randomised control trial with blinded assessor. 126 consecutive patients with subacromial impingement syndrome were recruited and equally randomised to 12 weeks of either supervised training regimen (STR), or home-based training regimen (HTR). Primary outcomes were Constant Score (CS) and Shoulder Rating Questionnaire (SRQ) from baseline and 6 months after completed training. Results were analyzed according to intention-to treat principles.

Shoulder constant score
Functional assessment of the shoulder
Time frame: 6 months after ended training
Shoulder Rating Questionnaire
Self-administered questionnaire
Time frame: 6 months after ended training
Passive motion
Shoulder flexion, measurement in degrees; Shoulder abduction, measurement in degrees; Shoulder internal rotation, measurement in degrees; Shoulder external rotation, measurement in degrees.
Time frame: 6 months after ended training
Active motion
Shoulder flexion, measurement in degrees; Shoulder abduction, measurement in degrees; Shoulder internal rotation, measurement in degrees; Shoulder external rotation, measurement in degrees.
Time frame: 6 months after ended training
Visual Analogue Scale
Measurement of pain on a 10 cm scale, where 0 indicates no pain, and 10 worst pain for the following muscle tests: full can test, empty can test, lift off test, resisted external rotation, palm-up test, Yergason´s test.
Time frame: 6 months after ended training
Neer test
Stabilization of the patient's scapula with one hand, while passively flexing the arm while it is internally rotated. If the patient reports pain in this position, then the result of the test is considered to be positive (rated positive = 1 and negative = 0).
Time frame: 6 months after ended training
Hawkins test
Placing the patient's shoulder in 90 degrees of shoulder flexion with the elbow flexed to 90 degrees, and afterwards internally rotating the arm. The test is considered to be positive if the patient experiences pain with internal rotation (rated positive = 1 and negative = 0).
