Brief Summary

Subacromial impingement syndrome, one of the most common causes of shoulder pain. In studies investigating the effectiveness of high-intensity laser in patients with subacromial impingement syndrome, it was stated that high-intensity laser reduced the complaints of patients in the early and late periods. However, there is no research examining the effect of high-intensity laser on the supraspinatus tendon. Therefore, the investigators aimed to investigate the effect of high-intensity laser on the supraspinatus tendon using shear wave elastography.

Detailed Description

Subacromial impingement syndrome, one of the most common causes of shoulder pain, occurs when the supraspinatus tendon, subacromial bursa or bicipital tendon becomes compressed between the acromion, coracoacromial ligament, coracoid process and/or acromioclavicular joint during shoulder movements. Several factors contribute to subacromial impingement syndrome, including weakening of the rotator cuff, capsular tension, poor scapulohumeral rhythm, and muscular imbalance in the upward rotation force of the scapula. Steroid and non-steroidal anti-inflammatory agents, physiotherapy applications, laser therapy, manual therapy, ESWT and active and passive normal joint movements involving the shoulder joint are frequently applied treatments in the treatment of subacromial impingement syndrome.

It is stated that high-intensity laser treatment can quickly produce photochemical and photothermic effects in deep tissue. Therefore, collagen production in tendons is promoted and blood flow, vascular permeability and cell metabolism can be increased. As a result of all these processes, tissue healing begins and painful stimuli decrease. In studies investigating the effectiveness of high-intensity laser in patients with subacromial impingement syndrome, it was stated that high-intensity laser reduced the complaints of patients in the early and late periods. However, there is no research examining the effect of high-intensity laser on the supraspinatus tendon. Therefore, in this study, the investigators aimed to investigate the effect of high-intensity laser on the supraspinatus tendon using shear wave elastography.

Primary Outcome Measures
NameTimeMethod
Elasticity Measurement2 weeks

In patients diagnosed with subacromial impingement syndrome as a result of physical examination, the degree of elasticity of the supraspinatus tendon and supraspinatus muscle on the relevant side will be evaluated numerically by Shear Wave elastography. All patients will be scanned by an expert radiologist using a high-resolution broadband linear probe with a Samsung RS 85 Prestige device. While the patients are sitting comfortably and the arm is in a neutral position, the linear probe will be placed parallel to the supraspinatus tendon and the tendon will be displayed in the longitudinal direction. Velocity and elasticity values of the muscle in kPa will be measured using 3 mm diameter range of interest (ROIs) with the help of Shear Wave elastography in the supraspinatus tendon at a distance of 0.5-1.5 cm from the tuberculum majus. For each patient, the measurement will be repeated three times and the average of these three values will be recorded.

Secondary Outcome Measures
NameTimeMethod
Pain assessment2 weeks

The severity of patients' shoulder pain will be evaluated with a visual analog scale (VAS). VAS: The left end of a 10 cm straight line represents no pain, and the right end represents unbearable pain. The patient will be asked to mark the pain he feels on the VAS scale during the test, and then this value will be measured and recorded with the help of a ruler.

Functional level2 weeks

The functional level of the shoulder will be evaluated with the Shoulder Pain and Disability Scale. This scale consists of a total of 13 questions, where each question is scored between 0-10. The scores from the first 5 questions measure the pain level out of 50, and the scores from the next 8 questions measure the disability level out of 80. A high score from the scale indicates a high level of pain and disability.
