Efficacy of low-level laser therapy combined with exercise for subacromial impingement syndrome: A randomised controlled trial.
Appraisals:
Random sequence generation; Allocation concealment; Blinding of participants and personnel (?); Blinding of outcome assessment. (by RobotReviewer)
The study contains no weaknesses. Based on this result you should conclude that the trustworthiness of the study is high (90%). This means there is a 10% chance that alternative explanations for the effect found are possible. The effect size was not reported and 95% CI was OK. (by CAT for RCTS)

Local/Technic
“…three insertion points each in the supraspinatus muscle tendon, on the subacromial bursa, and along the bicipital groove.” Before exercise.
Periodicity
three times a week for 8 weeks
Obs:
Comments: “Low-level laser therapy combined with exercises reduce pain intensity, improve shoulder function and reduces pain intensity and medication intake over 3 months.”
