Background. The effect of high-level laser on shoulder mobility in subacromial impingement syndrome had been not investigated yet. Objectives. to investigate the effect of high- level laser therapy on shoulder mobility in subacromial impingement syndrome. Design. A Prospective, Randomized, pre - post- Test, controlled trial. Setting. outpatient clinic of Cleopatra Hospital {u2013} Egypt. The Study was conducted between June 2017 and Feb 2018. participants. forty Patients who were diagnosed with 1 - 2 stage impingement syndrome pain was Randomly divided into two equal groups. Interventions. Group (A) received a program of Neodymium- yttrium aluminum Garnet Laser 1064 nm wave Length Hiro 3 high level pulsed Laser was used in the study, Power of 8 W, dose of 12 J/cm2 and Total maximum energy of 10000 J were Applied for 15 min and duration for single impulse 150 `us, fluency 760 mj, two sessions per week over six weeks' period in addition to exercise Group (B) Received Exercise in the form of Pendulum Ex. For 5 minutes, strengthen Ex for Anterior fiber of deltoid, stretching Ex for sub scapularis muscle and anterior and posterior capsule. Main outcome measure. Visual Analogue Scale (VAS), electro goniometer, Ultrasonography Results. There was a statistically significant Reduction in VAS score, and improvement of mobility of shoulder in laser group compared with control group (p< 0.05) Conclusion. High level laser Therapy was yielding more improvement for shoulder mobility in impingement syndrome
