Abstract
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 – 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.
