Low Level LASER Therapy Versus Shock Wave Therapy in Shoulder Impingement Syndrome,SHIMAA N. ABO ELAZM and OLFAT A. KANDIL
Abstract
The Purpose: Of this study was to investigate the effects of Low Level LASER Therapy (LLLT) versus Shock Wave in treatment of shoulder impingement syndrome.
Subjects: Forty patients of both gender (21 females and 19 males) diagnosed as shoulder impingement syndrome with mean age (41.35±3.25) years represented the sample of the study. They were recruited from the Hospital of Misr University for Science and Technology.
Design: Forty patients were evaluated pretreatment and post treatment for shoulder pain severity, shoulder functional disability, shoulder flexion, abduction and internal rotation motions.
Material: Radial Extracorpreal shockwave device and Gallium arsenide low level LASER therapy apparatus were used for treatment. Guymon Goniometer, visual analogue scale (VAS) and quick disability questionnaire were used for evaluation.
Methods: Forty patients were randomly distributed into two equal groups; each group consisted of 20 patients. Group I with a mean age of (49.39±3.91) years received 12 sessions of LASER therapy (total dose of 14.4 J/session, 3 sessions per week) and therapeutic exercises (strengthening exercises, and stretching exercises for shoulder joint) 3 times per week, for 4 consecutive weeks. Group II with a mean age of (50.33±3.22) years received 12 sessions of shock wave (6000 shock, 2000 shocks per session, 3 sessions, 1 weeks a part, 022mJ/mm2) and the same therapeutic exercises as group I (3 times per week, every other day, for 4 consecutive weeks).
Results: The results revealed significant difference in all measured variables regarding group I and II when comparing pre and post treatment mean values (p<0.0001). Significant improvement was observed in favor of group I in all measured variables (pain severity, shoulder disability index and range of motion).
Conclusion: Both LLLT and the shock wave therapy had a significant effect on decreasing shoulder pain severity, shoulder functional disability, increasing in shoulder flexion, abduction and internal rotation motions. However, LLLT was more effective in treatment of patients with shoulder impinge-ment syndrome.
