Abstract
Introduction. High-intensity laser therapy (HILT) appears to be effective for knee osteoarthritis (KOA). However, no recommendations exist for the optimal dosage of HILT in chronic KOA.
Aim of the study. This study examined how different dosages of HILT affect KOA pain and function.
Materials and methods. Fifty-one patients with third-degree knee osteoarthritis, aged 50–70 years, were randomly assigned to three equal groups. Group A received exercises and a dose of 1500 J of HILT. Group B received exercises and a dose of 3000 J of HILT. Group C received sham laser treatment along with exercises. Pain and function were evaluated using the numerical pain rating scale (NPRS) and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Groups were evaluated before and after a six-week treatment period.
Results. A mixed design multivariate analysis of variance (MANOVA) showed that pain and function significantly improved in all three groups after treatment (p < 0.001). Significant differences were observed between both active groups (A and B) and the control group. Between groups A and B, no significant differences were found (p > 0.05). However, descriptive analysis revealed that group B achieved greater improvements than group A.
Conclusion. In patients with chronic KOA, HILT at either 1500 J or 3000 J combined with exercises effectively reduced pain and improved function. To save time and energy, a dosage of 1500 J may be recommended.

Abstract
Background. Shoulder pain is very common problem in medical practice, ranked third after lower back and neck issues. Shoulder impingement syndrome is thought to be the most common reason for shoulder pain. It accounts for around 44% to 65% of all shoulder problems. Purpose. to compare between the effects of High Intensity Laser Therapy versus Radial Shock Wave Therapy in treatment of shoulder impingement syndrome. Methods. 45 patients were randomly enrolled into three equal groups. Group A (n = 15) received HILT plus conventional physical therapy program, Group B (n = 15) received RSWT plus the same conventional physical therapy program, and Group C (n = 15) received a conventional physical therapy program. The assessment were conducted pre and post treatment using the Visual Analogue Scale, Shoulder pain and disability index and electro goniometer to active shoulder flexion and abduction range of motion. Results. MANOVA test demonstrated a significant (P < 0.05) decrease in VAS and SPADI and a significant (P < 0.05) increase in shoulder flexion and abduction ROM in the three groups. VAS, SPADI, shoulder flexion, abduction ROM revealed that there was more improvement in-group A (P < 0.05). Conclusion: HILT showed a superior effect compared with RSWT on pain, function and shoulder flexion and abduction ROM in treatment of SIS.
