Effect of High-Power Laser Therapy Versus Shock Wave Therapy on Pain and Function in Knee Osteoarthritis Patients: A Randomized Controlled Trial.

Objective: The aim of this study was to evaluate and compare the effects of extracorporeal shock wave therapy (ESWT) and high-intensity laser therapy (HILT), as outpatient physical therapy modalities, on knee osteoarthritis (KOA) patients. Materials and methods: The treatment program was completed by 40 individuals with stage II KOA (according to Kellgren and Lawrence) who were randomly allocated to one of two groups. They have had more than grade 3 pain on the visual analog scale (VAS) during activities for the last 3 months, with body-mass index less than 30 and no history of knee operation, fracture, cancer, or other neuromuscular or musculoskeletal diseases that may affect study results. The ESWT group (n = 20, mean age = 40.12 ± 9.45 years) received ESWT, 0.05 mJ/mm2, one session/week for 4 weeks, and the HILT group (n = 20, mean age = 46.62 ± 8.68 years) received HILT, 1500 mJ/cm2 in each session, three sessions/week for 4 weeks. Both groups received conservative physical therapy programs. Before and after 4 weeks of intervention, pain, physical function, and disability were assessed using a VAS, 6-min walking test, and the Western Ontario and McMaster Universities Osteoarthritis Index. Results: When the pre- and post-treatment mean values of dependent variables of both groups were compared, there were statistically significant improvements in both groups. Significant differences in the measured variables were also discovered in favor of the HILT group compared with the ESWT group. Conclusions: HILT showed a superior effect compared with ESWT on pain, physical function, and disability in chronic KOA patients. Pan African Clinical Trials Registry number: PACTR202007638955907.

Cryolipolysis versus laser lipolysis on adolescent abdominal adiposity.

BACKGROUND: Noninvasive body contouring is one of the fastest growing segments of the cosmetic aesthetic industry. There is increased public demand for procedures with fewer side effects and shorter recovery times. Cryolipolysis and Laser lipolysis have been used as treatments for localized body contouring. OBJECTIVE: To compare the effect of Cryolipolysis versus Laser lipolysis on adolescent's abdominal adiposity. DESIGN: Randomized, controlled trial. SUBJECTS: Forty-five obese adolescents of both sexes ranged in age from 13 to 16 years participated in this study were to be categorized into three groups of equal number (each group 15 subjects) randomly selected from population. METHODS: Participants were randomly assigned to three groups. Group A was received (Cryolipolysis and diet), Group B was received (Laser lipolysis and diet), Group C was received (only diet) all groups were observed for 8 weeks. Weight and height scale for (change in weight), tape measurement for (waist-hip ratio), skinfold caliper, and MRI. RESULTS: There was no significant difference between three groups post-treatment in BMI and body weight P-value were (0.2, 0.42, 0.67), respectively. There was a significant improvement for Cryolipolysis group in waist-hip ratio, Suprailiac skin fold, and subcutaneous adipose tissue than other groups P-value (0.001). CONCLUSIONS: Cryolipolysis has a favorable effect than Laser lipolysis in the reduction of waist-hip ratio, skin folds at Suprailiac level and subcutaneous adipose tissue (SAT), there is no significant difference between them in the reduction of BMI and body weight. All groups did not have an effect on VAT.
