Effect of Laser Therapy on Chronic Osteoarthritis of the Knee in Older Subjects
摘要： Introduction: Osteoarthritis (OA) is a common degenerative joint disease particularly in older subjects. It is usually associated with pain, restricted range of motion, muscle weakness, difficulties in daily living activities and impaired quality of life. To determine the effects of adding two different intensities of low-level laser therapy (LLLT) to exercise training program on pain severity, joint stiffness, physical function, isometric muscle strength, range of motion of the knee, and quality of life in older subjects with knee OA. Methods: Patients were randomly assigned into three groups. They received 16 sessions, 2 sessions/week for 8 weeks. Group-I: 18 patients were treated with a laser dose of 6 J/cm2 with a total dose of 48 J. Group-II: 18 patients were treated with a laser dose of 3 J/cm2 with a total dose of 27 J. Group-III: 15 patients were treated with laser without emission as a placebo. All patients received same exercise training program including stretching and strengthening exercises. Patients were evaluated before and after intervention by visual analogue scale (VAS), the Western Ontario and McMaster Universities Osteoarthritis (WOMAC) index for quality of life, handheld dynamometer and universal goniometer. Results: T test revealed that there was a significant reduction in VAS and pain intensity, an increase in isometric muscle strength and range of motion of the knee as well as increase in physical functional ability in three treatment groups. Also analysis of variance (ANOVA) proved significant differences among them and the post hoc tests (LSD) test showed the best improvements for patients of the first group. Conclusion: It can be concluded that addition of LLLT to exercise training program is more effective than exercise training alone in the treatment of older patients with chronic knee OA and the rate of improvement may be dose dependent, as with 6 J/cm2 or 3 J/cm2.

Evaluation of life quality of patients submitted to cataract surgery with implants of monofocal, bifocal and multifocal lenses
摘要： Purpose: Providing an objective and subjective evaluation of life quality and satisfaction level of the patients who underwent cataract surgery with implant of bifocal, multifocal and monofocal lenses. Methods: Bifocal lenses were implanted in 72 patients, aspheric multifocal lenses in 16 patients, apodized multifocal lenses in 20 patients and Monofocal lenses were implanted in 63 patients. The patients answered a 47 question questionnaire, whose results were evaluated and analyzed. Results: The level of satisfaction of the patients implanted with bifocal and multifocal lenses was significantly higher than of those with monofocal lenses (kruskal – Wallis test, p< 0.001 followed by the Dunn test, p< 0.05). As to the comparison of monofocal lenses with bifocal and multifocal lenses, the near vision without correction was considerably lower in patients with monofocal lenses (Z test p< 0.001). The patients with monofocal lenses without correction presented a much lower capacity of reading newspapers or books and as far as manual work than the ones with bifocal and multifocal lenses (Z test, p<0.001). Conclusion: The result of this study shows that the patients who received the bifocal and multifocal lenses had a remarkable improvement in their visual acuity for the near vision, being pleased with their general vision without wearing glasses. This is because they were able to read books and newspapers, write checks, fill out forms, do sports, shave or put on make-up, hence having high quality of life without correction.
