Background: We examined the feasibility and effectiveness of a community-based progressive AQUATIC EXERCISE program for communitydwelling older adults, with moderate to severe knee osteoarthritis (OA). Objectives: The purposes of this study were to 1, assess the effects of a progressive AQUATIC EXERCISE program on the walking ability, stair climbing ability, quadriceps muscle strength, as well as self-reported symptoms, function, and quality of life in communitydwelling adults with moderate to severe kneeOAand; 2, assess the feasibility of acommunity-based AQUATIC program forcommunitydwelling adults with knee OA. Methods: Seventeen volunteers (12women(x = 61. 1 years) and 5men(x = 69. 0 years)) participated in a progressive 8-10 week AQUATICEXERCISE program, consisting of 20-24, 1-hour sessions. Outcome measures, acquired twice before beginning the EXERCISE protocolas well as after 4 and 8 weeks of EXERCISE, included the Knee Injury and Osteoarthritis outcome score (KOOS) instrument, a 2 minutewalk test (2MWT), a 10 step stair climb for time, and an isometric knee extension strength assessment. Results: Significant improvements were detected in 2 MWT, 10 step stair climb, right quadriceps isometric force development, andthe KOOS symptoms and stiffness subscale. Significant improvement was found on KOOS function subscales between baseline testingsessions and maintained at follow-up. Non-significant improvements were identified in left quadriceps isometric force development, KOOS pain, and KOOS quality of life. Conclusions: These data suggest that a community-based, progressive AQUATIC EXERCISE program is feasible and results in measurableimprovements in function without worsening symptoms. Further study is warranted to investigate the impact of a longerprogram and the role of AQUATIC EXERCISE in the long-term management of patients with knee OA.

BACKGROUND: The appearance of a new innovation in medical science named AQUATIC EXERCISE has faded the effects of other preventive EXERCISEs in patients with multiple sclerosis to a large extent. Since EXERCISE is one of the beneficial factors in enhancement of quality of life, researchers decided to investigate the role of AQUATIC EXERCISE on the patients' quality of life.METHODS: This study is a semi experimental research that was performed on 22 patients chosen by simple random sampling. The standard SF-36 questionnaire was used and data was gathered by interview before and after AQUATIC EXERCISE. Data was analyzed by paired t test via SPSS software version 10.RESULTS: The mean ages of participants were 32.86 from all, 68.2% of participants were married and 45.5% of them were high school graduates. The paired t test showed the significant differences between different aspects of quality of life before and after AQUATIC EXERCISE.CONCLUSIONS: The findings of this research revealed that AQUATIC EXERCISE has enhanced the aspects of multiple sclerosis patients' quality of life; therefore the program of this EXERCISE is suggested to be used for the patients with multiple sclerosis along with other methods of treatment for improvement in quality of their lives.
