Abstract :
Background
We examined the feasibility and effectiveness of a community-based progressive aquatic exercise program for community dwelling 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 community dwelling adults with moderate to severe knee OA and; 2, assess the feasibility of a community-based aquatic program for community dwelling adults with knee OA.
Methods
Seventeen volunteers (12 women (x = 61.1 years) and 5 men (x = 69.0 years)) participated in a progressive 8 - 10 week aquatic exercise program, consisting of 20 - 24, 1-hour sessions. Outcome measures, acquired twice before beginning the exercise protocol as well as after 4 and 8 weeks of exercise, included the Knee Injury and Osteoarthritis outcome score (KOOS) instrument, a 2 minute walk 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, and the KOOS symptoms and stiffness subscale. Significant improvement was found on KOOS function subscales between baseline testing sessions 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 measurable improvements in function without worsening symptoms. Further study is warranted to investigate the impact of a longer program and the role of aquatic exercise in the long-term management of patients with knee OA.
