Aquatic Power Training
Optimizing Mobility in Older Adults With Knee Osteoarthritis: Aquatic Power Training
調査の概要
詳細な説明
Aquatic based training can offer many of the same benefits associated with a land based exercises but water has certain properties that provide a more gentle and welcoming environment for exercising. Buoyancy in water counteracts gravity to support the weight of the subject and decrease the forces put on the joints. Viscosity of water can provide resistance proportional to the effort exerted and with gentle friction enhancing proprioceptive feedback. Immersing in warm water can cause an increase in body temperature due to specific heat and thermal conductivity, which can cause blood vessels to dilate. In addition, hydrostatic forces reduce edema, increasing venous return and healthy circulation. [Prins, 1999]; [Wilder, 1998]
Studies have shown that water based exercise has been proven to significantly decrease pain in people with knee osteoarthritis compared to those in a land based exercise program. [Silva, 2003] In comparing an aquatic physical therapy session to a no intervention group the aquatic program resulted in less pain, improved physical function, quality of life, and strength. [Hinman, 2007]
The purpose of this research study is to determine whether an aquatic therapy program aimed at increasing muscle power will be effective in improving knee symptoms and mobility in men and women with symptomatic knee osteoarthritis.
The purpose of this study is to assess the efficacy of aquatic power training for improving mobility limitations, disability and quality of life in older adults with symptomatic knee OA.
Hypothesis 1: In older adults with symptomatic knee OA, a 6-week aquatic power training intervention will reduce lower limb mobility limitations (400m walk time).
Hypothesis 2: In comparison to baseline measures, at 6-week follow-up, there will be improvements in a) lower limb function (LLFDI), b) quality of life (KOOS Knee QOL),c) knee OA specific pain (KOOS pain) scores, and d) vastus lateralis muscle bulk (thigh muscle). These changes will be sustained at 12 week follow-up.
