简要总结
Knee Osteoarthritis (OA) accounts for a significant proportion of mobility limitations and is one of the most disabling problems facing the growing population of older adults. The purpose of this research is to reduce disablement of older adults with symptomatic knee osteoarthritis.
详细描述
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).
