Knee Osteoarthritis |
| Purpose: |
|
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.

| Study summary: |
|
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 and
SF-36),c) knee OA specific pain (KOOS pain) scores, and d) vastus lateralis muscle bulk
(thigh muscle). |
