Aquatic Therapy Flashcards
What are the 3 Aquatic Principles?
1) Buoyancy
2) Hydrostatic Pressure
3) Resistance
What is buoyancy?
The upward thrust acting in the opposite direction to the force of gravity that allows a reduction in joint compression forces by being weightless
“A body immersed in a liquid, either wholly or partially, is buoyed up by a force equal to the _____ __ __ ____displaced by the body.”
weight of the liquid
4 benefits of the Buoyancy Principle
- Decreases weight bearing
- Decreases joint compression forces
- Decreases stress on connective tissues
- Decreases fear of falling
What is hydrostatic pressure?
The pressure exerted by a fluid at equilibrium due to the force of gravity
4 benefits of the Hydrostatic Principle
- Reduce Edema
- Improves circulation
- Evens tactile input
- Improves muscles of inspiration which assists with expiration
The faster you go the more resistance there is due to what?
The drag force
4 Benefits of resistance
- Improved tone
- Improved endurance
- Improved muscle balance
- Increased time to react- if notice “falling”
What is the ideal water temperature, air temperature, and humidity?
92 degrees
2-3 degrees warmer than the water
50%
7 Populations that benefit from “ideal” temperature
- Prenatal
- Obese
- MS
- Cardiac
- OA
- Fibromyalgia
- Pain
4 Physiological Benefits of Aquatic Therapy
1) Circulatory System
2) Pulmonary System
3) Musculoskeletal
4) Renal
How does aquatic therapy benefit the circulatory system?
Blood is displaced upward to the chest and into the heart (due to buoyancy) which increases blood flow
Central Blood Volume can improve by __%
60
Heart rate in water is __% lower than on land
15
How does aquatic therapy benefit the pulmonary system?
Vital capacity increases 10%
The total work of breathing increases 60%
Expiratory reserve volumes decrease 75%
