Aquatic Therapy Flashcards
Aquatic Principles (3)
- Buoyancy
- Hydrostatic Pressure
- Resistance
Buoyancy - def (3)
- The upward thrust acting in the opposite direction to the force of gravity
- The more deeply immersed you are in water, the less you weigh
- Allow a reduction in joint compression forces by being weightless
Archimedes Principle
A body immersed in a liquid, either wholly or partially, is buoyed up by a force equal to the weight of the liquid displaced by the body
Hydrostatic Pressure
The pressure exerted by a fluid at equilibrium due to the force of gravity
Benefits of Hydrostatic Principle
- Reduce edema
- Improves circulation
- Evens tactile input
- Improves muscles of inspiration; assists with expiration
Resistance - Viscosity/Drag forces
- Creates progression
- Stream line flow vs. turbulence
- Exercises in water should be performed faster to get more resistance
Benefits of Resistance
- Improved tone
- Improved endurance
- Improved muscle balance
- Increased time to react
What populations benefit from “ideal” temperature
- Prenatal
- Obese
- MS
- Cardiac
- OA
- Fibromyalgia
- Pain
Physiological Benefits of Aquatic Therapy (4)
- Circulatory System
- Pulmonary System
- Musculoskeletal
- Renal
- Other
Circulatory System effects
- Blood is displaced upward to the chest and into the heart
- Central Blood Volume can improve by 60%
- Cardiac volume increases
- Heart rate is 15% lower than on land
Pulmonary System Effects
- Vital Capacity decreases 10% when immersed to the neck
- The total work of breathing increases by 60%, expiratory reserve volumes decrease by 75% during neck immersion
Musculoskeletal System Effects
- Extracellular fluid is mobilized
- Reduces swelling more rapidly then bed rest; plus benefit of movement
- Muscles have increased blood supply
- Improved muscle relaxation
- Decreased joint compression
Renal System Effects
- Increased urine output
- Increased sodium loss
- Renal response increases with further immersion
Other Physiological Responses
- Body temperature changes
- Improved equilibrium due to righting reactions
- Over exertion
- Skin irritation
- Over stimulation of vestibular system
