Aquatic Therapy Flashcards
definition: determines if an object will float
ratio of the weight of the object to the weight of an equal volume of water
relative density
Do males or females have a higher relative density?
males
definition: force acting in the opposite direction of gravity
buoyancy
definition: When a body is fully or partially submerged in a fluid at rest, it experiences an upward thrust equal to the weight of the fluid displaced
archimedes principle
Spastic extremities (float/sink) with buoyancy.
sink
Buoyancy creates (decreased/increased) proprioceptive input for patients
decreased
definition: The pressure exerted by the molecules of a fluid upon an immersed body; equal pressure everywhere
hydrostatic pressure
definition: fluid pressure is exerted equally on all surfaces on an immersed body at a given depth
pascal’s law
Hydrostatic pressure (decreases/increases) edema
decreases
Hydrostatic pressure (increases/decreases) tactile defensiveness
decreases
(true/false) hydrostatic pressure assists with respiration
true
(true/false) Hydrostatic pressure decreases anxiety.
false
What is the ideal range of temperature for exercise?
82-84 degrees
> 88 degrees for arthritis
definition: the bending of a ray of light as it moves from one medium into another medium of a different density
refraction
Refraction can cause extremities to appear __% larger and ___% closer to surface of water than they really are
25%, 25%
definition: The friction between molecules of liquid which cause resistance to flow as the molecules adhere to each other and the surface of the body moving through it
viscosity
Resistance of viscosity drops to ___ when force stops.
0
definition: continuous steady movement of a fluid
streamlined/ laminar flow
definition: irregular movement of fluid with movement varying at any fixed point
turbulent flow
(true/false) turbulence increases proprioceptive feedback
true
Physiologic effects of exercise in the water depends on the patient’s ____.
posture
Aquatic therapy (increases/decreases) RR and blood supply to muscles
increases
Aquatic therapy (increases/decreases) muscle metabolism and HR
increases
Aquatic therapy has a (increased/decreased) CV demand
increased (con of aquatic therapy)
