hydrotherapy Flashcards
what is hydrotherapy
the use of water for therapeutic purposes
What is thermo-hydrotherapy (warm water immersion)?
use of water at temps above the immersed body skin temp (> 93 deg F)
what is cryo-hydrotherapy (cold water immersion)?
use of water at temps below the immersed body skin temp (< 90 deg F)
what temp is the burn tank kept at?
93 deg (thermoneutral)
Indications of hydrotherapy?
- superficial cooling or heating
- wound care
- water exercise (NOT aquatic therapy)
- pain control
- edema control
3 advantages of hydrotherapy?
- provides perfect contact with skin (contoured areas)
- does not need to be fastened to the body
- allows movement during heating or cooling
Disadvantages of hydrotherapy when applied to extremities?
- distal extremity must be in dependent position
- may aggravate edema
What is important to consider for hydrotherapy
-edema counteracted by compression of hydrostatic pressure with immersion
specific heat
capacity to store heat
thermal conductivity
capacity of a substance to conduct heat
specific heat of water
4.19
specific heat and thermal conductivity of water is less or greater than air?
greater
physical properties of water?
- buoyancy
- resistance
- hydrostatic pressure
what is buoyancy
an anti-gravitational force or vertical upward thrust against gravity
what is an upward force on an object immersed in a fluid that is equal to the weight of the fluid it displaces, enabling it to float or to appear lighter
buoyancy
what does buoyancy promote
relative state of weightlessness
buoyancy is dependent on
- percent of body immersed
- specific gravity or weight density of the human body is less than water
Buoyancy on water helps to do what?
-decrease stress and compression on weight bearing structures
what is resistance-viscosity
a force counter to the direction of movement, controls flow of movement
resistance-viscosity increases with what
speed of motion and area of contact
a fast moving body results in what type of resistance
high
paddles and fins increase what
frontal area and increase resistance
slow moving body results in what type of resistance
moderate resistance
limbs straight in front does what
decrease frontal area and decrease resistance
what is hydrostatic pressure
the pressure exerted by a fluid on a body immersed in the fluid
pressure increases with what for hydrostatic pressure?
fluid depth
control over physical properties of water affects dosing and therapeutic goals by
hydrostatic pressure, buoyancy force, resistance
how hydrostatic pressure controls over physical properties of water affects dosing and therapeutic goals
increased or decreased by varying depth of immersion
how buoyancy controls over physical properties of water affects dosing and therapeutic goals
increased or decreased by varying % of body immersion
how resistance controls over physical properties of water affects dosing and therapeutic goals
- body movement velocity
- body surface area
- use of electrical turbine
benefits of mechanical properties of hydrotherapy
- enhances wound care
- enhances control of edema
- weightlessness effect
water pressure and turbulence force of turbines used for cleansing and debridement is used to enhance
wound care
Hydrostatic pressure causes limb compression and enhances
edema
what benefits body unloading and painful weight bearing that may occur on land
Weightlessness effect, Buoyancy
