Hydrotherapy Flashcards
Hydrotherapy comes from what words
Hydro - water
therapeia - healing
Enumerate physical properties of water
Specific heat and thermal conductivity
Buoyancy
Resistance
Hydrostatic Pressure
amt of energy that we need to inc temp of a given weight of a material by a given no. of degrees
specific heat
unit of specific heat
joules per gram per deg.
– ability of one material to transfer the heat via conduction
thermal conductivity
unit of thermal conductivity
(cal/sec)/ (C/cm)

temperature to use for acute inflammation
cool
temp for exercise, acute inflammation if cant tolerate cold
tepid
temp for open wounds, medically-compromised pts, decrease tone
neutral warmth
temp to increase mobility of burns
mild warmth
temp for pain control
hot
temp to increase tissue extensibility, chronic conditions
very hot
temp that should not be used
> 43C or >110 F
principles of buoyancy
Archimedes’ principle
Specific gravity
principle that states when a body is immersed in fluid at rest, it creates an upward thrust equal to the amount of fluid displaced
Archimedes’ principle
corresponds to density of material: density of water ratio
specific gravity
formula of density
mass/ volume
Specific gravity of pure water
1
Specific gravity of salt water
1.024
Specific gravity of ice
0.917
specific gravity of air
0.00121
specific gravity of average human body
0.974
specific gravity of subcutaneous fat
0.85
relation of specific gravity to pure water
greater than 1 - sink
less than 1- float
higher sog
easier to float like salt water
