Hydrotherapy/Massage Flashcards
Buoyancy
tendency to remain afloat in liquid
Archimede’s principle
an object immersed in water experiences an upward thrust equal to the weight of the water displaced
Upwards vs downard movements
upwards movement are assisted
downward movements are resisted
Specific gravity of water
1.00g/cm2 at 4 celsius
less than 1 will float
greater than 1 will sink
Hydrostatic pressure
pressure exerted by the water on the immersed part
Pascal’s Law
object immsersed in a fluid will exert equal pressure on all surfaces of the object
Viscosity
degree to which fluid resists flow due to cohesive forces
viscosity resist movements in all direction\
Rapid movements vs Slow movements
rapid movement met with greater resistance
slower movement met with slower resistance
Physio effect of hydrotherapy: Cleansing effect
treatment of open wounds
soften/remove debris
debriding agent to remove endogenous agents
cleansing agent, microbial/surfactants can be added
Physio effect of hydrotherapy: Musculo effect
Decreased WB
strengthening
slowed bone density loss
less fat loss than with other forms of exercise
Physio effect of hydrotherapy: Cardiovascular effect
Increased venous circulation, cardiac volume, cardiac output
decreased HR, SBP, VO2 response to exercise
Physio effect of hydrotherapy: Respiratory effect
decreased vital capacity, exercise induced asthma
increased work of breathing
Physio effect of hydrotherapy: Renal effect
diuresis
increased sodium/potassium excretion
Psychological effects
relaxation
invigoration
Indications for Hydro therapy: subacute/chronic
decreased swelling (pressure) hastens healing (thermal) dec pain (thermal) inc ROM (thermal) inc strength (pressure)
Indications for Hydrotherapy: contractures/scars
relaxation (psychological)
inc soft tissue extensibility (thermal)
softens scar tissue (fluidity/thermal)
Indications for Hydrotherapy: arthritis
inc ROM (thermal)buoyancy dec pain (thermal)buoyancy
Indications for Hydrotherapy: open wounds
cleans/debride (fluidity/pressure) increases circulation (thermal/pressure)
