Aquatics and Hydrotherapy (Exam 3) Flashcards
Heating, cooling, debridement, pain relief, muscle relaxation, exercise.
Uses of Hydrotherapy
Whirlpools, swimming pools, contrast baths.
Froms of Hydrotherapy
An object will displace an amout of water equivalent to its mass.
Achimedes’ Principle
Used as a counterirritant
Temperature
Counterirritant effect, and debridement tool.
Agitation
Ability of an object to float or be suspended in water.
Buoyancy
3 States of Buoyancy
Positive, Neutral, Negative
Positive
Float on surface
Neutral
Suspend at mid-depth
Negative
Sinks to bottom
The deeper the object goes in the water the more pressure exerted upon it.
Pressure
Resistance to flow, depends on temperature and speed of object trying to penetrate water.
Viscosity
Ability of water to maintain contact between individual molecules.
Cohesion
Postural alignment, surface area submersed, bone weight in relation to muscle and fat. Fat is more buoyant. Vital capacity. More air volume in lungs more buoyant.
Factors affecting buoyancy
Indications for Hydrotherapy
Wound care, thermal affects (muscle spasm, swelling, pain), exercise, gait training, pain relief.
Contraindications for Hydrotherapy
Uncontrolled BP, upper respiratory infection, mental disorders, cardiac/pulmonary conditions, incontinent patients if uncatheterized, patients afraid of the water.
Contact between 2 surfaces. Warm water and cold hand = warm hand.
Conduction
Fluid or air moving across surface, need jets on or patient moving, heats or cools body, much faster than conduciton. Wind chill = rapidly extracts heat.
Convection
Decreased weightbearing, comfortable for patients afraid of falling, exercise option for weak extremites.
Advantages
Contamination, falling, skin irritant, supervision, drowning, suture or wounds require waterproof barrier.
