1. What is the definition of hydrotherapy?
    application of water, internally or externally for treatment of physical dysfunction
  2. What are 5 effects hydrotherapy has on body tissue?
    • 1.thermal-cold/hot
    • 2.mechanical-movement/turbulence
    • 3.debridement of wounds
    • 4.pain relief
    • 5.relaxation of muscles
  3. What type of water to neuro patients tend to relax in?
    cool water
  4. What methods of heat transfer happen thru hydrotherapy?
    • convection
    • conduction
  5. What is the law of refraction?
    • limbs arent where they appear to be
    • bending of light
  6. What law states fluid pressure is exerted equally on all surfaces of rest at a given depth?
    • pascals law of hydrostatic pressure
    • the deeper in the water you go, the more pressure is exerted
  7. What is a upward thrust force on a body part in water?
  8. What is newtons law of cooling?
    rate of cooling a person in a given time is proportional to difference in temp between environment and the body...

    get out og hydrotank and even though the body is warm you feel cold
  9. What is the specific gravity of water? Do you float/sink at higher/lower?
    specific gravity of water is 1

    • float <1
    • sink >1
  10. What is the archimedes principle?
    • when a body is partly or entirely immersed in fluid, at rest, it experiences and upward thrust equal to weight of fluid at rest...
    • water rises up
  11. What is friction that occurs between molecules of a liquidand causes resistance to the liquid flow?

    water has low viscosity, which allows for fast movements
  12. What is an irregular flow of fluid that increases resistance at higher speeds of movement?
  13. What are some physiological effects of warm water?
    • vasodilation
    • decreased bp, hr
    • increased venous and lymphatic pressure (pascal)
    • increased local metabolism, blood flow
    • decreased sensitivity to nerve endings
    • increased pain threshold, collagen elasticity
  14. What are some mechanical effects of hydrotherapy?
    • mechanical stimulation to skin receptors
    • counter irritant-gate control theory
    • debridement of wounds
    • massaging action
    • supportive medium for exercise
  15. What are some indications?
    • cleansing/hygiene
    • decrease weight bearing
    • strengthening
    • cardiac effects (strengthens cardiovascular and pulmonary systems)
    • debridement of wounds
    • deliver/take away heat
    • pain control
    • edema control
  16. What are some contraindications?
    • maceration of a wound (skin gets wet, spongy and whiteish....wearing a bandaid while doing dishes)
    • bleeding/hemorrhaging
    • full body immersion - cant use if theres cardiac insufficiency/instability, infection, incontinence, epilepsy
  17. If you have a thick nasty wound what should you do while using hydrotherapy?
    place aggitator directly at the wound until it gets normal skin/pinkish then turn aggitator away
  18. What are some precautions?
    • impaired sensation
    • infection
    • pt is confused
    • recent skin grafts (watch temp and aggitator)
    • pregnancy
    • certain diseases (MS)
  19. What is the temp range for cold water, and what is it used for?
    • 0-26 C
    • 32-79 F

    acute inflammation (lightning victim). neuro patients, control tone in hypertonic pts
  20. What is the temp range for tepid water, and what is it used for?
    • 26-33 C
    • 79-92 F

    normal aquatic exercise temp, acute inflammation if colder temp isnt tolerated
  21. What is the temp range for neutral warmth and whats it used for?
    • 33-35.5 C
    • 92-96 F

    open wounds, medically compromised patients with circulatory, sensory, or cardiac disorders, decreased tone (hypotonic pts)
  22. What is the temp range for mild warmth and whats it used for?
    • 35.5-37 C
    • 96-98 F

    increase mobility in burn patients
  23. What is the temp range for hot and whats it for?
    • 37-40 C
    • 99-104 F

    control pain
  24. What is the temp range for very hot and whats it for?
    • 40-43 C
    • 104-110 F

    increase soft tissue extensibility, chronic conditions, limited body area only
  25. What are some type of whirlpool tanks?
    • portable (you can push it around)
    • fixed (permanent fixture somewhere)
    • extremity (use for LE/UE)
    • high boy (extremity tank, but taller)
    • low boy (looks like big bathtub..sit and extend legs)
    • hubbard tank (full body immersion)
    • walking tank (pt can walk inside..underwater treadmill)
  26. What are the equipment parts of a whirlpool?
    • tank..stainless steel
    • water
    • mixture control valve
    • turbine
    • thermometer
    • drain
    • seats
  27. What should you document when using a whirlpool?
    • type of tank
    • temp
    • time
    • exercises performed inside
    • how it was tolerated
    • additives
    • ROM/function increase/decrease
