  1. list 3 common current uses for hydrotherapy:
    • envrionment for therapeutic exercise
    • environment for health maintenance exercise
    • component of wound tx
  2. list the 7 physical properties of hydrotherapy:
    • high specific heat (4x air): holds heat energy
    • high conducitivity (25x air): transfers energy from body to water or vise versa
    • conduction
    • convection: both energy theories
    • buoyancy: weight off joints, NWB or WBAT
    • resistance: workout, pulling, kicking
    • hydrostatic pressure: compression, pressure on intersitial spaces, increased venous return
  3. force experienced as an upward thrust in opposite direction of gravity is called:
  4. who discovered that an immersed body part receives an upward thrus equal to weight of fluid it is displaced in:
  5. density of an object determines if it sinks or floats...determine skin or float for the following:

    when water has a specific gravity of 1.0
    salt water SG of 1.024:
    ice SG of .917:
    human body SG of .974:
    adipose SG of .85:
    • salt water SG of 1.024: human body will float more..
    • ice SG of .917: floats (ice cubes)
    • human body SG of .974:
    • adipose SG of .85: more buoyant
  6. list 4 characteristics of the physical proptery of resistance:
    • viscosity provides resistance to motion of a body in water
    • resistance increases in proportion to speed
    • effective rehab tool for strengthening due to varied resistance
    • variable resistance and pressure of moving water valuable for wound cleansing and debridement
  7. pressure exerted by a fluid on a body immersed in fluid is called:

    a depth of 4 ft. gives how much pressure:
    • hydrostatic pressure
    • a depth of 4 ft. gives how much pressure: 88.9 mmHg (22mmHg/ft) (enought pressure to over come gravity)

    • similar to effects of compression devices
    • promotes circulation and may help alleviate edema from venous or lymphatic insufficiency
    • facilitate CV fxn: more blood to/from heart, precaution CHF or PE
    • brace unstable joints
  8. the physiological effects of heat and cold are the same as in superficical thermal agent chapter lecture. describe the following:

    metabolic changes:
    modification in soft tissue extensibility:
    • hemodynamics: vasodilate (hot tub)/vasoconstrict (cool tub)
    • metabolic changes: increase (hot tub)/decrease cool tub
    • modificiation in soft tissue extensibility: stretch out, break collagen bodns
  9. list the 7 physiological effects of using hydrotherapy for cleansing effects (lavage):
    • softens materials and exerts pressure
    • component of wound care
    • hydration
    • debriding/friction effects on exudate and necrotic tissues
    • force of debridement dependant on flow rate
    • cleans all contours
    • antmicrobials and detergent
  10. a situation in which the area surrounding a wound retains too much moisture, thus causing it to turn white and soften is called:
    macerated wounds

    a contraindication of cleansing for hydrotherapy
  11. list the 5 physiological musculoskeletal effects of hydrotherapy:
    • unloads weight bearing structures
    • load sensitive joints
    • reduces effects of gravity
    • velocity dependent resistance
    • hydrostaic pressure to increase muscdle blood flow to 100-225% (increased O2 to muscles)
  12. 75% immersion or chest deep water decreases weight bearing by ~ 75 in LE structres

    waist deep:

    give an example of conditions/phase of rehab:
    • neck: ~100%
    • waist deep: ~ 50%

    example: 50% weightless environment= RUN IN WATER

  13. list the 7 physiological cardiovascular effects of hydrotherapy:
    • primarily due to hydrostatic pressure
    • pressure in distal extremities moves blood to trunk (up to 60% increase)
    • increases venous return
    • increased heart filling (up to 30%)
    • increased myocardial contraction
    • increase in stroke volume (decreased HR; beats less frequent for same blood flow)
    • increased cardiac output (inc. 30%)
  14. cardiovasclar effects

    how is HR effected for a given RPE vs land
    • reduced HR for given RPE (rate preceived exertion) vs land
    • does increase more if water is warm
    • HR is not a good indicator of work in water
    • RPE is higher for given HR in H20 than on land
  15. cariovascular effects

    how is oxygen consumption effected for a given RPE vs land:
    reduced oxygen consumption (VO2) for given RPE vs land
  16. list 5 physiological respiratory effects of hydrotherapy:
    • work of breathing increases in water: hydorstatic pressure against rib cage
    • decreased expriatory reserve volume 50%
    • decrease vital capacity 6-12%
    • increase work of breathing 60%
    • exercise induced asthma: high humidity, absences of pollen, hydorstatic pressure, hypoventiliation, peripheral vasoconstriction
  17. describe why respiratory distress is a contraindication for hydortherapy:
    already struggling to breath, so why put them in H2o to breath against resistance
  18. describe the physiological renal effects of hydrotherapy:
    • increases urine production: as well as sodium/potassium excretion
    • secondary to increased: renal BF and decreases in ADH
  19. list the 3 psychological effects of hydortherapy:
    • invigorating but relaxing
    • relieve anxiety
    • social
  20. list the 3 neurologic effects of clinical application:
    • proprioceptive input (especially with central deficits)
    • increased safety (explore area would not typically fxn in)
    • improved balance
  21. list the 3 clincial applications for hydrotherapy of cardiac fitness:
    • allows deconditioned to exercise
    • cardiac rehab
    • COPD pts
  22. list 3 contraindications of hydrotherapy:
    • maceration
    • bleeding
    • Dx CV disease
