define hydrodynamics

Back 1

how to use the physical properties of water to reach functional goals

Front 2

buoyancy

Back 2

an UPWARD force acting in the opp dir of gravity

Front 3

what does force in water equal to

Back 3

the weight of the volume of the displaced water

Front 4

what is the relative density or specific gravity of water

Back 4

1.0

Front 5

what happen if the RD is lesser than 1

Back 5

it'll float

Front 6

what is the RD of human body with inflated lung

Back 6

Front 7

what is the RD of lean body mass

Back 7

1.1

Front 8

RD of adipose tissue

Back 8

.90

Front 9

what is center of buoyancy and what is it for human

Back 9

center of gravity of the displaced fluid; T2-T4

Front 10

what is center of Gravity for human

Back 10

Front 11

name the three type of buoyancy exercises:

Back 11

buoyancy supported exercise; buoyancy assisted exercise; buoyancy resisted exercise

Front 12

which water exercise is equal to gravity minimized and it's effect and how it moves

Back 12

buoyancy supported exercise; pain relief; early movement; movement perpendicular to the water surface

Front 13

which water exercise is equal to active assisted exercise and it's effect; how it moves

Back 13

buoyancy assisted exercise; increase rom, early strenghening, mm re-education; movement upward toward the surface

Front 14

which water exercise is equal to resisted exercise and how it moves

Back 14

buoyancy resisted exercise; move down, opposing the buoyancy.

Front 15

how can you adjust the buoyancy resisted exercise

Back 15

increase surface area, speed, effort, equipment, flotation can also increase resistance.

Front 16

disadvantage of buoyancy resisted exercise

Back 16

max effort is required for max benefit

Front 17

what is the effect of buoyancy on weight bearing

Back 17

upward force of buoyancy reduce the effects of weight bearing and loading forces

Front 18

approximate the levels of reduction in water in standing at ASIS, Chest, and neck

Back 18

depth at ASIS= 50%
depth at chest= 75%
depth at neck= 95%

Front 19

what is hydrostatic pressure

Back 19

any pressure exerted by fluid on a body at rest

Front 20

FACT: more assistance/resistance is felt near the surface of the water

Back 20

FACT: longer lever arm provides more assistance/resistance

Front 21

FACT: Floating device may be used to alter assistance/resistance by moving the center of buoyancy

Back 21

FACT: with body weight reduced, mobility is increased

Front 22

up to what level of body will buoyancy have no more effect on body weight/weight bearing

Back 22

up to the depth of C7

Front 23

what is the effect of increasing depth

Back 23

increase pressure

Front 24

what is the effect of increase pressure

Back 24

centralization of peripheral blood flow; Starling reflex (HRxSV=CO), centralization increases CO without corresponding increase in HR (increase pressure help squeeze out the blood w/o extra effort from pt)

Front 25

what does HIP stands for and what does it mean?

Back 25

hydrostatic indifference point (located at the height of the DIAPHRAM; the depth at which hydrostatic pressure on the LE and abdomen is equal to the hydrostatic pressure of the water.

Front 26

why is HIP important

Back 26

it's important for pt with cardiac problem. Even though their HR will not increase, their CO will and we won't know that.

Front 27

what can deeper immersion do?

Back 27

cause centralization> inc CO w/o inc HR; can cause dec HR;
>can reduce swelling
>increase diuresis (dehydration)
>caution deep immersion for those with chest expansion problems (vital capacity must be at least 1500 cm3)

Front 28

what is fluid dynamics; what are they

Back 28

forces of fluid that contribute to resistance and movement; viscosity, turbulence, drag/draft

Front 29

what is viscosity

Back 29

internal friction between molecules, causing resistance to flow

Front 30

what is the relationship between force and viscosity

Back 30

more physical force increase viscosity; inc temperature decrease force

Front 31

turbulence

Back 31

the interrupted flow of molecules

Front 32

factors effecting turbulence

Back 32

resistance/speed (direct); sz and shape; pressure differentiation (higher in front); streamlining

Front 33

what is drag result of

Back 33

result of pressure differentiation

Front 34

what is drafing used for?

Back 34

use as an assistive or resistive tool, depending on whether the pt is in the front (resistive) or behind (assistive)

Front 35

what is the resistance of water in comparison to air

Back 35

12-15x more resistance

Front 36

what can water do for the postural mm and balance mechanics

Back 36

pressure differentiation and turbulent flow

Front 37

what are the precautions to water aerobics

Back 37

cardiac condition, extreme high BP, respiratory prob/COPD/lim capacity, diabetes (poor circulation), MS (work better in cooler water), recently healed wounds, absent or impaired peripheral sensation, incontinence, fear of water, pool chemical sensitivity, any precaution to land based exercise that is mitigated (lessen) by water

Front 38

contraindications to aquatic exercises

Back 38

open wound (unless covered by bio-occlusive dressing), skin disorders, contagious skin disease, untreated UTI, respiratory tract infection, uncontrolled seizure, fever, cardiac instability, excessive fear of water, gastrostomy, tracheotomy, any precaution to land based exercise that is mitigated (lessen) by water

Front 39

how to ensure safety in water

Back 39

proper screening of individuals, be alert of medical conditions, have lifeguard on site

Front 40

requirement for integration of water and land based exercises

Back 40

PT have a thorough knowledge of water, constant reevaluation and reexamination, avoid duplication of exercises between the two
