Lecture 4 - Aquatic Physio

Question 1

What are the 4 benefits of aquatic physio

Answer 1

reduction in swelling
buoyance - decrease WB
Heat - pain relief, relaxation
Different environment for patients - motivation

Question 2

What effect does hydrostatic pressure have on the body

Answer 2

“central hypervolemia”

• Increased venous return
• increased SV
• increased CO

Question 3

true of false: the thorax is less dense then the legs

Answer 3

true - legs are high in muscle, therefore, higher density

Question 4

What are the percentages of WB at C7, xiphoid process, ASIS

Answer 4

10%
33%
50%

Question 5

At what level is postural control challenged in aquatic physio

Answer 5

deeper than t11 - less WB and feedback from gravity, so the feed-fwd movement of the head and arms will have big impact on postural control

Question 6

define drag

Answer 6

viscosity of liquid and turbulence

Question 7

How do you increase Drag and turbulence

Answer 7

Increase SA of limb

Increase speed of movement

Question 8

What do you need to screen a patient for before commencing aqautic physio

Answer 8

CV risks - increased SV, HR, Co
respiratory risks - decreased lung volumes 
seizure in water - aspiration 
renal changes
cognitive impairments 
mobility restrictions

Question 9

What water temperature is ideal for women who are pregnant

Answer 9

<35 degrees is safe

30-32 for exercise

Question 10

what type of exercise can you perform in aquatic physio

Answer 10

ROM 
CV - CO is increased and lung vols decreased from being immersed
Strength
functional strenght 
walking

Question 11

what did Orselli/durant find the difference in speed was between land and water

Answer 11

comfortable walking speed is 2.7x slower than on land
