2. Bellwork
Remember how you felt after immersing your ankle in the cold whirlpool for a few minutes until it became numb. Now imagine that you could immerse your ankle in a warm whirlpool for a few minutes.
How long would it take for the numbness to wear off?
What would the ankle feel like?
Share your answers with a partner.

In which stage of healing would contrast bath be used? (hold up fingers)
1. Acute stage of injury 2. Sub-acute stage (48-72 hours) 3. Repair stage 4. Remodeling stage
1. Hand signals:
thumbs up or thumbs down to indicate agreement or disagreement
use fingers to indicate a number selection such as “Which is the correct solution one, two or three?”
teacher gives feedback to the students

8. Contrast Bath Therapy Most effective in the sub-acute stage
Primarily used for treating extremities
Fill one container with cold water (50 to 65°F)
Fill a second container with hot water (105 to 110°F)
Treat injury using a 3:1 ratio (3 minutes in heat, 1 minute in cold) or 4:1 ratio for about 20 minutes
Usually end with cold treatment

9. Contrast Bath Therapy (cont.)
Why use contrast bath therapy?
Changing from cold to heat causes a mild temperature increase
Temperature increase allows for increased blood flow to area (speed up healing without causing more swelling)
Still a popular theory, but no evidence that it actually works

Write on your Slates
List the physiological effects that happen when an individual is unable to exercise because of injury on your slates. Be prepared to share.
2. Whiteboards/Slates
student writes answer or solution to a question posed by the teacher
teacher solicits all students to show at the same time

11. Cryokinetics Used in acute stage of injury
Combines cryotherapy with exercise
Start w/ cold whirlpool, ice pack or ice massage to numb the body part (about minutes)
Begin exercise within pain tolerance (about 3-5 minutes)
Repeat cold water immersion and exercise 3 more times, ending with cold

12. Cryokinetics (cont.) Exercise should be active
Exercise should be pain-free
Exercise should be performed normally (without limping)
Exercise should progress in complexity and difficulty but stay within pain-free guidelines
