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 4/13/2019 Property of CTE Joint Venture
