CCAT CCAT Aquatic Therapy and Hydrotherapy 1 — Questions and Answers
Question 1: Which property of water most directly reduces weight-bearing stress on joints during underwater treadmill therapy?
- Viscosity
- Buoyancy (Correct answer)
- Hydrostatic pressure
- Surface tension
Correct answer: Buoyancy
Buoyancy counteracts gravity, reducing the effective body weight and joint loading during aquatic exercise.
Question 2: At what water level (relative to the dog's body) does underwater treadmill therapy typically offload approximately 60% of body weight?
- Carpus level
- Elbow level
- Greater trochanter level (Correct answer)
- Shoulder level
Correct answer: Greater trochanter level
Water immersion at the level of the greater trochanter offloads roughly 60% of body weight, making it ideal for early post-operative gait retraining.
Question 3: Hydrostatic pressure in aquatic therapy primarily benefits patients by:
- Increasing core temperature
- Reducing edema and improving circulation (Correct answer)
- Stimulating muscle hypertrophy
- Decreasing proprioceptive input
Correct answer: Reducing edema and improving circulation
Hydrostatic pressure exerts uniform compressive force on tissues, aiding lymphatic and venous return to reduce swelling.
Question 4: Which water temperature range is most commonly recommended for canine hydrotherapy to promote muscle relaxation and pain relief?
- 55–65°F (13–18°C)
- 70–75°F (21–24°C)
- 80–92°F (27–33°C) (Correct answer)
- 98–104°F (37–40°C)
Correct answer: 80–92°F (27–33°C)
Warm water between 80–92°F promotes vasodilation, reduces muscle spasm, and enhances comfort without causing heat stress.
Question 5: A primary contraindication for underwater treadmill therapy in canine patients is:
- Mild hip dysplasia
- Open wounds or unhealed surgical incisions (Correct answer)
- Decreased muscle mass
- Chronic arthritis
Correct answer: Open wounds or unhealed surgical incisions
Open wounds or unhealed incisions risk infection and tissue maceration when submerged, making aquatic therapy contraindicated until healing is complete.
Question 6: The viscosity of water compared to air provides which therapeutic benefit during aquatic exercise?
- Reduces cardiovascular demand
- Provides resistance in all planes of movement (Correct answer)
- Lowers body temperature
- Eliminates proprioceptive feedback
Correct answer: Provides resistance in all planes of movement
Water's viscosity creates multidirectional resistance with every movement, allowing muscle strengthening without the need for additional weights.
