Hydrotherapy can benefit rehabilitation by which property?

• A. Increases joint load
• B. Buoyancy supports body weight
• C. Reduces exercise options
• D. Decreases blood circulation

Answer: (B)

Buoyancy reducing the effective body weight is what makes hydrotherapy beneficial for rehabilitation. When you’re immersed, water pushes upward, unloading joints and supporting a portion of your weight. This means movements are easier to perform with less pain and lower risk of further injury, allowing early range-of-motion exercises and gentle strengthening to progress safely.

This doesn’t align with increasing joint load, which would hinder rehab. It also isn’t about reducing exercise options—the aquatic setting often expands what you can do by enabling movements that are hard on land. And hydrotherapy actually helps circulation through hydrostatic pressure, not decreases it, aiding swelling reduction and healing.
