Aqua therapy – Natural Analgesic (Pain Killer) is an under-water treadmill at Adams Wylie Physio Rehab Centre that uses the natural properties of water, or the principles of relative density, buoyancy, hydrostatic pressure, surface tension, viscosity and resistance to achieve its therapeutic benefits in orthopaedic, neurological, geriatric, fitness and sports rehabilitation. Exercising in water can help reduce fatigue and pressure on joints, soothe aches, and help with balance. It can also improve mobility and flexibility, allowing patients to recover from an injury or a surgery. For athletes, the under-water treadmill provides an alternative method of training to maintain cardiovascular fitness without the weight bearing demands of land running.
