We use a temperature controlled underwater treadmill for canine patients who can benefit from low-impact exercise or to help gain mobility and motor function in patients with neurological conditions.  Overweight and post-surgical patients can gain strength and movement using the buoyancy and resistance of the water.  The underwater treadmill is much more precise and controlled than open water swimming in which a patient can do more harm by the erratic movements used when swimming.  Patients seem to feel more comfortable in the underwater treadmill with their owners close by, cheering them on.
