Were you the one who asked about what type of water "tank" the PT shop had that I go to? If so, it is a HydroWorx and the model is "Rise". It has an underwater treadmill, a seat for seated exercises, plus lots of grab bars. It's a good way for me to get strong enough to go to a public pool to join the Mobility in Water class, which I attended regularly a few years ago. The tank challenges because of the resistance of the water and and the same time assists because of its bouyancy.
