And how many stroke departments do you think have this? I'd say none except for this one. The hospital I was at gave up their pool years before.Useless because 10 or so people might be able to take advantage when there are 10 million yearly stroke survivors.
Aquatic treadmill walking may increase exercise capacity after stroke
For patients in rehabilitation
after a stroke, walking on an underwater treadmill produces better
measures of exercise performance compared to conventional treadmill
walking, reports a study in the American Journal of Physical Medicine & Rehabilitation.
"Aquatic
treadmill exercise may be a useful option for early intensive aerobic
exercise after subacute stroke, as it may both improve their aerobic
capacity and maximize functional recovery," according to the preliminary
research by Bo Ryun Kim, MD, PhD, and colleagues of Jeju National
University Hospital, Korea.The study included 21 patients recovering after a stroke—average time since their stroke was about two months. All patients had some walking ability, but with impaired leg movement on the side affected by the stroke.
The patients underwent two exercise tests: one on a conventional land treadmill and one on an aquatic treadmill, submerged in water up to their chests. In both tests, walking speed and slope were gradually increased until the patients felt they couldn't go any further. Measures of exercise capacity were compared between the two tests.Two key measures were higher on the aquatic treadmill test: maximal oxygen consumption (VO2max), reflecting heart and lung function during exercise; and metabolic equivalents (METs), reflecting energy use. Heart rate was not significantly different, but was significantly related to oxygen consumption on both tests.
Even though their exercise performance was higher on the water treadmill, patients felt they weren't working as hard as on the land treadmill, based on a measure called rating of perceived exertion. "This improved performance may reflect the fact that the aquatic treadmill exercise involved the fluid resistance of the water environment," Dr. Kim and colleagues write.
Regaining walking ability is a major challenge after a stroke. Because it's so difficult to walk, patients may be physically inactive, further their reducing exercise capacity. This suggests that early intensive aerobic exercise training might be beneficial in the early weeks after stroke. Treadmill walking is commonly recommended, but may be difficult or impossible because of decreased muscle power.
"The fact that the aquatic treadmill efficiently provides aerobic exercise without requiring full weight bearing means that it may be highly suitable for rehabilitation after stroke," according to the authors. The buoyancy provided by water reduces musculoskeletal impact while allowing combined aerobic and resistance exercise. Exercising in water also has the psychological benefit of freedom from the fear of falling.
The preliminary study is the first to explore the benefits of aquatic treadmill exercise for stroke patients. Further research will be needed to determine whether this approach leads to lasting improvements in exercise capacity and walking ability, several months after the stroke.
If so, then rehabilitation approaches including underwater treadmill exercise may help to overcome the low aerobic capacity seen in stroke survivors—which can contribute to decreased social activity and poor quality of life. Dr. Kim and colleagues conclude, "Aquatic treadmill exercise may not only improve baseline functional status and functional recovery during the subacute period, it may also enhance social participation and quality of life during the chronic stroke period."

Back when I was doing aquatic rehab.. (that was what really turned me around for moving and confidence) one of the things that they had was two underwater stationary bike. The rehab program was mainly people recovering from arthritis surgery, stroke and other movement disorders. The Canadian Arthritis society funded a study and gave the bikes. Pretty much the same research style and results as in the article. I think the bike was really good in that people were seated so not tipping over and felt more secure but muscles still had to work hard and had to be going up and down with no outward swing to the leg, and the foot needs to flex as you pedal. My perfect aquatic therapy pool would have both the bike and the treadmill, and lots of pool noodles
