I'm a long time Aikidoist (5th dan) and also practice Tai chi, after a serious spinal illness a couple of years ago, I rehabilitated myself using tai chi (and physical therapy too...) and developed an interest in this general field. I also recently became certified in one of the medical rehab forms of Tai Chi....
after doing some research I've realized that no one (that I've been able to find) has used Aikido movements in this way, and so, seeing how the doctors that developed the therapeutic short forms for Tai Chi (altering the movements for safety reasons, especially re: turning, knees and ankles etc...) did so, I've crafted a similar system using Aikido movements.
I'd love to talk to any doctors, neurologists of other health professionals about this, especially anyone who might know something about how to get this system tested in studies to verify that it has the same "evidence based" benefits as the Tai Chi based programs etc...
