found this while on my way to compete in the collegiate state championship regatta in Saratota FL, representing the UF varsity womens crew team. we did really well and i had fun on the way there. i have actually participated in some research studies on parkinsons disease. they had me walk on a split treadmill with one leg walking at a slow rate and the other leg walking at a faster rate. i sure did look funny when i stepped off the treadmill!
