Isokinetic exercises used in rehabilitation to strengthen muscles often require expensive exercise equipment. The safe isokinetic exercise system we developed uses only brakes with electrorheological (ER) or magnetorheological (MR) functional fluid. Rapid fluid response gives this equipment good response and control. In the sections that follow, we give basic isokinetic exercise concepts using an MR fluid brake, focusing on high-speed control of 900 deg/s at the elbow. We also suggest a new training mode we call isocontraction exercise.
