Development of isokinetic and iso-contractile exercise machine “MEM-MRB” using MR brake
2009
Strengthening muscle force by training, e.g., an isokinetic exercise is used widely used method in the rehabilitation medicine and sports medicine. However, many conventional isokinetic exercise machines cannot be used safely and easily. In this study, we developed an isokinetic and iso-contractile exercise machine, named “MEM-MRB”, using an “MR brake”. This brake includes MR fluid. Because of the rapid response of the MR fluid, the MR brake shows superior response performance compared with conventional brakes. In other words, a simple and safe training machine with accurate rotational speed can be realized with this brake. At the same time, a high-speed (900 [deg/s] at an elbow joint) control was realized with this machine. Additionally, we experimented in isokinetic and iso-contractile exercise.
