Design of a controlled-energy-dissipation orthosis (CEDO) for functional suppression of intention tremors.

摘要: Conventional neurological practice is generally not successful in restoring independent upper extremity function to people with disabiling tremors. The authors have been investigating an orthotic approach, the application of energy-dissipating loads affected limbs, allow voluntary intent be expressed while attenuating tremor. CEDO 1 a prototype Controlled-Energy-Dissipation Orthosis, which permits 3 degrees freedom (dof) needed for table-top activities. It mounts user's chair or table and applies velocity-proportional resistance his/her forearm by means computer-controlled magnetic particle brakes. design incorporates stiff linkage transmission elbow brake orthosis, allowing it fixed frame reference. This eliminates its inertia from moving provides virtually direct drive all dof. Initial experimental results show selective clinically significant tremor reduction during tracking tasks.
