Research Abstract

The mechanism of the intelligent orthosis in this research is to add six sensors and four actuators to an ordinary orthosis for the active control of knee motion. It was confirmed the error of 6-DOF measurement by the trial machine was little in a walking motion. However, it was not successful that the actuators became smaller to put out sufficient power for control.
The influence of static external force on the relative position between tibia and femur was reserched by using an open-type MRI to confirm the effect of the intelligent orthosis in vivo. It was found the motion of the instant center was depend on the external load. We made some softwares for each disease and examine to select the effective parameters to treat in dynamic condition such as a walking.
We researched the application of mechatronics functon to prevent the overload to tissue in orthopaedics and rehabilitation. Since CPM (Continuous Passive Motion) using in rehabilitation after orthopaedic surgery sometimes causes excessive stress in the diseased tissue, the application of this mechanism of the intellient orthosis hardware is expected to give the motion by the individual program of 5 axes control.
The clinical effectiveness of the mechanism of the intelligent orthosis was practically confirmed. A basic dsign of the small actuator is required for completion of the intelligent orthosis.
