| Research Abstract |
Humans have highly developed sensory receptors and functions that allow them to survive and recognize various kinds of external information, and can regulate dynamic properties of their musculoskeletal systems to achieve specific physical goals. Such dynamic properties of human movements can be expressed by mechanical impedance parameters: stiffness, viscosity, and inertia. It suggests that the training in the regulation ability of human impedance would be effective for improving damaged motor functions of the physically challenged.
This study developed a new training methodology based on human mechanical impedance, so-called "Impedance Training method." The major achievements are as follows:
[1] The virtual sports system was developed by means of robotic and virtual technologies, and human impedance properties during training movements were examined quantitatively.
[2] Human regulation ability of muscle impedance properties and human perception ability of environmental impedance properties were investigated. Based on the experimental findings, human sensory-motor integration theory using mechanical impedance was proposed.
[3] A prototype system for the impedance training was developed with a couple of a liner motor table with one degree-of-freedom in which a various environmental impedance properties can be realized by a variable impedance control method. The effectiveness of the proposed training methodology was demonstrated with the cooperation of healthy volunteers.
