| Outline of Final Research Achievements |
The aim of this study was to develop methods which can evaluate a sensory or motor dysfunction objectively, using magnetoencephalography (MEG), functional magnetic resonance imaging (fMRI), and other electrophysiological techniques. A new sensor device to monitor the acceleration and angular degree of finger motion, a tactile and pressure stimulator, and a system which can evaluate the
subjective degree of pain following electrical pain stimulation to skin in real time during MEG or fMRI measurements were developed and/or improved through this study. With the help of these appliances, we studied the MEG, fMRI, and motor-evoked potentials in patients with cervical spinal cord or peripheral nerve disorder. The availability and efficacy of the treatment methods which accompany these devices is clarified, by demonstrating how they objectively and non-invasively detect the extent of sensory or motor dysfunction.
