Outline of Final Research Achievements

We showed that illusory kinesthesia by vibratory tendon stimulation as neurorehabilitation for a distal radius fracture reduces pain (Imai 2016). The purpose of this study was to examine the activate motor cortex of patients suffering from pain during illusory kinesthesia by vibratory tendon stimulation using EEG, and we investigated the relevance of motor cortex and post-operated pain to clarify analgesia mechanism. As a results, we showed it became clear that the activity of the bilateral sensorimotor area (C3, C4) was provided when I brought about an illusory kinesthesia by the tendon vibration stimulation after surgery of distal radius fracture next day with. In addition, we revealed that pain at rest and movement at pain was improved after intervention. A negative correlation was seen in the C3 and C4ch ERD value and the amount of change in pain at rest. These results suggest that sensorimotor areas activated by the illusory kinesthesia may be involved in pain relief.
