| Outline of Final Research Achievements |
The recovery function of somatosensory evoked magnetic fields was recorded to investigate excitatory and inhibitory balance in the somatosensory cortex of patients with carpal tunnel syndrome. Distances on the vertical axis between the equivalent current dipoles for the first and third digits were shorter in patients than in control participants. The root mean square for the N20m recovered earlier in patients compared to controls; this was statistically significant at an interstimulus interval of 10 ms. Coherence value was analyzed in the measurement population including carpal tunnel syndrome, complex regional pain syndrome patients, and healthy subjects. Coherence value showed significant differences between these patients and healthy controls.
