Outline of Final Research Achievements

Sensory attenuation refers to the phenomenon whereby the intensity of a sensation produced by self-generated movement is attenuated. Sensory attenuation is reduced in patients with schizophrenia and this reduction is correlated with delusional beliefs in otherwise healthy people. We are interested in patients whose dysfunctional body parts include not only the hands but also the lower limbs. Thus far, little is known about sensory attenuation in the lower limbs. We examined the sensory attenuation of a big toe and an index finger by using healthy subjects and soccor players. The result of the sensory attenuation of the big toe changed as a factor of increasing target force, and was slightly different from the control data. These data provide the new insight of taking a lower limb’s sensory attenuation into account using a force matching task.
