| Outline of Final Research Achievements |
Hand function is affected by neurological disturbance such as a stroke. We hypothesized that the changes in blood flow of the finger during concentrated finger perception reflect the severity of sensory impairment. To identify this hypothesis, we measured finger skin blood flow (FSBF) during Braille reading performed under the blind condition and tactile-pressure threshold in stroke patients. The tactile-pressure threshold showed a significant difference between the affected and unaffected hand. FSBF was decreased during Braille reading. However, the responses of FSBF observed at the affected side were much greater than those seen at the unaffected side (affected side: -11±9%, unaffected side: -5±10%). Moreover, a significant relationship was observed between the change in FSBF and tactile-pressure threshold (r = -0.44). These findings suggest that the modulation of finger skin blood flow during a tactile discrimination task is related to sensory impairment after stroke.
