| Outline of Final Research Achievements |
The purpose of our study was to investigate the relationship between reflex function related to vestibular system and gait performance among patients with a post-stroke hemiparesis. As a result, a decrease in vestibulo-ocular reflex function post-stroke has an effect on gait performance in response to changing task demands. Regarding to rehabilitation tools, vestibular information focus on training could improve both the vestibulo-ocular reflex and gait performance in post-stroke patients. On the other hand, motor dysfunction of the hemiplegic lower extremity might lead to inhibition of normal standing postural stability. Decreased reflex function related to vestibular system could directly cause stranding postural instability during vestibular stimulation.

本研究は，末梢前庭障害患者や眩暈症状がなくても中枢神経障害によって前庭覚が関わる反射機能及び姿勢安定性が低下することを明らかにした．さらに，前庭覚に焦点を当てたトレーニングは前庭反射機能や応用的な歩行能力を改善する可能性を示した．これは転倒危険性が高い脳卒中患者に対して，前庭覚に着目した反射機能および身体機能評価の重要性を示すとともに，前庭リハビリテーションが転倒を予防するための一助となり得る可能性を明らかにした．
