The present invention proposes a walking disorder support apparatus and a walking disorder support method capable of detecting an onset of a gait disorder associated with motor symptoms in advance and performing motion assist. When a sign of a gait disorder associated with a motor symptom of a wearer is detected based on a correlation between a gait period and the rate of decrease of the gait period relative to the previous walk, and a sign of a gait disorder is detected The driving unit controls the driving unit so that the driving unit applies assist power to the wearer's knee joint. On the other hand, if no sign of gait disturbance is detected, the driving torque generated by the driving unit inhibits the walking operation of the wearer. The drive unit is controlled so as not to occur.【課題】運動症状に伴う歩行障害の発現予兆を事前に検出し、動作アシストを行い得る歩行障害支援装置及び歩行障害支援方法を提案する。【解決手段】歩行周期と直前の歩行に対する歩行周期の減少率との相関関係に基づいて、装着者の運動症状に伴う歩行障害の発現予兆を検出し、歩行障害の発現予兆が検出された場合、装着者の膝関節に対して駆動部がアシスト動力を付与するように当該駆動部を制御する一方、歩行障害の発現予兆が検出されない場合、駆動部による駆動トルクが装着者の歩行動作を阻害しないように当該駆動部を制御するようにした。
