【発明の属する技術分野】
本発明は、脳卒中などで歩行機能に障害を生じた患者に対して用いる歩行訓練装置、特に分回し歩行を矯正する分回し歩行防止装置に関するものである。
【0002】
【従来の技術】
脳卒中片麻痺の患者などは、尖足や短縮による左右の下肢長差のために分回し歩行を生じやすい。リハビリテーションにおける歩行訓練では、理学療法士が患者の後ろや横について、適正な歩行ができるように患者に指示を与えていた。従来技術において、分回し歩行の矯正を目的とした装置はないが、いわゆるモーションキャプチャーとして歩行などの動作解析を行うシステムを用いて、分回し歩行などの異常歩行を観察し、矯正するシステムを構築することは可能である(例えば、特許文献1参照)。
【0003】
【特許文献1】特開平9−276348号公報
【0004】
【発明が解決しようとする課題】
しかしながら、上記従来の動作解析装置においては、測定対象とする人を限られたスペースに置く必要があり、また正確に動作を把握するにはカメラを8台から10台ほど配置し、かなり大掛かりなシステムとなる。
本発明は、上記課題を解決するためになされたものであって、複雑なシステムを用いることなく、簡単な構成で容易に分回し歩行を矯正することができる分回し歩行防止装置を提供することを目的とする。
【0005】
【課題を解決するための手段】
上記課題を解決するために、請求項1の発明に係る分回し歩行防止装置は、患者の下肢に装着するベルト部と、脚を振り出す位置あるいは位置を時間微分した量を検知するセンサ部と、該脚の振り出しに関する情報を患者に知らせる情報提示部を備えるものである。
上記手段により、脚の振り出しに関する情報を患者自身が把握することができるため、簡単な構成で、容易に分回し歩行を矯正することができる。
また、請求項2の発明は、請求項1記載の分回し歩行防止装置において、情報提示部は、脚の振り出し方向の情報に患者の矢状面の方向と前額面方向の運動を計測情報として用いるものである。
上記手段により、振り出しの方向をより正確に把握しながら簡単な構成で、容易に分回し歩行を矯正することができる。
請求項3の発明は、請求項2または3に記載の分回し歩行防止装置において、ベルト部およびセンサ部を下肢以外の部位に装着したものである。

[第1実施例]
本発明の第1実施例に係る分回し歩行防止装置について、図1に基づいて説明する。
図1は、本発明の第1実施例による分回し歩行装置の構成を示すものであって、(a)はその正面図、(b)は上面図である。
図1において、101はベルト部、102はセンサ部、103は情報提示部である。
すなわち、図1に示すように、患側下肢に取り付けるベルト部101と脚を振り出す位置、あるいは位置を時間微分した量として速度や加速度などを検知するセンサ部102と、前記脚の振り出し方向を患者に知らせる情報提示部103を装置内部に配置する。センサ部102は、いわゆる加速度ピックアップなどを用いる。たとえば本装置を下肢の側面に配置すれば、前額面方向の速度Vxの大きさを検知できる。センサ部102から出力される電圧は情報提示部102に印加され、たとえば音声発生器などを駆動し、前額面方向の速度Vxの大きさに応じて音声の大きさを調節して、患者に振り出し方向の情報を知らせる。音声はいわゆるビープ音や人の声でもよく、「もっと膝を曲げて下さい」など運動を直接指示するものであってもよい。
本発明の第1実施例によれば、脚の振り出しにおける前額面方向の速度の大きさを患者自身が把握することができるため、簡単な構成で、容易に分回し歩行を矯正することができる。
[第2実施例]
本発明の第2実施例に係る分回し歩行防止装置について図1と図2に基づいて説明する。
図2は、本発明の第2実施例による分回し歩行装置の構成を示すものであって、(a)はその正面図、(b)は上面図である。
すなわち、図2に示すように、センサ部201において前額面方向の速度Vxだけでなく、矢状面の方向の速度Vyも検知できるように、図1のセンサ部102を2つ用い、速度を検知する方向が直交するように組合せてセンサ部201とする。本装置を下肢の側面か前面に沿うように装着し、検知した前記Vx、Vyをセンサ部201においてtan-1(Vy/Vx)を演算して、電圧値として情報提示部103に出力する。
本発明の第2実施例によれば、振り出しの方向をより正確に把握しながら簡単な構成で、容易に分回し歩行を矯正することができる。

本発明の第3実施例によれば、装置を取り付ける向きを限定する必要がなくなる。
なお、本実施例では装置を脚の側面に装着することとしたが、脚の振り出しに関する任意の情報を患者に提示してよく、前額面に限定するものではない。また、提示する情報は速度に限らず時間で積分・微分したものでもよい。
【0007】
