Description
このような場合も、神経や筋肉に異常がなければ外部刺激によって筋肉を動かすことが可能である。
この原理は外部から電気的に運動神経を刺激することで、手や足を動かすことにより、運動機能を回復するものである。
電気刺激法によって大きな筋収縮を得るためには、強い電気刺激を必要とする。この現象は感電と同じなので電気ショックによる不快感や痛みを伴う。ショックを少なくするために周波数や波形を改良するなど様々な研究が行われてきたが、電気的な刺激によって大きな筋収縮を実現することは困難な状況にある。
(1)本発明の磁気刺激リハビリテーション装置は、
患者の手2の各指につける反射器3と、
前記反射器3を介して指の変位を検出するセンサ1と、
患者の手首2に密着させて設置され、磁気パルスによって手首を動かす筋肉或いは指を動かす筋肉の少なくともいずれか一方の末梢神経を刺激する磁気刺激コイル7と、
磁気刺激コイル7に磁気パルスを発生させるパルス電流を供給するパルス電源6と、
パルス電源6を作動させるトリガ信号を出力するトリガ回路5と、
センサ1で検出した信号を分析して反射器3の位置を三次元座標として検出し、いずれかの指に設置された反射器3の動きが設定値を超えるとトリガ回路5にトリガ信号を発生させ、前記トリガ信号にてパルス電源6を作動させるパーソナルコンピュータ4とで構成されたことを特徴とする。
(2)請求項1記載の磁気刺激リハビリテーション装置において、
パーソナルコンピュータ4は、患者自身の意思と努力により、反射器3の「部位」で表されるいずれかの指を動かす筋肉に発生したわずかな自発運動の「方向」および「強さ」を反射器3の動きから演算し、自発運動の「部位」で表される(指)と当該指の関節運動の方向及び当該指の関節運動の強さに対応する1乃至複数のトリガ信号をトリガ回路5に発生させる機能を有することを特徴とする。
(3)請求項1又は2に記載の磁気刺激リハビリテーション装置は、自発運動検出手段として、光学センサを用いる。
(4)請求項1〜3のいずれかに記載の磁気刺激リハビリテーション装置のパーソナルコンピュータ4は、指毎に異なるトリガー信号の種類に応じて、磁気刺激パルスの強度、反復回数を変えて、筋肉の運動或いは神経の刺激を制御するようにトリガ回路5を制御する機能を有することを特徴とする。
(5)請求項1〜4のいずれかに記載の磁気刺激リハビリテーション装置のパーソナルコンピュータ4は、磁気刺激の反復時間が1ミリ秒から100ミリ秒の範囲で設定可能な機能を有することを特徴とする。
