Description
角度−トルク特性図において、全施行の屈曲相の全データポイントのうち関節角度が10°〜110°の範囲を抽出し、その回帰直線を求めた。そして回帰直線の傾きを動的屈曲相のバネ係数と定義した。動的伸展相のバネ係数も同様に定義した。
角度−トルク特性図において、ある一つの関節角度における屈曲相の全施行のトルクの平均値を動的屈曲相のバイアスと定義した。動的伸展相のバイアスも同様に定義した。動的屈曲相のバイアスと動的伸展相のバイアスとの差をバイアス差と定義した。30°、60°、90°の3つの関節角度についてバイアス差を計算し、それらの和をバイアス差の和と定義した。
最大屈曲相(最大屈曲位静止時)と最大伸展相(最大伸展位静止時)のそれぞれの表面筋電図波形を2.5Hzのローパスフィルターを用いて整流平滑化した。次いで、整流平滑化した筋電図波形の1秒間における積分値(Integrated EMG=IEMG)を計算した。上腕二頭筋のIEMG比を、(上腕二頭筋のIEMG比)=(最大伸展相におけるIEMG)/(最大屈曲相におけるIEMG)と定義した。上腕三頭筋のIEMG比を、(上腕三頭筋のIEMG比)=(最大屈曲相におけるIEMG)/(最大伸展相におけるIEMG)と定義した。IEMG比は、筋が受動的に伸展された状態での筋電活動の強さを示す特徴量である。上腕二頭筋及び上腕三頭筋のそれぞれについて、IEMG比を求めた。
