Abstract

本研究の目的は,高齢者を対象に歩行開始時の足圧中心点(以下,COP)の後方移動(以下,逆応答現象)を調べ,1)足指筋力,足関節背屈筋力,歩行開始前後の静的バランス能力との関連性を調べること,2)各パラメータの若年者との相違を調べ,高齢者における逆応答現象の移動距離が減少する要因を調べることである。中枢神経疾患の既往の無い,在宅生活を送っている自立歩行可能な高齢者15名を対象とした。計測パラメータは,(1)逆応答現象の前後方向最大距離:As,(2)逆応答現象の左右方向最大距離:Al,(3)歩行前静止立位バランス:Bd,(4)歩行後静止立位バランス:Ad,(5)逆応答出現までの潜時:Cd,(6)足指最大圧縮力体重比:Fg,(7)足指圧縮力の増加の傾き:Gs,(8)足指圧縮力発生までの潜時:Gd,(9)足指圧縮力発生から最大圧縮力までの時間:Tp,(10)足関節背屈トルク体重比:Dtとした。AsとAlに強い正の相関が認められた。AlとBdに負の相関が認められた。CdとGdに正の相関が認められた。若年者群との比較では,高齢者群はGsが有意に低かった。転倒群に対し運動療法を施行するとAl,Gsの増大,Bd,Gdの短縮が認められた。今回の調査では,高齢者の逆応答現象に関与する因子の明確化には至らなかった。

The relationship between the Inverse fluctuation of the center of pressure (COP) at gait initiation and toe muscle power, dorsiflexion power of ankle, static balance was studied among the elderly. The COP of the foot pattern during gait initiation has been well described as initially moving backward towards swing foot. Although this basic process is uniform regardless of age, the Inverse fluctuation of the COP tends to be small in the elderly. The purposes of this study were to clarify the COP during gait initiation among the elderly and related factors determining the COP. The first part of this study measured the following parameters of 15 eldely subjects. The parameters were 1) inverse fluctuation of sagital direction of the COP (As), 2) inverse fluctuation of lateral direction of the COP (A1), 3) the quiet-standing balance (Bd, Ad), 4) premotor time of the inverse fluctuation of the COP (Cd), 5) toe muscle power (Fg), 6) grip force slope (Gs), 7) pre-motor duration of the grip (Gd), 8) motor duration of the grip (Tp), and 9) dorsiflexion power of ankle (Dt). In the second part, the results were compared with those of five young subjects.
