PROBLEM TO BE SOLVED: To solve problems for example, a prior method of walking evaluation using an accelerator, has not been practically used in a level in which quantitative evaluation useful in a medical field, can be performed.SOLUTION: A walking evaluation device comprises: an accelerator attached to a waist side part of a subject, and measures acceleration degree in an advance direction of the subject； a frequency analyzer for analyzing an output of the accelerator by frequency analysis； and a controller for reading a component of a pace basic frequency as PSD1, from an output of the frequency analyzer, then reading a frequency component which is 1/2 of the pace basic frequency as PSD0.5, then calculating PSD0.5/PSD1.SELECTED DRAWING: Figure 1【課題】従来の加速度計を用いた歩行評価の手法は、医療分野で有用な定量評価を行えるほどの実用化には至っていなかった。【解決手段】被験者の腰側部に取り付け、前被験者の進行方向への加速度を計測する加速度計と、 前記加速度計の出力を周波数分析する周波数分析器と、 前記周波数分析器の出力から歩調基本周波数の成分をＰＳＤ１として読み出し、前記歩調基本周波数の１／２の周波数成分をＰＳＤ０．５として読み出し、ＰＳＤ０．５／ＰＳＤ１を算出する制御器を有することを特徴とする歩行評価装置。【選択図】図１
