Features
Read full description

ステップエイドプラスは、履くだけで簡単に荷重測定やバランス確認の出来る歩行分析計です。 リハビリにおける歩行荷重が適正かどうかをリアルタイムに音でお知らせします。 適正荷重で歩行すると適正音「ピッピッピッ・・」、荷重が強すぎる際は警告音「ピピピピピ・・」、荷重が弱すぎる際は無音「・・・・」と被験者ご自身でも荷重の良否判断が可能です。 同時にグラフで荷重の様子を一目で確認できます。 また、4分割のセンサが静止・歩行時の両方で左右の足にかかる荷重、バランスを計測することで片足ごとの重心位置表示、および全身の重心バランス確認ができます。 靴型で場所を選びませんので効率的なリハビリテーションを実現いたします。 ※なお、使用時には医師や理学療法士の指導のもと行うようにお願いいたします。 その他の機能 ・荷重量の範囲指定が可能。 ・過去の測定データを閲覧することが可能。 ・測定データをCSV形式で出力可能。 本アプリの使用には、株式会社レイマックの歩行分析計「ステップエイドプラス」を購入していただく必要がございます。 ※なお、ステップエイドプラスは日本国内のみ使用可能です。
