For the evaluation of pathological gait, a machine learning-based estimation vertical ground reaction force (vGRF) using low-cost insole is proposed as an alternative to costly plates. However, learning model for still relies on use plates, which not accessible in small clinics and individuals. Therefore, this paper presents plate-free from single leg stance (SLS) natural walking measured only by insoles. This method used linear least squares regression that fits measurements during SLS body...

本研究の目的は，車椅子のティルトおよびリクライニングの角度変化が殿部に生じる圧迫力および剪断力に与える影響を検証することとした。対象は健常成人12名とした。車椅子座面上に可搬型フォースプレートを設置し，殿部の圧迫力および剪断力を計測した。測定は6条件で行い，リクライニング0°ティルト0°（r0t0条件），リクライニング10（°r10条件），リクライニング20（°r20条件），リクライニング30（°r30条件），ティルト10（°t10条件），ティルト20（°t20条件）とした。各測定時間は5分間とした。圧迫力において，r0 t0条件に対してr10条件，r20条件，r30条件，t20条件は有意な低下，t20条件に対してr20条件，r30条件は有意な低下を認めた。剪断力において，r0t0条件に対してr10条件，r20条件，r30条件は前方剪断力の有意な増加，t10条件，t20条件は前方剪断力の有意な低下，t10条件に対してt20条件は後方剪断力の有意な増加を認めた（p＜0．05）。車椅子座位において圧迫力軽減にリクライニング，剪断力軽減にティルト10°の介入の有効性が示唆された。

Background: In Japan, children often suffer from locomotor disorders due to either too much or little physical activity. As a result, locomotive examinations have been incorporated into Japanese school education. However, the first stage of examination process is based on screening questionnaire by parents, which may lead serious oversights. Researchers discovered that considering results along with fitness tests can early detection in without overlooking them. Objectives: This study...
