Abstract

〔目的〕本研究は，歩行分析における最適な加速度計装着部位を同定することを目的とした．〔対象〕健常成人男性15名とした．〔方法〕快適歩行にて鉛直・前後・左右成分の体幹加速度と床反力を同時に測定した．加速度計は第10胸椎（Th10），第3腰椎（L3），第2仙椎（S2）に装着した．左右下肢合成床反力と加速度より算出した床反力推定値との一致度の指標として，3つの装着部位での相互相関係数（CC）により比較した．〔結果〕鉛直・前後成分のCCはL3にて最も高く，左右成分のCCはいずれも低かった．〔結語〕歩行分析では加速度計をL3に装着することにより，鉛直・前後成分では実際の床反力に近似した波形パターンを得られることが示された．

Abstract

〔目的〕本研究は，背もたれの高さが安楽座位時の臀部ずれ力に及ぼす影響を検討することを目的として行った。〔対象〕対象は，健常成人男性13名（年齢：21.3±2.4歳）であった。〔方法〕床反力計を用いて座位時に臀部にかかるずれ力を測定した。形態学的な影響を考慮し，測定したずれ力を各対象者の体重で除した値を採用した。測定肢位は，床反力計上に殿部，床反力計外に下肢を置いた長座位とした。背もたれの代わりとして床反力計上に接しないように横方向に設置した平行棒にもたれさせた。実験は，背もたれ（平行棒）の高さを調節した2条件（床面から46 cmと49 cm）で行った。〔結果〕結果を背もたれ高別にみると，46 cmでは0.83±0.27 [N/kg]，49 cmでは0.71±0.25 [N/kg]であり，2条件間に有意差が認められた（p=0.014）。〔結語〕本研究結果から，背もたれの高さが高い方が臀部ずれ力は小さくなることが示された。

Abstract

[Purpose] This study was conducted to clarify the minimum detectable change (MDC), and the intra-day, inter-day, and intra-rater reliabilities of measurements of spinal curvature in the prone position with a Spinal Mouse. [Subjects] The subjects were 20 healthy adult males. [Method] Measurements were made twice on two separate days, and through the intra- and inter-day ICC, SEM, and MDC95, we investigated the intra-rater reliability. [Results] The intra-day ICC ranged from 0.85∼0.95, and the inter-day ICC ranged from 0.77∼0.91. The inter-day results suggest that changes in thoracic kyphosis, lumbar lordosis, and sacral inclination angles greater than 7.5, 4.0, and 4.8°, respectively, are true variations. [Conclusion] The results suggest that the measurement of spinal curvature in the prone position with the Spinal Mouse can be made with high reliability. [ABSTRACT FROM AUTHOR]
