Comparison of the Reaction Time Measurement System for Evaluating Robot Assisted Activities

RAA (Robot Assisted Activities) allow people to feel joy and pleasure and recover through contact with a robot. Considerable research has reported that RAA is useful for elderly persons, children hospitalized in pediatric wards and so on. However no specific evaluation method concerning RAA has yet been established. In this paper, we propose a reaction time measurement system for evaluating RAA. The level of caution or concentration of a subject can be estimated in terms of the reaction time based on visual or acoustic stimuli. We try to evaluate RAA using the variance in the reaction time before and after RAA respectively. We have developed a reaction time measurement system with hardware, following which we compared several reaction time measurement systems concerning performance and operability. We reported the results of comparisons featuring such measurement systems and the basic results of the RAA evaluation experiment using reaction time measurement. The results suggested that selection of the optimal enforcement form in RAA has been enabled through application of this reaction time measurement system.

The Clinical Effectiveness of JSS-H for the Short Term Prediction of Gait Ability in the Patients with Femoral Neck Fracture

〔目的〕大腿骨頸部骨折例の短期的な歩行予後予測において，日本脳卒中学会による脳卒中高次脳機能スケール（JSS-H）の臨床的有用性を検討した。〔対象〕大腿骨頸部骨折受傷者59例とした。〔方法〕重回帰分析を用い，術後3週目の歩行能力に影響を与える術後1週目の評価項目とその影響の強さを調べた。〔結果〕JSS-Hと健側大腿四頭筋筋力が3週目の歩行に影響を与える有意な因子として抽出され，標準偏回帰係数はそれぞれ-0.446，0.429となった。〔結語〕大腿骨頸部骨折術後の短期的な予後予測にJSS-Hは有用であり，術後評価では身体機能評価にJSS-Hを加えることでより適切な理学療法プログラムの立案が可能であると考えられた。
