Outline of Final Research Achievements

Using electronic-engineering technology, a PC-connected pegboard for automatic and precise detection of individual peg insertion and pull-out moments was developed in the first study.This permitted separate evaluation of peg manipulation time from hand reaching time. In order to verify it usefulness, data were obtained from 50 healthy young adults, and 20 elderly adults (>68 yrs) who performed simple fast peg transfer tasks between the holes of 4 different distances with the use of right and left hands. In addition, data were also gathered for a peg reverse-transfer task under a short hole-to-hole distance condition.The effects of hand dominance, transfer distance, gender,and age were statistically tested.In the second study, a peg equipped with grip and lift force measurement system was developed, which was tested using 8 healthy young subjects.The results confirmed it usefulness of the force information in detailed examination of peg manipulation.

Academic Significance and Societal Importance of the Research Achievements

光センサーをペグボードに内装させ、センサー信号をデジタル化してPC内に取り込むことで、一本一本のペグを操作するのに要する時間と次に動かすペグへのリーチングの時間データを完全に分離して、さらにミリ秒単位での正確な計測を可能にした。また、本研究で開発した力センサー装備のペグも、ペグ操作時の把握力と持ち上げ力を詳細に調べることを可能にした。また本研究では、それらについて健常青年と高齢者の基礎データを呈示することも成し遂げた。正確な時間や力データを提供できるセンサー内装型ペグボードは、リハビリテーションや職業適性訓練、神経生理学研究での手指の巧緻性機能を正確に評価する上で有用なツールとして期待できる。
