 note = {application/pdf, 本研究は身体左側の非利き手手首，胸部，腰部，足首の活動を同時記録する多部位アクチグラフの基礎資料の提供を目的とした。記録は高齢者男性1名を対象に正常な日常生活の下で連続7日間実施した。アクチグラフの時系列データの分析により，活動水準に有意な部位差を認めたが，部位に共通して約24時間周期のサーカディアンリズム，日中の行動内容の差異および睡眠状態を特徴づける活動傾向が明らかになった。測定部位の一致率と相関および総活動量の分布に基づいて，粗体動の信号を検出するために活性部位数と活動水準の臨界点を設定した。粗体動の信号は入出眠の難易と中途覚醒の頻発を含む睡眠日誌に対応する出現傾向を示した。多部位アクチグラフによる覚醒と睡眠へのアプローチの有用性について考察した。
This pilot study aimed at providing the basic data of multi-actigraph which simultaneously measured the activity of the four left sites of the body: non-dominant wrist, chest, lumbus and ankle. Recordings were made for 7 consecutive days in one healthy elderly male under normal daily life. Analyses of time series data revealed the common trends of activity to the four sites, indicating circadian rhythm of around 24h cycle, differences in daytime behavioral contents and sleep state, although their levels of activity significantly differed. On the basis of concordance rate, correlation of activity between sites, and distribution of total activity, the critical points for both the activity counts and active sites were set to detect the signals of gross body movements (GBMs). Appearances of GBMs during sleep showed a tendency to correspond to the sleep log which contained difficulty in falling asleep and frequent awakenings after sleep onset. The helpfulness of multi-actigraphic approach to wakefulness and sleep was discussed.},
