 note = {足圧受容器の働きを知る目的で足底を冷却して足圧情報入力を減少させたときの静止立位時足圧中心動揺及び, 支持基底面の広さについて検討した。その結果足底の7分間の冷却により, 以下のように対照群との違いが認められた。1)静止立位時の足圧中心位置は有意に後方に位置していた。2)足圧中心動揺面積は有意な増加が認められた。3)クロステストでは前後方向で, 前方, 後方とも移動可能点が, 後方に位置していた。以上のことから, 足底からの圧情報は前後方向の位置の把握と身体動揺の大きな調節に関与していることが確認できた。 The purpose of this study was to know the function of mechanoreceptor in soles. Therefore, we cooled the soles at the temperature of - 150℃ to make them less sensitive with a use of synthetic cryo-air transpire (Nippon Sanso Co., Ltd.). Then Hirasawa's cross-test was used when the subjects stood on the gravicoder to measure the center of pressure at the soles and the base of support. The duration time when the cold air was applied to the soles was classified in three conditions as follows: A) Not cooled as control, B) cooled for five minutes, and C) cooled for seven minutes. The subjects were twenty healthy males. They were 19 to 29 years old with an average age of 21.4 years. Their mean height and weight were l71.6cm and 64.5kg, respectively. The results were as follows: l) With respect to the center of gravity in natural standing posture, the condition C) revealed the greatest backward displacement in fore-aft sway among all, then followed in order by conditions A) and B). 2) The sway area of condition C) was greater than other conditions and statistically significant. The distance of sway, however, revealed no significant differences among three conditions. 3) Cross-test in which the subjects could remain in standing posture in lateral movement revealed no significant differences among three conditions. However, the backward sway was significant in fore-aftward displacement. Through these results, following two findings can be stated: 1) The pressure sensation might affect fore-aftward displacement. 2) The pressure sensation might participate in low frequent ingredient of postural control., 金沢大学大学院医学系研究科活動能力回復学},
