下肢麻痺感覚フィードバック重心動揺超音波素子

项目摘要

本研究課題を通じてヒトの起立時の姿勢の制御特性にかんする新しい知見[1,2]が得られた.これを元に姿勢動揺に関する感覚フィードバック装置の基本部分である,姿勢の安定性を計測する新しい装置の試作[3]を行った.1.ヒトの起立時の重心位置の同定に関する知見:自然な起立静止時においても不随意な姿勢の動揺が生じ,その大きさは両足を結ぶ方向に1cm,これに直交する方向に2cm程度であった.2.両足による指示領域の同定に関する知見:前後左右斜めの8方向に意図的な重心の移動を生じさせたところ,立位姿勢を維持できる荷重の支持領域は,両足の左右への開き方や前後の関係に関わらず,足部の骨格(第一中足骨骨頭,外足縦アーチ,踵骨骨底)に沿った範囲となる.以上の知見から,姿勢の動揺を計測する装置の使用として,測定範囲(重心の水平方向の移動範囲を一辺40cm以上の正方形領域内に想定)と測定精度(1cm程度)を決定した.重心と両足の相対的な位置を同定する装置の試作:ヒトの起立時の姿勢の安定性を超音波素子を用いて直接的に測定する装置を提案・試作した.臨床的な実用性を考慮して小型・軽量などの条件を加味した.装置の性能評価を行い,測定範囲を満足するが,測定精度は不足していることが示された.以上のように,生態工学・リハビリテーション工学の分野においてユニークで実用的な研究成果が得られた.これらは4件の研究発表を通じて報告された.今後は,静止時ばかりでなくヒトの歩行中など動的な条件下での姿勢動揺を詳細に調べる必要がある.また,試作装置の測定精度を向上しなければならない.

The purpose of this study is to understand the characteristics of posture control when you stand up. The basic part of the device is very important, and the stability of the new device is in an attempt to do [3]. The position of the center of gravity is the same as the position of the center of gravity when you stand up. It is known that when you stand up and rest naturally, you do not move your posture at will, and when you stand up, you do not move randomly. The direction of your feet is 1cm, and the direction of your cross is 2cm. 2. The left and right sides of the leg indicate that the field is the same as it is known that the center of gravity of the front and back slant in the direction of 8 is moved, the position is maintained and the load is supported in the field, the left and right sides of the foot are closed in front and back, and the bone of the foot (the first middle foot bone, the external foot, the base of the calcaneus) is closed along the range. The above information is given, and the attitude measurement device uses the instrument to determine the range (the horizontal movement range of the center of gravity, the range of movement in the square field of more than one 40cm), the accuracy of measurement (the degree of 1cm), and determine the range. The position of the center of gravity is the same as the setting device: the posture is stable when you stand up. The supersonic element is used to directly measure the position of the device. Test the usability of the bed, measure the size of the bed, add flavor to the bed. The performance of the device, the range of the measurement, the accuracy of the measurement, and the accuracy of the measurement are not enough. In the case of ecological engineering, there is a distinction between ecological engineering and engineering. There are 4 research forms, general reports and reports. In the future, when you are still, you are not allowed to do so under the condition that you are moving in the line. Make the device to measure the accuracy up and down.
