ストレスフリー療法は，体表の特定の部位に遠赤外線照射による温熱刺激を加えることにより，末梢の血流が増加するなどが期待できる．ストレスフリー療法を効果的に行うために，足部F点を正しく刺激することが求められる．そこで本報告では，足部F点を正確に固定するための固定具を開発することを目的とした．足部の骨格構造の特性を得るために6名の対象者の計測を行った．計測は，スマートフォンによる足部の表面形状の計測システムを用いて，踵，内果などの6点を特徴量とした3次元の座標データを取得した．この座標データから6つの評価指標を構築し，固定具の設計データとした．
計測結果に基づき，編んだサポータータイプの固定具を試作した．固定具をすべての対象者についてオーダメイドで作成することも考えられるが，価格と簡便性の観点から，特定のサイズ別のタイプを用意し，足部F点の正確な部位の特定と固定性を高められるよう，位置決定は個別に行う方がよいと考えられた．サイズの種類は計測結果に基づき設定すべきと思料された．
Stress-free therapy is the application of thermal stimulation by far-infrared radiation to specific areas of the body surface, which is expected to increase peripheral blood flow. In order to effectively carry out Stress Free therapy, proper stimulation of the feet F point is required. The objective of this report was the development of a fixation device to secure the feet F point. Measurements were conducted on 6 subjects to obtain information on characteristics of the foot skeletal structure. The measurements were performed by a system using smartphones to measure the surface shape of the foot region, which obtained 3-dimensional coordinate data for 6 points, including the heel and medial malleolus, as feature values. Six evaluation indicators were then constructed from the coordinate data, and used as data for development of the fixation device.
Based on the measurement results, a prototype supporter-type device was produced by weaving. Although it is conceivable that these devices may be custom made, from the viewpoints of price and convenience it was considered favorable to prepare different types depending on characteristics, and to determine their positioning individually while increasing the degree to which they can secure the feet F point. It is presumed that the design specifications for types by size will be organized according to the measurement results.
