Abstract: Provided is a compensatory movement source body region identification method including: a step of first determination that determines existence of the compensatory movement in a first motion based on whether or not first measurement data satisfies a first criterion; and/or a step of second determination that determines existence of the compensatory movement in a second motion that is of lower complicity than the first motion based on whether or not second measurement data satisfies a second criterion; and a step of identifying at least one or more body region to be the source for causing the compensatory movement based on whether or not third measurement data in a third motion that is of lower complicity than the second motion satisfies a third criterion, when determined in the step of first determination and/or the step of second determination that there is the compensatory movement.

Abstract: With respect to a pressing tool main body 10B of a pressing tool for a pelvic floor muscle group 1B, a convex upper surface has a hardness of 10 to 20, which is a value of the International Rubber Hardness Degree (IRHD) complying with JIS K 6253, when the pressing tool main body 10B is in an initial state in which the pressing tool main body 10B is subject to no external force and is not squashed, and has a hardness of 25 to 35, which is a value of the International Rubber Hardness Degree (IRHD) complying with JIS K 6253, when the pressing tool main body 10B is subject to an external force, and a height from a seat surface to the convex upper surface becomes a half of the height from the seat surface to the convex upper surface in the initial state.
