The invention relates to a respiration-based disease detection system for animals, which measures, by means of electronic pressure sensors, the vacuum effect generated by animals during respiration, evaluates said measurements, analyzes the magnitude and frequency of the force applied to the diaphragm, assesses the muscular strength of the diaphragm, and provides an output based on said assessment.

This invention provides a finger-operated device that offers a moderate sense of control through magnetic force, while also utilizing the slack in the string to achieve a feel that can be adjusted to the user's muscle strength and preferences. [Solution] The finger operating tool 10 of the present invention includes a plurality of beads 20 having through holes 22 and a plurality of magnets 30 arranged on their circumferential surfaces, and a non-annular string-like member 40 having both ends, which is inserted through the through holes of the plurality of beads and connects the plurality of beads in a series, wherein the plurality of beads can attract each other by the magnetic force of the magnets, the length L40 of the string-like member is longer than the sum of the lengths (L20) of the through holes 22 (beads 20) when the plurality of beads are arranged in the closest possible position to each other (L20 × number of beads 20), and has play S that allows relative movement or rotation of the beads, and both ends have retainers to prevent the beads from falling out.

To provide a muscle force estimation device and a muscle force estimation method capable of estimating muscle forces of individual muscle groups classified by function in a lower thigh part.SOLUTION: The muscle force estimation device causes a subject to exert end forces in four directions in a two-dimension plane, and measures the end forces exerted in the respective directions by a detection unit. The end force exerting position is estimated based on the measured end force and the moment around the z-axis orthogonal to the two-dimension plane detected by the detection unit when the end force is measured. Each measured end force is converted into a joint torque based on the estimated end force exerting position. On the basis of the converted joint torque, the output distribution of the hexagonal joint torque in which the lengths of all opposite sides are equal is plotted on a torque plane with the joint torque relating to the knee joint as one axis and the joint torque relating to the foot joint as the other axis perpendicular to the one axis. Based on the output distribution drawn by the drawing unit, the muscle group torque of each muscle group of the crus is estimated.SELECTED DRAWING: Figure 5

The application provides a muscle state monitoring method and a sensor, the method adopts a sensor which can be directly attached to the skin surface of the muscle, and collects a voltage signal generated due to muscle deformation. Through a set of effective wave peak identification rules, the number of wave peaks, peak-to-peak values and waveform characteristics in the signal are analyzed, and the direct detection of the muscle micro-force state is realized. Further, the application also provides a method for realizing gesture recognition, muscle strength limit determination and muscle fatigue degree grading based on the same sensor. The application solves the problems in the prior art, such as indirect detection, single function dimension, lack of quantitative rules for signal analysis and the like, and has the advantages of direct and accurate detection, multi-dimensional integrated evaluation, strong anti-interference ability, comfortable wearing and no hindrance to movement.

The present invention relates to a composition comprising a recombinant KAI1 protein that promotes muscle differentiation and exhibits muscle damage protection and muscle regeneration effects. Recombinant KAI1 has been found to increase the expression of genes and proteins of myogenic regulatory factors through activation of Akt / AMPK signaling pathways in myoblasts, promote myotube formation, induce differentiation from stem cells into myoblasts, improve muscle strength and muscular endurance in in vitro and in vivo muscular atrophy models through muscle damage recovery, and exhibit muscle damage protection and muscle regeneration ability, and thus is provided as a composition for muscle differentiation or as a composition for treating muscle damage, muscular atrophy, and sarcopenia.
