In an in-vivo signal source detection method, three electrodes are arranged on the circumference of a surface of an living body to surround multiple muscle fibers; a first voltage Vgenerated when a first external resistor is connected to between each electrode and a ground potential and a second voltage V'generated when a second external resistor is connected to between each electrode and the ground potential; and a ratio V/V&#x2032;is calculated from the first voltage Vand the second voltage V&#x2032;, and the position of a signal source in the living body is detected based on three ratios V/V&#x2032;.

A method for detecting a position of a signal source in a living body includes: arranging three electrodes on a surface of the living body and alternately connecting a first external resistance and a second external resistance in parallel between the electrodes and a ground potential; measuring first voltages V(i=1, 2, 3) generated at the respective electrodes when the first external resistance is connected in parallel between the electrodes and the ground potential, and second voltages V(i=1, 2, 3) generated at the respective electrodes when the second external resistance is connected in parallel between the electrodes and the ground potential; and calculating three ratios V/V'(i=1, 2, 3) from the first and second voltages Vand V&#x2032;, and detecting the position of the signal source in the living body based on the three ratios V/V&#x2032;(i=1, 2, 3).

A sock is provided having a first compression areawhich raises the compressive force in a wale direction from a position A behind the toe area of a sole portion of the sock to a position C which includes the boundary between an arch portion B and a heel portion, a second compression areaprovided on the periphery to raise the compressive force in a course direction at the position A behind the toe area, a third compression areaprovided on the periphery to raise the compressive force in a course direction at an ankle portion D, and a fourth compression areaprovided on the periphery to raise the compressive force in a course direction from the position C which includes the boundary between the arch portion B and the heel portionto a position E at the base of the instep portion. The advantageous effect of protecting and restoring the shape of the longitudinal plantar arch is produced by the various compression areas, thereby stabilizing the position of the various compression areas while the sock is worn.
