Patent ID: 7972285

Claim:
A motor function measuring sensor including a right hand sensor and a left hand sensor so as to measure motor function of fingers of a subject, each of the right hand sensor and the left hand sensor, comprising: a magnetic field generating unit for generating a magnetic field; a magnetic field detecting unit for detecting the magnetic field; a first holder to be attached to a first predetermined part of a living body for holding the magnetic field generating unit; a second holder to be attached to a second predetermined part of the living body for holding the magnetic field detecting unit, a distance between the first and second parts being variable by motion of the living body; and a sticking part, the magnetic field detecting unit outputting a measurement signal based on an intensity of the detected said magnetic field to detect a motor function of the living body, a distinguishing part for distinguishing the sensor to be used between the right hand and left hand of the living body, and an electric wire electrically connected to the magnetic field generating unit and the magnetic field detecting unit, wherein the electric wire has a connector unit including a plurality of pins as the distinguishing part and at least one of the first holder and the second holder includes an attachment surface, the sticking part detachably attaches the attachment surface to the living body, wherein there is a difference in a number of the pins between the right hand sensor and the left hand sensor.
