Abstract
The invention relates to a measuring instrument for detecting muscular activity (F) especially in the area of the hand. The measuring instrument (1) comprises an elongated connecting part (2), by which at least two points of the hand (6) moving with respect to one another are supported so that the movement of these points is transferred to the connecting part, a hand-securing means (12), and a measuring transducer (3, 13) secured to the connecting part for providing a signal dependent on the movement between the said points of the hand and preferably proportional to this movement, which signal can be transferred to the device (10) providing the measuring results. The connecting part (2) comprises two branches (4a and 4b) which together form an angle (5) and are connected to one another in an articulated (9) manner so that the angle (5) between the branches forms a plane (20) which remains at least approximately constant. The first branch (4a) is supported by one finger (7) and the second branch (4b) is supported by a part (8) of the hand with respect to which the said finger moves, in this case the forefinger. A force measuring transducer (3) is placed to measure the force respecti…
