FIELD: medical engineering. SUBSTANCE: method involves uprights with bars mounted on base having force sensitive and recording elements connected to each other with a lever and graduated with kg of force ticks. The force sensitive element has movable and fixed plate. The plates are set to allow bringing their planes close to and separating from each other. The fixed plate is mounted on bar ends on one side. The movable plate is connected to the fixed one by means of telescopic elements. Rod ends of the telescopic elements are connected to each other with a cross-bar carrying roller mounted on fork. The roller thrusts against short lever arm which axle is mounted between the bars. The long lever arm is articulated to movable protrusion of recording member. Casing of the recording element is connected to cantilever mounted on opposite ends of the bars movable and fixable by means of threaded rod with nut for adjusting tension force of recording spring. Movable plate is remote from the fixed one in initial state due to spring force of recording element. Deep flexor functions are determined by measuring pinching grip force of fingers. EFFECT: high accuracy of measurements. 2 cl, 4 dwg
