Device for measuring motor synergies of a pair of upper limbs or a pair of lower limbs

Abstract

The subject of the application is a device for measuring motor synergies of a pair of limbs, comprising a Scott bench or a bench with a backrest or a bench with a backrest integrated with an armrest, characterized in that it consists of two mounting beams - left (1a) and right, with at least one mounting point (2a) of the left beam (1a) and at least one mounting point of the right beam, to which a horizontal beam (4) is attached by means of a left (3a) and right vertical linear bearing with a lock, respectively, while on the horizontal beam (4) there are horizontal linear bearings with a lock and with at least a single-axis joint, left (5a) and right, to which at one end the left joint rod (6a) and the right joint rod are attached, respectively, while at the other end the left joint rod (6a) is connected to a strain sensor (7a) for the left limb, and the right joint rod is connected to a strain sensor for the right limb,wherein the strain sensor (7a) for the left limb is connected to one end of the left rod (8a) of the sensor, while the strain sensor for the right limb is connected to one end of the right rod of the sensor, while the other end of the left rod (8a) of the strain sensor (7a) for the left limb is connected to the left holder (9a), and the other end of the right rod of the strain sensor for the right limb is connected to the right holder, wherein the signal lines of the output of the strain sensor (7a) for the left limb are connected to the differential inputs of the signal amplifier of the strain sensor for the left limb, respectively, while the signal lines of the output of the strain sensor for the right limb are connected to the differential inputs of the signal amplifier of the strain sensor for the right limb, while the output of the signal amplifier of the strain sensor for the left limb is connected to the first input of the adder,while the output of the strain sensor signal amplifier for the right limb is connected to the second input of the adder, and the output of the adder is connected to the input block of the A / D converter module, while the output of the sensor signal amplifier for the left limb or the output of the sensor signal amplifier for the right limb is connected in parallel to the input block of the A / D converter module, while the output of the A / D converter module is connected to the input of the visualization module containing the screen (130).,
