METHOD FOR DETERMINING THE EFFECT OF WEIGHTLESSNESS ON THE MOTOR ACTIVITY OF AN OPERATOR ON BOARD A SPACECRAFT Russian patent published in 2022 - IPC A61B5/103 B64G1/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely, to a method for determining the effect of weightlessness on the motor activity of an operator on board a spacecraft. Implementation of the method includes measuring the biomechanical parameters of motor activity of the operator, including the joint angles, in ground conditions. The values of the biomechanical parameters are compared. The effect of weightlessness on the biomechanics of movements of the operator is determined, accounting for the comparison results. Additionally, the biomechanical parameters of motor activity of the operator are measured in ground conditions while the operator performs locomotor movements using the set position of the support surface relative to the operator and to the interior. The angles in the joints between the consecutively connected segments of the body of the operator are therein measured starting from the segment nearest to the support surface, as well as the distance from the support surface to the endpoint of the segment of the body of the operator nearest to the support surface, the length of projection of movement of the endpoint of the segment of the body of the operator nearest to the support surface on the support surface, and the duration of said movement. The biomechanical structure of the locomotor movements performed by the operator is recorded, including the order and duration of intervals of movements, said angular, linear and temporal values of the biomechanical parameters are measured in space flight while the operator performs locomotor movements, the biomechanical structure whereof is identical to the one recorded, using the set position of the support surface relative to the operator. The result of the effect of weightlessness on the motor activity of the operator on board the spacecraft is determined based on the comparison of the values of biomechanical parameters determined in ground conditions and the values of the same values determined in space flight.

EFFECT: increase in the accuracy of determining the effect of weightlessness on the biomechanics of movements of the operator accounting for the primary ground and subsequent onboard measurements of the analysed values of biomechanical parameters.
