METHOD FOR MONITORING THE EFFECT OF WEIGHTLESSNESS ON THE MOTOR ACTIVITY OF AN OPERATOR ON BOARD A SPACECRAFT Russian patent published in 2022 - IPC A61B5/103 B64G4/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely, to a method for monitoring 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. 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 space flight while the operator performs locomotor movements using the set position of the support surface relative to the operator, wherein the angles in the joints between the consecutively connected segments of the body of the operator are 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 values of biomechanical parameters are repeatedly measured over a set period of time while the operator performs locomotor movements, the biomechanical structure whereof is identical to the one recorder, using the set position of the support surface relative to the operator. Based on the measured values of biomechanical parameters and the measurement times, the predicted time intervals are determined, counted from the time of the last measurement, wherein the predicted values of said biomechanical parameters will reach the set critical values over said intervals. After a time since the last measurement not exceeding the minimum time from the determined predicted time intervals, said values of biomechanical parameters are re-measured 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.

EFFECT: increase in the accuracy of monitoring the effect of weightlessness on the biomechanics of movements of the operator due to the accuracy of determining the time of change in the values of biomechanical parameters characterising the effect of weightlessness on the biomechanics of movements of the operator in space flight.
