The Force Generation in a Two-Joint Arm Model: Analysis of the Joint Torques in the Working Space.

Front Neurorobot 2018 23;12:77. Epub 2018 Nov 23.

Unit of the Theory of Sport and Motorics, Chair of Individual Sports, University of Physical Education and Sport, Gdańsk, Poland.

The two-segment model of the human arm is considered; the shoulder and elbow joint torques (JTs) are simulated, providing a slow, steady rotation of the force vector at any end-point of the horizontal working space. The sinusoidal waves describe the JTs, their periods coincide with that of the rotation, and phases are defined by the slopes of the correspondent lines from the joint axes to the end-point. Analysis of the JTs includes an application of the same discrete changes in one joint angle under fixation of the other one and vice versa; the JT pairs are compared for the "shoulder" and "elbow" end-point traces that pass under fixation of the elbow and shoulder angles, respectively.
