Schematic of trunk feedback control system showing subject seated in work volume of motion capture cameras. Three computers – actuator computer, target and host manage the real-time environment for the tests. A linear actuator applied measured pull pulses to the chest of the subject. Settings for the tilt sensor are defined as OE for the upright threshold and OF for the flexion threshold.
