Closed-Loop Control System for Postural Righting Post-Spinal Cord Injury

This study explores a closed-loop controller utilizing tilt sensor signals to trigger stimulation for postural righting post-spinal cord injury. Stimulation is activated below flexion threshold and stopped above upright threshold. The feasibility of this system was investigated and reported in the research article cited.

  1. Figure 2. Example of control signal from tilt sensor and thresholds used by controller to trigger stimulation. Stimulation is applied when control signal is below flexion threshold. Stimulation is ceased when control signal is above upright threshold. Note: Values on y-axes for all figures containing forward tilt are inverted to align with intuitive nature of movement. • Murphy JO, Audu ML, Lombardo LM, Foglyano KM, Triolo RJ.
