A challenge of decoding movement intention from intracortical electrodes is that the signals change over time — thus, intracortical BCIs have required frequent interruptions for decoder recalibration. (sciencedaily.com)
Key to this work is a new approach that allows the user to voluntarily control the exoskeleton movements to yield more natural, intuitive and flexible ambulation by basing stride — the length and height of steps — on movement intention signaled by hands and fingers. (KesslerFoundation.org)
This recalibration is typically performed using a special task in which the participant tries to move the cursor to prescribed targets so that movement intentions can be mapped to the new neural activity patterns. (sciencedaily.com)
