Quantitative assessment of human-exoskeleton integration through a neurophysiological marker of embodiment.

ABSTRACT: Assistive exoskeletons are increasingly used in rehabilitation settings, yet their adoption in real-world scenarios remains limited. This is partly due to the insufficient understanding of human-device interaction mechanisms. The process through which the central nervous system integrates external devices is known as "tool embodiment" and is primarily assessed through subjective questionnaires. This protocol aims to identify a quantitative marker of embodiment by leveraging the phenomenon of sensory attenuation, i.e., the modulation of sensory stimulation intensity perception as a function of action control. Twenty-one participants either self-administered electrical stimulation to the median nerve by stepping on a pedal or remained still during stimulation by the experimenter, in two cond
