Procedure.

We first conducted a short semi-structured interview with the SCI participants about their SCI, related pain, and bodily sensations, followed by the CDS administration. Before the experiment started, the experimenter carefully defined the level above which each patient had intact tactile perception on the back to ascertain the detectability of tactile stimulations. All patients with SCI with neuropathic pain rated the intensity of current pain on the VAS (baseline). The VLI and FBI protocol were then carried out in a counterbalanced order across participants. After each experimental condition, the participants rated the current neuropathic pain (only SCI-pain), the VLI, or FBI questionnaire (all participants). The order of the VLI conditions was randomized across patients, and the order of the FBI conditions counterbalanced.
