Abstract: Chronic pain is a significant concern for many individuals with spinal cord injury (SCI). However, few effective treatments have been found for SCI-related pain. The current study sought to explore whether persons with SCI-related pain would respond to hypnotic suggestion for pain relief, and to examine possible moderators of this response. Twenty-two individuals with SCI-related pain rated their 6-month average and least pain on 0–10 scales of pain intensity. They also rated their current pain intensity and pain unpleasantness on 0–10 scales at eight subsequent time points: immediately before a hypnotic induction, immediately after the induction, after each of five hypnotic suggestions, and at the end of the entire session after awakening. Eighty-six percent of the participants reported decreases in pain intensity and pain unpleasantness from pre-induction to post-induction. Significant omnibus analyses of variance followed by pairwise comparisons indicated statistically significant decreases in pain intensity and unpleasantness from pre-to post induction for both pain intensity and pain unpleasantness, and an additional decrease in pain intensity following the analgesia suggestion. In addition, although not specifically suggested, the decrease in pain that subjects experienced during the hypnotic session persisted after they were instructed to awaken. The ability of the subjects to decrease pain intensity to levels lower than the least pain they had experienced during the past six months was associated with hypnotic responsiveness, while the decrease in pain intensity from pre-induction to post-analgesia suggestion was associated with 6-month average pain. These preliminary findings indicate that hypnotic interventions have the potential to benefit many individuals with SCI-related pain, and that controlled trials of hypnotic analgesia with this population are warranted.
