Significant difference between the favorite music and white noise conditions (P < .05).
Significant difference between the favorite music and Unwind conditions (P < .05). Higher scores for threshold and tolerance reflect lower pain sensitivity. Lower scores on offset analgesia reflect lower pain scores given at the designated temperatures. Higher scores of CPM reflect greater modulation of pain (less sensitive), and higher scores on pinprick temporal summation reflect greater pain amplification.
