Patients with complex regional pain syndrome type I (CRPSD1) may have thermal allodynia after application of a non-noxious thermal stimulus to the affected limb. We measured the warm, cold, heat-evoked pain threshold and the cold-evoked pain threshold in the affected area of 16 control patients and patients with complex regional pain syndrome type 1/RSD to test the hypothesis that allodynia results from an abnormality in sensory physiology. ⋯ This study suggests that thermal allodynia in patients with CRPS1/RSD results from decreased cold-evoked and heat-evoked pain thresholds. The thermal pain thresholds are reset (decreased) so that non-noxious thermal stimuli are perceived to be pain (allodynia).

To determine the sleep quality and quality of life for individuals with degenerative spinal disease or failed back surgery syndrome. ⋯ These data suggest that physical functioning, duration of pain, and age may be more important than pain intensity and depressed mood in contributing to decreased overall sleep quality and sleep latency. The contribution of physical functioning was particularly strong and should be included in subsequent studies of sleep, pain, and mood. The SF-36 should be compared to pain-specific quality-of-life measures to further evaluate the usefulness of this instrument with outpatients with chronic nonmalignant pain conditions.

To determine the part played by drag on the pectoral girdle muscles of women in the production of pain in these muscles from breast weight being carried at the shoulders through the brassiere straps. ⋯ Presence or absence of muscle pain after the trial period. Long-term outcome was presence or absence of muscle pain and tenderness. Seventy-nine percent of patients decided to remove breast weight from the shoulder permanently because it rendered them symptom free.

The objective of this study was to evaluate Mikail et al.'s hypothesis that adult attachment styles are associated with important pain-related variables such as pain and disability levels. ⋯ The attachment theory holds promise for understanding reactions to pain conditions, and Mikail et al.'s model warrants further investigation.
