The aim of this study was to establish the somatosensory profiles of patients with cervical radiculopathy and patients with nonspecific neck-arm pain associated with heightened nerve mechanosensitivity (NSNAP). Sensory profiles were compared to healthy control (HC) subjects and a positive control group comprising patients with fibromyalgia (FM). Quantitative sensory testing (QST) of thermal and mechanical detection and pain thresholds, pain sensitivity and responsiveness to repetitive noxious mechanical stimulation was performed in the maximal pain area, the corresponding dermatome and foot of 23 patients with painful C6 or C7 cervical radiculopathy, 8 patients with NSNAP in a C6/7 dermatomal pain distribution, 31 HC and 22 patients with FM. ⋯ Both neck-arm pain groups demonstrated increased cold sensitivity in their maximal pain area (P<.03) and the foot (P<.009), and this was also the dominant sensory characteristic in patients with NSNAP. Both neck-arm pain groups differed from patients with FM, the latter characterised by a widespread gain of function in most nociceptive parameters (thermal, pressure, mechanical pain sensitivity P<.027). Despite commonalities in pain characteristics between the 2 neck-arm pain groups, distinct sensory profiles were demonstrated for each group.

The communication of pain has received a great deal of attention in the pain literature; however, one form of pain communication--emotional disclosure of pain-related distress (e.g., sadness, worry, anger about pain)--has not been studied extensively. This study examined the extent to which this form of pain communication occurred during an observed conversation with one's spouse and also investigated the correlates and consequences of disclosure. Individuals with chronic pain (ICP) and their spouses (N=95 couples) completed several questionnaires regarding pain, psychological distress, and relationship distress as well as video recorded interactions about the impact of pain on their lives. ⋯ Furthermore, spouses were more likely to engage in invalidation after attempting more neutral or validating responses, suggesting an erosion of support when ICPs engaged in high rates of disclosure. Correlates of spousal invalidation included both spouses' helplessness catastrophizing, ICPs' affective distress about pain, and spouses' anxiety, suggesting that both partners' distress are implicated in maladaptive disclosure-response patterns. Findings are discussed in light of pain communication and empathy models of pain.
