This study investigated the relative contribution of individual, workplace, psychosocial and physiological features associated with neck pain in female office workers towards developing appropriate intervention programs. Workers without disability (Neck Disability Index (NDI) score < or = 8, n=33); workers with neck pain and disability (NDI > or = 9/100, n=52) and 22 controls (women who did not work and without neck pain) participated in this study. Two logistic regression models were constructed to test the association between various measures in (1) workers with and without disability, and (2) workers without disability and controls. ⋯ Workers without disability and controls could only be differentiated by greater muscle activity in the cervical flexors and extensors during a typing task. No psychosocial domains remained in either regression model. These results suggest that impairments in the sensory and motor system should be considered in any assessment of the office worker with neck pain and may have stronger influences on the presenting symptoms than workplace and psychosocial features.

Clinical Trial
Homotopic stimulation can reduce the area of allodynia in patients with neuropathic pain.
Allodynia is a common, troublesome feature of neuropathic pain conditions. In a previous study of postherpetic neuralgia we observed that repeated tactile stimulation appeared to reduce the size of the area of allodynia in some patients. We have undertaken a pragmatic clinical study to characterise this phenomenon in neuropathic pain patients with a range of different aetiologies. ⋯ There was no change in heat pain threshold at a distant site following allodynic stimulation, suggesting no activation of diffuse noxious inhibitory control. Repeated thermal noxious stimulation (median NRS 7) could also elicit changes (>30%) in the area of allodynia in some patients (reductions in 7/20, increases in 3/20). Thus, we have found that a brief period of homotopic painful stimulation can reduce the area of allodynia in around half of patients with established neuropathic pains.

To enhance the awareness that biased pain estimation may undermine its treatment, we sought to determine the congruence categories (CCs) between inpatient self-reported pain (PSRP) and nurse pain-evaluation (NEP) and to look for associations between CCs and inpatient and situational moderators. ⋯ PSRP-NEP congruence was limited while CCs were associated with PSRP, inpatient and situational moderators. Further prospective studies are needed to verify generalization and whether the studied moderators operate through patient stereotyping mechanisms. Awareness of the influence of such mechanisms on pain evaluation may ameliorate pain assessment.

The aim of this study was to investigate the relationships between goal frustration, coping and well-being in the context of adolescent headache. Firstly, we investigated whether adolescents with weekly, monthly or no headache complaints differed with regard to the importance assigned to their personal goals, experience of goal frustration, coping with goal frustration and well-being. Secondly, the extent to which goal and coping factors contributed to well-being and whether this relationship differed according to the frequency of headache complaints was examined. ⋯ After controlling for individual and headache characteristics, frustration of self acceptance and health goals, and the use of self blame, rumination and other blame were consistently related to lower well-being. Moreover, interactions with headache group indicated that for adolescents with weekly headache, greater frustration of school and self acceptance goals and a lower importance assigned to health goals was more detrimental to well-being than for those with no headache complaints. We conclude that frustration to goal pursuit and strategies for coping with this frustration are important factors in adolescent well-being and may offer important targets for intervention.

This study investigated attentional biases for linguistic pain-related stimuli in individuals suffering from chronic headaches and healthy controls. Attentional bias was assessed using a visual probe (also reported as dot probe in previous investigations) task which presented pain-related (sensory and affective) and neutral words at two exposure duration conditions, 500 and 1250 ms. ⋯ No significant differences between groups were found in attentional bias scores at the shorter stimulus duration of 500 ms, which instead correlated significantly with trait anxiety. Results are discussed in relation to research into pain-related and anxiety-related biases in initial orienting and maintained attention.
