“…Pain expectancies have been associated with a number of indices of pain sensitivity in the context of experimental pain‐testing paradigms, both among individuals with chronic pain conditions and healthy controls (France et al, ; Goffaux et al, ; Hanssen et al, ; Van Damme, Crombez, & Eccleston, ), although the present findings are the first linking higher expectancies for pain with increased TS of pain. The literature also points to consistent associations between pain expectancies and numerous adverse pain‐related outcomes, including self‐reported pain intensity and disability (Boersma & Linton, ; Gandhi, Davey, & Mahomed, ; Mun et al, ; Sullivan, Rodgers, et al, ), emotional distress (Carriere, Thibault, Milioto, et al, ; Sullivan, Rodgers, et al, ) and prolonged work disability (Carriere, Thibault, & Sullivan, ; Carriere, Thibault, & Sullivan, ; Cole, Mondloch, & Hogg‐Johnson, ; duBois & Donceel, ; Gross & Battié, ). This study extends previous findings by showing that pain expectancies are associated with elevated TS of pain, a marker of central pain‐facilitatory processes, selectively in CLBP patients.…”

Background Pain expectancies are associated with altered pain sensitivity in individuals with chronic pain. However, little is known about the processes by which pain expectancies impact pain processing. This study assessed the association between pain expectancies and temporal summation (TS) of pain, and examined whether pain catastrophizing mediated this association. Methods In this cross‐sectional study, participants (437 chronic low back pain [CLBP] patients, 115 controls) completed self‐report measures of pain intensity, pain expectancies and pain catastrophizing before undergoing psychophysical pain‐testing procedures designed to assess mechanical TS of mechanical pain. Pearson's correlations examined the associations between study variables in CLBP patients and controls. Bootstrapping mediation analyses assessed the mediating role of pain catastrophizing on the association between pain expectancies and TS of pain. Results Temporal summation of pain was significantly associated with pain expectancies (r = 0.113) and pain catastrophizing (r = 0.171) in CLBP patients. Results of mediation analyses revealed that pain catastrophizing mediated the relationship between pain expectancies and TS of pain in CLBP patients (ab = 0.309, 95% CI = 0.1222–0.5604), but not in healthy controls (ab = −0.125, 95% CI = −0.5864 to 0.0244). Conclusions The findings from this study suggest that compared to controls, CLBP patients show increased sensitivity to mechanical pain procedures and enhanced pain‐facilitatory processing, proving further evidence for changes in central nervous system pain processing in CLBP patients. Our results also suggest that pain catastrophizing may be the mechanism by which pain expectancies are associated with TS of pain in CLBP patients. Significance Individuals with chronic low back pain who expect higher levels of pain and catastrophize about their pain are more likely to experience altered pain sensitivity. Our results point to catastrophizing as a mechanism of action through which psychological factors may operate and lead to the development and maintenance of chronic low back pain.

“…Perceived neck load at work was also measured with one question: "Do you consider the load on your neck at work is: light, moderate or heavy". The Borg scale (6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20) was used to indicate the intensity of physical demands at work. A binary scale (hardly ever/frequently) was used to measure the frequency of having arms above shoulder height for more than 30 min.…”

“…[8,9] The IEQ scores are high in patients who believe that the liability for their injury rests in another person, [10] experience pain for a long duration, [10] get injured in a motor vehicle accident, [9] have severe pain, [9] and psychological disturbance. [9] In patients with sub-acute or chronic WAD, the IEQ scores associate with pain severity, [11] displays of pain behavior, [12] work disability, [11,13] depressive symptoms, [14] and post-traumatic stress symptoms.

Introduction This study aimed to investigate the differences in the Injustice Experience Questionnaire (IEQ) scores during the early period after the diagnosis of Whiplash-associated disorder (WAD) between Japanese and Canadian samples, and the associations between the IEQ scores and treatment terms in Japanese patients with acute WAD. Methods We used secondary data for the IEQ scores of Canadian patients with acute WAD. In Japan, we collected data from 85 consecutively enrolled patients with acute WAD, and their treatment terms were collected; these referred to the number of days between the date of injury and the closure date of the insurance claim and the number of treatment visits. Before treatment, the Numeric Rating Scale, Neck Disability Index, Hospital Anxiety and Depression Scale, IEQ, and Euro Quality of Life five-dimensional questionnaire were administered. The variables were subjected to multivariate analysis with each treatment term. Results The IEQ scores were higher in Japan than in Canada. Through multiple regression analysis, IEQ scores were independently correlated with treatment terms. The optimal cutoff point of the IEQ scores for a prolonged treatment term was 21 and 22 points, respectively. Conclusions The IEQ scores were associated with treatment terms in patients with acute WAD in Japan.
