The aim of the study was to investigate the effect of acute trapezius pain, induced by delayed onset of muscle soreness (DOMS), on habitual trapezius activity. Long-term (5 h) surface electromyographic (sEMG) activity was recorded bilaterally from the clavicular, descending, transverse, and ascending trapezius on two consecutive weekdays in eleven female subjects (mean age 22 years, range 20-24 years). Body and arm posture were recorded by inclinometers. ⋯ In contrast, trapezius sEMG activity remained unchanged for all other trapezius parts and postures. This study indicates that acute trapezius pain induces elevated habitual trapezius activity during periods with low biomechanical loading of the shoulder/neck muscles with the elevated sEMG activity being restricted to the painful part of the muscle. In contrast to the pain-adaption model, the current study indicates a relation between acute muscle pain and elevated low-level muscle activity; however, it remains unknown if development of chronic muscle pain can be preceded by an initial stage with elevated muscle activity.

Minimal access surgery (MAS) in adults is associated with less postoperative pain in comparison to conventional 'open' surgery. It is not known whether this holds true for neonates as well. Less pain would imply that opioid consumption can be reduced, which has a beneficial effect on morbidity. ⋯ Minimal access surgery for the repair of esophageal atresia or congenital diaphragmatic hernia is not associated with less cumulative opioid doses.

Review
The influence of informal social support on risk and prognosis in spinal pain: a systematic review.
Spinal pain is very common and has considerable consequences for the individual (e.g. loss of employment, disability) as well as increased health care costs. It is now widely accepted that biological, psychological and social factors impact on spinal pain outcomes. The majority of research on social factors has been employment related, with little attention to the influence of informal social support (e.g. families, friends, social groups). ⋯ Evidence of social support as a factor for risk of occurrence was inconclusive with three studies reporting no significant associations with the remaining two studies reporting weak associations. Evidence of an effect of social support and prognosis revealed inconsistent findings. The variation in findings may reflect ongoing difficulties surrounding the conceptualisation and measurement of informal social support.

Comparative Study
Parental catastrophizing about their child's chronic pain: are mothers and fathers different?
Preliminary evidence suggests that parental catastrophizing about their child's pain may be important in understanding both parental responses to their child's pain and the child's pain experience. However, little is known about potential differences between mothers and fathers. There were three aims of the present study addressing this lack of knowledge: (i) to investigate the three-factor structure of the German version of the Parental Pain Catastrophizing Scale (PCS-P) (Goubert et al., 2006) in mothers and fathers of children with chronic pain, (ii) to explore differences between mothers and fathers in parental catastrophizing, (iii) to investigate the contribution of parental catastrophizing on the child's chronic pain problem and pain-related parent behavior. ⋯ Both maternal and paternal catastrophizing contributed significantly to heightened parental solicitous responses. Fathers' but not mothers' catastrophizing also contributed to heightened distracting responses. The present findings attest to the importance of maternal and paternal catastrophizing for the child's pain characteristics and pain-related parent behavior, which are both relevant for treatment conceptualization.
