PVB remains an underused block. It is easy to perform reliable and effective blocks for a wide variety of applications both for acute or chronic pain. As evidence continues to be published showing the advantages of PVB versus traditional methods of pain control, it is hoped that PVB will become part of the standard repertoire of blocks used in teaching hospitals and in private practice.

Although emotion regulation capacities have been linked to adjustment among people with chronic pain, researchers have yet to determine whether these capacities are related to functioning independent of established facets of pain coping. The present study was designed to address this gap. ⋯ Conversely, features of emotion regulation did not improve the prediction model for pain-related disability. Findings suggest emotion regulation capacities may have a unique role in the prediction of specific facets of adjustment among people with chronic pain.

Effect of muscle load tasks with maximal isometric contractions on oxygenation of the trapezius muscle and sympathetic nervous activity in females with chronic neck and shoulder pain.
Sympathetic nervous activity contributes to the maintenance of muscle oxygenation. However, patients with chronic pain may suffer from autonomic dysfunction. Furthermore, insufficient muscle oxygenation is observed among workers with chronic neck and shoulder pain. The aim of our study was to investigate how muscle load tasks affect sympathetic nervous activity and changes in oxygenation of the trapezius muscles in subjects with chronic neck and shoulder pain. ⋯ Subjects with neck and shoulder pain showed lower oxygenation and blood flow of the trapezius muscles responding to isometric exercise, compared with asymptomatic subjects. Subjects with neck and shoulder pain also showed no significant changes in the LF/HF ratio of HRV responding to isometric exercise, which would imply a reduction in sympathetic nervous activity.
