Pain

Interrupting ongoing activities whilst intending to resume them later is a natural response to pain. Whereas this response facilitates pain management, at the same time it may also disrupt task performance. Previous research has shown that activity interruptions by pain impair subsequent resumption of the activity, but not more than pain-irrelevant interruptions. ⋯ Pain catastrophizing did not influence the results. As in previous studies, activity interruptions by pain were shown to impair the resumption of a task that requires keeping to a step sequence, but not more than interruptions by nonpainful stimuli. Potential explanations are discussed.

Review Meta Analysis
Surgical interventions for the treatment of painful neuroma: a comparative meta-analysis.
A consensus on the optimal treatment of painful neuromas does not exist. Our objective was to identify available data and to examine the role of surgical technique on outcomes following surgical management of painful neuromas. In accordance with the PRISMA guidelines, we performed a comprehensive literature search to identify studies measuring the efficacy of the surgical treatment of painful neuromas in the extremities (excluding Morton's neuroma and compression neuropathies). ⋯ No significant differences were seen between surgical techniques. Among studies with a mean pain duration greater than 24 months, or median number of operations greater than 2 prior to definitive neuroma pain surgery, excision and transposition or neurolysis and coverage were significantly more likely than other operative techniques to result in a meaningful reduction in pain (P < 0.05). Standardization in the reporting of surgical techniques, outcomes, and confounding factors is needed in future studies to enable providers to make comparisons across disparate techniques in the surgical treatment of neuroma pain.

Multicenter Study
Variability in negative emotions among individuals with chronic low back pain: relationships with pain and function.
Chronic pain is associated with elevated negative emotions, and resources needed to adaptively regulate these emotions can be depleted during prolonged pain. Studies of links between pain, function, and negative emotions in people with chronic pain, however, have focused almost exclusively on relationships among mean levels of these factors. Indexes that may reflect aspects of emotion regulation have typically not been analyzed. ⋯ Spouse-observed pain and pain behaviors were also associated with greater variability in patients' negative emotions. Test of the inverse associations between negative emotion level and variability in pain and function were significant but weaker in magnitude. These findings support the notion that chronic pain may erode negative emotion regulation resources, to the potential detriment of intra- and inter-personal function.
