The present study was part of a larger mixed-methods study concerning facilitators and barriers to living with chronic pain after spinal cord injury. The agreement with themes obtained in qualitative interviews were quantified in a large online survey and overarching themes were defined by factor analysis. The present study aimed to define subgroups based on cluster analysis of the overarching themes' factor scores and to compare the subgroups on pain-related variables. ⋯ PERSPECTIVE: People who experience significant pain impact after spinal cord injury use multiple approaches to manage their pain. Many have concerns about side effects and addiction, and consider information about pain and its management, including pharmacologic, nonpharmacologic, and self-remedies, a high priority. Therefore, patients' personal preferences may provide additional tailoring options for patient-centered treatments.

Polytrauma commonly involves concussion (mild traumatic brain injury [mTBI]) and peripheral trauma including limb fractures. Interactions between mTBI and peripheral injuries are poorly understood, both leading to chronic pain and neurobehavioral impairments. To elucidate these interactions, a murine polytrauma model was developed. mTBI alone resulted in similar increased mechanical allodynia in male and female mice. ⋯ A better understanding of nervous system dysfunction after TBI and polytrauma might help prevent or reduce persistent pain and disability in these patients. PERSPECTIVE: The polytrauma model presented has relevant features of chronic pain and neurobehavioral impairments useful for studying mechanisms involved in their development. This model may have special value in understanding altered descending pain modulation after TBI and polytrauma.

The rapid growth of mobile health (mHealth) devices holds substantial potential for improving care and care outcomes in all patient populations, including older adults with pain. However, existing research reflects a substantial gap in knowledge about how to design, evaluate, and disseminate devices to optimally address the many challenges associated with managing pain in older persons. Given these knowledge gaps, we sought to develop a set of practice-based research priorities to facilitate innovation in this field. ⋯ Participants generated 13 recommendations classified into 2 categories: 1) implications for designing research on mHealth among older adults (eg, conduct research on ways to enhance accessibility of mHealth tools among diverse groups of older adults with pain, expand research on mHealth sensing applications), and 2) implementation of mHealth technology into practice and associated regulatory issues (eg, promote research on ways to initiate/sustain patient behavior change, expand research on mHealth cybersecurity and privacy issues). PERSPECTIVE: This report highlights a set of research priorities in the area of mHealth and later-life pain derived from the joint perspectives of researchers and key stakeholder groups. Addressing these priorities could help to improve the quality of care delivered to older adults with pain.

Patients with chronic overlapping pain conditions have decreased levels of catechol-O-methyltransferase (COMT), an enzyme that metabolizes catecholamines. Consistent with clinical syndromes, we previously demonstrated that COMT inhibition in rodents produces persistent pain and heightened immune responses. Here, we sought to determine the efficacy of manual acupuncture in resolving persistent pain and neuroinflammation in the classic inbred C57BL/6 strain and the rapid-wound healing MRL/MpJ strain. ⋯ Here, we demonstrate that acupuncture alleviates persistent pain and neuroinflammation linked to heightened catecholaminergic tone. Mice with superior healing capacity exhibit greater analgesic efficacy. Findings indicate acupuncture as an effective treatment for chronic overlapping pain conditions and provide insight into treatment response variability.

The self-reported Pain Sensitivity Questionnaire (PSQ) is a valid supplement to experimental pain testing. However, the latent constructs determining the originally proposed 1 general score (PSQ-total) and 2 subscores (PSQ-moderate and PSQ-minor) have not been consistently investigated in population-based studies or between genders. Based on a single construct hypothesized by expert knowledge or alternative constructs upon empirical evidence, PSQ structures were explored and confirmed among 4,820 participants aged 18 to 93 years of the Cooperative Health Research In South Tyrol (CHRIS) study. ⋯ PERSPECTIVE: One dominant latent construct of general pain sensitivity consistently determines responses to the self-reported PSQ. The PSQ-short score maintains similar psychometric properties to the PSQ-total and between genders. This measure is attractive for large-scale research and clinical screening of pain sensitivity.
