To evaluate the safety and efficacy of l-serine in humans with hereditary sensory autonomic neuropathy type I (HSAN1).
Learn More >OnabotulinumtoxinA is effective in treating chronic migraine (CM), but there are limited data assessing how allodynia affects preventive treatment responses. This subanalysis of the 108-week, multicenter, open-label COMPEL Study assessed the efficacy and safety of onabotulinumtoxinA in people with CM with and without allodynia.
Learn More >To evaluate the association between the cerebrovascular reactivity to carbon dioxide (CO-CVR) and the deep white matter hyperintensity (WMH) burden in patients with migraine.
Learn More >Pain memories are hypothesized to be critically involved in the transition of pain from an acute to a chronic state. To help elucidate the underlying neurobiological mechanisms of pain memory, we developed novel paradigms to study context-dependent pain hypersensitivity in mouse and human subjects, respectively. We find that both mice and people become hypersensitive to acute, thermal nociception when tested in an environment previously associated with an aversive tonic pain experience. This sensitization persisted for at least 24 hr and was only present in males of both species. In mice, context-dependent pain hypersensitivity was abolished by castrating male mice, pharmacological blockade of the hypothalamic-pituitary-adrenal axis, or intracerebral or intrathecal injections of zeta inhibitory peptide (ZIP) known to block atypical protein kinase C (including the protein kinase Mζ isoform). In humans, men, but not women, self-reported higher levels of stress when tested in a room previously associated with tonic pain. These models provide a new, completely translatable means for studying the relationship between memory, pain, and stress.
Learn More >In other disease states, adherence to behavioral therapies has gained attention, with a greater amount of studies discussing, defining, and optimizing adherence. For example, a meta-analysis formally discussed adherence in 25 studies of CBT for 11 different disorders, with only 6 of the 25 omitting addressing or defining adherence. Many studies have discussed the use of text messages, graph-based adherence rates, and email/telephone reminders to improve adherence. This paper examined the available literature regarding adherence to behavioral therapy for migraine as well as adherence to similar therapies in other disease states. The goal of this research is to apply lessons learned from adherence to behavioral therapy for other diseases in better understanding how we can improve adherence to behavioral therapy for migraine.
Learn More >Interventions for low back pain (LBP) commonly target 'dysfunctional' or atypical lumbo-pelvic kinematics in the belief that correcting aberrant movement improves patients' pain and activity outcomes. If atypical kinematic parameters and postures have a relationship to LBP, they could be expected to more prevalent in people with LBP compared to people without LBP (NoLBP). This exploratory study measured, defined and compared atypical kinematic parameters in people with and without LBP.
Learn More >The role of avoidance and endurance behaviour is well established in chronic musculoskeletal pain, but less is known about its significance in migraine.
Learn More >Research in migraine points towards central-peripheral complexity with a widespread pattern of structures involved. Migraine-associated neck and shoulder muscle pain has clinically been conceptualized as myofascial trigger points (mTrPs). However, concepts remain controversial, and the identification of mTrPs is mostly restricted to manual palpation in clinical routine. This study investigates a more objective, quantitative assessment of mTrPs by means of magnetic resonance imaging (MRI) with T2 mapping.
