Review Meta Analysis
Prevalence and interference of chronic pain among people with haemophilia: A systematic review and meta-analysis.
Chronic pain is a common condition among people with hemophilia (PWH), associated with joint deterioration due to repeated joint bleeds. This systematic review and meta-analysis aimed to determine the prevalence of chronic pain due to haemophilia and to analyze its interference in the lives of patients. A systematic search was performed in May and June 2019 and updated in February 2021, using PubMed, EMBASE, Web of Science and SciElo. ⋯ Research in the hemophilia field should clearly distinguish between acute and chronic pain and provide complete characterization of study samples. PERSPECTIVE: Pain is a central issue in the lives of people with hemophilia, posing a significant challenge for healthcare providers. A clear picture of chronic pain due to hemophilia is precluded by high heterogeneity among studies and various definitions used to investigate its prevalence.

Excessive generalization of fear and avoidance are hallmark symptoms of chronic pain disability, yet research focusing on the mechanisms underlying generalization of avoidance specifically, is scarce. Two experiments investigated the boundary conditions of costly pain-related avoidance generalization in healthy participants who learned to avoid pain by performing increasingly effortful (in terms of deviation and force) arm-movements using a robot-arm (acquisition). During generalization, novel, but similar arm-movements, without pain, were tested. ⋯ These results suggest that uncertainty about the occurrence of pain may delay recovery, due to reduced disconfirmation of threat beliefs when exploring, resulting in persistent avoidance. PERSPECTIVE: This article demonstrates generalization of instrumentally acquired costly pain-related avoidance in healthy people under conditions of uncertainty. The results suggest that targeting pain-related uncertainty may be a useful tool for clinicians adopting a psychological approach to treating excessive pain-related avoidance in chronic pain.

Exercise can reduce pain, however the effect of painful versus non-painful exercises is uncertain. The primary aim of this randomized crossover study was to compare the effect of painful versus nonpainful isometric shoulder exercises on pain intensity after exercise in individuals with rotator cuff-related shoulder pain. Secondary exploratory aims were to describe the effects on pressure pain thresholds (PPTs), conditioned pain modulation (CPM) and muscle strength. ⋯ PERSPECTIVE: This study evaluated for the first time in individuals with rotator cuff-related shoulder pain the effects of painful versus non-painful isometric exercises on different pain-related outcome measures. Both painful and non-painful isometric exercises caused a moderate but relatively short-lasting increase in shoulder pain in individuals with rotator cuff-related shoulder pain. Trial registration number: (ClinicalTrials.gov) NCT03675399.

Randomized Controlled Trial Multicenter Study
Yoga, Eurythmy Therapy and Standard Physiotherapy (YES-Trial) for Patients with Chronic Non-specific Low Back Pain: a Three-Armed Randomized Controlled Trial.
We aimed to evaluate the effects of yoga and eurythmy therapy compared to conventional physiotherapy exercises in patients with chronic low back pain. In a three-armed, multicentre, randomized controlled trial, patients with chronic low back pain were treated for 8 weeks in group sessions (75 minutes once per week). Primary outcome was patients' physical disability (measured by RMDQ) from baseline to week 8. ⋯ Clinical Trials Register: DRKS-ID: DRKS00004651 Perspective: This article presents the results of a multicentre three-armed randomized controlled trial on the clinical effects of three 8-week programs in patients with chronic low back pain. Compared to the 'gold standard' of conventional physiotherapeutic exercises, eurythmy therapy and yoga therapy lead to comparable symptomatic improvements in patients with chronic low back pain. However, the within-group effect sizes were small to moderate and did not reach clinical meaningfulness on patients' physical disability (RMDQ).

The failure of past practices and policies related to opioid prescribing for chronic pain has led federal agencies and professional organizations to recommend multimodal approaches that prioritize evidence-based nonpharmacological pain treatments (NPTs). These multimodal approaches, which include both traditional and complementary/integrative approaches, hold great promise for reducing the burden of chronic pain and reducing opioid use. ⋯ Despite these dual crises of chronic pain and opioid use in the U. S., there has never been a concerted effort to broadly educate the American public about these issues and NPT pain management options.
