Pain neuroscience education (PNE) is an approach used in the management of chronic musculoskeletal pain. Previous reviews on PNE and other pain interventions, have focused on mean treatment effects, but in the context of "precision medicine," any inter-individual differences in treatment response are also important to quantify. If inter-individual differences are present, and predictors identified, PNE could be tailored to certain people for optimizing effectiveness. ⋯ PERSPECTIVE: We bring a novel method to pain science for calculating inter-individual differences in response to a treatment. This is conductedwithin the context of a systematic review and meta-analysis on PNE. We highlight how using erroneous methods for calculating inter-individual differences can drastically change conclusions when compared to appropriate methods.

Review Meta Analysis
Exercise-induced hypoalgesia in healthy individuals and people with chronic musculoskeletal pain: a systematic review and meta-analysis.
Exercise-induced hypoalgesia (EIH) is a reduction in pain that occurs during or following exercise. Randomized controlled studies published from 1980 to January 2020 that examined experimentally induced pain before and during/following a single bout of exercise in healthy individuals or people with chronic musculoskeletal pain were systematically reviewed. Data were analyzed using random-effects meta-analyses and studies were appraised using the Cochrane Risk of Bias tool and GRADE. ⋯ Registration: PROSPERO ID: CRD42018085886. PERSPECTIVE: Based on low-quality data from small samples, a single bout of aerobic exercise reduces experimental pain in healthy individuals. The evidence is unclear in people with chronic musculoskeletal pain but warrants further investigation due to the limited number of studies in these populations.

Review Meta Analysis
Is transcranial direct current stimulation (tDCS) effective for the treatment of pain in fibromyalgia? A systematic review and meta-analysis.
Fibromyalgia is a debilitating condition characterized by chronic widespread pain. It is believed to be caused by dysfunction of the central nervous system (CNS) but current treatments are largely ineffective. Transcranial direct current stimulation (tDCS), a neuromodulation technique that targets the CNS, may offer a new line of treatment. ⋯ This systematic review and meta-analysis synthesizes current evidence for the clinical effectiveness of tDCS in the treatment of fibromyalgia pain. There is only tentative evidence of pain reduction when active tDCS is compared to sham. High heterogeneity and risk of bias across studies suggest a need for further empirical research.

Review Meta Analysis Comparative Study
Comparing central pain processing in individuals with non-traumatic neck pain and healthy individuals: a systematic review and meta-analysis.
This systematic review and meta-analysis examined the evidence for altered central pain processing in people with nontraumatic neck pain and the relationship among central pain processing, demographics, and pain-related characteristics. Case-control studies reporting measures of altered central pain processing using quantitative sensory testing were reviewed. Standardized mean differences (SMDs) and 95% confidence intervals between people with nontraumatic neck pain and controls were calculated. ⋯ This review suggests that altered central pain processing is present in people with nontraumatic neck pain and may be associated with disability levels and age. PERSPECTIVE: This review found moderate-quality evidence of mechanical hyperalgesia at remote nonpainful sites in patients with nontraumatic neck pain compared with controls, indicating altered central pain processing. However, more studies are needed to confirm findings from dynamic quantitative sensory testing.

Review Meta Analysis
Cupping for patients with chronic pain: a systematic review and meta-analysis.
There is a growing interest in nonpharmacological pain treatment options such as cupping. This meta-analysis aimed to assess the effectiveness and safety of cupping in chronic pain. PubMed, Cochrane Library, and Scopus were searched through November 2018 for randomized controlled trials on effects of cupping on pain intensity and disability in patients with chronic pain. ⋯ Perspective: This article presents the results of a meta-analysis aimed to assess the effectiveness and safety of cupping with chronic pain. The results suggest that cupping might be a treatment option; however, the evidence is still limited due to methodical limitations of the included trials. High-quality trials seem warranted.
