Experience of Polish Physicians on Electromagnetic Hypersensitivity

Research RF Safe Research Library Jan 1, 2025

This cross-sectional questionnaire study surveyed 355 Polish physicians about EMF health effects and electromagnetic hypersensitivity (EHS). Physicians reported limited knowledge and low familiarity with WHO guidance for managing people who believe they are hypersensitive to EMF, though most were willing to learn…

Prospective long-term follow-up of patients with idiopathic environmental intolerance attributed to electromagnetic fields after a provocation trial

Research RF Safe Research Library Jan 1, 2025

This long-term follow-up recruited participants from an earlier IEI-EMF provocation trial and re-administered the same questionnaire by telephone. Of 70 completers (35 IEI-EMF patients and 35 referents), 62.9% of patients reported recovery after an average of 1.8 years, with most recoveries described as spontaneous.…

Pilot questionnaire survey shows the lack of diagnostic criteria for electromagnetic hypersensitivity: a viewpoint

Research RF Safe Research Library Jan 1, 2025

This viewpoint reports results from a pilot questionnaire survey of 142 self-declared EHS/IEI-EMF individuals and argues that current evidence and tools do not allow a definitive medical diagnosis of sensitivity to low-level wireless radiation. It notes that many reported diagnoses appear anecdotal and that tests…

Greater prevalence of symptoms associated with higher exposures to mobile phone base stations in a hilly, densely populated city in Mizoram, India

Research RF Safe Research Library Jan 1, 2025

This cross-sectional study compared 183 higher-exposed residents with 126 matched reference residents and assessed symptoms via questionnaire alongside in-home RF-EMF power density measurements from mobile phone base stations. Higher exposure (including proximity within 50 m and power densities of 5–8 mW/m2) was…

Skin Fibroblasts from Individuals Self-Diagnosed as Electrosensitive Reveal Two Distinct Subsets with Delayed Nucleoshuttling of the ATM Protein in Common

Research RF Safe Research Library Jan 1, 2025

This study reports on 26 adults self-diagnosed with electromagnetic hypersensitivity (EHS) who provided skin biopsies to generate primary fibroblast lines. The authors describe two EHS subsets based on questionnaire and DNA damage-related measures, and report delayed ATM nucleoshuttling after X-ray exposure in all…

Chicken or egg? Attribution hypothesis and nocebo hypothesis to explain somatization associated to perceived RF-EMF exposure

Research RF Safe Research Library Jan 1, 2025

This longitudinal cohort study examined the temporal relationship between somatization and perceived RF-EMF exposure, comparing the attribution hypothesis with the nocebo hypothesis. Using AMIGO questionnaire data from 2011 and 2015, regression analyses suggested the attribution hypothesis more often explained…

Could electrohypersensitivity be a specific form of high sensory processing sensitivity?

Research RF Safe Research Library Jan 1, 2025

This cross-sectional questionnaire study (n=100) examined whether electrohypersensitivity (EHS) overlaps with high sensory processing sensitivity (HSPS). A higher proportion of HSPS was observed among those reporting EHS symptoms, alongside significant differences in anxiety/depression symptomatology and EMF-related…

A Pilot Study Evaluating the Feasibility and Efficacy of an In-Home Resonance-Based Electromagnetic Field Protection Device on Improving Markers of Health and Cognitive Function Among a Sample of Healthy Adults.

Research RF Safe Research Library Jan 1, 2024

This single-arm 12-week pilot/feasibility study enrolled 25 relatively healthy adults to evaluate an in-home resonance-based EMF protection device (BluShield). The abstract reports high compliance and no adverse events, with modest improvements in self-reported health, several cognitive questionnaire domains, and…

Effect of a Smartphone-Based App on the Quality of Life of Patients With Heart Failure: Randomized Controlled Trial.

Research RF Safe Research Library Jan 1, 2020

This randomized controlled trial evaluated whether adding a smartphone-based app to routine care improves quality of life in hospitalized patients with heart failure. Over 3 months, the app group reported significantly better quality-of-life scores than the control group on the Minnesota Living with Heart Failure…

[Effect of stress and intesity of mobile phone using on the health and subjective symptoms in GSM workers].

Research RF Safe Research Library Jan 1, 2017

This cross-sectional questionnaire study examined stress and mobile phone use in GSM network employees. Stress measures differed across groups defined by phone use duration and conversation length. Speaking on a mobile phone for more than 60 minutes/day was associated with a higher reported risk of headaches even…

Efficacy of extremely low-frequency magnetic field in fibromyalgia pain: A pilot study.

Research RF Safe Research Library Jan 1, 2016

This pilot randomized study evaluated systemic extremely low-frequency magnetic field (ELF-MF) therapy versus sham in 37 women with fibromyalgia using a crossover sequence. The abstract reports significant short-term reductions in pain and improvements in fibromyalgia-related symptom and function questionnaires…

Is smartphone a necessity or luxury among orthopedic specialty?

Research RF Safe Research Library Jan 1, 2014

This cross-sectional questionnaire study assessed how orthopaedic residents and consultants in Karachi used smartphones for clinical work and academics. Most respondents owned smartphones and reported using apps and internet/email, but fewer used them to share clinical data. The paper does not assess electromagnetic…

Interference between active implanted medical devices and electromagnetic field emitting devices is rare but real: results of an incidence study in a population of physicians in France.

Research RF Safe Research Library Jan 1, 2014

This cross-sectional incidence survey used a postal questionnaire to assess physician-observed interference incidents between EMF-emitting devices and active implanted medical devices (AIMDs) in France. Among 1,188 participating physicians, 16% reported AIMD failures, typically of moderate severity but sometimes…

Cell phone usage and erectile function.

Research RF Safe Research Library Jan 1, 2013

This pilot case-control study compared 20 men with erectile dysfunction to 10 healthy controls using SHIM/IIEF scores and a questionnaire on cell phone habits. Weekly call time was not significantly different between groups, but men with ED reported significantly longer daily time carrying a switched-on phone. The…

Prenatal and Postnatal Cell Phone Exposures and Headaches in Children.

Research RF Safe Research Library Jan 1, 2012

This cohort analysis from the Danish National Birth Cohort examined whether prenatal and/or postnatal cell phone exposure was associated with headaches in children at age seven.
