The Effect of 5G Mobile Phone Electromagnetic Exposure on Corticospinal and Intracortical Excitability in Healthy Adults: A Randomized Controlled Pilot Study
This randomized controlled pilot study examined whether short-term 5G mobile phone exposure (3.6 GHz; 0.0030 W/m2) affects corticospinal and intracortical excitability in 19 healthy adults. No significant exposure-by-time interactions were found for CSE, ICF, SICI, or LICI when comparing 5-minute, 20-minute, and sham conditions. Bayesian analyses were reported as inconclusive (Bayes factors ≈ 1), and the authors recommend cautious interpretation and further research.
Key points
- The study tested 5G exposure at 3.6 GHz with a reported power density of 0.0030 W/m2.
- Nineteen healthy adults underwent 5-minute, 20-minute, and sham exposure conditions.
- CSE, ICF, SICI, and LICI were measured using single- and paired-pulse transcranial magnetic stimulation before and immediately after exposure.
- No significant exposure-by-time interactions were reported for any neurophysiological outcome (all p > 0.15).
- Bayesian analyses yielded Bayes factors close to 1, described as providing limited support for either an effect or no effect.
- The authors characterize any potential influence as likely subtle with the present methods and call for longer exposures and more sensitive measures.
