B+Martiny K, Lunde M, Bech P. Transcranial low voltage pulsed electromagnetic fields in patients with treatment-resistant depression. Biological Psychiatry. 2010;68(2):163-169.
Key Findings: Active T-PEMF produced statistically and clinically better outcomes than sham; effect size ~0.62 on Hamilton scale.
Population: Patients with treatment-resistant major depression
Anxiety
Moderate to strong evidence across multiple anxiety conditions
PEMF Vagus Nerve Stimulation for Anxiety
B+Evaluating PEMF vagus nerve stimulation through neck application: A randomized placebo study with volunteers. Taylor & Francis. 2025.
Key Findings: Double-blind placebo-controlled trial with 485 volunteers. Significant anxiety reduction with 16 Hz frequency showing most substantial improvements. PEMF modulates autonomic activity.
Population: 485 volunteers

B+Efficiency of pulsed electromagnetic fields on pain, disability, anxiety, depression, and quality of life in patients with cervical disc herniation. PMC. 2019.
Key Findings: RCT comparing PEMF + TENS + hot pack vs sham. Both groups showed significant anxiety improvement, with PEMF group showing more substantial improvements at 12-week follow-up.
Population: Patients with cervical disc herniation
HRV Biofeedback
Strong evidence for stress, anxiety, and autonomic regulation
Single-Session HRV Biofeedback for Performance Anxiety
B+Wells R, Outhred T, Heathers JAJ, Quintana DS, Kemp AH. Matter over mind: a randomized-controlled trial of single-session biofeedback training on performance anxiety. PLoS ONE. 2012;7(10):e46597.
