Frequency bands are labels, not effect claims
Lab conventionWhen the report shows which frequency band a setting falls into, the band name is just a way to describe the frequency. It isn't a claim about a specific effect in the body.
Where it appears in the report: Operating Frequency
The evidence
The names, Delta, Theta, Alpha, Beta, and Gamma, and their ranges come from standard EEG nomenclature and describe the pulse repetition rate only. Popular charts that pair each band with a bodily effect aren't supported by primary research, so we don't make those pairings. Frequency does matter, though. Controlled studies link certain low frequencies to specific responses, for example the roughly 15 Hz signals in established bone-healing devices, and a 2025 randomized study of neck-applied PEMF saw the largest autonomic response at 16 Hz among the 6, 16, and 32 Hz settings it tested. Even so, the response depends on field strength, waveform, and exposure time together, not on frequency alone.
