: Devices typically allow for adjustments in frequency (pulses per second) and intensity (strength). Lower frequencies (2–10 Hz) are often used for chronic conditions, while higher frequencies may be used for acute pain.

Electro-acupuncture (EA) is a specialized form of acupuncture that applies a mild pulsating electric current to needles inserted at specific body points . It aims to enhance the healing effects of traditional manual manipulation by providing continuous, consistent, and controllable stimulation. Core Mechanism and Procedure

: EA is favored in clinical research because the stimulation parameters can be precisely measured and standardized. Clinical Applications

: It can provide much stronger stimulation than manual twirling, which is often necessary for difficult neurological cases like paralysis or severe neuralgia.
