Compiled by Canadian Chiropractor Dr. Michael Ho: The principles and clinical applications of 4 major electrotherapy technologies
Since the popularization of home electrotherapy devices, many people have heard of terms like TENS, EMS, and NMES. But what are their actual differences? This Wiki, compiled by Dr. Michael Ho's team, deeply analyzes the principles, applications, and safety of 4 major electrotherapy technologies.
🔬 4 Major Electrotherapy Technologies
① TENS Most Widespread
Transcutaneous Electrical Nerve Stimulation — The most popular home electrotherapy technology, it uses low-frequency current to stimulate subcutaneous sensory nerves, blocking pain transmission to achieve immediate pain relief.

② EMS Sports Recovery
Electrical Muscle Stimulation — Directly stimulates muscle contraction, primarily used for sports recovery, muscle strengthening, and post-surgery rehabilitation. It also helps improve circulation and reduce swelling.

③ NMES Nerve Rehabilitation
Neuromuscular Electrical Stimulation — The most common rehabilitation technology in physical therapy clinics, used for post-stroke muscle re-activation, nerve injury recovery, and diabetic peripheral neuropathy.

④ AMP ⭐ DR-HO'S Patented
Auriculotherapy Massage Pulse (AMP) — A patented technology developed by Dr. Michael Ho over 35 years of pain clinical research, it intelligently switches between TENS / EMS / NMES modes, preventing nerve adaptation, with a pain relief effect 1.8 times that of a single TENS.
