The device looks like a thick metallic pen and works on the principle of TENS (Transcutaneous Electrical Nerve Stimulation). When the tip of the pen touches a trigger point or an "acupoint," it delivers a mild electric pulse that stimulates the nerves and muscles. This helps in blocking pain signals to the brain and increasing blood circulation in specific areas like the neck, shoulders, back, or joints
- Needleless Acupuncture: Provides the benefits of meridian therapy and trigger point massage without skin penetration, making it painless and non-invasive [1, 2].
- Adjustable Intensity Levels: Most models feature a digital display with 1 to 9 intensity levels, allowing users to customize the strength of the pulse based on their comfort [2, 3].
- Interchangeable Massage Heads: Usually comes with 3 to 5 specialized tips:
- Spheroidal Head: For quickly alleviating pain in larger muscle areas.
- Node/Point Type: For partial body pains and localized acupoints.
- Dome/Facial Type: For superficial therapy and facial beautification/toning [1, 3].
- Automatic Acupoint Detection: High-end versions can detect areas of low electrical resistance on the skin, helping the user find the exact "trigger point" for effective relief [2].
- Portable & Battery Powered: Typically runs on a single AA battery or is USB-rechargeable, making it easy to use at the office, home, or while traveling [1, 2].
- Multi-Purpose Use: Effective for temporary relief of acute and chronic physical pain caused by arthritis, rheumatism, osteoporosis, sciatica, and sports injuries [3, 4].
