Low Frequency Electrotherapy Device: Unique Waveform Output to Relieve Patient Pain!

With the fast pace of modern life and increasing work pressure, chronic pain, muscle strain, and cervical spondylosis have become problems that plague many people. Globally, chronic pain affects approximately 20% of the population, significantly reducing patients' quality of life. Faced with this health challenge, national healthcare strategies are gradually shifting towards a model that emphasizes both prevention and treatment. Physical therapy equipment, due to its non-invasive and non-surgical advantages, is increasingly favored by the medical community and policymakers.

Against this backdrop, low-frequency therapy is becoming an important tool in modern medicine and health management, bringing new hope to a large number of patients with chronic pain.

Part 1: Current Status and Technological Advances in Pain Rehabilitation

Traditional Pain Treatment

Traditional pain treatment mainly relies on medication, but its effectiveness is often limited and accompanied by significant side effects. Non-pharmacological therapies, such as acupuncture, also face accessibility limitations.

In recent years, with the development of biomedical engineering technology, low-frequency therapy technology has continuously improved in functionality, achieving significant breakthroughs in user experience and personalized treatment.

Low-frequency therapy, through its unique waveform output, electrically stimulates nerves and muscles, suitable for soft tissue and osteoarthritis analgesia, anti-inflammation, relieving muscle tension, and improving blood circulation.

Scientific research provides solid theoretical support for low-frequency therapy technology: A study published in September 2025 by Han Qingjian's team at the Fudan University Brain Science Institute systematically revealed for the first time the detailed neural mechanism of transcutaneous electrical nerve stimulation (TENS) analgesia, providing important insights for optimizing clinical treatment plans.

As medical research continues to deepen, the treatment mechanism of low-frequency therapy devices is receiving increasingly clear scientific explanations, and its clinical value is becoming increasingly prominent. Researcher Han Qingjian from Fudan University emphasized that their research not only expanded the understanding of the mechanism of action of TENS, but also provided important insights for optimizing clinical treatment plans and developing novel analgesic drug targets.

Principle Breakthrough

For a long time, the scientific community has generally believed that the analgesic mechanism of TENS (Transcutaneous Electrical Nerve Stimulation) can be attributed to the classic "spinal cord gate control theory" in pain research.

However, recent research from Fudan University has discovered a more complex mechanism: Transcutaneous electrical nerve stimulation (TENS) selectively activates glutamatergic neurons (DCNGlu) in the dorsal column nucleus by activating Aβ low-threshold mechanoreceptors (Aβ-LTMR) in the dorsal root ganglion (DRG). These DCNGlu neurons project to specific types of glutamatergic neurons (VPLDCN, Glu) in the ventroposterolateral nucleus of the thalamus, a region distinct from neurons receiving input from the dorsal horn of the spinal cord (VPLSDH, Glu). VPLDCN, Glu neurons form monosynaptic connections with layer 5 neurons in the somatosensory hindlimb cortex (S1HL), thereby mediating the analgesic effect induced by TENS.

This discovery not only explains the sustained analgesic effect of low-frequency therapy but also provides direction for the technological optimization of the device.

The XY-α-TRON-II Low-Frequency Therapy Device integrates several innovative technologies, including:

√ Transcutaneous Electrical Nerve Stimulation (TENS) mode: An electrotherapy method that emerged in the 1970s, known for its effectiveness in pain relief.

√ α-TRON electrical stimulation mode: Provides a gentle yet powerful sensation, long-lasting analgesia, and a lingering stimulation sensation even after treatment.

√ TENS + α-TRON combination mode: Dynamically varied stimulation helps overcome tissue tolerance.

√ Four-channel output: 4 adsorption electrodes + 4 flat electrode channels, multi-channel design, independent operation, no interference, and improved efficiency.

√ Multiple adsorption modes: High-grade adsorption electrodes are soft and comfortable, equipped with continuous, intermittent, and alternating adsorption modes, and also features cupping functionality.

The combination of these core technologies enables the low-frequency therapy device to provide more personalized treatment plans in clinical applications, meeting the diverse needs of different patients.

Low-frequency therapy, as a non-invasive physical therapy, is becoming an important part of the comprehensive treatment of chronic pain, and is expected to bring benefits to more patients, while also providing medical institutions with new treatment options.
