Large TENS Pads for Back Pain | Butterfly & Lumbar Electrodes (OEM)
Large surface area electrode pads designed for back pain relief. Features butterfly and rectangular shapes for maximum lumbar coverage. Low-impedance carbon film (<80Ω) for even current distribution across large muscle groups.
Product Overview
Treating back pain requires more than a standard electrode. The lower back (lumbar) and mid-back areas consist of large, dense muscle groups that require wider coverage and stable current delivery to achieve effective pain relief.
TOP-RANK Electrical Pads for Back Pain are engineered specifically for these high-demand applications. Unlike standard 2x2" pads that concentrate current in a small spot, our Large Surface Electrodes disperse therapeutic energy over a wider area.
This "Wide-Dispersion" design does two things:
- Covers the Pain Zone: A single Butterfly or Large Rectangle pad can cover the entire lumbar region or spinal muscle group.
- Increases Comfort: By spreading the current, we reduce the "biting" sensation on the skin, allowing users to tolerate higher intensity settings needed for effective back muscle relief.
Why Size & Shape Matter for Back Pain
For OEM clients targeting the "Back Pain" market, offering the right shape is a key differentiator.
1. The "Butterfly" Advantage
Our specialized Butterfly shape is designed to conform to the curvature of the lower back.
- Ergonomics: The contoured center fits over the spine, while the wide "wings" target the paraspinal muscles on both sides.
- Cost-Efficiency: One large butterfly pad can replace 2 or 4 smaller standard pads, simplifying application for the patient.
2. Large Rectangles (High Coverage)
We manufacture extra-large rectangular pads (e.g., 5x9cm, 7x12cm, or 10x15cm).
- Application: Ideal for the latissimus dorsi (upper back) or broad lower back coverage.
- Adhesion Stability: The larger surface area provides a stronger grip, preventing the pad from peeling off when the patient bends or twists.
3. Optimized Current Delivery (Low Impedance)
Back muscles are dense. To treat them effectively, you need an electrode that minimizes resistance. We use a Low-Impedance Carbon Film (< 80 Ω) that ensures the electrical pulse is delivered efficiently without losing energy at the skin interface. This allows for smoother, more effective stimulation of large muscle groups.
