This 4-pack is compatible with both the SM9187 (app-controlled) and SM9187-S (manual control) wireless TENS unit models, as well as a wide variety of other wireless TENS units on the market that use the same standard snap spacing.
Electrode pads lose adhesion and conductivity over time with regular use. Replacing them regularly ensures consistent electrical contact, optimal therapy intensity, and hygienic use — especially important when sharing a device between users.

Replace your gel electrode pads when you notice any of the following:
For regular daily users, replacing pads every 4–6 weeks is recommended to maintain optimal therapy performance.
Your OrthoTens reusable electrode pads can last through dozens of sessions with proper care. Washing them after each use restores adhesion and keeps them hygienic. Follow these 3 simple steps:
| Step | Action | Details |
|---|---|---|
| Remove Debris | Gently clean the gel side | Use your fingertip or a damp cloth to remove lint, skin oil, and debris from the gummy adhesive surface. |
| Rinse | Rinse the gel side with water | Hold the gel side under cool running water to flush away loosened residue. Do not submerge or soak the pad. |
| Dry Before Reuse | Air dry for 12 hours | Pat excess moisture from the backing, then lay gel-side up and air dry for at least 12 hours. Never use heat (hair dryer, oven, direct sunlight) — heat destroys the gel adhesive. |
💡 Pro tip: Store cleaned, dry pads gel-side down on their original plastic backing or a clean non-porous surface to preserve stickiness between sessions.
⚠️ SAFETY NOTICE: Do not use electrode pads on broken, irritated, or infected skin. Patients with electronic implants such as a pacemaker should not use TENS therapy devices. Consult your physician before use if you have any underlying medical conditions.

Gently clean the gel side to remove lint and oil, rinse under cool running water, then pat dry and air dry gel-side up for at least 12 hours before reuse. Never use heat to dry. Store pads gel-side down on their plastic backing between sessions. Replace when they no longer adhere firmly to the skin.
With proper cleaning and storage, reusable TENS gel pads typically last 20–30 sessions or more. Washing after each use and allowing a full 12-hour air dry significantly extends their lifespan. Replace pads when they no longer adhere firmly to the skin — poor adhesion reduces therapy effectiveness.
Yes. These replacement pads are designed specifically for the OrthoTens SM9187 (app-controlled) and SM9187-S (manual control) wireless TENS units. They use a standard 1⅛" snap spacing and will also fit many other wireless TENS units on the market that use the same snap distance.
With proper care, reusable gel electrode pads typically last 20–30 uses. To extend pad life, clean the skin before each session, store pads on their protective film after use, and avoid exposing them to excessive heat or direct sunlight. Daily users should plan to replace pads every 4–6 weeks.
These pads can be placed on most muscle groups including the lower back, upper back, shoulders, knees, and abdomen. Do not place electrode pads on the head, spine, throat, or over broken or irritated skin. Always follow the placement guidelines in your OrthoTens device manual.
No. The black and white variants are identical in function and performance. The color options are purely cosmetic so you can match your electrode pads to your OrthoTens device color (SM9187-WH white or SM9187-BK black).
