How TENS & EMS Therapy Works
TENS (Transcutaneous Electrical Nerve Stimulation) delivers gentle electrical pulses through reusable gel electrode pads placed on the skin. These pulses interrupt pain signals traveling to the brain and stimulate the release of endorphins — your body's natural painkillers. The OrthoTens SM9187 also includes EMS (Electrical Muscle Stimulation) modes to accelerate muscle recovery after workouts or injury, making it a true all-in-one TENS EMS combo unit.

♻️ How to Clean & Reuse Your TENS Electrode Pads — Extend Their Life with Proper Care
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.
🛒 Time to Replace Your Electrode Pads?
Even with perfect care, TENS electrode pads eventually lose their adhesion. When your pads no longer stick firmly to the skin, it's time for a fresh set — weak adhesion means weaker therapy signal and less effective pain relief.

Compatible replacement pads are available in our Electrotherapy collection. Stocking a spare set means your drug-free pain relief therapy is never interrupted.
Frequently Asked Questions
Does insurance cover a TENS unit? Can I use HSA or FSA?
This product is HSA/FSA eligible, so you can use pre-tax dollars to purchase it directly. If you have a high DME deductible (common with many insurance plans), you may actually pay less buying here than at your doctor's office — where the same device can cost $300–$500 or more. Many clinics also allow you to choose where you purchase your DME items. HCPCS code E0720 may apply — verify with your insurer before purchasing through your provider.
How do I clean and reuse my TENS electrode pads?
Gently clean the gel side to remove lint and oil, rinse with cool water to flush residue, 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. When pads no longer adhere firmly, replace them — replacement TENS electrode pads are available at OrthoTape.com.
How many times can I reuse TENS electrode pads?
With proper cleaning and storage, reusable TENS gel pads can 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.
Where can I buy replacement TENS electrode pads?
Replacement electrode pads compatible with the OrthoTens SM9187 TENS machine are available directly at OrthoTape.com — Electrotherapy Collection. We recommend keeping a spare set on hand so your therapy is never interrupted.
What conditions can a TENS machine help treat?
TENS therapy is clinically used for chronic lower back pain, sciatica, osteoarthritis, fibromyalgia, period cramps, post-surgical pain, and sports injuries. The OrthoTens SM9187 also includes EMS modes for muscle rehabilitation and recovery after exercise or injury.
Is a wireless TENS unit safe to use every day?
Yes, TENS therapy is generally safe for daily use. Most clinicians recommend sessions of 20–30 minutes, 1–3 times per day. Avoid placing electrode pads over the spine, head, or broken skin. Always consult your physician if you have an underlying medical condition before starting regular TENS therapy.
How does a TENS machine relieve sciatica and nerve pain?
Sciatica is caused by compression or irritation of the sciatic nerve, producing shooting pain from the lower back down the leg. TENS therapy works by sending low-voltage electrical pulses that block pain signals along the nerve pathway and stimulate endorphin release, providing temporary but meaningful relief during flare-ups. Place electrode pads along the lower back and upper gluteal region for best results.
Can I use a TENS unit for period pain (dysmenorrhea)?
Yes. TENS therapy is a well-documented, drug-free option for managing primary dysmenorrhea (period cramps). High-frequency TENS applied to the lower abdomen or lower back has been shown in clinical studies to significantly reduce menstrual pain intensity. The OrthoTens SM9187 includes dedicated programs suitable for abdominal and pelvic pain relief.
What is the difference between a TENS unit and an EMS unit?
TENS (Transcutaneous Electrical Nerve Stimulation) targets sensory nerves to block pain signals. EMS (Electrical Muscle Stimulation) targets motor nerves to cause muscle contractions, which helps rebuild strength, reduce atrophy, and accelerate recovery after injury or surgery. The OrthoTens SM9187 offers both modalities in a single wireless TENS EMS device.
What is your return policy for TENS units?
We accept returns within 60 days of purchase for items that are unused and in original condition. Because this is a medical device, we cannot accept returns on units that have been used. If your device has a manufacturing defect, please contact us — used units are covered under our 1-year manufacturer warranty.
