Wireless TENS EMS Unit with Manual Control for Pain Relief

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.

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.

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.

Replacement electrode pads compatible with the OrthoTens SM9187-S TENS machine are available directly at OrthoTape.com — Electrotherapy Collection. We recommend keeping a spare set on hand so your therapy is never interrupted.

TENS therapy is clinically used for chronic lower back pain, sciatica, osteoarthritis, fibromyalgia, period cramps, post-surgical pain, and sports injuries. The OrthoTens SM9187-S also includes EMS modes for muscle rehabilitation and recovery after exercise or injury.

The SM9187-S uses manual on-device controls — no smartphone or Bluetooth app is required. This makes it ideal for users who prefer simplicity or do not want to manage a phone app during therapy. The app-controlled SM9187 model offers additional program customization via the free Dr. Stim app (iOS & Android) and Bluetooth connectivity.

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.

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-S includes dedicated programs suitable for abdominal and pelvic pain relief.

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.
