OrthoTens Wireless TENS Unit — FDA-Cleared Pain Relief with Bluetooth App Control
The OrthoTens Wireless TENS Unit (SM9187) is an FDA-cleared, Bluetooth-enabled TENS & EMS therapy device designed to quickly relieve back pain, sciatica, period pain, knee pain, shoulder pain, and neck pain — without pills or wires. Control every session directly from your smartphone using the free Dr. Stim app (iOS & Android).
How TENS 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.

Frequently Asked Questions
What conditions can a TENS unit 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 TENS therapy 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 TENS therapy relieve sciatica 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 TENS and EMS therapy?
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 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.

I ordered tens with app
I ordered tens with app. Getting the app to work was not easy! The tens is rather mild. Not complaining, it works, but my pain is so bad it really does not help it at all. But thank you for a handy tens that is easy to use, altho, recommend without app.

I have osteoarthritis in back would this help and what intensity is at highest level
OrthoTape.com
Hello. Yes this can definatly help with that condition. The settings can be adjusted up or down to the level of comfort you need. It has a high setting and depends on what level of intensity you prefer.
Not only can you swim and sweat, but its less itchy!
My son was devistated to break his arm and not be able to go swimming over the summer. But once he was switched from a long cast to a short cast and the doctor said he could have a waterproof one, we were ready with this product. Not only did it save our summer by allowing him to swim, he was also able to clean his cast out in the bath after an especially hot and sweaty soccer practice. However, drying the cast out is a pain in the butt.
But most importantly to me, he complained about being itchy far less and his skin looked completely clean and normal once the cast was removed, other than being pale. When his non-waterproof long cast was removed he had a nasty rash that wasnt medically concerning but made him very itchy and took a few days to clear.
