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.

Immediate relief - offloading has let me continue to play pickleball while my knee heals
Immediate relief - offloading has let me continue to play pickleball while my knee heals. I have had a long battle starting with miniscus surgery and cortisone and PRP shots - the brace is the only thing that has given me relief.
