ActiPatch^® vs TENS: How Are They Different?

TENS means transcutaneous electrical nerve stimulation. A typical setup puts sticky electrode pads on the skin and sends a controlled electrical current between them. The user often adjusts the strength and may feel tingling. Settings and wear instructions depend on the model, so the maker's directions matter more than a general chart.

ActiPatch^® uses pulsed shortwave therapy (PSWT). It sends a 27.12 MHz radio-frequency signal in pulses instead of current between two pads. At its designed output the field is nonthermal and sub-sensory, so do not expect the buzzing of many TENS units. Feeling nothing does not tell you whether pain relief has or has not happened.

With ActiPatch^®, put the loop over the painful area. Hold it on skin with the included tape or a wrap, or place it over thin clothing such as a T-shirt or leggings. Avoid thick fabric between the device and skin. You can move the loop when you change activities. Follow the package instructions, especially for warnings and placement.

TENS electrodes generally need to touch skin. Where they go and how long each session lasts depends on the device and purpose. If you use TENS on a clinician's advice, do not change that plan because of a comparison article. Do not place ActiPatch^® over an implanted electronic device.

One ActiPatch^® provides up to 720 therapy hours. Running it nonstop would use them in at most about 30 days. Switching it off between uses spreads them over more days. This is arithmetic, not a guaranteed lifespan. The built-in CR2032 battery cannot be replaced or charged. ActiPatch^® is made for everyday wear, including activity and sweating, with IP22-rated water protection. Remove it before showering, bathing, or swimming.

Many TENS products are built for timed sessions, with removable pads and adjustable settings. Some can be worn longer, so no one length fits every TENS unit. Check a product's manual rather than treating all TENS devices alike. Think about whether you want a self-contained device or adjustable electrical stimulation.

Published ActiPatch^®-related PSWT studies include the double-blind, placebo-controlled knee pain study by Bagnato and colleagues in Rheumatology (2016) and the plantar fasciitis heel-pain study by Brook and colleagues in the Journal of Foot and Ankle Surgery (2012). They looked at pain in their own study groups. They did not compare ActiPatch^® with TENS. Registries describe what users report. They cannot show which option works better.

ActiPatch^® is FDA cleared (510(k) K192234) for over-the-counter adjunctive treatment of musculoskeletal pain, and can be used alongside other treatments. Clearance describes the cleared use. It does not show ActiPatch^® works better than TENS. Ask a clinician about new, severe, or unexplained pain, and about how to fit this in with your care.

Start with what you need and each device's instructions. If you want adhesive electrodes or adjustable sensations, those point toward TENS. If you want no electrode leads and a preset operating pattern, ActiPatch^® is a different way to work. Whether it suits you also depends on your medical history and where you plan to wear it.

Do not use ActiPatch^® if you have a pacemaker, ICD, or other implanted electronic device, or if you are or may be pregnant. Read the package insert first. You can read the research on our science page, then see the store listing. Neither replaces a personal clinical assessment.
