ActiPatch vs TENS: How Are They Different?

What does each device actually deliver?

TENS means transcutaneous electrical nerve stimulation. A typical TENS setup places adhesive electrode pads on the skin and sends a controlled electrical current between them. The user often adjusts intensity and may notice a tingling sensation. Exact settings and wear instructions depend on the particular model, so the manufacturer’s directions matter more than a generic comparison chart.

ActiPatch uses pulsed shortwave therapy (PSWT). It emits a 27.12 MHz radiofrequency carrier in pulses rather than sending a current through two electrode pads. The field is nonthermal and sub-sensory at its designed output: you should not expect the buzzing familiar from many TENS systems. A lack of sensation does not, by itself, establish that pain relief has or has not occurred.

How do placement and wear differ?

For ActiPatch, position the loop over the painful musculoskeletal area. Secure it directly 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. The loop can be repositioned when you change activities; always follow the supplied package instructions, particularly for warnings and placement.

TENS generally needs its electrodes to contact skin for electrical stimulation. Electrode position and treatment-session length vary by device and purpose. If you already use TENS under a clinician’s instructions, do not change that treatment plan based on a comparison article. Likewise, do not place ActiPatch over an implanted electronic device.

What about therapy time and day-to-day use?

One ActiPatch provides 720 therapy hours. Continuous operation uses those hours in roughly 30 days; turning it off between uses extends the calendar time over which you can use the available operating hours. The integrated CR2032 battery is not designed for replacement or charging. Keep the device dry and take it off before showering, bathing or swimming.

Many TENS products are designed around timed sessions, removable pads and adjustable settings. Some systems are wearable for longer periods, so no single duration applies to all TENS units. Compare a specific product’s manual rather than treating all TENS devices as identical. Consider whether you want a self-contained device or prefer adjustable electrical stimulation.

What does the research establish?

Published ActiPatch-related PSWT trials 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 investigated pain outcomes in their own study populations, not a head-to-head comparison with TENS. Observational registries can describe users’ reported experience but cannot establish comparative effectiveness.

FDA 510(k) clearance K192234 identifies the over-the-counter (OTC) adjunctive musculoskeletal-pain indication and substantial equivalence to a legally marketed predicate. It is not FDA approval and it does not prove that ActiPatch works better than TENS. Ask a clinician about new, severe or unexplained pain and about an appropriate approach alongside your existing care.

How should you decide?

Start with your own practical needs and the instructions for each device. If adhesive electrodes or adjustable sensations are important to you, those are considerations for TENS. If you prefer a device with no electrode leads and a preset operating pattern, ActiPatch offers a different workflow. Suitability also depends on your medical history and where you intend to wear the device.

If you have a pacemaker, ICD or another implanted electronic device, or are pregnant or think you may be pregnant, do not use ActiPatch. Read the package insert before use.
