27.12 MHz Carrier
ActiPatch uses a precisely tuned 27.12 MHz electromagnetic carrier in the Industrial, Scientific, and Medical band. The same frequency used in pulsed shortwave therapy research for decades.
ActiPatch® is an over-the-counter FDA-cleared device built on pulsed shortwave therapy, a nonthermal form of electromagnetic therapy used as an adjunct in the treatment of musculoskeletal pain. No drugs, no electrodes or gels. Wear directly on the skin with the included tape or a wrap, or over a thin layer of clothing; avoid thick fabric.
ActiPatch uses pulsed shortwave therapy (PSWT), a nonthermal form of pulsed electromagnetic field therapy. PSWT modulates cellular signaling associated with inflammation and pain, all without electrodes, gels, or any sensation during use.

PSWT operates at energy levels below any thermal effect. There is no heat, no warming sensation, and no perceptible feedback during use. The therapy fits comfortably into daily wear.
There are no electrodes, no gels, and no skin prep. Wear it directly on the skin with the included tape or over a thin layer of clothing.
ActiPatch holds FDA 510(k) K192234 clearance for over-the-counter (OTC) adjunctive treatment of musculoskeletal pain. Clearance is not FDA approval.
Pulsed shortwave therapy is supported by decades of peer-reviewed research across multiple chronic pain indications. Below is a conservative summary of the published clinical literature relevant to ActiPatch.
A double-blind, sham-controlled randomized trial in knee osteoarthritis (Bagnato et al., Rheumatology 2016) reported pain and function improvements in its study population. Its findings do not guarantee an individual result.
A double-blind, placebo-controlled trial in plantar fasciitis (Brook et al., J Foot Ankle Surg 2012) reported a significant reduction in first-step morning heel pain versus placebo.
A UK chronic-pain registry (Rawe & Kotak, Pain Management 2015) describes self-reported outcomes. As an observational registry without a sham comparison, it cannot by itself establish a treatment effect.
FDA 510(k) clearance is based on substantial equivalence to legally marketed devices, not on an efficacy review. We say "supported by clinical evidence" because that reflects what the published literature shows.
Evidence is not interchangeable across devices. The knee osteoarthritis and plantar fasciitis studies above should be read alongside their study designs and limitations; the registry relies on self-report without a sham control. These sources do not establish superiority over TENS. For source details, see the publications library and the knee osteoarthritis evidence hub.
Individual results may vary. ActiPatch is intended for adjunctive use alongside your current care plan. Consult your healthcare provider before starting any new therapy.
TENS and PSWT are fundamentally different therapeutic technologies that use different forms of energy delivery, treatment models, and clinical workflows. This comparison describes how they are used, not a head-to-head efficacy finding or a reason to replace prescribed care.

ActiPatch was built to disappear into your routine. Wearable, drug-free, and continuously active for up to 720 hours per device.
Lightweight and low profile, with up to 720 hours of therapy per device. Wear it continuously day and night, or in stretches with breaks, at rest or in motion.
Wear it and go, with nothing to connect or manage. Place it over the painful area, switch it on, and continue with your day.
Drug-free pain support that works alongside, not in place of, your current care plan. Talk with your provider about integrating ActiPatch into your routine.
Put the science to work. ActiPatch® is FDA 510(k)-cleared, non-opioid, and built for flexible wear, continuously or as needed. It is available over-the-counter for adjunctive treatment of musculoskeletal pain, including heel pain associated with plantar fasciitis.
