Published studies on pulsed electromagnetic field (PEMF) therapy for osteoarthritis, including some that focus on the thumb carpometacarpal (CMC) joint and others with broader scope:
Systematic Reviews & Meta-Analyses
A 2020 meta-analysis found statistically significant improvements in pain, stiffness, and physical function with PEMF therapy compared to placebo. Pain reduction had a standardized mean difference (SMD) of 1.06, indicating a strong effect.
A 2024 systematic review of 17 randomized controlled trials (1,197 patients) reported a 60% decrease in pain and 42% improvement in WOMAC scores for knee osteoarthritis. Treatment durations ranged from 15 to 90 days.
Mechanism-Based Research
A 2025 study showed that PEMF therapy inhibits the NF-κB pathway and activates Sirt1, reducing inflammation and preserving cartilage in osteoarthritis models.
PEMF was found to increase chondrocyte proliferation and extracellular matrix production, which may help repair damaged cartilage3.
Thumb CMC Arthritis-Specific Insights
While direct published results for thumb CMC PEMF therapy are still pending (as in the Stanford trial), other studies suggest that manual therapy and therapeutic exercise can improve pain and function in this joint.
A randomized trial combining joint mobilization and neural mobilization showed better pain outcomes than sham treatment, though strength improvements were limited.
Comparative Trials
A 2023 randomized trial comparing PEMF to low-level laser therapy (LLLT) for knee OA found PEMF to be more effective in reducing pain during rest and activity, and improving functional scores like WOMAC and timed up-and-go tests.
ActiPatch® was used in several PEMF therapy studies, particularly those focused on musculoskeletal pain and osteoarthritis:
Knee Osteoarthritis
A double-blind, placebo-controlled trial published in Rheumatology (Oxford) tested a wearable PEMF device (ActiPatch) in 66 patients with knee OA.
Results showed significant reductions in pain (VAS score) and improved WOMAC scores.
26% of ActiPatch users discontinued NSAIDs or analgesics due to symptom relief.
Large-Scale Registry Study
BioElectronics Corporation conducted a 7-day trial program with over 44,000 users across the UK and Ireland.
Among 5,000 chronic pain sufferers who submitted assessments:
65% reported 57% average pain reduction
67% of opioid users reduced or eliminated medication
84% reported improved quality of life
93% confirmed long-term effectiveness
Plantar Fasciitis
A multicenter, double-blind trial showed overnight ActiPatch use significantly reduced heel pain.
Published in the Journal of Foot and Ankle Surgery.
Postoperative Pain
A Tufts University study evaluated ActiPatch for postoperative edema and pain after wisdom tooth extraction.
Though the trial was terminated early, it aimed to compare ActiPatch vs. placebo for swelling and pain relief.
ActiPatch has been actively studied and shows promising results across multiple conditions.
How does ActiPatch compare to other PEMF devices?
ActiPatch stands out among PEMF (Pulsed Electromagnetic Field) devices for its simplicity, affordability, and wearability, but it’s not the only player in the game. Here's how it stacks up against other popular PEMF options:
ActiPatch ($30–$50)
Type: Wearable, low-intensity PEMF device
Frequency: 1 kHz pulses at 27.12 MHz
Intensity: Very low (microtesla range)
Use Case: Chronic pain, arthritis, plantar fasciitis
Pros:
FDA-cleared for musculoskeletal pain
Affordable and easy to use
Long battery life (up to 720 hours)
Cons:
Limited intensity and depth of penetration
Disposable after battery life ends
FlexPulse ($500–$700)
Type: Localized PEMF device with multiple programs
Frequency Range: 0.5 Hz to 100 Hz
Intensity: Up to 300 Gauss
Pros:
Multiple frequency programs for different conditions
Rechargeable and portable
Stronger field for deeper tissue penetration
Cons:
Higher cost
Requires some setup and understanding of programs
Oska Pulse ($300–$400)
Type: Wearable PEMF device with a single automated program
Frequency: Varies through four healing stages
Intensity: ~9 Gauss
Pros:
Simple one-button operation
Targets inflammation, blood flow, pain, and healing
Medical device registration in multiple countries
Cons:
Lower intensity than FlexPulse
More expensive than ActiPatch
NeoRhythm ($300–$400)
Type: Head-worn PEMF device focused on neurological health
Use Case: Sleep, focus, meditation
Pros:
App-controlled with multiple brainwave programs
Innovative design for cognitive support
Cons:
Less suitable for musculoskeletal pain
Comfort issues during sleep
Bottom Line: ActiPatch is a great entry-level option for localized pain relief, especially if you're looking for something simple and budget-friendly. But if you need deeper tissue penetration, customizable programs, or neurological support, other devices like FlexPulse or NeoRhythm might be worth the investment.
