Healthcare Providers: Prescribing PEMF
Clinical Validation
PEMF is supported by decades of research ranging from basic science to randomized controlled trials. While protocols and outcomes vary by indication and device parameters, key themes are consistent:
-
Osteoarthritis (e.g., knee/hand): RCTs and meta-analyses show PEMF can reduce pain scores (e.g., VAS/WOMAC) and stiffness and improve function versus sham, particularly over multi-week courses.
-
Post-operative / post-injury edema & pain: Trials report reductions in swelling and analgesic requirements when PEMF is added to standard protocols, with favorable tolerability.
-
Tendinopathy/overuse syndromes: Studies demonstrate modest-to-meaningful improvements in pain and patient-reported function when combined with exercise therapy.
-
Bone biology precedent: PEMF’s long clinical history in bone growth stimulation supports its safety profile and bioelectric rationale.

Patient Selection
Appropriate when you want a non-pharmacologic adjunct to PT, activity modification, bracing, cryotherapy/heat, or analgesics:
-
Common use cases: osteoarthritis flares, post-operative or post-injury edema, chronic tendinopathy, myofascial pain, low-back/neck strain, overuse syndromes.
-
Good candidates: patients seeking drug-sparing options, intolerance to NSAIDs, or limited by comorbidities; motivated home-therapy users.
-
Use with rehab: pairs well with graded exercise and manual therapy.

Contraindications, Warnings & Adverse Effects
-
Do not use over or near implanted electronic devices (pacemaker, ICD, neurostimulator, infusion pump).
-
Avoid use during pregnancy, over known malignancy in the treatment area, active infection, open wounds at the site, or areas of impaired perfusion unless cleared by the treating clinician.
-
Precautions: impaired sensation, severe peripheral vascular disease, or patients unable to report discomfort—monitor closely.
-
Common AEs: rare and usually mild (transient warmth, skin irritation from garments). Discontinue if discomfort or irritation occurs.

Dosing & Protocol (Typical Clinical Patterns)
-
Session length: 60 minutes per treatment area (device turns off automatically)
-
Frequency: 2-3 sessions/day during acute phase; lower usage as symptoms improve.
-
Placement: center the device over the most symptomatic region (e.g., medial joint line in knee OA; paraspinal region for lumbar strain).
-
Adherence: encourage consistent daily use during the initial phase; can be combined with active rehab.
