Plantar fasciitis is among the most common causes of foot pain and affects athletes, active adults, workers who spend prolonged periods standing, and individuals with underlying biomechanical stress factors. Although often described as heel pain, the condition can become substantially more disruptive than its simple name suggests.

Most patients improve with conservative management. However, a subset develops persistent symptoms despite interventions such as stretching programs, orthotics, physical therapy, anti-inflammatory medications, injections, or other treatments.

A 2012 publication by Brook, Dauphinee, Korpinen, and Rawe in the Journal of Foot and Ankle Surgery evaluated wearable pulsed radiofrequency electromagnetic field (PRFE) therapy in patients with plantar fasciitis. The study enrolled 70 subjects and compared active treatment with placebo controls.

Study Design

  • diagnosed plantar fasciitis
  • randomized to active or placebo treatment
  • instructed to wear the device overnight
  • recorded pain scores using visual analog scales

Investigators focused on one particularly relevant endpoint: morning pain, often considered a hallmark symptom of plantar fasciitis and one of the most common patient complaints.

Study Findings

“The study group using the active PRFE device showed progressive decline in morning pain.” — Brook et al.

Day-7 morning pain scores were approximately 40% lower than baseline measurements within the active treatment group. The authors concluded that PRFE therapy worn nightly appears to offer a simple, drug-free, noninvasive therapy to reduce pain associated with plantar fasciitis.

“Mobility is foundational. Patients frequently describe outcomes in simple terms — walking farther, standing longer, or being able to participate in daily activities again.”

“Many chronic conditions involve repeated cycles of irritation and recovery. Understanding how therapeutic signals influence those cycles may become increasingly important.”
Nev Zubcevik, DO — Co-founder, Electrome

Important Context

Additional larger randomized studies remain valuable, and treatment decisions should always incorporate physician guidance and individual patient circumstances.

“The future opportunity is building systems that continuously improve from real-world use rather than treating every interaction as isolated.”
