This in vitro study compared continuous versus intermittent 16 Hz ELF-PEMF exposure strategies in osteoprogenitor (SCP-1) cells. Intermittent exposure (10 min every 8 h) was reported to enhance cell numbers and osteogenic function relative to continuous daily exposure (30 min every 24 h). The authors report increased…

This study reports a noninvasive pulsed-burst electromagnetic field (PEMF) approach intended to protect against radiotherapy-induced bone loss. A 15 Hz, 2 mT PEMF waveform is described as producing distinctive calcium oscillations in osteoblasts and inhibiting radiation-related bone loss while not affecting other…

This in vitro study reports that a single pulsed electromagnetic field (0.2 Hz) increased expression of tenogenic genes and reduced expression of a matrix-degradation/inflammatory gene (Mmp1) in tendon cells. After 5 days of exposure (3 min/day), collagen type I and total collagen synthesis protein levels were…

This in vitro study compared commonly used pulsed electromagnetic field (PEMF) exposures with electromagnetic fields tuned to satisfy the ion cyclotron resonance (ICR) condition for calcium. After 3 weeks, the calcium ICR condition was associated with increased glycosaminoglycans and type II collagen synthesis and…

This in vitro study exposed rat adipose-derived stem cells to a pulsed electromagnetic field (7 Hz, 30 mT) and assessed viability by flow cytometry. The authors report that a low-fat diet was protective in PEMF-exposed ADSCs, especially in pups. They also report a higher proportion of early apoptotic cells in…

This in vitro study exposed rat calvarial osteoblasts to 50 Hz, 0.6 mT pulsed electromagnetic fields for 1.5 hours and measured early differentiation-related markers over 0–12 hours. The abstract reports increased ALP activity at 3 hours and time-dependent changes in ALP, Runx2, and OSX transcription and Runx2/OSX…

This double-blind randomized placebo-controlled trial evaluated pulsed electromagnetic field (PEMF) therapy followed by a standardized shoulder strengthening exercise program in adults with shoulder impingement syndrome (N=56). The active PEMF group improved in pain and function from baseline across follow-ups, while…

This animal study evaluated whether daily pulsed electromagnetic field (PEMF) treatments improve delayed fracture healing in skeletally mature ovariectomized (OVX) rats. By 6 weeks, PEMF-treated rats showed improved hard callus elastic modulus and radiographic evidence of better callus bridging compared with sham…

This open case study assessed transcranially applied pulsed electromagnetic fields (PEMF) as a potential therapy for multiple chemical sensitivity (MCS) in three patients. Two of three patients reported considerable improvements in MCS-related symptoms/functional impairments and reduced capsaicin-induced secondary…

This preliminary prospective clinical trial compared pulsed electromagnetic field stimulation (PEMF) and low intensity laser irradiation (LILI) as adjuncts to mandibular fracture repair assessed by clinical union and radiodensitometric bone density. Clinical outcomes (segment stability and occlusion) were…

This study compared two non-invasive acupoint stimulation methods—TEAS and PEMF—as alternatives to manual acupuncture for recovery from exercise-induced muscle fatigue. Using 2 Hz stimulation (PEMF magnetic flux 30.92 mT), the authors report faster recovery of EMG median frequency and improved peak torque recovery in…

This randomized, placebo-controlled, double-blind, cross-over trial evaluated a wrist-applied PEMF bracelet in 18 migraine patients and examined possible modulation of placebo effects. In the overall group, both PEMF and placebo were associated with similar reductions in migraine frequency and intensity. The authors…

This randomized controlled trial evaluated low-power, low-frequency pulsed electromagnetic field (PEMF) therapy at 600 Hz and 800 Hz as an adjunct treatment for diabetic polyneuropathy. Thirty participants were randomized to 600 Hz PEMF, 800 Hz PEMF, or usual medical treatment for 12 days. The abstract reports…

This randomized animal study tested whether pulsed electromagnetic field (PEMF)-induced vibration affects orthodontic tooth movement produced by magnetic and/or mechanical forces. Forty-four Wistar rats were exposed to PEMF-induced vibration or normal atmosphere while tooth movement was induced using magnets and/or…
