Pulsed electromagnetic field treatment enhances healing callus biomechanical properties in an animal model of osteoporotic fracture

Research RF Safe Research Library Jan 1, 2014

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…

Effect of radiofrequency microtenotomy on degeneration of tendons: an experimental study on rabbits.

Research RF Safe Research Library Jan 1, 2014

This experimental rabbit study evaluated radiofrequency microtenotomy (Rf-mt) in prostaglandin E1-induced Achilles tendon degeneration. Rf-mt increased vascularity based on histopathology and immunohistochemistry. However, the authors report no significant difference in tendon healing compared with a sham-control…

No influence of acute RF exposure (GSM-900, GSM-1800, and UMTS) on mouse retinal ganglion cell responses under constant temperature conditions.

Research RF Safe Research Library Jan 1, 2014

This double-blind in vitro study exposed isolated mouse retinae to GSM-900, GSM-1800, and UMTS RF-EMF at SARs up to 20 W/kg while maintaining constant temperature. Changes in retinal ganglion cell responses to light stimuli were compared before, during, and up to 35 minutes after exposure. The authors report no…

The alteration of spontaneous low frequency oscillations caused by acute electromagnetic fields exposure.

Research RF Safe Research Library Jan 1, 2014

This double-blind, randomized, crossover study examined whether 30 minutes of near-field LTE radiofrequency exposure near the right ear alters resting-state brain activity measured by fMRI. The authors report decreased ALFF in multiple temporal and frontal/paracentral regions after real exposure compared with sham,…

Whole brain EEG synchronization likelihood modulated by long term evolution electromagnetic fields exposure.

Research RF Safe Research Library Jan 1, 2014

This conference paper examined whether LTE radiofrequency EMF exposure affects whole-brain EEG functional connectivity. Ten participants completed a crossover, double-blind real versus sham exposure protocol with 30 minutes of exposure per session while 32-channel EEG was recorded. Using synchronization likelihood,…

Effect of Extremely Low Frequency Electromagnetic Field and GABAA Receptors on Serum Testosterone Level of Male Rats.

Research RF Safe Research Library Jan 1, 2013

This animal experiment tested whether extremely low frequency electromagnetic field (ELF-EMF) exposure interacts with GABAA receptor modulation to affect serum testosterone in male rats. Rats were exposed for 30 days (8 hours/day) or sham exposed, then given saline, a GABAA antagonist (bicuculline), or a GABAA…

Are media warnings about the adverse health effects of modern life self-fulfilling? An experimental study on idiopathic environmental intolerance attributed to electromagnetic fields (IEI-EMF).

Research RF Safe Research Library Jan 1, 2013

This randomized experiment tested whether a TV report warning about WiFi health effects could influence symptoms during a subsequent sham WiFi exposure. Over half of participants reported symptoms attributed to the sham exposure, and the warning film increased EMF-related worries. Among participants with higher…

Pulsed radiofrequency in peripheral posttraumatic neuropathic pain: A double blind sham controlled randomized clinical trial.

Research RF Safe Research Library Jan 1, 2012
