This study evaluated pulsed radiofrequency (PRF) neuromodulation of the suprascapular nerve in 11 patients with chronic shoulder pain from adhesive capsulitis and/or rotator cuff tear. Pain (VAS) and shoulder-related quality of life/function (OSS) were assessed before treatment and monthly after PRF for up to 9…
Peripheral pulsed electromagnetic fields may reduce the placebo effect in migraine patients that do not respond to the sham intervention in a randomized, placebo-controlled, double-blind, cross-over clinical trial.

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…
Human keratinocytes in culture exhibit no response when exposed to short duration, low amplitude, high frequency (900 MHz) electromagnetic fields in a reverberation chamber.

This in vitro study exposed normal human epidermal keratinocytes to non-thermal 900 MHz electromagnetic fields in a mode-stirred reverberation chamber under two short-duration conditions. Microarray analysis found only limited gene modulation (20 genes) with small expression ratios and no shared genes across…

Jan 1, 2010
This theoretical/physics paper examines how an in-plane uniform electric field affects the de Haas-van Alphen (dHvA) effect in graphene. It reports that magnetization, magnetic susceptibility, and dHvA oscillation behavior depend on a dimensionless parameter β = E/(vF B), with divergences described at a critical…

This Physical Review Letters paper reports magnetotransport measurements on a gated LaAlO3/SrTiO3 interface to assess the main effect of an applied gate electric field. The authors find that mobility changes dominate over sheet carrier density changes (mobility variation reported as nearly fivefold larger). They also…

Jan 1, 2008
This in vitro study reports that electric fields can control the velocity of microtubules gliding over a kinesin-coated surface. Assisting fields increased speed up to fivefold, while opposing fields slowed motion to zero, and sideways fields induced significant motion. The authors present a grab-and-release model to…
Surface-induced nonlinearities of liquid crystals driven by an electric field.

Jan 1, 2008
This experimental physics study examines how a static electric field affects the optical nonlinearity of methyl-red doped nematic liquid crystals. The authors report that low voltages below the Fredericks transition threshold can change the optical nonlinearity by orders of magnitude. They state that the data fit a…

Jan 1, 2008
This engineering-focused conference paper proposes figures of merit to evaluate deep-brain transcranial magnetic stimulation (dTMS) coil designs, focusing on depth penetration, scalp stimulation, focality, and energy. It analyzes circular crown and C-core coils and reports reduced electric-field attenuation with…
