A six-pound battery-powered portable transcranial magnetic stimulator

Background Commercial transcranial magnetic stimulators are massive and may be difficult to transport for lecture and teaching purposes. Objective To design and construct a portable, battery-powered magnetic Stimulator of the lowest possible mass for use in demonstrations and simple measurements. Results The functioning battery-powered single-pulse system is relatively inexpensive, weighs less than 7 Pounds, including coil, incorporates external sync capability, and functions well for the intended purposes. Conclusions The device may Useful for teachers, researchers. and clinicians. (C) 2008 Elsevier Inc. All rights reserved.
