Md. Mcpartland et Dj. Mook, A ROBUST TRANSCUTANEOUS ELECTRO-MUSCLE STIMULATOR (RTES) - A MULTIMODALITY TOOL, Medical engineering & physics, 17(4), 1995, pp. 314-318
This paper introduces a transcutaneous electrco-muscle stimulator desi
gn that has a wide range of output capabilities. Because of this, the
unit is referred to as a robust transcutaneous electro-muscle stimulat
or (RTES). The RTES is a constant current stimulator that is designed
to be capable of generating significant tetanic contractions from larg
e muscle groups, such as the quadriceps. It is capable of generating c
omplex current pulse profiles and has been tested at pulse frequencies
greater than 7500 Hz. It is routinely used to generate rectangular, b
i-phasic pulses in muscle-modelling studies in ranges of widths from 3
to 1000 mu s, amplitudes from -50 to +50 mA and frequencies from 10 t
o 60 Hz. The design extrema on pulse width and amplitude, are 1000 mu
s and +/-100 mA respectively. Because of the stimulator's robust outpu
t characteristics, it is suitable for many types of electro-stimulatio
n studies including pain management, edema reduction and more.
