INTRODUCTION TO HVPS • Recognised by various different names – HVPG, HVS, DC • MONOPHASIC, TWIN PEAK WAVEFORM • Fixed duration in microsecond range (upto 200µs) • Voltage should be greater than 100V. HISTORY • Originally developed in 1945 by Haslip in the USA and called 'Dyna-wave neuromuscular stimulation. • Used for -acute sprains and strains. -Lower back pain. -Phantom limb pain • The first published paper on use of this current was by Young in 1966, on edema reduction. • Commercially available in the mid1970s. • Some authors include it in the Microcurrent group. • Primarily used ...
Slideshow Project DOI:10.1682/JRRD.2011.11.0220JSP • Aim –Investigate alterations in body composition variables and spasticity following subtetanic neuromuscular electrical stimulation (NMES) training in adults with spinal cord injury (SCI). • Relevance –Skeletal muscle atrophy and development of spasticity are two common sequelae of SCI.

Slideshow Project DOI:10.1682/JRRD.2011.04.0068JSP • Aim –Determine whether: • Force produced by voluntary effort and functional electrical stimulation (FES) add together independently of effort, or • Increment in force depends on level of voluntary effort. • Relevance –FES may augment functional arm and hand movement poststroke. –Poststroke neuroprostheses incorporating voluntary effort and FES must consider how forces combine in order to provide appropriate level of stimulation. This article and any supplementary material should be cited as follows: Makowski P, Knutson J, Chae J, Crago P. Interaction of poststroke voluntary effort and functional neuromuscular electrical ...
Functional Electrical Stimulation • Implantable stimulators for neuromuscular control are the technologically most advanced versions of functional electrical stimulators. • Their function is to generate contraction of muscles, which cannot be controlled volitionally because of the damage or dysfunction in the neural paths of the central nervous system (CNS). BME 312-BMI II-L5- AL IIN 2014 • Their operation is based on the electrical nature of conducting information within nerve fibers, from the neuron cell body (soma),along the axon, where a travelling action potential is the carrier of excitation. • While the action potential is naturally generated chemically in the ...
