On the Nature and Elimination of Stimulus Artifact in Nerve Signals Evoked and Recorded Using Surface Electrodes
The electrical stimulus pulse and the surface electrodes commonly used to study compound action potentials of peripheral nerves give rise to an artifact consisting of an initial spike and a longer lasting tail which often interferes with the recorded signal. Expand
Age‐related changes in peripheral and central nerve conduction in man
Somatosensory evoked potential (SEP) latencies, motor and sensory nerve conduction velocities (CVs), and F-wave latenies were measured in 15 elderly normal subjects (mean age 74.1 years), and theExpand
Automatic Decomposition of the Clinical Electromyogram
We describe a new automatic signal-processing method (ADEMG) for extracting motor-unit action potentials (MUAP's) from the electromyographic interference pattern for clinical diagnostic purposes. Expand
Nerve fiber conduction-velocity distributions. II. Estimation based on two compound action potentials.
A method is presented for estimating nerve fiber conduction velocity distributions from non-invasive measurements of the compound action potential at two distinct locations separated by a knownExpand
Motor unit firing rates and firing rate variability in the detection of neuromuscular disorders.
We have used automatic decomposition electromyography (ADEMG) to study 41 muscles in 29 patients with well-defined peripheral and central motor disorders. In motor neuron diseases motor unit actionExpand
Nerve fiber conduction-velocity distributions. I. Estimation based on the single-fiber and compound action potentials.
A method is described for estimating the distribution of nerve-fiber conduction velocities in a nerve bundle. This method is based on a detailed general model of the nerve bundle compound actionExpand

A method is described for deriving an indirect estimate of the velocity of impulse propagation in the spinal cord of intact man. The estimate is computed from measurements of motor and sensory nerveExpand

  • 1 January 1984
Recent advances in digital signal processing have permitted the development of clinically relevant, noninvasive, computer‐based methods for estimating the distribution of conduction velocities (DCV) in motor, sensory, and mixed populations of large myelinated nerve fibers. Expand
