Macro electromyography and motor unit number index in the tibialis anterior muscle: Differences and similarities in characterizing motor unit properties in prior polio

TLDR
It is shown that MUNIX can be used to characterize MUs with high reproducibility, even in a large muscle, and one of the reasons for this finding may be the difference in MU populations studied with the two methods.

How Long does Denervation Take in Poliomyelitis? Or is it a Lifetime?”

TLDR
It was showed that patients with a history of poliomyelitis experienced denervation with subsequent reinnervation for many years.

Macro electromyography, an update

TLDR
The value of combining macro EMG with single‐fiber EMG and conventional EMG recordings is discussed and an update of findings in some nerve–muscle disorders is updated.

Concentric needle EMG versus macro EMG I. Relation in healthy subjects

Motor unit characteristics in healthy subjects and those with postpoliomyelitis syndrome: A high‐density surface EMG study

TLDR
It is concluded that with HD‐sEMG it is possible to detect neurogenic motor unit changes noninvasively, both byAnalysis of the raw signal itself and by analysis of extracted single MUAPs.

Post‐poliomyelitis syndrome

TLDR
Although there is no specific treatment for PPS, an interdisciplinary management program can be useful in controlling symptoms and contributing factors may be aging, overuse, and disuse.

A SIMULATION STUDY ON NEUROMUSCULAR FACTORS AFFECTING CONSECUTIVE MOTOR UNIT ACTION POTENTIAL WAVESHAPE

TLDR
Simulation of pathological MUPs showed that it is useful for clinicians to understand the progress of a neuromuscular pathology and the factors affecting consecutive MUP wave shape.

Electrophysiology and electrodiagnosis of the post-polio motor unit.

TLDR
Electrodiagnostic studies--conventional electromyography, single fiber electromyographic studies (SFEMG), and macroelectromyography (macro-EMG)--that have provided information on the post-polio motor unit and on the possible etiology of some post-Polio syndrome symptoms are described.

Postpolio muscular atrophy. Diagnostic utility of macroelectromyography.

TLDR
It is concluded that low-amplitude macro-EMG signals may be useful in the identification of muscles weakened by postpolio muscular atrophy.

Scanning EMG in normal muscle and in neuromuscular disorders.

Disintegration of the motor unit in post-polio syndrome. Part I. Electrophysiological findings in patients after poliomyelitis.

TLDR
It seems that the reinnervation after acute polio is a continuing process and thus complete stabilization and integration of the motor unit cannot be achieved and chronic neurogenic changes of a similar degree were observed.

An 8‐year longitudinal study of muscle strength, muscle fiber size, and dynamic electromyogram in individuals with late polio

TLDR
Evidence of on‐going denervation/reinnervation as well as of failing capacity to maintain large motor units was demonstrated in subjects with polio 24 to 51 years prior to the first examination.

Morphologic changes in the muscles of patients with postpoliomyelitis neuromuscular symptoms

TLDR
It is concluded that postpolio muscle biopsies show a spectrum of morphologic changes that depend on whether the biopsied muscle was originally affected and had fully or partially recovered, and the newly weakened muscles show signs of recent denervation.

Use of single fiber EMG and macro EMG in study of reinnervation

TLDR
The use of single iber EMG and macro EMG in studies of reinnervation is discussed and the capacity for reinn conservation is discussed for a few conditions as well as factors that limit the reinnoration process.

Simulation of macro EMG motor unit potentials.

Assessment of variability in the shape of the motor unit action potential, the “jiggle,” at consecutive discharges

TLDR
Simulations showed that increased jitter of the constituent single fiber potentials increases the jiggle as expressed by an increase in CAD and decrease in CCC values, which will increase the information obtainable from routine EMG investigations.

Outliers, a way to detect abnormality in quantitative EMG

TLDR
The aim of the present investigation was to define limits of normal values and to compare the diagnostic yield of assessing definitely abnormal values outliers, with conventional mean values of MUP parameters, and found that outliers were as sensitive as mean values in neuropathies and better in myopathies.
