Respiratory Muscle Fatigue

Annals of Internal Medicine, 1988
Excerpt To the Editor:Murciano and colleagues (1) showed that tracheal occlusion pressure (P0.1) provided a better predictive index for successful extubation than classic weaning criteria in patien...

Muscle Fatigue and Muscle Injury

Physical Medicine and Rehabilitation Clinics of North America, 2000
The purpose of this review is to acquaint the reader with the neurobiology of muscle fatigue. Muscle fatigue is a complex, multifactorial process. The authors have covered the chain of events bringing about skeletal muscle contraction and the manner in which fatigue may affect each step.

Skeletal Muscle Fatigue

Comprehensive Physiology, 2012
Abstract Skeletal muscle fatigue is defined as the fall of force or power in response to contractile activity. Both the mechanisms of fatigue and the modes used to elicit it vary tremendously. Conceptual and technological advances allow the examination of fatigue from the level of the single molecule to the intact

Neurobiology of muscle fatigue

Journal of Applied Physiology, 1992
Muscle fatigue encompasses a class of acute effects that impair motor performance. The mechanisms that can produce fatigue involve all elements of the motor system, from a failure of the formulation of the descending drive provided by suprasegmental centers to a reduction in the activity of the contractile proteins. We propose four themes that provide

Skeletal Muscle Fatigue

Physical Therapy Reviews, 2002
Skeletal muscle fatigue is a complex problem which deserves attention from physiotherapists and other clinical practitioners. This article will discuss the findings of recent literature to explore some of the main mechanisms thought to underlie fatigue in skeletal muscles. These mechanisms may be peripheral in origin, occurring within the muscle fibres

Respiratory Muscle Fatigue

1995
Ventilatory failure may accompany a variety of pulmonary and neuromuscular diseases. There has been much controversy about whether this failure is due to respiratory muscle fatigue at peripheral sites or a failure of drive at sites within the central nervous system. The chapter reviews this topic.

Indices of muscle fatigue

Journal of Electromyography and Kinesiology, 1991
Myoelectric signal variables and mechanical variables are known to change during sustained voluntary or electrically elicited contractions. These phenomena reflect changes in the properties of the muscle fiber and its membrane. Such changes are generally called "fatigue." Muscle fiber conduction velocity and myoelectric signal spectral parameters (mean
