The Effect of Lower Extremity Muscle Fatigue on Dynamic Postural Control Analyzed by Electromyography
Purpose: Postural control preserves organs and body parts in a proper biomechanical stance which exists in two forms: static and dynamic. Fatigue is one of the factors that affects postural control. This study aimed to compare the electromyography (EMG) activity of the lower extremity muscles before and after fatigue. Methods: This study was descriptive correlational and based on the research ...
متن کاملMuscle conduction velocity, surface electromyography variables, and echo intensity during concentric and eccentric fatigue.
INTRODUCTION Concentric (CON) and eccentric (ECC) contractions may involve different mechanisms related to changes in sarcolemma status and the consequent alteration of action potential transmission along muscle fibers. METHODS Muscle conduction velocity (CV), surface electromyography signal (sEMG), muscle quality, and blood lactate concentrations were analyzed during CON and ECC actions. R...
متن کاملEstimation of muscle fatigue using surface electromyography and near-infrared spectroscopy.
This study looks at various parameters, derived from surface electromyography (sEMG) and Near Infrared Spectroscopy (NIRS) and their relationship in muscle fatigue during a static elbow flexion until exhaustion as well as during a semidynamic exercise.We found a linear increasing trend for a corrected amplitude parameter and a linear decreasing slope for the frequency content of the sEMG signal...
متن کاملShoulder Muscle Fatigue During Repetitive Tasks as Measured by Electromyography and Near-Infrared Spectroscopy
OBJECTIVE The objective of this study was to quantify shoulder muscle fatigue during repetitive exertions similar to motions found in automobile assembly tasks. BACKGROUND Shoulder musculoskeletal disorders (MSDs) are a common and costly problem in automotive manufacturing. METHOD Ten subjects participated in the study. There were three independent variables: shoulder angle, frequency, and ...
متن کاملFatigue Assessment Scales: A comprehensive literature review
Background & Aims of the Study: Fatigue is one of the most important issues relating with safety and other aspects of human life. To understand fatigue and its relative factors and causes, there is a need to useful instruments, such as self-reported scales. The purpose of this study is to identify and present useful self-reported scales to measure fatigue. Materials & Methods: Data were extrac...
