A novel method for automated EMG decomposition and MUAP classification
OBJECTIVE This paper proposes a novel method for the extraction and classification of individual motor unit action potentials (MUAPs) from intramuscular electromyographic signals. METHODOLOGY The proposed method automatically detects the number of template MUAP clusters and classifies them into normal, neuropathic or myopathic. It consists of three steps: (i) preprocessing of electromyogram (...
متن کاملA Hybrid Classifier for Characterizing Motor Unit Action Potentials in Diagnosing Neuromuscular Disorders
Background: The time and frequency features of motor unit action potentials (MUAPs) extracted from electromyographic (EMG) signal provide discriminative information for diagnosis and treatment of neuromuscular disorders. However, the results of conventional automatic diagnosis methods using MUAP features is not convincing yet.Objective: The main goal in designing a MUAP characterization system ...
متن کاملبررسی تأثیر فاصلهی بین آنتنها در فرستنده و گیرنده بر روی ظرفیت کانال MIMO
In this paper, the spatial MIMO channel modeling (SCM) is introduced and the required parameters for this modeling are studied. Then, the MIMO channel gains and capacity are analyzed. The transmitter and receiver antenna patterns are also analyzed. Next, we are focused on the effects of the transmitter and receiver antenna arrays separations, the arrays length, and the angles spread on the ante...
متن کاملComparison of electromyographic activity of shoulder muscles during two different pull-up test methods
Pull-up and modified pull-up tests are frequently used for shoulder muscles endurance evaluation by physical educators. Despite of using these tests, the difference of muscle activation pattern in pull-up and modified pull-up tests has not been documented clearly. However, the role of some important muscles such as anterior deltoid, posterior deltoid, trapezius and latissimus dorsi have no...
متن کاملThe effect of forward head posture on muscle activity during neck protraction and retraction
[Purpose] The present study was performed to investigate whether forward head posture (FHP) affects muscle activity. [Subjects and Methods] Twenty subjects attending Y university in Gyeongsangnam-do, Republic of Korea. They were divided into two groups according to craniovertebral angle: a control group (n=10) and a FHP group (n=10). Electromyography electrodes were attached to the upper fibers...
