Sudden cardiac death (SCD) is a critical event occurring within an hour of sudden cardiac arrest (SCA). SCA often arises from disruptions in cardiac electrical signals, leading to fatality by hindering blood circulation. SCD, a significant contributor to cardiovascular-related deaths, impacts millions people globally. Most studies in the literature...

Muscle fatigue is described by the decline in muscle maximum force during contraction. The fatigue occurs in the nervous or muscle fibre cells. The nerves produce a high-frequency signal to gain the maximum contraction, but it cannot sustain the high frequency signal for a long time, and that leads to a decline in muscle force. The surface Electrom...

The main goal of this research work is to study and evaluate the muscles force and fatigue of Gastrocnemius Medialis (GMS), Gluteus Maximus (GM), and Gastrocnemius Lateralis (GL) during running for 400-meters based on surface Electromyography (sEMG) signals. The sEMG signals of the selected muscles from the right leg have been collected by using bi...

Incorrect running may lead to discomfort and injuries, where each day around the world, the numbers of runners are increasing. The goal of this research work is to evaluate and study the lower limb muscles fatigue during running for 400-meters with two types of running strategies based on the Electromyography (EMG) signals. The EMG signals are coll...

The aim of this research work is to assess the muscles fatigue of the male runner during 400 meters (m) running with three types of running strategies. The Electromyography (EMG) signals from the Rectus Femoris (RF), Biceps Femoris (BF), Gluteus Maximus (GM), Gastrocnemius Lateralis (GL), and Gastrocnemius Medialis (GMS) were collected by using bip...

Arrhythmia, a common form of heart disease, can be detected from an electrocardiogram (ECG) signal. This research work presents a comparative study between five feature extraction methods applied separately on two window sizes for detecting three ECG pulse types, namely normal and two arrhythmia variations. The library support vector machine (LIBSV...

The main aim of this paper is to present a controlling method for the movements of the wheelchair in a different direction: forward, backward, right side, left side, and stop condition. This method depended on the electrical signals of the muscles that are collected from the masseter and buccinators muscles by using the Electromyogram (EMG). After...

There are many elderly people who lack the control of movement of their upper or lower limbs. There are also many people affected and who are paralyzed. For this reason, the wheelchair is very important for these people to help them daily. The aim of this work is to present a control method of wheelchair movement in five directions: (forward, rever...

The electric wheelchair is becoming increasingly critical in assistive technological and rehabilitation devices. The wheelchair is usually controlled by the joystick. Nevertheless, it's not always well suited for impaired people that lack control of the upper or lower-limbs. Latest advances of Electric Power Wheelchair (EPWs) based on electromyogra...

The wheelchair is very important for the elderly people who are lacking the ability of controlling their upper or lower limbs to help them moving from place to another without any help from the other's persons. The aim of this research work is to present a new controlling method on the wheelchair movements depended on the EMG signals that collected...
