A Wireless Surface Electromyography (WSEMG) System
Surface Electromyography (SEMG) systems are utilized throughout the medical industry to study abnormal electrical activity of the human muscle. Historically, SEMG systems employ surface (skin) mounted sensors that transmit electrical muscle data to a computer base via an umbilical cord. A typical …

Development of a Modular Electromyography System
The design of current electromyography (EMG) systems focuses on specific applications. One design focuses on the use of bipolar electrodes to monitor a single muscle group. Several of these electrodes can then be used to monitor different muscles on the body simultaneously. Another design places …

Reliability of electromyography detection systems for the pelvic floor muscles
… investigate the reliability of three different electromyography (EMG) detection systems commonly used to acquire EMG data from the pelvic floor muscles (PFM) at rest, during maximum voluntary contractions (MVCs) and during a coughing task. Twelve nulliparous women between the ages of 24 and 40 …

A comparison of fast and slow contraction speeds using electromyography
The purpose of this study was to determine if differences in EMG activity existed between fast and slow contraction speeds during isolated, one-armed biceps curls to muscle failure. Participants performed one set of biceps curls to muscular failure on two separate occasions at different contraction …

Muscle guarding during Kt-1000 testing as measured by electromyography
Twelve anterior cruciate deficient ACL-D participants volunteered for the study to compare muscular activity before and during two different protocols of KT-1000 knee arthrometer testing (KT-1000). Muscular activity was measured by the amount of electrical activity in specific muscles which cross …

Evaluation of Global Muscle Innervation Using Multi-Channel Surface Electromyography
Introduction: Advances in multi-channel surface electromyography (sEMG) have enabled the non-invasive assessment of neuromuscular function at the muscle and motor unit level. Specifically, sEMG has been used to assess the location of innervation zones (IZs) and the quantity of functioning …

Surface electromyography of facilitated versus free arm activation after stroke
The aim of this study is to determine if the amount of volitional muscle activation in a stroke affected arm is altered by facilitation. An experiment was designed in which surface EMG was recorded from the biceps brachii and triceps brachii of seven acute stroke patients, during three types of …
