Brachialis muscle activity can be assessed with surface electromyography.
The brachialis muscle (BR) represents an important elbow flexor and its activity has so far mainly been measured with intramuscular electromyography (EMG). The aim of this study was to examine whether the activity of the BR can be assessed with surface EMG without interference from the biceps brachii (BB). With eight subjects we measured surface EMG of the arm flexor synergists, BR, BB, and bra...
متن کاملCan masticatory electromyography be normalised to submaximal bite force?
The combination of bite force and jaw muscle electromyography (EMG) provides an insight into the performance of the stomatognathic system, especially in relation to dynamic movement tasks. Literature has extensively investigated possible methods for normalising EMG data encapsulating many different approaches. However, bite force literature trends towards normalising EMG to a maximal voluntary ...
متن کاملCan Anal Sphincter Defects Be Identified by Palpation?
OBJECTIVES The aim of this study was to correlate clinical findings of anal sphincter defects and function with a sonographic diagnosis of significant sphincter defects. METHODS This is an observational cross-sectional study on women seen 6 to 10 weeks after primary repair of obstetric anal sphincter injuries (OASIs). All patients underwent a standardized interview including the St Mark incon...
متن کاملComparative Study of Diagnostic Significance of Urethral Sphincter Electromyography and External Anal Sphincter Electromyography in Patients with Multiple System Atrophy
Objectives: to evaluate the diagnostic value of external anal sphincter electromyography (EAS-EMG) and urethral sphincter electromyography (US-EMG) in patients with multiple system atrophy (MSA). Methods: 35 patients who were diagnosed as MSA were examined as treatment group, while 53 non-MSA patients were examined as control group, using EAS and US-EMG. Data was recorded and analyzed, includin...
متن کاملRelation between electromyography and anal manometry of the external anal sphincter.
Thirteen patients with faecal incontinence and 26 control subjects were studied to investigate whether a quantitative electromyographic (EMG) signal could be correlated to anal manometry. Three different electrodes were used--a concentric needle electrode, a disposable sponge electrode, and a hard anal plug electrode. The maximum amplitude of the EMG recording was used as a quantitative paramet...
