Background While many studies have been performed on the effects of exercise on Adolescent Idiopathic Scoliosis (AIS) little research has been done into the underlying muscle physiology. Studies have suggested a fibre type imbalance, however, the implications of this difference as reflected through fatiguability have not been studied. The slope of the median frequency of the surface electromyog...

UNLABELLED Total laryngectomy is a surgical procedure that can change swallowing biomechanics, including muscle activity of the masseter; this muscle stabilizes the mandible. AIM To characterize the electrical activity of the masseter muscle during swallowing after total laryngectomy. Series study. MATERIAL AND METHODS An electromyographic evaluation of swallowing was carried out; three dif...

BACKGROUND This study examines the clinical and electromyographic results of latissimus dorsi transfer (LDT) using a combined open and arthroscopic technique for the treatment of symptomatic irreparable posterosuperior rotator cuff tears. METHODS Between 2006 and 2009, LDT was performed in 14 patients (mean age 59 years) with massive and symptomatic irreparable posterosuperior rotator cuff te...

One of the problems that most concerns the elderly population is the falling, which can be caused by muscle fatigue. The objective of this study was to compare median electromyographic frequency values for the vastus lateralis muscle and the lateral portion of the gastrocnemius muscle (as parameters of electromyographic fatigue) in elderly people with and without a history of falls. A total of ...

Electromyographic signals contaminated with noise during the acquisition process affect results of follow-up applications such as disease diagnosis, motion recognition, gesture and human–computer interaction. This paper proposes a denoising technique based on variational mode decomposition (VMD) for both surface electromyography (sEMG) intramuscular (iEMG). sEMG iEMG obtained from 5 healthy sub...

The article analyzes and calculates informative parameters of surface electromyographic signals (sEMS), which can be used to control biotechnical systems, as well diagnose the state musculoskeletal system. analysis in time frequency-time domains signal are considered. A program has been developed for calculating indicators indicated areas. is implemented LabVIEW environment. To analyze sEMG dom...

Pain assessment is very important in establishing the efficacy of analgesics and therapies, but because pain is a subjective experience, using methods that represent pain objectively is necessary. A number of biopotentials have been employed in studies of the objective assessment of pain. However, few investigations have considered the peripheral nervous system response to electrical stimulatio...

Intramuscular electromyographic (EMG) signals are detected with needles or wires inserted into muscles. With respect to non-invasive techniques, intramuscular electromyography has high selectivity for individual motor unit action potentials and is thus used to measure motor unit activity. Decomposition of intramuscular signals into individual motor unit action potentials consists in detection a...

OBJECTIVES/HYPOTHESIS Thermal injury to the recurrent laryngeal nerve (RLN) may not be visually apparent and may go unrecognized intraoperatively. This study aimed to investigate the heat thermal tolerance of RLN and evaluate the electrophysiologic correlates of electromyographic (EMG) signal change during an acute RLN heat damage. STUDY DESIGN Prospective porcine model with continuous intrao...
