Harvesting biomechanical energy from daily human body motions provides a promising and sustainable power solution for wearable electronics, whose current supplies, i.e., batteries, have unsatisfactory capacity durability due to volume, shape, flexibility constraints. Electromagnetic generators (EMGs) are favorable transducers because of their high energy-conversion efficiency, low dependence on...

background: most dentists complain of musculoskeletal disorders which can be caused by prolonged static posture, lack of suitable rest and other physical and psychological problems. objective: we evaluated a chair with a new ergonomic design which incorporated forward leaning chest and arm supports. methods: the chair was evaluated in the laboratory during task simulation and emg analysis on 12...

Frequency analysis may have some advantages over back-averaging in the neurophysiological assessment of patients with suspected cortical myoclonus in whom myoclonic EMG bursts repeat rhythmically at high frequency. However, the clinical utility of EEG-EMG coherence and related EMG-EMG coherence is not established. Equally, there is an incomplete understanding of the physiology of the systems co...

background and purpose: disc herniation leading to radiculopathy is one of the important differential diagnosis of low back pain which needs specific medical care. radiculopathies can be initially diagnosed by history taking and physical examination. however role of other diagnostic methods like magnetic resonance imaging (mri) and electromyography (emg) in narrowing differential diagnosis is w...

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...

AbstractBackgroundentity. It is hypothesized to result from abnormal patellar tracking caused by altered motorcontrol. Deficit in neuromotor control of the core may be a remote contributing factor to thedevelopment of PFP. Application of reliable EMG measures would be helpful to handle thistheory. Therefore, the purpose of this study was to determine the test-retest reliability of thecore and v...
