Introduction: The rapid development of wireless telecommunication technologies over the past decades, has led to significant changes in the exposure of the general public to electromagnetic fields. Nowadays, people are continuously exposed to different sources of electromagnetic fields such as mobile phones, mobile base stations, cordless phones, Wi-Fi routers, and power lines. Therefore, th...

Objective: Carpal tunnel syndrome (CTS) is the most common peripheral neuropathy affecting upper limbs. Various treatment methods exist for this disease, but only a few reports have compared effects of various treatments using objective indicators. This study analyzed changes in electrophysiological parameters after carpal release.Methods: In patients planning to undergo surgical CTS, studies, ...

The contribution of force-sensitive muscular afferents to prolonged flexion withdrawal reflexes, or flexor spasms, following human spinal cord injury (SCI) was investigated. In three separate experimental conditions, flexion reflexes were triggered in subjects with SCI using trains of electrocutaneous stimuli delivered at the foot and lower leg and compared to reflexes elicited via intramuscula...

background: h-reflex is a valuable electrophysiological technique for assessing nerve conduction through entire length of afferent and efferent pathways, especially nerve roots and proximal segments of peripheral nerves. the aim of this study was to investigate the relation between normal values of flexor carpi radialis (fcr) h-reflex latency, upper limb length and age in normal subjects, and t...

31 Plantar flexor series elasticity can be used to dissociate muscle-fascicle and 32 muscle-tendon behaviour and, therefore, afferent feedback during human walking. We 33 used electromyography (EMG) and high speed ultrasonography concomitantly to 34 monitor muscle activity and muscle fascicle behaviour in nineteen healthy volunteers 35 as they walked across a platform. On random trials, the pla...

Introduction: The study aimed to investigate the onset time and the electromyographic activity level of the selected lower limbs muscles in active and inactive aged women. Methods: in this case-control study, 28 aged women with a mean age of 61.07±0.88 were selected in two groups of inactive (15 people) and active (13 people). The electrical activity of the selected muscles of the lower l...

Plantar flexor series elasticity can be used to dissociate muscle-fascicle and muscle-tendon behavior and thus afferent feedback during human walking. We used electromyography (EMG) and high-speed ultrasonography concomitantly to monitor muscle activity and muscle fascicle behavior in 19 healthy volunteers as they walked across a platform. On random trials, the platform was dropped (8 cm, 0.9 g...

This paper presents data describing the latency of the onset of pathological gambling (PG) in a large sample (N = 180) of men and women seeking treatment at the Rhode Island Gambling Treatment Program (RIGTP). The current study replicates the findings of Breen and Zimmerman (2002), and confirms that involvement with computerized gambling devices, such as video slots and video poker, is associat...

Stimulus response latency is the delay between stimulus onset and the evoked modulation in neural activity. A common technique to estimate latencies involves binning the spike arrival times to form a peri-stimulus histogram. This histogram is smoothed using a fixed bandwidth. The estimated latency is the first time following stimulus onset in which the smoothed histogram exceeds the midpoint be...

Transcallosal inhibition (TCI), assessed using transcranial magnetic stimulation, can provide insight into the neurophysiology of aging and of neurological disorders such as stroke. However, the reliability of TCI using the ipsilateral silent period (iSP) has not been formally assessed, despite its use in longitudinal studies. This study aimed to determine the reliability of iSP onset latency, ...
