Reflex responses of single motor units have been used for the study spinal circuitries but methods employed are invasive and limited to assessment a relatively small number units. We propose new approach investigate reflexes on individual based high-density surface electromyography (HDsEMG) decomposition. The decomposition HDsEMG has previously validated in voluntary isometric contractions never during reflex activities. use studies at unit level, constant force contractions, with excitatory...
The electrical activity of muscles can interfere with the electroencephalogram (EEG) signal considering anatomical locations facial or masticatory surrounding skull. In this study, we evaluated possible interference resting temporalis muscle on EEG under conventional recording conditions. 9 healthy adults from 19 scalp and single motor unit (SMU) anterior were recorded in three relaxed conditions; eyes open, closed, jaw dropped. was spike triggered averaged (STA) using action potentials SMUs...
Reflex responses of tibialis anterior motor units to stretch stimuli were investigated in human subjects. Three types applied (tap-like, ramp-and-hold, and half-sine stretch). Stimulus-induced single analyzed using the classical technique, which involved building average surface electromyogram (SEMG) peristimulus time histograms (PSTH) from discharge times frequencygrams (PSF) instantaneous rates units. With use SEMG PSTH, tap-like stimulus induced five separate reflex responses, on average....
[Purpose] Whole-body vibration (WBV) can induce reflex responses in muscles. A number of studies have reported that the physiological mechanisms underlying this type activity be explained by reference to a stretch-induced reflex. Thus, primary objective study was test whether WBV-induced muscular (WBV-IMR) as [Subjects and Methods] The present assessed 20 healthy males using surface electrodes placed on their right soleus muscle. latency tendon (T-reflex) compared with WBV-IMR. In addition,...
High rate stimulations of the neuromuscular system, such as continuous whole body vibration, tonic vibration reflex and high frequency electrical stimulation, are used in physiological research with an increasing interest. In these studies, neuronal circuitries underlying responses remain unclear due to problem determining exact latencies. We present a novel "cumulated average method" determine latency during stimulation nervous system which was proven be significantly more accurate than...
To determine vibration parameters affecting the amplitude of reflex activity soleus muscle during low-amplitude whole-body (WBV).This study was conducted on 19 participants. Vibration frequencies 25, 30, 35, 40, 45, and 50 Hz were used. Surface electromyography, collision force between platform participant's heel measured using a sensor, acceleration an accelerometer fixed to simultaneously recorded.The main independent predictor electromyographic amplitude.The essential parameter is force.
Double discharges (doublets) were recorded from human soleus, where they have never been found before. The data analyzed in this study collected 12 healthy volunteers. subjects recruited for other studies, concerning: (1) estimation of motoneurons’ afterhyperpolarization duration and (2) analysis motor unit responses to nerve stimulation, not trained voluntarily evoke doublets. majority doublet intervals fell into the commonly accepted range 2–20 ms. However, two soleus motoneurons one...
Electromagnetic fields have various effects on intracellular calcium levels, free oxygen radicals and enzymes. The platelet activation pathway involves an increase in levels protein kinase C activation; play a mediating role this pathway. This study investigated whether 1 mT 6 mT, 50 Hz magnetic had any aggregation.Blood from healthy volunteers was anticoagulated with either citrate or heparin. Each sample divided half assigned to exposure control groups. Platelet rich plasma samples the...
Platelets are subjected to extremely low frequency electromagnetic fields during standard aggregometry measurements owing the use of a magnetic stir bar in instrument. This study evaluates effects this field exposure on platelet aggregation by comparing results obtained modified aggregometer. Blood samples from healthy volunteers were anticoagulated using citrate or heparin. Platelet-rich plasma (PRP) prepared. A mechanical stirring device was attached aggregometer instead system. The PRP...
We examined the reflex response of human masseter muscle to electrical stimulation lip using both single motor unit and surface electromyogram based methods. Using classical analysis methods, mild stimuli generated two distinct short-lasting inhibitions. This pattern may reflect development combinations short- long-latency inhibitory postsynaptic potentials as a result mildly painful stimulation. However, this appearing in methods have developed consequence earlier responses not be genuine....
