Background: Electromyography (EMG) signal processing and Muscle Onset Latency (MOL) are widely used in rehabilitation sciences and nerve conduction studies. The majority of existing software packages provided for estimating MOL via analyzing EMG signal are computerized, desktop based and not portable; therefore, experiments and signal analyzes using them should be completed locally. Moreover, a...

objective:  unaccustomed and intense eccentric exercise is a common cause of delayed-onset muscle soreness (doms). there are multiple remedies for the treatment of doms, but its clinical and laboratory pieces of evidence are scarce. currently, the treatments proposed for doms are numerous and include pharmaceuticals, herbal remedies, stretching, massage, nutritional supplements, and other alter...

background and aim: this study investigated whether objective temporal processing paradigms including voice-onset-time, speech-in-noise, and amplitude modulated-broad-band noise (am-bbn) are sensitive to disrupted temporal processing in elderly listeners with normal hearing (age-related-temporal processing deficit). methods: we evaluated 15 adults aged 64–80 years using behavioural measures of ...

inflammation and pain induced by delayed onset muscle soreness (doms) can be induced by eccentric exercise or an unaccustomed activity. the condition can causes problems in exercising and for athletes. the purpose of this study was to assess the effect of 150mg curcumin supplementation immediately after intensive eccentric exercise. evaluations were made for total antioxidant capacity (tac), mu...

Acetylcholine or carbachol were applied iontophoretically to longitudinal smooth muscle from taenia or ileum of guinea pigs by means of a micropipette, while the membrane potential was recorded intracellularly by microelectrode. Contraction of the muscle was prevented by hyperpolarizing the membrane with inward current in a double-sucrose gap apparatus or, occasionally, by the use of a bathing ...

background: n-acetylcysteine (nac) has been indicated against experimental seizures, but with relatively inconclusive results. this study was undertaken to evaluate whether nac exerts a dose-dependent anticonvulsant effect and to determine nac safe therapeutic dose range and its muscle-relaxant activity in both acute and chronic uses. methods: following intraperitoneal (i.p.) administration of ...

Unpredictable forces which perturb balance are frequently applied to the body through interaction between the upper limb and the environment. Lower limb muscles respond rapidly to these postural disturbances in a highly specific manner. We have shown that the muscle activation patterns of lower limb muscles are organized in a direction specific manner which changes with lower limb stability. An...

The central nervous system takes advantage of prior knowledge about potential upcoming perturbations for modulating postural reflexes. There are two distinct aspects of prior knowledge: spatial and temporal. This study investigated how each of spatial and temporal prior knowledge contributes to the shortening of muscle response latency. Eleven participants walked on a split-belt treadmill and p...

INTRODUCTION High intensity cutaneous stimulus transiently suppresses tonic voluntary muscle activity resulting in cutaneous silent period (CSP). AIM The aim of our study was to evaluate the normal values of an onset latency L1, a late latency L2 and a duration of CSP after stimulating sensory fibres of the median nerve. MATERIAL AND METHODS This prospective study was performed at the Neuro...

Muscle reflexes, evoked by opposing a sudden joint displacement, may be modulated by several factors associated with the features of the mechanical perturbation. We investigated the variations of muscle reflex response in relation to the predictability of load magnitude during a reactive grasping task. Subjects were instructed to flex the fingers 2-5 very quickly after a stretching was exerted ...
