OBJECTIVE To establish a correlation between the modified Ashworth scale (MAS) and amplitude and latency of T-reflex and to demonstrate inter-rater and intra-rater reliability of the T-reflex of the biceps muscle for assessing spasticity after stroke. METHOD A total of 21 patients with hemiplegia and spasticity after ischemic stroke were enrolled for this study. The spasticity of biceps muscl...
[Purpose] In this study, we aimed to verify the trunk motion characteristics of anticipatory postural adjustments (APAs) made by post-stroke hemiplegic patients at gait initiation. [Participants and Methods] The participants were 10 elderly controls 30 stroke patients. Measurements using a center gravity measurement instrument, surface electromyograph, an accelerometer. Accelerometers attached ...
BACKGROUND This study investigated the effect of supplementation with fish oil rich in eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) on the M-wave latency of biceps brachii and muscle damage after a single session of maximal elbow flexor eccentric contractions (ECC). METHODS Twenty-one men were completed the randomized, double-blind, placebo-controlled, and parallel-design study....
The aim of the present study was to investigate the sleep promoting effect of BR-16A, a polyherbal formulation along with GABAergic drugs. Pentobarbitone-induced hypnosis test was used as an animal model to explore its role in sleep. Pentobarbitone produces quick the sleep latency (onset) and prolongation of total sleep time (duration). Seep latency and total sleep time were used as parameters ...
It is well known that many stimulus parameters, such as sound location in the auditory system or contrast in the visual system, can modulate the timing of the first spike in sensory neurons. Could first-spike latency be a candidate neural code? Most studies measuring first-spike latency information assume that the brain has an independent reference for stimulus onset from which to extract laten...
Background & Aims: This study was performed to compare the effects of open and closed chain terminal knee extension exercises on onset latency of vastus medialis obliques (VMO) and vastus lateralis (VL), pain and function in subjects diagnosed with patellofemoral pain syndrome (PFPS). Methods: In a pretest and posttest 5-week intervention study, 26 subjects diagnosed with PFPS and 13 healthy su...
Neurons in the pontomedullary reticular formation (PMRF) give rise to the reticulospinal tract. The motor output of the PMRF was investigated using stimulus-triggered averaging of electromyography (EMG) and force recordings in two monkeys (M. fascicularis). EMG was recorded from 12 pairs of upper limb muscles, and forces were detected using two isometric force-sensitive handles. Of 150 stimulat...
A near loss of smell may result from conductive and/or neural olfactory disorders. However, an olfactory test to selectively detect neural disorders has not been established. We investigated whether onset latency of sensory response to intravenous odor injection can detect neural disorders in humans and mice. We showed that longer preoperative onset latency of odor recognition to intravenous od...
Abstract Background: Several studies have examined the reflex response of ankle musculature to sudden inversion in noninjured and injured subjects. To date, there have been no studies to determine the effect of versatile degrees & conditions of perturbation on the ankle musculature latency. The purpose of this study was to measure and determine whether there was a difference in ankle musculatu...
Abstract Objective To investigate the cutaneous silent period (CSP) by measuring its onset latency, duration and amount signal suppression in patients with motor neuron disease (MND) grouped according to intensity of upper involvement (UMN), test effect contralateral hand contraction. Methods Painful stimulation was applied at V finger, contraction recorded from abductor digiti minimi (ADM) mus...
