The Effect of Color on the Use of Electronic Body Protectors in Taekwondo Matches
2016
This study investigated the relationship between the color protector and success in taekwondo combats in the qualification championships, when electronic body protectors were used. Moreover, it analyzed the confounding effect of a participant being a top-ranked athlete in the 2012 London Olympic Games, in a sample of 462 matches. Results from the entire sample showed a non-significant relationship between the combat outcome and the winner’s color electronic protector. At the level of the tournament, the results showed a significant relationship between wearing a red electronic protector and winning the combat in the Asian and the European qualification tournaments. For gender and weight ca…
[Clinical and radiological evolution of a group of untreated acoustic neuromas].
2013
Abstract Introduction The acoustic neuroma is a benign tumour that originates in the vestibular branch of the eighth cranial nerve. The main treatment is surgery, but many authors suggest that with elderly patients or in small neuromas we can opt for watchful waiting. Methods This was a retrospective study from 2007 to 2013 that included 27 patients diagnosed of acoustic neuroma that had not been treated due to the size of the tumour, age and comorbidities, or by patient choice. We evaluated overall condition, hearing thresholds, degree of canal paresis and central disorders. Results After 6 years of follow up, clinical manifestations of 18 patients remained unchanged, 5 patients underwent …
FUNCTIONAL EFFECT OF SHORT-TERM IMMOBILIZATION: KINEMATIC CHANGES AND RECOVERY ON REACHING-TO-GRASP
2012
Abstract Although previous investigations agree in showing significant cortical modifications related to short-term limb immobilization, little is known about the functional changes induced by non-use. To address this issue, we studied the kinematic effect of 10 h of hand immobilization. In order to prevent any movement, right handed healthy participants wore on their dominant hand a soft bandage. They were requested to perform the same reaching-to-grasping task immediately after immobilization, 1 day before (baseline 1) and in other two following days without non-use (baseline 2 and baseline 3). While no differences were found among baseline conditions, an increase of the total duration of…
Comparison of electromyographic pattern of sensory experts and untrained subjects during chewing of Mahon cheese
2002
Use of electromyography (EMG) to monitor mastication is a relatively new concept in assessing food physical and sensory properties. Although expert assessment of cheese characteristics is widely used, the effect of training in sensory analysis on mastication patterns, as assessed using EMG is not well known. Nine samples of the same Mahon cheese (60 days ripening) were given to 24 subjects (8 experts, 16 untrained) and EMG recorded for each chewing sequence. Three samples were tested in a single session by each subject, and three sessions carried out on different days. EMG was recorded from four masticatory muscles for each subject. From EMG records the following was extracted: number of ch…
The time course of temporal discrimination: An ERP study
2009
Objective: The question of how temporal information is processed by the brain is still a matter of debate. This study aimed to elucidate the brain electrical activity associated with a visual temporal discrimination task. Methods: For this purpose, 44 participants were required to compare pairs of sequentially presented time intervals: a fixed standard interval (1000 ms), and an equal-to-standard, longer (1200 ms) or shorter (800 ms) comparison interval. Behavioural data and event-related potentials (ERPs) were analyzed. Results: Long intervals were more rapidly identified than short intervals. The amplitude of the contingent negative variation (CNV) found at frontocentral sites before the …
Influence of somatosensory input on motor function in patients with chronic stroke.
2004
In healthy volunteers, reduction of somatosensory input from one hand leads to rapid performance improvements in the other hand. Thus, it is possible that reduction of somatosensory input from the healthy hand can influence motor function in the paretic hand of chronic stroke patients with unilateral hand weakness. To test this hypothesis, we had 13 chronic stroke patients perform motor tasks with the paretic hand and arm during cutaneous anesthesia of the healthy hand and healthy foot in separate sessions. Performance of a finger tapping task, but not a wrist flexion task, improved significantly with anesthesia of the hand, but not the foot. This effect progressed with the duration of anes…
Inter- and intra-individual variability of paired-pulse curves with transcranial magnetic stimulation (TMS).
2002
Objectives: Previous studies have evaluated the variability of motor thresholds (MTs) and amplitude of motor-evoked potentials (MEPs) to transcranial magnetic stimulation (TMS) within and across individuals. Here we evaluate the reproducibility and inter-hemispheric variability of measures of cortical excitability using the 'conventional' paired-pulse (PP) TMS technique. Methods: We studied PP curves of the left and right hemisphere in 10 healthy subjects on two separate days 2 weeks apart. The inter-stimulus intervals studied were 1, 3, 6, 8, 10 and 12 ms with the conditioning stimulus being 80% of the resting MT, and a single test stimulus producing MEPs of approximately 0.8 mV peak-to-pe…
Sudden Sensorineural Hearing Loss: Results of intratympanic steroids as salvage treatment
2012
Objective: The aim of the present study was to verify the efficacy and the safety of intratympanic dexamethasone to treat sudden sensorineural hearing loss as salvage therapy. Materials and methods: A prospective study was conducted on patients affected by idiopathic sudden hearing loss who were treated before with some systemic therapy, but without recovery of the hearing The patients able to undergo the study, but who refused salvage treatment were considered as control group. A solution of Dexamethasone 4 mg/ml was then injected through the posterior–inferior quadrant filling completely the middle ear. The follow-up in the following 6 months included an audiogram every month. Results: Th…
Treatment of sudden sensorineural hearing loss with transtympanic injection of steroids as single therapy: a randomized clinical study.
2011
The aim of this study was to verify the efficacy and the safety of transtympanic dexamethasone to treat sudden sensorineural hearing loss as first and single drug method. Considering ethical implication of performing a mininvasive procedure on middle ear, we matched such proposed treatment with systemic prednisone administration that represents the widest adopted protocol. Randomized prospective study was conducted. The inclusion criterion was a sudden sensorineural hearing loss of at least 30 dB across three contiguous frequencies over a period of 24 h. Group A received transtympanic steroid injections; Group B received oral administration of steroids. 25 patients were treated with transty…
Intratympanic Dexamethasone/Hyaluronic Acid Mix as an Adjunct to Intravenous Steroid and Vasoactive Treatment in Patients With Severe Idiopathic Sudd…
2011
To evaluate differences in effectiveness (hearing recovery rates) between idiopathic sudden sensorineural hearing loss (ISSNHL) patients treated with intravenous therapy alone and patients treated with a combination of intravenous and intratympanic therapy.Retrospective case review.Tertiary referral hospital center.Ninety-four patients with moderate ISSNHL treated with an intravenous steroid and vasoactive regimen (duration of therapy, 9 ± 2.76 d) and 76 patients with severe ISSNHL treated with a combination regimen of intravenous and intratympanic therapy (duration of therapy, 10 ± 2.71 d) were reviewed. In the latter patients' group, a series of 3 intratympanic injections of a dexamethaso…
