Motor and cognitive growth following a Football Training Program
2015
Football may be a physical and sport activities able to improve motor and cognitive growth in children. Therefore the aim of this study was to assess whether a Football Training Program taken over 6 months would improve motor and cognitive performances in children. Motor skills concerned coordinative skills, running and explosive legs strength. Cognitive abilities involved visual discrimination times and visual selective attention times.Forty-six children with chronological age of ~9.10 years, were divided into two groups: Group 1 (n=24) attended a Football Exercise Program and Group 2 (n=22) was composed of sedentary children.Their abilities were measured by a battery of tests including mo…
Study on the Influence of Beginner Gymnasts’ Neuromuscular Control Using Computer-assisted Move 1 Du Portable Appliance
2014
Abstract The study aims at evaluating, training and improving upper limb neuromuscular control in preschool gymnasts as well as at highlighting the benefits of using computerized resources (MOVE 1 DU portable appliance) in training this control type. The research method chosen for this project consists in conducting an experiment on a group of 10 subjects aged 6-7 years. The key purpose of this study is to offer a more accurate and realistic view on the potential use of computer resources in training the neuromuscular control of the upper limb.
Functional brain imaging: a window into the visuo-vestibular systems
2007
Advances have been made in identifying how areas involved in processing vestibular, ocular motor, and visual information are represented in the human cortex as well as the cortical interaction between these systems in healthy subjects.While we know how some vestibular and ocular motor disorders modify visuo-vestibular interaction by changing the 'normal' cortical activation-deactivation patterns, it is still early days in functional magnetic resonance imaging studies of patients with specific disorders. Findings from current brain imaging studies of several vestibular, ocular motor, and cerebellar disorders are presented.The promise of more insights into the complex neuronal networks of the…
Acute heavy-resistance exercise–induced pain and neuromuscular fatigue in elderly women with fibromyalgia and in healthy controls: Effects of strengt…
2006
Objective To examine heavy-resistance exercise–induced acute neuromuscular fatigue, blood lactate concentration, and muscle pain in elderly women with fibromyalgia (FM) and in healthy controls before and after a period of strength training. Methods Thirteen elderly women with FM (mean ± SD age 60 ± 2 years) and 10 healthy women (mean ± SD age 64 ± 3 years) performed a heavy-resistance fatiguing protocol (5 sets of leg presses with 10 repetitions maximum) before and after a 21-week strength training period. Maximal isometric force and electromyography (EMG) activity of leg extensors and blood lactate concentration were measured during the loading. Pain was assessed by visual analog scale. Re…
Physical Fitness in Postmenopausal Women with Fibromyalgia
2007
The purpose of this study was to compare physical fitness and health-related quality-of-life between twenty-three postmenopausal women with fibromyalgia (age 58 +/- 3 years) and eleven healthy women (58 +/- 5 years). Aerobic fitness and isometric force of different muscle groups were measured. Functional performance was assessed by walking and stair-climbing times. Symptoms were assessed by visual analog scale and quality-of-life by RAND-36 questionnaire. Women with fibromyalgia had significantly lower isometric force in bilateral leg extensors (1285 vs. 1898 N), unilateral knee extensors (414 vs. 502 N) and flexors (197 vs. 235 N) than healthy women, but no differences were observed in for…
ERPs to pitch changes: a result of reduced responses to standard tones in rabbits.
1996
EVENT-RELATED potentials (ERPs) were recorded in rabbits when pitch deviant tones occurred in a series of standard tones (oddball situation). In control recordings, the deviant tones were presented without the standard tones (deviant-alone situation). In the oddball situation, significant difference ERPs (deviant ERPs - standard ERPs) could be found in the hippocampal and cerebellar recordings but not in the visual cortex. All the ERPs to the deviant stimuli observed in the oddball situation were also present in the deviant-alone situation. The difference ERPs were therefore based on reduced responses to the standards. The results are discussed in the context of a mismatch negativity (MMN) …
A Randomised-Controlled Clinical Study Examining the Effect of High-Intensity Laser Therapy (HILT) on the Management of Painful Calcaneal Spur with P…
2021
Calcaneal spur and plantar fasciitis are the most common causes of plantar heel pain. There are many effective physical modalities for treating this musculoskeletal disorder. So far, the are no clear recommendations confirming the clinical utility of high-intensity laser therapy (HILT) in the management of painful calcaneal spur with plantar fasciitis. This study aimed to evaluate the effectiveness of HILT in pain management in patients with calcaneal spur and plantar fasciitis. A group of 65 patients was assessed for eligibility based on the CONSORT guidelines. This study was prospectively registered in the Australian New Zealand Clinical Trial Registry platform (registration number ACTRN1…
Psychophysical and electrofunctional contrast sensitivity in cataractous patients treated with bendazac-lysine salt
1990
The clinical progression of the cataract may be influenced by drugs which reduce the denaturation of lens proteins. One of the most promising drugs is the bendazac-lysine salt. The drug was used in a double-blind study of a group of patients with initial cortical cataract in order to evaluate the changes in visual acuity and contrast sensitivity by means of a psychophysical and an electrophysiological method. After 6 months of treatment with bendazac the mean values of visual acuity showed a statistically significant increase in respect to baseline values, as well as an improvement of the threshold of contrast for most spatial frequencies. In the eyes treated with placebo there was no stati…
Multidimensional Optical Sensing and Imaging Systems (MOSIS): From Macro to Micro Scales
2017
Multidimensional optical imaging systems for information processing and visualization technologies have numerous applications in fields such as manufacturing, medical sciences, entertainment, robotics, surveillance, and defense. Among different three-dimensional (3-D) imaging methods, integral imaging is a promising multiperspective sensing and display technique. Compared with other 3-D imaging techniques, integral imaging can capture a scene using an incoherent light source and generate real 3-D images for observation without any special viewing devices. This review paper describes passive multidimensional imaging systems combined with different integral imaging configurations. One example…
Assessment of environmental AMD risk factors in a population of patients suffering from stroke and myocardial infarction
2010
International audience; Purpose: Stroke and myocardial infarction are common diseases occurring in patients suffering from Age Macular Degeneration (AMD). We assessed the rate of AMD and AMD risk factors in patients suffering from recent stroke or myocardial infarction. Methods: Patients suffering from a recent stroke or myocardial infarction (less than 1 month) benefited from a thorough ophthalmic examination with the following measurements and evaluations: visual acuity, intraocular pressure, fundus photography, Raman spectroscopy and macular OCT. In the same time a food questionnaire was dispensed. Finally, blood samples to measure fatty acids and lutein were performed. Results: 74 patie…
