Is karate effective in improving postural control?

2012

Background: Performing complex motor skills, such as the ones performed by karate athletes, requires a great sense of balance. Because the posturo-kinetic performance seems to be improved by sport practice, especially by sports involving a lot of posturokinetic activities, the aim of this review was to critically analyse the scientific literature in order to appraise whether any positive correlation between karate and improved postural control is scientifically supported. Material/Methods: The online search engines Scirus and Medline were used for generating the data. A comprehensive literature search was conducted based on the following keywords: “karate”, “postural control” and “body sway…

Der Effekt von Neostigmin an der motorischen Endplatte beim Intermediärsyndrom der Alkylphosphatvergiftung

1991

A patient with severe organophosphate intoxication received Neostigmine 1 mg IV during the intermediate syndrome. This dose resulted clinically and neurophysiologically in a marked deterioration of neuro-muscular transmission. This effect of neostigmine on the neuromuscular block during the intermediate syndrome (deterioration) differs from its effect on a similar pattern (improvement), which is seen in the delayed neuropathy following organophosphate exposure. The administration of therapeutic doses of cholinesterase inhibitors in patients with a reduced safety margin due to inhibition of endplate acetylcholinesterase may be dangerous.

Relationship between habitual physical activity and gross motor skills is multifaceted in 5- to 8-year-old children

2013

Adequate motor skills are essential for children participating in age-related physical activities, and gross motor skills may play an important role for maintaining sufficient level of physical activity (PA) during life course. The purpose of this study was to examine the relationship between gross motor skills and PA in children when PA was analyzed by both metabolic- and neuromuscular-based methods. Gross motor skills (KTK--Korperkoordinationstest fur Kinder and APM inventory--manipulative skill test) of 84 children aged 5-8 years (53 preschoolers, 28 girls; 31 primary schoolers, 18 girls) were measured, and accelerometer-derived PA was analyzed using in parallel metabolic counts and neur…

Posterior ‘Motion Preserving’ Procedures (Frykholm)

2019

Cervical radiculopathy from degenerative disease is a common problem with an incidence of 0.83–1.79 per 1000 person years. It can be caused by a cervical disc herniation, bony foraminal stenosis or spinal canal stenosis. Upon failure of conservative therapy or a significant motor deficit surgical treatment is indicated. A posterior cervical foraminotomy is one surgical option for the treatment of selected patients with lateral cervical disc herniations.

Fundamental movement skills and physical fitness as predictors of physical activity: A 6-year follow-up study

2015

The purpose of this study was to examine the extent to which fundamental movement skills and physical fitness scores assessed in early adolescence predict self-reported physical activity assessed 6 years later. The sample comprised 333 (200 girls, 133 boys; M age = 12.41) students. The effects of previous physical activity, sex, and body mass index (BMI) were controlled in the main analyses. Adolescents’ fundamental movement skills, physical fitness, self-report physical activity, and BMI were collected at baseline, and their self-report energy expenditure (metabolic equivalents: METs) and intensity of physical activity were collected using the International Physical Activity Questionnaire …

Mesh Plates for Scapula Fixation

2015

While scapula fractures are often treated nonoperatively, there are a number of displaced fractures in which surgical treatment can be considered. When necessary, open reduction and internal fixation with plates is the accepted method for stabilization. However, there are limited options of commercially available plates for fixation of the scapula. The authors describe 2 cases of scapula fracture and 1 scapula osteotomy that were managed with internal fixation using low-profile mesh plates. The mesh plate is a stainless steel lattice that can be molded and trimmed to create a plate that matches the unusual 3-dimensional anatomy of the scapula. It accepts 2.4/2.7 mm cortical and variable ang…

Meta-analysis of the efficacy of different training strategies in animal models of ischemic stroke.

2013

Background and Purpose— Although several studies have shown beneficial effects of training in animal stroke models, the most effective training strategy and the optimal time to initiate training have not been identified. The present meta-analysis was performed to compare the efficacy of different training strategies and to determine the optimal time window for training in animal stroke models. Methods— We searched the literature for studies analyzing the efficacy of training in animal models of ischemic stroke. Training was categorized into forced physical training, voluntary physical training, constraint-induced movement therapy, and skilled reaching training. Two reviewers independently …

The Temporal Development of Early and Late CNV in a Simple Discrimination Paradigm: the Effects of Motor Preparation and Average Reaction Time

1980

Publisher Summary This chapter discusses the temporal development of early and late contingent negative variation (CNV) in a simple discrimination paradigm. The CNV typically arises when a warning stimulus is paired with an imperative stimulus which, in turn, is followed by a motor reaction. If the interstimulus interval is less than approximately 2 sec the CNV begins immediately after the positive deflection (P300) following the warning stimulus. It may appear as a steadily rising negative potential shift that reaches its peak with the presentation of the imperative stimulus, or as sustained negativity throughout the rest of the foreperiod. If the interstimulus interval is extended beyond …

Slowed abduction saccades in bilateral internuclear ophthalmoplegia

1992

Horizontal eye movements were investigated in 65 patients with bilateral internuclear ophthalmoplegia utilizing direct current electro-oculography. Abduction saccades were slowed in 35 patients (53.8%), being hypermetric in 65.7% of them. Slowing of abduction saccades is attributed to impaired inhibition of the tonic resting activity of the antagonistic medial rectus muscle. Experimental data indicate that this slowing results from a lesion of an uncrossed connection between the pontine reticular formation and the oculomotor nucleus. The prevalence of hypermetric abduction saccades increased with increasing severity of adduction paresis on the opposite eye. This confirms the view that media…
