Reliability and concurrent validity of the Movement Assessment Battery for Children were evaluated with a sample of 106 boys and girls, distributed into four age groups: 5-6 yr. (n = 20), 7-8 yr. (n = 20), 9-10 yr. (n = 46), and 11-12 yr. (n = 20). Test-retest reliability of the Movement Assessment Battery for Children, estimated using intraclass(More)
The purpose of this investigation was to determine differences between pre- and post-pubescent males and females in quadriceps (vastus medialis; VM) and hamstrings (medial hamstrings and biceps femoris; HAMS) muscular activation patterns via the root mean square of surface electromyography (SEMG) during self-initiated vertical jump landing. Fifty-eight(More)
Coincident timing by individuals who exhibit traumatic brain injury was measured under conditions of no knowledge of results (no KR; n = 12), KR on every trial (n = 14), summary KR (n = 13), and average KR (n = 12). Following acquisition trials, groups performed immediate and longer retention trials without KR. Absolute constant error and variable error,(More)
The purpose of this study was to investigate the effect of movement velocity (100 degrees, 200 degrees , 300 degrees s(-1), and 400 degrees s(-1)) and joint position (0 degrees - 15 degrees [L0], 25 degrees - 40 degees [L25], 55 degrees - 70 degrees [L55], and 75 degrees - 90 degrees [L75]) on peak torque (PT) parameters and surface electromyography (SEMG)(More)
The purpose of this study was to examine the effect of ankle position fixation on peak torque (PT) and electromyographic (EMG) activity of knee-joint muscles during isokinetic testing. Twelve female athletes performed isokinetic knee flexion and extension at 60 degrees and 180 degrees/s under two conditions: with the ankle fixed in a position of(More)
Epidemiological data show a higher prevalence of late-onset Alzheimer's disease (AD) in women. The estrogenic deficiency in the post-menopausal period is suspected to be the cause of the gender-related risk of the disease, but studies on the estrogenic therapy and occurrence of AD were not consistent and sometimes contradicting. The aim of this study is to(More)
Reliable, simple and safe criteria are needed for the early prediction of short-term outcome in patients with acute ischemic stroke. The aim of our study was to evaluate, in terms of their individual and combined power, the prognostic value of a few widely available clinical and instrumental variables obtained during the acute phase. The study involved 351(More)
Individuals with vision loss are at an increased risk of falls. Understanding what factors contribute to postural instability within this population is a necessary step towards the development of physiotherapeutic programs targeted at reduction of falls within this population. Forty-six age-matched participants were evaluated with the sensory organization(More)
The effect of movement velocity and fatigue on the reciprocal coactivation of the quadriceps and hamstrings was investigated through analysis of the root mean square (RMS) and the median frequency (MDF) of surface electromyography for the vastus medialis (VM), vastus lateralis (VL), medial hamstrings (MH) and biceps femoris (BF). Fourteen subjects performed(More)
