OBJECTIVE The brain is one of the main targets of hypertension. However, little is known about the relation between hypertension and motor performances. We studied the association between hypertension and walking speed in a cohort of elderly people. METHODS Analyses are based on participants (65-85 years) from the Dijon (France) center of the Three-City study (n = 3604), followed every 2 year...

A set of test samples, all containing ultrasonically equivalent tissue-mimicking material, was produced and measurements of ultrasonic speed and ultrasonic attenuation coefficients were made at seven laboratories using various techniques. The ultrasonic speed values agree well with one another, having a spread of about 0.3 per cent; thus, speed values for tissue parenchyma appearing in the lite...

Our program benchmarks and simulations of novel circuits indicate that large-window processors are feasible. Using our redesigned superscalar components, a large-window processor implemented in today’s technology can achieve an increase of 10–60% (geometric mean of 31%) in program speed compared to today’s processors. The processor operates at clock speeds comparable to today’s processors, but ...

objective: the present study aimed to evaluate the effect of parenting education on improvement of reading and writing disabilities in children. methods: a randomized controlled trial was done on primary school students with reading and writing disabilities and their mothers. the subjects were divided into three groups with 26 members in each group. the first group (mothers’ education group) re...

SIR—The concept of ‘frailty’ has been used to identify older adults at increased risk for disability [1, 2]. A major obstacle to developing primary prevention strategies for frailty is the lack of clinical markers of early frailty, especially among high functioning older adults. The Physical Performance Battery (PPB) has been reported to predict disability in older adults [3, 4], but its associ...

performances of electronic and mechanical draft control systems on a mf399 tractor were the objectives of the study to be evaluated and compared under field conditions. hence, the effects of two draft control systems (mechanical and electronic) under four ground speed levels and three set values of draft levels on rear wheel slippage, fuel consumption, compressive force within the top link and ...

OBJECTIVES to establish reference values for both comfortable and maximum gait speed and to describe the reliability of the gait speed measures and the correlation of selected variables with them. DESIGN descriptive and cross-sectional. METHODS subjects were 230 healthy volunteers. Gait was timed over a 7.62 m expanse of floor. Actual and height normalized speed were determined. Lower extre...

PURPOSE The purposes of this study were to provide an update to the ambulatory distance requirements for community ambulation and to update gait speed performance and requirements at intersections. METHODS Distances were measured at 9 types of sites using a rolling measuring device in accordance with the protocol set forth by Lerner-Frankiel and associates. The 9 types of sites were supermark...

ISSN 1650-1977 Objective: To compare the effects of speed-dependent treadmill training on gait and balance performance in patients with sub-acute stroke. Design: Single-blinded randomized controlled trial. Subjects: A total of 26 patients with sub-acute stroke wer...

highway, where each car travels at a constant speed. Assume that the distribution of the speeds is the same throughout the length of the highway. You adjust your speed so that during a given time unit you overtake the same number of cars as the number of cars that overtake you. Does this mean that your speed is the median of the speeds of the cars on the highway? Surprisingly, the answer is no!...
