OBJECTIVE to identify sensorimotor and psychosocial determinants of 3-year incident mobility disability. DESIGN prospective. SETTING population-based sample of community-dwelling older persons. PARTICIPANTS community-living middle-aged and older persons (age: 50-85 years) without baseline mobility disability (n = 622). MEASUREMENTS mobility disability, defined as self-reported inability...

statement of problem: following the increasing use of composites in restoring anterior and posterior teeth, problems due to its technique sensitivity have become a major concern. one of these problems is the possibility of contamination of dentin with saliva, blood and/or gingival fluid in different stages of bonding procedure, even with application of different methods of isolation. however, b...

The use of polymer in hot mix asphalt production has remarkably in recent decades. Destruction due to moisture in hot mix asphalt is of basic matters about flexible pavement durability. In recent decades different ways have been used to evaluate moisture Sensitivity of HMA which some of them are simple with low cost and some are complicated with more reliable results. In this research the effec...

Until recently coccidioidin has been the only antigenic preparation available for detecting delayed dermal sensitivity induced by an experience with Coccidioides immitis. It is prepared from autolysates of the mycelial phase (saprophytic) of the fungus. A more sensitive reagent, spherulin, was developed in 1969 from the spherule phase (parasitic) of the organism. Use of spherulin showed that co...

PURPOSE Insulin resistance is thought to be a core defect in the pathophysiology of obesity-related comorbidities in children, such as type 2 diabetes. Exercise training is known to improve insulin resistance and reduce the risk of type 2 diabetes in adults. However, very little is known regarding the effects of exercise on insulin resistance in youth. Therefore, we examined the effects of a 16...

Stereoscopic vision uses the disparity between the images received by the two eyes to derive three-dimensional estimates. Here, we were interested in providing a measure of the strength of binocular vision alternate to disparity processing. In particular, we wanted to assess the spatial dependence of sensitivity to detect interocular correlation (IOC). Thus we designed dichoptic stimuli compose...

BACKGROUND the study of factors associated with age-related gait decline may assist in developing methods to preserve mobility in older people. OBJECTIVE to examine the associations between sensorimotor factors relevant to ageing and gait in the general older population. DESIGN cross-sectional population-based study. METHODS participants aged 60-86 years (n = 278) were randomly selected u...

Tests of vision, vestibular function, peripheral sensation, strength, reaction time, balance and gait were administered to 183 community-dwelling women aged 22-99 years. Walking speed, stride length and cadence declined with age with corresponding increases in stance duration and percentage of the stride in the stance phase. Visual acuity and contrast sensitivity, tactile and vibration sense in...
