The linear vestibulo-ocular reflex (LVOR) to surge (fore-aft) translation has complex kinematics varying with target eccentricity and distance. To determine normal responses and aging changes, 9 younger [age, 28 +/- 2 (SE) yr] and 11 older subjects (age, 69 +/- 2 yr) underwent 0.5 g whole body surge transients while wearing binocular scleral search coils. Linear chair position and head accelera...
Purpose: As many older people fall during dual tasks, we aimed to examine the effect of different cognitive loads on learning gait stability in younger and older adults. Methods: 10 younger (Mean±SD age: 25.91±3.42 years) and 10 older adults (Mean±SD: 66.65±4.28 years) were healthy volunteers without a history of falls. They were asked to do three tasks on a treadmill with cognitive load (none...
conclusions although the frequency of hbsag seropositivity in the present study was close to that observed in the overall iranian population, the seroprevalence of anti-hbc was higher, possibly due to the exposure of the elderly to more risk factors. the risk factors were similar. these included a history of blood transfusions, cupping, hospital admission, endoscopy, or familial hbv/hcv infecti...
To assess age-related differences in cortical activation during form perception, two classes of visual textures were shown to young and older subjects undergoing positron emission tomography (PET). Subjects viewed even textures that were rich in rectangular blocks and extended contours and random textures that lacked these organized form elements. Within-group significant increases in regional ...
objectives: this study aimed to identify elderly fallers and non-fallers by balance test under dual tasks conditions. methods & materials: this study was an analyze-comparative study. subjects were from three park of tehran. subjects were 20 older adults with outhistory of falls (aged 75.95±6.28 years) and 21 older adults with a history of 2 or more falls in the previous one year (aged 72.50±7....
