Although motor output of the postural function clearly influences postural performance in young and older subjects, no relationship has been formally established between them. However, the relationship between lower-extremity muscle strength/power and postural performance is often pointed out, especially in older subjects. In fact, the influence of motor output may vary according to the postura...

The present study was planned to investigate the efficiency of explicit teaching and adequacy of the L2 learners' exposure to L2 input in academic contexts in Iran. The case at hand was the acquisition of referential, quasi and expletive subject pronouns, as three different types of obligatory subjects in English. 96 Iranian EFL learners were selected from two universities in Isfahan. They were...

background : malnutrition represents an important issue in older adults; unfortunately, there is lack of data concerning this topic in lebanon. this paper aims to provide a description of nutritional status and its correlates in older adults living in long stay institutions situated in beirut. methods : this cross-sectional study was conducted in three long stay institutions in beirut in 2012. ...

We compared differences in isometric strength between older adults who have undergone elective unilateral total hip arthroplasty (THA) and completed rehabilitation with a population of community-dwelling older adults who have not had THA. The study was a cross-sectional design, and 22 unilateral THA subjects and 38 community-dwelling older adults participated. THA subjects received on average 1...

BACKGROUND Aging is associated with a reduction in gait velocity, which is due to a shortened step length. This study investigated the relationship between joint kinetics and step length. METHODS Three-dimensional gait kinematics and kinetics were measured during usual pace gait in 26 older subjects (average age 79) and in 32 young subjects (average age 26). Gait measures were obtained at max...

Visual perceptual learning (VPL) with younger subjects is associated with changes in functional activation of the early visual cortex. Although overall brain properties decline with age, it is unclear whether these declines are associated with visual perceptual learning. Here we use diffusion tensor imaging to test whether changes in white matter are involved in VPL for older adults. After trai...

OBJECTIVE To study free- and protein-bound cobalamin absorption and the correlation with atrophic gastritis in healthy middle-aged and older subjects. DESIGN A cross-sectional study. PARTICIPANTS Fifty-two healthy subjects, aged 26 to 87 years, apparently free from conditions known to influence the cobalamin status. Middle-aged subjects were defined as those younger than 65 years of age (me...
