Postural adjustment errors during lateral step initiation in older and younger adults

Postural adjustment errors reveal deficits in inhibition during lateral step initiation in older adults.

Postural dual-task studies have demonstrated effects of various executive function components on gait and postural control in older adults. The purpose of the study was to explore the role of inhibition during lateral step initiation. Forty older adults participated (range 70-94 yr). Subjects stepped to the left or right in response to congruous and incongruous visual cues that consisted of lef...

Postural adjustment errors reveal deficits in inhibition during lateral step

23 Postural dual task studies have demonstrated effects of various executive function 24 components on gait and postural control in older adults. The purpose of the study was 25 to explore the role of inhibition during lateral step initiation. Forty older adults 26 participated (range 70-94 y). Subjects stepped to the left or right in response to 27 congruous and incongruous visual cues that co...

Lateral step initiation behavior in older adults.

Older adults have varied postural responses during induced and voluntary lateral stepping. The purpose of the research was to quantify the occurrence of different stepping strategies during lateral step initiation in older adults and to relate the stepping responses to retrospective history of falls. Seventy community-ambulating older adults (mean age 76 y, range 70-94 y) performed voluntary la...

Falls and postural control in older adults with cataracts

Background: There is increasing evidence that visual impairment contribute to falling. The aim of this study was to determine the influence of vision impairment of old adult patients with cataract on the occurrence of falls and postural control. Methods:According to the results of screening ophthalmic examination, 48 cataract patients (mean±SD aged 68.5 ± 6.08 yrs.) and 50 individuals withou...
