Attentional focus on supra-postural tasks affects postural control.
We examined whether the attentional focus adopted on a supra-postural task has an influence on postural control. Similar to Riley, Stoffregen, Grocki, and Turvey (Human Movement Science 18 (1999) 795), participants were instructed to stand still while lightly touching a loosely hanging sheet with their fingertips. However, instructions varied slightly under two conditions: Participants were eit...
متن کاملGender affects sympathetic and hemodynamic response to postural stress.
We tested the hypothesis that differences in sympathetic reflex responses to head-up tilt (HUT) between males (n = 9) and females (n = 8) were associated with decrements in postural vasomotor responses in women. Muscle sympathetic nerve activity (MSNA; microneurography), heart rate, stroke volume (SV; Doppler), and blood pressure (Finapres) were measured during a progressive HUT protocol (5 min...
متن کاملNeck muscle fatigue affects postural control in man.
We hypothesised that, since anomalous neck proprioceptive input can produce perturbing effects on posture, neck muscle fatigue could alter body balance control through a mechanism connected to fatigue-induced afferent inflow. Eighteen normal subjects underwent fatiguing contractions of head extensor muscles. Sway during quiet stance was recorded by a dynamometric platform, both prior to and aft...
متن کاملStress exposure and postural control in young females.
The aim of this study was to determine if heightened stress had an adverse affect on the postural control of 14 young right‑handed females during quiet standing in either the presence or the absence of visual input. The level of stress was evaluated by measuring the free cortisol response to awakening (cortisol awakening response; CAR) and by employing the perceived stress scale (PSS). Overall ...
متن کاملFalls 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...
