To clarify the neuromotor effects of long-term exposure to mixed organic solvents, postural sway and tremor were measured in 62 solvent workers of four Buddhist altar manufacturing factories who had worked for 1-46 (mean 12) yr. By using the passive gas sampler, 8-h time-weighted average concentrations in the workers were estimated to be 0.02-8.7 ppm for toluene, 0.02-7.7 ppm for xylene, 0.02-5...
UNLABELLED The aim of this study was to evaluate the relation between the sensory and anthropometric variables in the quiet standing. METHODS One hundred individuals (50 men, 50 women; 20-40 years old) participated in this study. For all participants, the body composition (fat tissue, lean mass, bone mineral content, and bone mineral density) and body mass, height, trunk-head length, lower li...
Electroencephalographic (EEG; Be-plus Eb-Neuro) and stabilogram (RGM) data were simultaneously recorded in 19 elite karate and 18 fencing athletes and in 10 non-athletes during quiet upright standing at open- and closed-eyes condition in order to investigate the correlation between cortical activity and body sway when the visual inputs are available for balance. Our working hypothesis is that, ...
[Purpose] The purpose of this study was to determine the functional differences of the plantar flexion muscles of the hallux and lesser toes during the single leg stance by comparing postural sway in different conditioning contraction interventions. [Subjects] Thirty-four healthy, young males and females participated in this study. [Methods] The front-back and right-left direction components of...
OBJECTIVE To study the association in a group of battery manufacturing workers between computerised postural sway parameters and present concentrations of blood lead (PPb), index of cumulative blood lead years (CBI), and cumulative blood lead at different years of exposure (CPbYs). METHODS Postural stability was investigated with a computerised postural sway measurement system in 60 workers e...
OBJECTIVE To evaluate the effects of coordination exercise on postural stability in older individuals by Chinese shadow boxing, Tai Chi Chuan (TCC). DESIGN Cross-sectional study. SETTING Research project in a hospital-based biomechanical laboratory. PARTICIPANTS The TCC group (n = 25) had been practicing TCC regularly for 2 to 35 years. The control group (n = 14) included healthy and acti...
Age-related differences in efficiency of visual and vibrotactile biofeedback for balance improvement
OBJECTIVES: The purpose of this study was to determine the effectiveness of visual (VF) and vibrotactile (TF) biofeedback obtained from the lower trunk (L5) tilts signal and their combination (VF+TF) in reducing postural sway in young and elderly people. METHODS: Twenty healthy elderly subjects (8 males, mean age 74 years) and 20 healthy young subjects (7 males, mean age 27 years) were tested i...
[Purpose] The purpose of the current study was to investigate the influence of footwear type on postural sway of hemiparetic stroke patients. [Subjects] Thirty-two stroke patients who were undergoing a rehabilitation program were recruited on a voluntary basis from local rehabilitation unit. [Methods] This study had a single-group repeated-measures design. The Good Balance system was used to me...
Background: Upright sitting is one of the first developmental motor milestones achieved by infants, and sitting postural sway provides a window into the developing motor control system. A variety of posture sway measures can be used, but the optimal measures for infant development have not been identified. Methods: We have collected sitting postural sway data from two groups of infants, one wit...
