The purpose of our study was to analyze the effects of upper-body fatigue and lower-body fatigue on post-exercise standing balance. Force plates were used to assess static balance by measuring the displacement of the Center of Pressure (COP) while subjects stood on the plate. Ten healthy male undergraduate students (mean age 20.7 years, SD = 1.3) each participated in one session. All subjects w...

OBJECTIVES While balance in young and older adults is known to change with the threat of standing on elevated surfaces, the potential for social anxiety to influence emotional states and balance performance during a clinical assessment is currently unknown. METHODS Nineteen young and 19 older healthy female adults volunteered for the study. The effects of age and clinical assessment on balanc...

The control of standing is a complicated task that involves the action of muscles distributed over the whole body. Forces arising from gravity, external events or our own actions all tend to disturb the unstable equilibrium that preserves posture. For the central nervous system the problem of standing can be cast in terms of finding appropriate relations among body segments to maintain the desi...

OBJECTIVE To evaluate the short-term effects of vestibular rehabilitation on symptom, disability, balance, and postural stability in patients with chronic unilateral vestibular dysfunction. DESIGN Randomized controlled trial. SETTING Department of Physical Medicine and Rehabilitation, University Hospital. PARTICIPANTS Patients (N=42) with chronic vestibular dysfunction were divided into e...

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 without a...

OBJECTIVES Assessment of the association of blood pressure measurements in supine and standing position after a postural change, as a proxy for blood pressure regulation, with standing balance in a clinically relevant cohort of elderly, is of special interest as blood pressure may be important to identify patients at risk of having impaired standing balance in routine geriatric assessment. MA...

Taekwondo (TKD) is a popular sport among adolescents. This study aims to (a) compare the balance performance between adolescent TKD practitioners at different levels of expertise with nonpractitioners and (b) determine the sensory system(s) that contributed to the balance function in adolescents with and without TKD training. Subjects with >5 years of TKD training (n = 11), <4 years of training...

PURPOSE Sample entropy (SampEn) is an analysis to evaluate movement complexity of the center of pressure (COP). A lower value of SampEn indicates lower complexity of COP variability, that is, rigidity, and lower degrees of freedom. Previous studies reported the association of increased SampEn with improved standing balance ability in young subjects. However, no studies have examined these relat...

BACKGROUND The purpose of this study was to investigate the changes in the Power Spectral Density (PSD) of the electroencephalogram (EEG) during 8 common sensorimotor balance training tasks of varying difficulty in single-limb trans-tibial amputees. MATERIAL AND METHODS Eight sensorimotor balance exercises, including alteration in vision, base of support, and surface compliance, were used to ...
