Our ability to balance upright provides a stable platform perform daily activities. Balance deficits associated with various clinical conditions may affect activities of living, highlighting the importance quantifying standing in ecological environments. Although typically performed laboratory settings, growing availability low-cost inertial measurement units (IMUs) allows assessment real world. However, it is unclear how many IMUs are required adequately estimate linear displacements centre...
The major disadvantage of current clinical tests that screen for balance disorders is a reliance on an examiner's subjective assessment equilibrium control. To overcome this we investigated, using quantified measures trunk sway, age-related differences normal subjects commonly used tests.Three age groups were tested: young (15-25 years; n = 48), middle-aged (45-55 50) and elderly (65-75 49). Each subject performed series fourteen tasks similar to those included in the Tinetti Clinical Test...
We investigated the effects of ageing on balance corrections induced by sudden stance perturbations in different directions. Effects were examined biomechanical and electromyographic (EMG) recordings from a total 36 healthy subjects divided equally into three age groups (20–34, 35–55 60–75 years old). Perturbations consisted six combinations support‐surface roll (laterally) pitch (forward‐backward) each with 7.5 deg amplitude (2 pure pitch, 4 pitch) delivered randomly. To reduce stimulus...
<b>Objective:</b> We investigated trunk control, protective arm movements, and electromyographic responses to multidirectional support-surface rotations in patients with Parkinson's disease (PD), aiming better understand the pathophysiology underlying postural instability PD, on off antiparkinson medication. <b>Methods:</b> Ten PD were compared 11 age matched healthy controls. Seven also tested without (OFF) All subjects received rotational perturbations (7.5 deg amplitude) that randomly...
One possible factor influencing the control of upright stance is perceived threat to one's personal safety, i.e. balance confidence. We explored this by examining stationary when standing on an elevated platform under various conditions reduced visual and vestibular inputs. Twenty-eight adults (14 male 14 female, mean age = 23.5 years) participated in experiment. Postural was examined recording amplitude variability (RMS) power frequency (MPF) center pressure excursions (COP) over a 2-minute...
Ecological validity is a relatively new concept in hearing science. It has been cited as relevant with increasing frequency publications over the past 20 years, but without any formal conceptual basis or clear motive. The sixth Eriksholm Workshop was convened to develop deeper understanding of for purpose applying it research consistent and productive manner. Inspired by debate within field psychology, taking into account World Health Organization's International Classification Functioning,...
It has been just over 20 years since the effects of height-induced threat on human postural control were first investigated. Raising height support surface which individuals stood increased perceived consequences instability and generated changes. Since this initial work, converging evidence accumulated supporting efficacy using to study emotions confirming a direct influence threat-related changes in arousal, anxiety, fear falling all aspects control, including standing, anticipatory,...
Abstract Vestibular‐evoked balance responses are facilitated when faced with threats to stability. However, the extent which these sensorimotor adaptations covary changes in emotional and autonomic state remains unclear. This study repeatedly exposed individuals same postural threat while vestibular‐motor were probed using stochastic vestibular stimulation (SVS; 2–25 Hz). allowed be manipulated within environment determine if vestibular‐evoked coupled emotional/autonomic induced by or a...
To determine if increases in balance challenge influenced concomitant change self-efficacy, state anxiety and physiological arousal, these changes were correlated with standing young older adults.A 2 x between- (age) by within-subject (balance challenge) factorial design.quiet trials performed on low high support-surface heights a research laboratory.14 Young (22-31 years) 14 (60-83 adults no known neurological or disorders, falls within the last year.Forceplate-derived measures of balance,...
Previous studies have shown significant effects of increased postural anxiety in healthy young individuals when standing quietly or performing voluntary tasks. However, little is known about the influence on reactive control. The present study examined how influenced reactions to unexpected surface rotations multiple directions. Ten adults (mean age: 25.5 yr, range: 22-27 yr) were required recover from support (7.5 degrees amplitude, 50 degrees/s velocity) delivered six different directions...
