We previously published vestibular perceptual thresholds and performance in the Modified Romberg Test of Standing Balance in 105 healthy humans ranging from ages 18 to 80 (1). Self-motion thresholds in the dark included roll tilt about an earth-horizontal axis at 0.2 and 1 Hz, yaw rotation about an earth-vertical axis at 1 Hz, y-translation (interaural/lateral) at 1 Hz, and z-translation (vertical) at 1 Hz. In this study, we focus on multiple variable analyses not reported in the earlier study. Specifically, we investigate correlations (1) among the five thresholds measured and (2) between thresholds, age, and the chance of failing condition 4 of the balance test, which increases vestibular reliance by having subjects stand on foam with eyes closed...

BACKGROUND: In Parkinson's disease (PD) patients, fluctuations in symptoms commonly occur after many years of dopamine replacement therapy. The so-called wearing-off phenomenon exists of both motor and non-motor symptoms, such as rigidity and anxiety. Current treatment options are limited and an integrated approach is needed to address the complex interactions between motor and non-motor symptoms. Since wearing-off is eventually inevitable, treatment needs to focus on coping, acceptance and self-efficacy...

Classical ballet involves the performance of complex movements that require high-level motor skills and good postural control. This study explored postural sway in passé en demi-pointe position in dancers and compared single-leg standing sway (with and without visual restriction) between dancers and non-dancers. Fourteen professional dancers and 14 sex- and age-matched volunteers who were not ballet dancers participated in the study. Participants stood on a force plate on the dominant leg in the following positions: 1...

The purpose of the study was to investigate the individual and combined effects of applying light finger touch and performing a cognitive task on postural sway. Fourteen healthy young individuals stood on the force platform with light finger touch contact applied to an external stable structure and without finger touch. Both tasks were performed with and without a cognitive task (counting backward from a randomly chosen three-digit number). The center of pressure excursion and velocity as well as sway area were calculated...

This study addresses the question of how posture and movement are oriented with respect to the direction of gravity. It is suggested that neural control levels coordinate spatial thresholds at which multiple muscles begin to be activated to specify a referent body orientation (RO) at which muscle activity is minimized. Under the influence of gravity, the body is deflected from the RO to an actual orientation (AO) until the emerging muscle activity and forces begin to balance gravitational forces and maintain body stability...

Elbow flexor force steadiness (FS) depends on strength and decreases with age. Achilles tendon mechanics effect standing balance and isometric plantarflexion FS. This study investigated the influence of distal biceps brachii (BB) tendon mechanics and elbow flexor strength on age-related decline in FS. Nine young (23±2 years) and 9 old (77±5 years) males performed submaximal isometric elbow flexion tasks at low (2.5, 5, 10% maximal voluntary contraction (MVC)) and high (20, 40, 60, 80%MVC) forces in a neutral forearm position...

Impaired balance resulting from reduced postural control occurs with aging and various medical conditions. Sensory input for balance control is provided by the visual, vestibular and somatosensory systems. Previous research suggests that increased proprioceptive feedback from various lower extremity devices improves balance. Mixed results have been reported with the use of orthoses such as ankle foot orthoses (AFOs). In this study, 20 healthy subjects wore footplates in their shoes or straps around their lower legs in order to imitate the somatosensory feedback produced by wearing AFOs, but without providing ankle restriction...

The original version of the hygiene hypothesis suggested that infections transmitted early in life by "unhygienic contact" prevented allergies. Examples were endemic fecal-oral infections by viral, bacterial, or protozoic pathogens, such as hepatitis A virus, Helicobacter pylori, or Toxoplasma gondii. Later, this concept also included microorganisms beyond pathogens, such as commensals and symbionts, and the hygiene hypothesis was extended to inflammatory diseases in general. An impressive illustration of the hygiene hypothesis was found in the consistent farm effect on asthma and allergies, which has partly been attributed to immunomodulatory properties of endotoxin as emitted by livestock...

The purpose of the current study was to assess the effectiveness of a specific exercise intervention of mechanisms to control dynamic postural stability under unstable conditions in old adults. Forty-seven old adults (65-80 years) were assigned to two experimental groups (muscle strength group, n=15, perturbation-based group, n=16) and a control group (n=16). The strength group performed resistance exercises for legs and trunk muscles, while the perturbation-based group exercised mechanisms of dynamic stability under unstable conditions...

This study aims to investigate the effect of a somatosensory cueing on gait disorders in subjects with Parkinson's disease (PD). After having performed stepping in place and timed up and go assessing tasks, 13 participants with PD were equipped with an electrical stimulator and an inertial measurement unit (IMU) located under the lateral malleolus on the sagittal plane. Electrodes were positioned under the arch of the foot and electrical stimulation (ES) parameters (five 500 µs/phase charge-balanced biphasic pulses delivered at 200 Hz, repeated four times at 10 Hz) adjusted to deliver a sensitive signal...

This study aimed to investigate the variability in postural sway patterns during quiet standing in stroke survivors. The postural sway was measured in 19 stroke survivors, as well as 19 healthy demographically matched participants, at 3 levels of postural difficulty (rigid surface with closed and open eyes, and foam surface with closed eyes), and 3 levels of cognitive difficulty (without a cognitive task, easy and difficult cognitive tasks). Both linear analyses (the amount of postural sway variability, including the standard deviation of the COP velocity in both the anteroposterior (AP) and mediolateral (ML) directions), as well as non-linear analyses [the temporal structure of the COP variability, including % Recurrence, % Determinism, Shannon Entropy, Trend and the maximum diagonal line (D max)] were employed...

OBJECTIVE: Rehabilitation interventions contribute to recovery of impaired postural control, but it remains a priority to optimize their effectiveness. A promising strategy may involve transcranial direct current stimulation (tDCS) of brain areas involved in fine-tuning of motor adaptation. This study explored the effects of cerebellar tDCS (ctDCS) on postural recovery from disturbance by Achilles tendon vibration. METHODS: Twenty-eight healthy volunteers participated in this sham-ctDCS controlled study...

Simple methods for quantitative evaluations of individual motor performance are crucial for the early detection of motor deterioration. Sit-to-stand movement from a chair is a mechanically demanding component of activities of daily living. Here, we developed a novel method using the ground reaction force and center of pressure measured from the Nintendo Wii Balance Board to quantify sit-to-stand movement (sit-to-stand score) and investigated the age-related change in the sit-to-stand score as a method to evaluate reduction in motor performance...

BACKGROUND AND PURPOSE: A growing body of literature substantiates that Tai Chi is a form of exercise that may help older adults increase strength, improve balance, lower fall rates, and experience less fear of falling. Few studies, however, offer controlled experimental design and simultaneously investigate multiple factors known to contribute to fall risk. The purpose of this study was to compare performance on measures relating to fall risk (strength, balance, functional mobility, and fear of falling) in older community-dwelling adults who participated in a community-based Tai Chi program with a control group of their peers who had no Tai Chi training over the same time period...

PURPOSE: Medicare's merit-based incentive payment system and narrowing of physician networks by health insurers will stoke clinicians' and policy makers' interest in care delivery attributes associated with value as defined by payers. METHODS: To help define these attributes, we analyzed 2009 to 2011 commercial health insurance claims data for more than 40 million preferred provider organization patients attributed to over 53,000 primary care practice sites. We identified sites ranking favorably on both quality and low total annual per capita health care spending ("high-value") and sites ranking near the median ("average-value")...
