In older adults, maintaining balance and processing information typically interfere with each other, suggesting that executive functions may be engaged for both. We investigated associations between measures of inhibitory processes and standing postural control in healthy young and older adults. Perceptual and motor inhibition was measured using a protocol adapted from Nassauer and Halperin (20...

Humans sway. With bipedal stance on a fixed base of support, this sway causes changes in the location of the Center of Pressure as it is projected onto this base of support. Translating the base itself also causes changes in the Center of Pressure. In this study, we have developed a two-dimensional biomechanical model that uses changes in the Anterior-Posterior Center of Pressure (APCOP) to tra...

A correlation has been reported in the dental literature between temporomandibular disorders and musculoskeletal abnormalities, however, the question whether they modify body postural sway remains controversial. In the present investigation, the Craniomandibular Index was used to evaluate the clinical extension of temporomandibular joint dysfunction and related problems in 40 patients with norm...

In this paper, we have developed an efficient method for real time computation of Center of Pressure (CoP) sway area using a fast search and sort based on a numerical approximation of the Green-Gauss method. In addition, we investigated the correlations among the velocity, acceleration, path length, sway area, and mean frequency of CoP signals during quiet standing in healthy children and in ch...

OBJECTIVES To identify the extent of dual task interference between cognitive and motor tasks, (cognitive motor interference (CMI)) in sitting balance during recovery from stroke; to compare CMI in sitting balance between stroke and non-stroke groups; and to record any changes to CMI during sitting that correlate with functional recovery. METHOD 36 patients from stroke rehabilitation settings...

OBJECTIVE To investigate the relative impact of radiographic osteoarthritis (ROA) and current knee pain on lower limb physical function, quadriceps strength, knee joint proprioception, and postural sway. METHODS Using a 2x2 factorial design, 142 community derived subjects aged over 45 were divided into four subgroups based on the presence or absence of ROA (Kellgren & Lawrence>grade 2) and kn...

Postural stability becomes compromised with advancing age, but the neural mechanisms contributing to instability have not been fully explicated. Accordingly, this quantitative physiological and MRI study of sex differences across the adult age range examined the association between components of postural control and the integrity of brain structure and function under different conditions of sen...

OBJECTIVE To observe the differences in performance variables of the sit to stand transfer (as measured on the NeuroCom Balance Master) in a population of senior athletes. METHOD A convenience sample of 173 subjects aged 50 years and older. Data were obtained from voluntary participation in a health fair offered at the annual Huntsman World Senior Games in St George, Utah, USA. All sit to sta...

BACKGROUND Degradation of the somatosensory system has been implicated in postural instability and increased falls risk for older people and Parkinson's disease (PD) patients. Here we demonstrate that textured insoles provide a passive intervention that is an inexpensive and accessible means to enhance the somatosensory input from the plantar surface of the feet. METHODS 20 healthy older adul...

INTRODUCTION Obesity affects postural sway during normal quiet standing; however, the reasons for the increased postural sway are unknown. Improving muscular strength is regarded as a potential way to improve postural control, particularly for obese and overweight subjects. The purpose of this investigation is to evaluate the role of muscular strength on postural sway in obese and overweight in...
