• There is considerable variation in the level of physical impairment between age groups. The prevalence of reported physical functional limitation is surprisingly high at the youngest end of the sample, with 43% of respondents in their 50s reporting difficulty with mobility and 13% reporting difficulty with a basic activity of daily life (self-care). At the same time, most (58%) of the respond...

The self-organizational ability of ad-hoc Wireless Sensor Networks (WSNs) has led them to be the most popular choice in ubiquitous computing. Clustering sensor nodes organizing them hierarchically have proven to be an effective method to provide better data aggregation and scalability for the sensor network while conserving limited energy. It has some limitation in energy and mobility of nodes....

The prevalence of hypertension among people with disabilities is not well understood. We combined data from the 2001-2010 National Health and Nutrition Examination Survey to obtain estimates of hypertension prevalence by disability status and type (cognitive, hearing, vision, or mobility limitation) and assess the association between disability and hypertension. Overall, 34% of adults with disa...

Insulator-based dielectrophoresis (iDEP) is a powerful tool for separating and characterizing particles, yet it is limited by a lack of quantitative characterizations. Here, this limitation is addressed by employing a method capable of quantifying the DEP mobility of particles. Using streak-based velocimetry the particle properties are deduced from their motion in a microfluidic channel with a ...

BACKGROUND A 37-year-old female with a hyperkinetic movement disorder due to chorea-acanthocytosis developed severe painful degenerative arthritis of her left knee as a consequence of repetitive involuntary flexion and extension dystonic and ballistic movements. CASE REPORT Despite profound limitation in her mobility a total knee replacement was successfully undertaken. DISCUSSION The case ...

"Persons with disabilities" is a vague designation that might not always be understood. Persons with disabilities are persons with limitations in hearing, vision, mobility, or cognition, or with emotional or behavioral disorders. What they have in common is that they all experience a significant limitation in function that can make it harder to engage in some activity of daily living without ac...

BACKGROUND There is limited evidence supporting the hypothesized environment-disability link. The objectives of this study were to (a) identify the prevalence of community mobility barriers and transportation facilitators and (b) examine whether barriers and facilitators were associated with disability among older adults with functional limitations. METHODS Four hundred and thirty-five partic...

Due to the chemical stability and perfection of Carbon Nanotubes (CNTs) structure, carrier mobility is not affected by processing and roughness scattering as it is in the conventional semiconductor channel. Therefore, CNTs are being considered as viable candidates for high-speed applications. The mobility and saturation velocity are the two important parameters that control the charge transport...

BACKGROUND Life course exposure to violence may lead to disability in old age. We examine associations and pathways between life course violence and mobility disability in older participants of the International Mobility in Aging Study (IMIAS). METHODS A cross-sectional study using IMIAS 2012 baseline. Men and women aged 65-74 years were recruited at 5 cities (n=1995): Kingston and Saint-Hyac...
