As emphasized in the WHO's ICF classification system (International Classification of Functioning, Disability, and Health), mobility is a critical component to physical and mental health and independence among older adults. Mobility includes but is not limited to transference, basic ambulation, and walking, and limited mobility is associated with sarcopenia, decubitus ulcers, falls, fractures, increased BMI, and isolation/loss of social interaction. The antecedents and corollaries of loss of mobility are often mutable and environmental, and assistive technology can compensate for mobility impairment.

We invite authors to submit original research and review articles that seek to identify advances in our understanding on how to prevent or minimize the impact of mobility loss in older populations, and, where possible, the expansion of mobility. We invite manuscripts that approach mobility at any ecological level from the individual to policy as well as those ranging from basic science application to community practice. We also invite submissions from traditional aging-related professions such as gerontology, geriatrics, and social work as well as nontraditional professions such as architecture, urban planning, and transportation engineering. Potential topics include, but are not limited to:

• Advances in the clinical measurement of mobility through the ICF and other tools
• Underlying biologic causes and/or risk factors associated with loss of mobility
• Advances in assistive devices and technology to promote mobility
• Environmental factors associated with restriction/promotion of mobility
• Public health and policy initiatives promoting mobility
• Epidemiology of mobility
• Evidence-based interventions that promote mobility

Before submission authors should carefully read over the journal's Author Guidelines, which are located at http://www.hindawi.com/journals/jar/guidelines/. Prospective authors should submit an electronic copy of their complete manuscript through the journal Manuscript Tracking System at http://mts.hindawi.com/ according to the following timetable:
