Research Themes

Research Relevance

Mobility is defined as the ability to move one's body in space. With aging and the onset of disease, interactions among intrinsic determinants (secondary disabilities related to aging and disease) and extrinsic determinants (e.g., housing, community, transportation, and mobility aids) affect mobility and its underlying activities among older adults. Traditionally, studies of those determinants and their interactions are based on indirect measurements (e.g., questionnaires) or direct measurements (e.g., clinical or laboratory assessment of abilities) which reflect neither the everyday reality of the mobility of those affected nor their abilities in their environments.

The objective of Prof. Boissy's research program is to develop measurements, tools, and technologies based on actimetrics (the objective and quantified analysis of the activity(-ies) of an individual in his or her environment using sensors) in order to: 1. Define and understand mobility and the activities of older adults in their natural environments; 2. Analyze the impacts of aging and disease on mobility and on these activities while taking into account individual factors; and 3. Study the effects of interventions to maintain and re-establish mobility in older adults. The ultimate objective of the program is to transfer the measurement methods to the study of a variety of clinical issues such as the modelling in both the home and the community of the mobility of older adults or of those with Parkinson's disease; the characterization of profiles for motorized wheelchair use and their impact on mobility and the social participation of users. Prof. Boissy collaborates in interdisciplinary initiatives along with other researchers and health care professionals, notably in geriatrics, orthopedics, rehabilitation, traumatology, neurology, and ethics.
