Refining Therapeutic Interventions

Older populations require efficacious therapeutic interventions as they are at risk for cognitive and physiological decline. Our research aims to improve both the design (e.g., frequency, intensity, type, time) and delivery (e.g., timing, use of technology, group-based vs individualized) of interventions.

Refining Fall Risk Assessments

Some falls-risk screening tools may not be sensitive to detect impairments or have established psychometric properties that aid in interpretation of findings. Our research aims to improve fall-risk screening procedures by implementing methods such as: defining risk-factors unique to specific populations (e.g., older adults with recurrent falls), establishing psychometric properties of assessment tools (e.g., minimal clinical importance difference), and examining factors that influence screening procedures (e.g., repeated testing procedures).

Understanding Mobility and Cognition

Impairments in mobility and cognition are commonly observed together in aging populations and are important falls-risk factors. Our research aims to provide a better understanding of mobility and cognitive strategies in varying conditions, such as changing task parameters, altering sensory input, and comparing populations, in order to inform assessments and interventions.
