The STRIDES Study will explore the use of gait speed as both a vital sign and digital clinical biomarker in a diverse population of older adults. This research will focus on gait speed variability and its associated health implications, including cognitive decline, sarcopenia, frailty, and an increased risk of falls. One segment of the study will examine how changes in gait speed correlate with mild cognitive impairment (MCI), particularly looking at the prevalence of motor-cognitive risk syndrome which is diminished gait speed in the context of MCI.

Progressive supranuclear palsy and corticobasal syndrome are progressive neurodegenerative diseases characterised by parkinsonian features (stiffness, slowness and tremor), balance difficulty with falls, abnormalities in the control of eye movements, difficulty with skilled movement (apraxia) and thinking problems.  We currently do not have any information on the number of people in Ireland living with these conditions.
