An estimated 45% of all sports injuries involve the ankle. Of those with ankle sprains, about 1 out of 3 people report residual symptoms that classify as chronic ankle instability (CAI).
CAI is a common musculoskeletal injury typically attributed to deficits in single limb balance. Historically, clinicians and researchers have conducted balance assessments based on center of pressure displacement measurements, however more recently, time-to-boundary (TTB) has been utilized because of its ability to discriminate postural control deficits present in subjects with CAI.
Time-to-Boundary is a validated, reliable, spatiotemporal (range and velocity) measurement tool that estimates the time an individual has to make postural corrections in order to maintain balance.
