Dorsiflexion and dynamic postural control deficits are present in those with chronic ankle instability.

Objectives: To determine if differences in weight-bearing ankle dorsiflexion range of motion (DFROM) and Star Excursion Balance Test (SEBT) reach distances were present between participants with chronic ankle instability (CAI) and healthy individuals. A secondary objective was to re-examine the relationship between these measures in participants with and without CAI.

Design: Case-control.

Dorsiflexion range of motion significantly influences dynamic balance.

The purpose of this study was to examine the relationships between dorsiflexion range of motion on the weight-bearing lunge test (WBLT) and normalized reach distance in three directions on the Star Excursion Balance Test (SEBT). Thirty-five healthy adults (14 males, 21 females, age: 25.9±6.
