PURPOSE: To identify the modifiable lower extremity kinematic dysfunction during walking gait associated with persistent ankle pain in middle-aged adults.

METHODS: Ten individuals with persistent ankle pain (9F, 1M; 55.4±6. 52 years; 166.80±6.73 cm; 78.24±25.05 kg) and nine matched uninjured controls (8F, 1M; 53.0±5.79 years; 168.2±6.06 cm; 75.81±24.46 kg) volunteered for the study. Three-dimensional lower extremity kinematics and kinetics were collected during five barefoot walking trials at a self-selected speed. Lower extremity sagittal and frontal joint positions were used to calculate joint ROM and maximum joint position during 1 st double-limb support, single-limb support, and 2 nd double-limb support. Position at initial contact in the sagittal and frontal plane was also calculated. MANOVA tests assessed group differences with an alpha level of p< 0.05. Significant tests were followed by independent t …
