Abstract

Aberrant loading is a mechanism by which individuals with chronic ankle instability (cai) may negatively impact cartilage health and therefore long-term health outcomes. We aimed to quantify walking vertical ground reaction force (vgrf) component differences between those with and without cai. Participants (n = 36) walked barefoot overground at a self-selected comfortable pace. Normalized peak vgrf, time to peak vgrf, and normalized loading rate were calculated. Higher normalized loading rates (cai: 5.69 ± 0.62 n/bw/s; controls: 5.30 ± 0.44 n/bw/s, p =.034) and less time to peak vgrf (cai: 1.48 ± 0.18 s; controls: 1.62 ± 0.16 s, p =.018) were observed in those with cai. In conclusion, those with cai demonstrate a higher normalized loading rate and less time to peak vgrf compared to controls.
