- Abstract
- The purpose of this study was to examine if a more affordable over the counter orthotic can be used by the public to assist people with unstable ankles with ankle joint stiffness, pre-activation levels of the peroneus longus (PL), and time to stabilization (TTS). Forty individuals (20 unstable ankles and 20 stable ankles) repeated three randomized tasks with and without orthotics in a pretest-posttest design. The tasks included: 1) A single leg drop landing task in a) frontal and b) sagittal planes and 2) ankle joint stiffness utilizing an ankle cradle with inversion perturbation. Results revealed no interaction effects on ankle joint stiffness, pre-activation levels of the PL, and TTS in both the sagittal and frontal planes. We observed the unstable ankle group took longer to stabilize in both the sagittal and frontal planes. We also noted that ankle joint stiffness decreased in both groups in the orthotic condition.
