Ankle musculature latency measurement to varing angles of sudden external oblique perturbation in normal functionally unstable ankles
نویسندگان
چکیده
Background: Several studies have examined the reflex response of ankle musculature to sudden inversion in noninjured and injured subjects. To date, there have been no studies to determine the effect of versatile degrees & conditions of perturbation on the ankle musculature latency. The purpose of this study was to measure and determine whether there was a difference in ankle musculature latency measurements at 10°, 20°, and 30° in the oblique plane on a dual tilting platform (APS) between normal and functionally unstable ankles under different conditions of per-

Background & Aim: Peroneal reaction time measurement has been used to objectively evaluate functional instability of the ankle joint. The reliability of the method has been reported only in frontal plane, but it has not been proven in oblique plane. The purpose of this study was to determine the reliability of ankle musculature latency, peak and time of activation measurements on a tilting ...
متن کاملDeficits in peroneal latency and electromechanical delay in patients with functional ankle instability.
The purpose of this study was to compare alterations in peroneal latency and electromechanical delay (EMD) following an inversion perturbation during walking in patients with functional ankle instability (FAI) and with a matched control group. Peroneal latency and EMD were measured from 21 patients with unilateral FAI and 21 controls. Latencies were collected during a random inversion perturbat...
متن کاملEccentric plantar-flexor torque deficits in participants with functional ankle instability.
CONTEXT Inversion ankle sprains can lead to a chronic condition called functional ankle instability (FAI). Limited research has been reported regarding isokinetic measures for the plantar flexors and dorsiflexors of the ankle. OBJECTIVE To examine the isokinetic eccentric torque measures of the ankle musculature in participants with stable ankles and participants with functionally unstable an...
متن کاملDifferences between mechanically stable and unstable chronic ankle instability subgroups when examined by arthrometer and FAAM-G
BACKGROUND The objective measurement of the mechanical component and its role in chronic ankle instability is still a matter of scientific debate. We analyzed known group and diagnostic validity of our ankle arthrometer. Additionally, functional aspects of chronic ankle instability were evaluated in relation to anterior talar drawer. METHODS By manual stress testing, 41 functionally unstable ...
