Ankle sprains are a common injury and those affected are at a risk of developing chronic ankle instability (CAI). Complications of an acute sprain include increased risk of re-injury and persistent disability; however, the exact link between ankle sprains and chronic instability has yet to be elucidated. The purpose of this study was to investigate neuromuscular control (including kinematics, k...

[Purpose] The purpose of this study was to investigate the effects of chronic ankle instability and induced mediolateral muscular fatigue of the ankle on competitive Taekwondo athletes during single-leg drop landing. [Subjects and Methods] Fourteen competitive taekwondo athletes with chronic ankle instability and 14 healthy adults participated, and they performed three single-leg drop landings ...

objectives: ankle foot orthoses (afos) are widely utilized to improve walking ability in hemiplegic patients. the present study aimed to evaluate the effect of rocker bar ankle foot orthosis (rafo) on functional mobility in post-stroke hemiplegic patients. methods: fifteen hemiplegic patients (men and women) who were at least 6-months poststroke and able to walk without an assistive device for ...

BACKGROUND Ankle instability is a costly public health concern because of the associated recurrent sprains. It is evident there are neuromuscular control deficits predisposing these individuals to their ankle "giving way." Individuals with a history of lateral ankle sprain, who did not develop instability, may hold the key to understanding proper neuromuscular control after injury. HYPOTHESES...

Background Functional ankle instability (FAI) has been reported to be associated with sensorimotor deficits which could result in impaired balance [1] and altered foot kinematics [2]. Textured insoles that increase plantar cutaneous afferent information may compensate for a deficit of sensory input in FAI, improving postural control and reduce the risk of injury. Also, a lateral plantar wedge w...

The purpose of this study was to compare vertical ground reaction forces (GRF) and electromyographic activity (EMG) from peroneus longus (PL), tibialis anterior (TA) and gastrocnemius lateralis (GL) of volleyball athletes with and without functional ankle instability (FI) during landing after a blocking maneuver. Synchronized EMG and GRF from 200ms prior to impact to 200ms after impact were acq...

Chronic ankle instability is a complex problem which often follows ankle sprain. This workshop will discuss the latest models of chronic ankle instability and give an overview of the latest research in the area. Assessment tools available in the clinic as well as the laboratory setting will be demonstrated in the workshop with the opportunity for participants to practice. Assessments covered wi...
