OBJECTIVE To compare the effect of foot orthotics and rehabilitation exercises by assessing balancing ability and joint proprioception in athletes who have chronic ankle instability. METHODS Forty-one athletes who visited hospitals due to chronic ankle instability were randomly assigned to two groups. One group had ankle rehabilitation exercises while the other group had the same rehabilitati...

PURPOSE To determine if functional performance deficits are present in athletes with functional ankle instability (FAI) compared to healthy athletes using various functional performance tests. METHODS Sixty two athletes (mean age-21.7±1.8years; height-168.2±9.1cm; weight-63.8±11.0kg) participated in this case control study. Athletes were divided into two groups: athletes with FAI (FAI group, ...

[Purpose] Functional instability leads to a delay in the muscle reaction time and weakness of the peroneal muscles. The present study examined the effects of transcutaneous electrical nerve stimulation during balance exercise on patients with functional instability of the ankles, including the ability to land after jumping at the center of foot pressure. [Subjects] The subjects were seven males...

BACKGROUND The assessment of outcomes from the patient's perspective becomes more recognized in health care. Also in patients with chronic ankle instability, the degree of present impairments, disabilities and participation problems should be documented from the perspective of the patient. The decision about which patient-assessed instrument is most appropriate for clinical practice should be b...

Ankle sprain is one of the most commonly damaged lower extremities. More than 70% of people with ankle sprain experience chronic ankle instability. However, some people are well adapted to this damage (Coper people) and do not suffer from chronic ankle instability. The aim of this study was to compare EMG activity of the selected involved muscles in balance control strategies in athletes with c...

Background Gait has been generally viewed as a largely automated motor task, requiring minimal higher-level cognitive input. Increasing evidence, however, suggest that attention demanding cognitive tasks to disturb gait [1,2]. Movement variability may influence joint stability and increase the risk of “giving way” at the ankle in individuals with functional ankle instability (FAI)[3]. The purpo...
