Abstract:
Introduction
Functional ankle instability has described as a feeling of giving way. Balance control deficit is one of the sensorimotor impairments observed in people with functional ankle instability that has been described to damage to the afferent receptors within the ligaments and joint capsule that affected during sprain. Foot orthosis can improve balance control via enhanced sensory afferent feedback of plantar surface of the feet and prevent inappropriate moment around the ankle joint. The purpose of this study was to examine the of effect lateral wedge and textured lateral wedge insole on static balance in people with functional ankle instability.Materials and
Methods
20 athletes(mean age: 25.57±4.77 years)with clinically diagnosed unilateral functional ankle instability were recruited. Measurments performed in three conditions by using a kistler force plate(Kistler instrument corp, Amherst, New York USA,version.5060). The mean center-of-pressure excursion and mean velocity in medial-lateral and anterior-posterior directions, area of 95% confidence circle and sway area were assessed as measures of standing balance. The results were statistically analyzed using the nonparametric Friedman test followed by Wilcoxon Signed Rank.Results
Foot orthoses resulted in decrease mean total and anterior-posterior COP excursion, %95 confidence circle area and increase mean medial-lateral COP excursion, mean COP velocity in medial-lateral direction and area sway, but these changes were not statistically significant.Conclusion
Foot orthoses had no significant effect on postural stability in patients with functional ankle instability.Keywords:
