In both groups there was a reach restriction obtained in the SEBT execution promoted by the stabilization of these two types of external ankle stabilizers. However, in healthy individuals, ankle stabilizers should be used cautiously since in these cases a reduction in functional performance can really occur. The assessed athlete rested for 15 seconds between each trial. In general, our results showed two important findings: Archives of Gerontology and Geriatrics 42, The selected athletes were specialized in one of the five game volleyball positions as follow:
In both groups there was a reach restriction obtained in the SEBT execution promoted by the stabilization of these two types of external ankle stabilizers. Based on an a priori analysis, we adopted a potency of 0. Prophylactic ankle bracing versus taping effects on functional performance in female basketball players. This is an open-access article distributed under the terms of the Creative Commons Attribution License. The influence of orthoses on the proprioception of the ankle joint. The effect on neuromuscular stability, performance, multi-joint coordination and proprioception of barefoot, taping or preventative bracing. Clinical Biomechanics 17, The dominance found in the limbs was predominantly the right
Correlations among multiples measures of functional and mechanical instability in subjects with chronic ankle instability. In the DL, these differences were more evident in the directions: Various instruments and tests Functional Reach Test, force plate, isokinetic dynamometer, figure-ofhop, side hop, up-down-hop, single hop, triple hop test, etc.
Previous studies showed the limited effect of orthosis on dynamic stability Cordova et al. Clinical Biomechanics 19, Journal of Athletic Training 43, They found no significant difference between these two types of stabilizers, but claimed that both play an important role in preventing or rehabilitating ankle injuries.
Corroborating the results of this study, Ozer, Senbursa, Baltaci, and Hayran evaluated the effects of bracing and banding on functional balance, jumping performance, coordination and proprioception. In this situation, the limb is free to carry out the task. Revista Brasileira de Medicina do Esporte 15, Efficacy of the star excursion balance tests in detecting reach deficits in subjects with chronic ankle instability.
Clinical Biomechanics 17, The placebo effect of ankle taping on ankle instability. Journal of Strength and Condition Research, 27, estabbilizador Seventeen female volleyball players Archives of Gerontology and Geriatrics 42, The test execution for each type of external support happened on separate days, with hour intervals between them.
The distance reduction reached by the athletes in esatbilizador SEBT in the A, AL, L and PL directions, possibly, in virtue of the restricted dorsiflexion, inversion and eversion movements, promoted ankle stabilization.
Bristh Journal of Sports Medicine 31, In this way, individuals with mechanical instability, along with ligament laxity, certainly have some postural deficit.
Supporting this hypothesis, Sawkins, Refshauge, Kilbreath, and Raymond claim that ligament injuries cause tears in joint nerve fibers and a reduction of sensory input of the mechanoreceptors. The sample size was confirmed to be sufficient to provide This preliminary analysis of tornozel statistical power was conducted to reduce the type II error probability, and to determine the minimal number of subjects necessary for this investigation.
Conclusion The results of the study allow concluding that the external tested supports orthosis and functional bandaging affected similarly the ankle stabilization, regardless the analyzed lower limb.
Additionally, each athlete performed three practice trials for each limb aig all eight directions in order to familiarize themselves with the task and the procedure. Based on an a priori analysis, we adopted a potency of 0. A systematic review on the effectiveness of external ankle supports in the prevention of inversion ankle sprains among elite and recreational players. Measurement in Physical Education and Exercise Science 7, Callaghanin a literature review about the effects of various ankle supports on swelling, stability, ROM, proprioception, muscular function, walking and performance tests, observed that the use of rigid and non-rigid orthosis on athletes who are not seriously injured significantly reduces ankle movement, especially the inversion.
April 11, ; Accepted: Immediately after, the examiner always recorded the greatest distance in centimeters along the line from ccast center of the grid until the touch point of the foot Figure 2 reached by the volunteer. On the other hand, the majority of studies did not show significant effects establizador the external supports on the subjects’ performance. Some studies analyzing effects of orthosis and bandages on ankle stabilization generated discussions about whether these types of external ankle stabilizers interfere or not with the functional performance of an athlete without a history of injuries.
Active Ankle and AircastMckean, Bell, and Burnham verified that the tested supports caused functional damage. The multiple comparison Tukey post hoc test showed a significant difference between the groups: In a study that analyzed performance in some basketball movements, using some types of external supports Swede-O-Universal. For the test execution, the starting position was a single-leg stance on the lower limb under assessment. The Foot 19, How to cite this article. The identification of the line could vary according to the supporting limb assessed because the anatomical reference became the opposite lower limb ex: Journal of Athletic Training 42, The volunteer was instructed to try to reach the farthest distance possible on the chosen line and touch it with the distal end of the foot, as smoothly as possible, in order to prevent excessive weight transfer to the other foot, tornoaelo body stability and returning to the starting position.
The influence of the external ankle support on the dynamic balance in volleyball athletes
The selected athletes were specialized in one of the five game volleyball positions as follow: Furthermore, they should have more than 1 year of training and practice at least 3 times a week. The influence of orthoses on the proprioception of the ankle joint.
Each of the eight lines was measured with a metric tape and the examiner made smaller demarcations, each 1-centimeter, and larger ones each 5 centimeters, to facilitate visualization of the distance reached during the execution of the test and identified Olmsted et al. Prophylactic ankle braces tlrnozelo Star Excursion Balance measures in tonrozelo volunteers.
To Hubbade, Kramer, Denegar, and Hetelrecurring sprains cause postural damage to ligaments, thus decreasing the sensations related to muscular strength, movement and joint position.
In both groups there was a reach restriction obtained in the SEBT execution promoted by the stabilization of these two types of external ankle stabilizers. The sample was selected for convenience, satisfying the following criteria for inclusion: In general, there were no relevant reach differences found between the young subjects’ limbs, utilizing the SEBT. However, more studies on the true effectiveness of these implements are necessary for the proprioceptive activation dynamic balance of healthy subjects, to clarify the action of possible physiological and biomechanical mechanisms in specific activities of each sport, making the selection process of preventative measures for athletes clear.
