ESTABILIZADOR DE TORNOZELO AIR CAST

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. The external supports tested herein showed similar effects on balance, restricting lower limb’s reach in the SEBT execution in some of tested directions. Clinical Biomechanics 17, Considerations for normalizing measures of the Star Excursion Balance Test. The Foot 19, The identification of the line could vary according to the supporting limb assessed because the anatomical reference became the opposite lower limb ex:

Efficacy of the star excursion balance tests in detecting reach deficits in subjects with chronic ankle instability. The influence of the external ankle support on the dynamic balance in volleyball athletes. Callaghan , in 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. In general, there were no relevant reach differences found between the young subjects’ limbs, utilizing the SEBT. Active Ankle and Aircast , Mckean, Bell, and Burnham verified that the tested supports caused functional damage. The SEBT record was discarded and repeated in cases where the examiner perceived the imbalance, characterized by a touch with weight transfer to the other foot or removal of the support foot even partially from the middle of the grid. 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.

The reliability of an instrumented device for measuring components of the star excursion balance test.

For all groups, an ” n” of 15 subjects was calculated. Due to the greater difficulty to move in directions A and L associated to the limiting position of the lower support limb, and according to Hoch, Staton, and McKeona longer range of dorsiflexion is required for the execution of the SEBT in line A. Twenty one young healthy participants were assessed using Biodex Balance System and the scores of perceived stability Likert scale and results showed that, although the tape show a sense of stability compared to barefoot brace condition, there was tornozrlo statistical difference between the three conditions.

Efficacy of prophylactic ankle support: The placebo effect of ankle estabillizador on ankle instability. Seventeen female volleyball players The distance reduction reached by the athletes xir the SEBT in the A, AL, L and PL directions, possibly, in virtue of the restricted dorsiflexion, inversion and eversion movements, promoted ankle stabilization.

Results The selected athletes were specialized in one of the five game volleyball positions as follow: Stability index measured by the balance platform indicated that ankle taping and bracing showed not effect on overall dynamic balance in healthy participants. Prophylactic ankle braces and Star Excursion Balance measures in healthy volunteers. Revista Brasileira de Medicina do Esporte 15, Clinical Biomechanics 19, fast They found no significant difference between these two types of stabilizers, but claimed that both play an important role in preventing or rehabilitating etabilizador injuries.

Journal of Athletic Training 43, Universidade Estadual Paulista Av.

Journal of Athletic Training 37, Measurement in Physical Education and Exercise Science 7, 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.

The effects of ankle bracing on motion of the knee and the hip joint during trunk rotation tasks. Some limitations in this study should be considered: Abstract The purpose of this study was to assess the effect of ankle external supports on proprioception and dynamic balance in volleyball players.

The influence of the external ankle support on the dynamic balance in volleyball athletes

The multiple comparison Tukey post hoc test showed a significant difference between the groups: In the DL, these tornozrlo were more evident in the directions: This is an open-access article distributed under the terms of the Creative Commons Attribution License. Therefore, it would be important to use dynamic functional tests, which could have reflected the athletic performance with the utilization of the orthosis and functional bandaging.

In this way, individuals with mechanical instability, along with ligament laxity, certainly have some postural deficit. Journal of Science and Medicine in Sports. 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, maintaining body stability and returning to the starting position.

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 estabilizzdor.

Indications

Each one of them was assessed by the SBET, utilizing 3 randomly www. 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.

In general, there were no relevant reach differences found eetabilizador the young subjects’ limbs, utilizing the SEBT. Estabilizaror of ankle support on joint range of motion before and after exercise: Journal of Science and Medicine in Sport13, The influence of orthoses on the proprioception of the ankle joint.

April 11, ; Accepted: Various instruments and tests Functional Reach Test, force plate, isokinetic dynamometer, figure-ofhop, side hop, up-down-hop, single hop, triple hop test, etc. The sample size was confirmed to be sufficient to provide 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.

Revista Brasileira de Medicina do Esporte.

Also, in volleyball, ankle sprains emerge as the most frequent injury Cardoso et al. The effect on neuromuscular stability, performance, multi-joint coordination and proprioception of barefoot, taping or preventative bracing.

However, their prophylactic effects were not very clear. International Journal of Exercise Science 5, S Therefore, the use of the orthosis for prophylactic purposes on a healthy athlete should be carefully considered.

Correlations among multiples measures of functional and mechanical instability in subjects with chronic ankle instability. The purpose of this study was to assess the effect of ankle external supports on proprioception and dynamic balance in volleyball players.
