简要总结
The ankle joint is often affected by injuries, especially lateral sprains, often leading to chronic instability. Joint mobilization techniques seem to influence the sense of joint positioning. The objective of the study is to compare mobilization techniques in the balance of athletes with chronic ankle instability. A randomized clinical trial with participants allocated in three groups: Talocrural manipulation, mobilization with movement and placebo will be assessed in their primary endpoints and secondary balance and dorsiflexion range of motion respectively.
详细描述
Biodex Balance System: The unipodal stability protocol was used in the anteroposterior and laterolateral directions. The test lasts for 20 seconds with five levels of instability, with level six being more stable and level two more unstable. The participant performed an adaptation test with the system and subsequently assessed the performance of the balance in three tests in each limb between each 10-second test. This will be instructed about the positioning during its evaluation, being oriented to keep the gaze in the previous direction; Hands on waist; Contralateral knee flexed at 90º, foot positioning is referenced in degrees on the platform as anthropometric information provided on the participant. At the end, the results of the anteroposterior and lateral-lateral directions and the general index were collected.
Weight Bearing Lunge Test (WBLT): The WBLT consisting of the use of a tape measure has no soil in which the participant will support or be evaluated so that the first finger touches On the tape and its distance to a reference wall for tape measurement. Required that the participant performs ankle dorsiflexion in CCF with the purpose of approaching the knee in the wall avoiding to remove the heel of the ground, that is on a marking.
Y test: To evaluate the dynamic balance and reach of lower limbs will be used The test balance consisting of the evaluation of the participant's performance during the movements of anterior, posteromedial and posterolateral angle with the value measured in centimeters with metric tapes In Direction.
The protocol performed six replicates for adaptation and one final repeat that is considered as a result of the test. For an earlier point, the reference point used is not support for a fixed reference point for the intersection of the conditions and for two other directions used. It is necessary that the participant be the same as the member farthest from the starting point without touching the tape. At the end of the seventh repetition is measured or value and considered the test result.
Intervention: Participants are divided into three groups: Thrust Group in open kinetic chain; MWM group in closed kinetic chain and control group with placebo intervention. Allocation in one of the groups will be randomized by lot.
