Accumulative Effects of Talus Mobilization

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to verify the effect of anteroposterior talus mobilization on range of motion, pain, and functional capacity in participants with sub-acute and chronic ankle injuries.

Detailed Description
-----------------
The purpose of this study was to verify the acute effect (one session) and chronic (six sessions) and follow-up of the anteroposterior talus mobilization Maitland's grade III on range of motion, pain, and functional capacity in participants with sub-acute and chronic ankle injuries. Thirty eight volunteers subjects (male and female) participated of this study with minimum 18 and maximum 59 years old. The volunteers were allocated in two groups: experimental and control. The variables related to range of motion, pain and functional capacity were measured by biplane goniometer, Visual Analog Scale and Foot and Ankle Ability Measure respectively in four moments: 1- baseline; 2- after the first intervention; 3- after the sixth intervention (two weeks); 4- follow-up (one month). The experimental group received anteroposterior articular mobilization of the talus and the control group received manual contact.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: joint mobilization<br>Anteroposterior mobilization of the talus (Maitland mobilization grade III) | Other: joint mobilization<br>* The experimental group received joint mobilization (anteroposterior mobilization of the talus - Maitland grade III). During the mobilization cyclic movements were applied in an anteroposterior direction from the first tissue resistance barrier until the end of the accessory range of motion without any pain or discomfort. This mobilization maneuver was performed in 30-second duration sets with a 30-second interval between each set. The interventions lasted two weeks with three sessions each, completing six sessions.<br>|
| Placebo Comparator: manual contact<br> | Other: manual contact<br>* The placebo group received only manual contact. This maneuver was performed in 30-second duration sets with a 30-second interval between each set. The interventions lasted two weeks with three sessions each, completing six sessions.<br>|
