Gluteus Medius Dry Needling and Ankle Instability

Study Overview
=================
Brief Summary
-----------------
Randomized clinical trial in individuals with chronic ankle instability. Main outcomes were as follows: pain intensity, pressure pain threshold, lower limb balance and range of motion. The sample will be divided in two groups: 1) dry needling at the gluteus medius trigger point (intervention). 2) dry needling 1,5 cm from the gluteus medius trigger point (control).

Detailed Description
-----------------
Inclusion criteria will be: individuals with chronic ankle instability, 20 to 50 years old. Exclusion criteria: any lower limb disease, fractures, infections, pregnancy, received any treatment in the previous 3 months. Initially, the base measurements were as follows: paint intensity, pressure pain threshold at the gluteus medius trigger point, ankle range of motion and balance of the lower limb. Once baseline measurements will be taken, the same evaluations will be performed at 4 weeks from the start.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Intervention group<br>Individuals for this group will be treat with a dry needling intervention at the gluteus medius trigger point. | Other: Dry needling<br>* For this intervention, the physiotherapist will be placed a needle in the gluteus medius trigger point from 8 to 15 times.<br>* Other names: Manual Therapy;|
| Active Comparator: Control group<br>Individuals for this group will be treat with a dry needling technique at 1,5 cm from the trigger point (not in the trigger point). | Other: Dry needling<br>* For this intervention, the physiotherapist will be placed a needle in the gluteus medius trigger point from 8 to 15 times.<br>* Other names: Manual Therapy;|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Pain intensity | Individuals reported the pain intensity with the Visual Analogue Scale (VAS scale). The minimum and maximum scores were 0 (no pain) 100 (the worst pain). There was no sub-scales. | 1 day | 
| Pain pressure threshold | Pain pressure threshold were recorded with a pressure algometer. Evaluator press the trigger point with the algometer until the patient feel pain. The outcome will be recorder and expressed in kg/cm2 | 1 day | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Range of motion | Assess the ankle range of motion with a goniometer. | 1 day | 
| Balance | Assess the lower limb balance with the star excursion balance test | 1 day |
