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).
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.

For this intervention, the physiotherapist will be placed a needle in the gluteus medius trigger point from 8 to 15 times.

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.
Time frame: 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
Time frame: 1 day
Range of motion
Assess the ankle range of motion with a goniometer.
Time frame: 1 day
Balance
Assess the lower limb balance with the star excursion balance test
Time frame: 1 day
