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.

Inclusion Criteria:

• 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.
