Brief summary: Grater trochanteric pain syndrome is a hip related pathology that causes lateral hip pain and lack of strength in abductor muscles such as the gluteus medius, which hinders functional activities and daily life, such as standing, walking, sleeping on the affected side... Lack of strength and eccentric control of the gluteus medius may be related to the apparition of myofascial trigger points that are susceptible to treatment with dry needling.

In this study, two groups of patients with greater trochanteric pain syndrome will be treated with dry needling, some of them with real dry needling, and others with sham dry needling. Ultrasound will be used to assess whether real dry needling in the pelvitrochanteric musculature improves the potential contraction of the gluteus medius, in relation to a baseline measurement and to sham dry needling.

This study is a randomised clinical trial protocol, pilot study, so there will be no previous references for the sample of both study groups. 3 dry needling interventions will be performed in 3 consecutive weeks, leaving 1 week between each intervention. Data will be collected for the variables to be investigated (potential contraction, pain, function, strength...) before the first intervention, after each intervention, 1 month after the last intervention and at 3 months.


Eligibility criteria: Inclusion Criteria:

* Lateral hip pain lasting more than 3 months.
* Greater trochanteric pain syndrome compatible with changes on MRI.
* Clinical examination correlation: one of the following tests must be positive: FADER test, FABER test, hip adduction (ADD) test in side-lying position (DL), isometric contraction test in the ADD position, or single-leg stance test for 30 seconds.
* Pain/sensitization upon palpation of the trochanter.

Exclusion Criteria:

* Radicular pain due to lumbar pathology.
* Osteoarthritis.
* Pelvic pathology that could refer pain to the hip.
* Needle phobia.
* Hip injection performed less than 6 months ago.
* Dry needling performed less than 1 month ago.
* Surgery or pathology of the lower limb that prevents single-leg support.
* Systemic diseases that could interfere with the pathological process.
