Effect of Dry Needling on Gluteus Medius Contraction in Greater Trochanteric Pain Syndrome: a Pilot RCT Protocol

Plain-language 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.
