Intervention model description: Feasibility study
Primary purpose: TREATMENT

Brief summary: The purpose of this study is to investigate whether targeted progressive resistance training is safe and feasible for patients with external snapping hip. Dropout rates, adverse events and training adherence are investigated. The secondary purpose is to investigate whether it is possible through targeted progressive resistance training to improve participants' muscle strength, functional status and hip-related quality of life.

Detailed description: Snapping hip (coxa saltans) is a disorder where the hip tends to make an audible click-through movement, often but not necessarily associated with pain. A prevalence of 5-10% of the general population has been reported. Snapping hip is divided into three forms of snapping hip; intraarticular, internal and external snapping hip. External snapping hip (coxa saltans external) is the most common form, and patients may experience pain when the iliotibial band or anterior part of the gluteus maximus slides over the greater trochanter at femur. Patients with external snapping hip are typically between 15 and 40 years, and physically active.

Eligibility criteria: Inclusion Criteria:

* Diagnosed with Greater Trochanteric Pain Syndrome at the Orthopedic Surgery Department at Aarhus University Hospital in the period 2013-2015. In case of too few participants from this sample, we plan to include patients diagnosed during 2018
* Minimum 18 years old
* Able to read and understand Danish
* Have experienced jump/click from the outside of the hip associated with pain within the last 14 days
* Have a residence of a maximum of 55 km from Aarhus C
* The participants must not have participated in regular resistance training of the hip muscles for more than 1 day per week in the last 6 months leading up to the start of the intervention
* The participants must not have undergone a total hip replacement, a Periacetabular Osteotomy, a Z-plastic surgery or arthroscopy in the hip within 6 months before the start of the intervention or have a planned hip surgery during the intervention period
* The participants must not suffer from neurological, rheumatological, metabolic or respiratory diseases that will influence the effect of the intervention
* The participants must not have a planned vacation lasting more than 14 days during the intervention period, while not having the opportunity to extend the training period accordingly

Exclusion Criteria:

* BMI \>40
* No longer suffering from external snapping hip
* Pregnancy
