Hip Joint Disorders

Groin pain is a common and limiting condition in ice hockey players, often related to the high mechanical demands placed on the hip during skating. Repetitive movements involving hip flexion, abduction, and rotation may contribute to functional impairment and persistent symptoms. Recent clinical interest has focused on the relationship between the iliopsoas muscle and the anterior hip capsule, as their close anatomical and functional interaction may play a role in the development of hip-related groin pain. Percutaneous needle electrolysis (PNE) is a minimally invasive, ultrasound-guided technique used to promote tissue remodeling and pain reduction in musculoskeletal conditions. However, its application to the anterior hip capsule has not yet been investigated. This pilot experimental study aims to evaluate the effects of three sessions of PNE applied to the anterior hip capsule in male ice hockey players with groin pain. The main hypothesis is that this intervention may improve hip function by reducing pain and enhancing mobility and muscle strength. Outcomes include hip flexor strength, hip flexion range of motion, FADIR test results, and patient-reported outcomes measured with the HAGOS questionnaire. Assessments will be performed before and after the intervention, as well as at a 4-week follow-up.
