Education and Exercise for Patients With Longstanding Hip and Groin Pain

Longstanding hip and groin pain (LHGP) is a common and debilitating problem in young to middle aged individuals. These patients often get referred to orthopedic departments. Consensus statements on the management of these patients commonly recommend a physical therapist-led intervention as the first line intervention. However, the optimal content and delivery of this intervention is currently unknown. In this study we will compare the effectiveness of usual care (unstructured physical therapist-led intervention) to a semi-structured, progressive individualized physical therapist-led intervention on hip-related quality of life in people with longstanding hip and groin pain referred to an orthopedic department.

Adductor Endurance Test: Validity and Reliability

Groin and hip injuries are common in team sports-especially soccer, rugby, and ice hockey-and frequently affect male and young athletes. About 14% of all sports injuries involve the groin and hip region, with most related to the adductor muscles. These injuries often increase during congested match periods and may result in athletes missing 1 to 6.9 weeks of training or competition, extending up to 14 weeks when surgery is required. Weakness in the adductor muscles is a key risk factor for groin injuries, and current assessments primarily measure maximal strength using tools such as squeeze tests, sphygmomanometers, or dynamometers. However, muscle endurance-critical because many injuries occur under fatigue-has not been adequately studied, and no validated endurance tests for the hip adductors exist. This study aims to evaluate the validity and reliability of a newly developed hip adductor endurance test for monitoring endurance strength in professional soccer players.

Comparison of the Effect of Copenhagen Adduction Exercises Performed at Different Load-intensity

The aim of our study is to compare the effects of the Copenhagen adduction exercise, performed at different loading intensities, on hip muscle strength development, performance, flexibility, and delayed onset muscle soreness. The study will include active taekwondo athletes between the ages of 12-18. Athletes will be randomly divided into two groups: a low-intensity Copenhagen Adduction exercise group and a high-intensity Copenhagen Adduction exercise group. Athletes in both the low-intensity and high-intensity exercise groups will perform the exercise for 8 weeks in addition to their regular training program. At the beginning of the study and at the 4th, 8th, and 16th weeks, assessments will be conducted for hip abductor and adductor eccentric and isometric muscle strength, flexibility of the hip adductors, level of delayed muscle soreness, single-leg jump test, and timed lateral hop tests. The outcome of our study will determine how much improvement is achieved in hip muscle strength and lower extremity physical fitness parameters during and after the application of the Copenhagen adduction exercise at different loading intensities.
