This study is a double-blinded randomized controlled trial focused on groin injury rehabilitation. It aims to explore the benefits of adding the Copenhagen Adductor Exercise (CAE) to standard physical therapy programs. The study will recruit participants from physical therapy outpatient clinics in the South region of Saudi Arabia. The importance of this research lies in its potential to enhance current rehabilitation practices for groin injuries, which could lead to improved recovery and reduced pain for affected individuals. Participants will be randomly assigned to either the intervention or control group. The intervention group will undergo a modified progressive Copenhagen adduction program along with their regular physical therapy for eight weeks. The control group will receive only the standard physical therapy rehabilitation program. An experienced physiotherapist, unaware of the study details, will perform all assessments at the beginning and end of the intervention. The primary outcomes to be measured are changes in eccentric hip adduction strength and hip joint range of motion from the baseline. These measurements will be taken using a portable hand-held dynamometer and a standard goniometer respectively.

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.

Design Details

30 patients to be enrolled

Total number of participants that the clinical trial aims to recruit.

Treatment Study

These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.

Eligibility

Researchers look for people who fit a certain description, called eligibility criteria: person's general health condition or prior treatments.

Criteria

Any sex

Biological sex of participants that are eligible to enroll.

From 18 to 40 Years

Range of ages for which participants are eligible to join.

Healthy volunteers not allowed

If individuals who are healthy and do not have the condition being studied can participate.

Criteria

5 inclusion criteria required to participate

Soccer players aged between 18 to 40 years.

They have groin pain or injury within two months during sports.

Pain or tenderness on palpation of adductors in clinical examination.

Pain on resisted hip adduction movement in clinical examination.

5 exclusion criteria prevent from participating

Groin pain or injury not involving the adductors on clinical examination.

They have any clinical finding indications of femoral or inguinal hernia.

Evidence of prostatitis, chronic urinary tract disease.

Evidence of hip joint osteoarthritis or hip joint disease.

Treatment Groups

Group I

Experimental

The CAE is a body-weight exercise that mainly works the groin and hip adductors. It has a significant eccentric component, meaning the muscles work while lengthening. The CAE is a simple isolated eccentric exercise that does not require special equipment. Due to the heaviness and the high dynamic demands of CAE, a modified progressive Copenhagen adduction (MPCA) program has been created. The MPCA exercise was adapted from the original CAE to lessen the risk of delayed onset muscle soreness (DOMS) and facilitate high participant compliance. An experienced physical therapist will include the MPCA in the usual rehabilitation program for eight weeks, twice weekly. Sessions will last between 30 and 120 minutes.

Group II

Active Comparator

The rehabilitation program will be an active exercise based on the available literature and considers the clinical experience in managing groin injuries. An experienced physical therapist will supervise the rehabilitation program for two sessions weekly for eight weeks, with difficulty and volume progressing incrementally. Sessions will last between 30 and 120 minutes.
