About this study
Official title: Effect of Core Stability Training on Hip Adduction Abduction Strength Ratio in Young Gymnasts With Adductor Strain: A Randomized Controlled Trial
Adductor muscle strain is a common cause of groin pain in young athletes, particularly in gymnasts who frequently perform movements that require extreme hip flexibility and strength. Muscle imbalance around the hip joint and reduced core stability may increase the risk of adductor injuries.
This randomized clinical trial aims to investigate the effect of adding core stability training to a traditional physiotherapy rehabilitation program on the hip adduction-abduction strength ratio in young gymnasts with adductor muscle strain.
Read more
Thirty-six young gymnasts aged 7-10 years with Grade I or II adductor strain will be randomly assigned to two groups. Both groups will receive a traditional physiotherapy rehabilitation program for eight weeks, while the study group will also perform additional core stability exercises.
Outcomes will include hip adductor and abductor strength measured using a hand-held dynamometer, pain intensity assessed using the Visual Analog Scale (VAS), and hip and groin function evaluated using the Copenhagen Hip and Groin Outcome Score (HAGOS).
The findings of this study may help determine whether adding core stability training improves rehabilitation outcomes in young gymnasts with adductor muscle strain.
Read the detailed description
Adductor muscle strain is one of the most common causes of groin pain in athletes and is frequently reported in sports that involve rapid directional changes, high-impact landings, and extreme hip ranges of motion. Young gymnasts are particularly vulnerable to such injuries due to the repetitive mechanical loading placed on the hip and groin region during training and performance. Muscle imbalance around the hip joint, particularly an altered hip adduction to abduction (ADD:ABD) strength ratio, has been identified as a key intrinsic risk factor associated with groin injuries.
Core stability plays an essential role in maintaining lumbopelvic control and providing proximal stability for efficient movement of the lower extremities. Deficits in core stability may increase compensatory movements at the hip joint and contribute to excessive loading on the adductor muscles. Consequently, incorporating core stability exercises into rehabilitation programs may improve neuromuscular control and optimize hip muscle function.
The aim of this randomized clinical trial is to investigate the effect of adding core stability training to a traditional physiotherapy rehabilitation program on hip adduction-abduction strength ratio, pain intensity, and hip and groin function in young gymnasts diagnosed with adductor muscle strain.
Thirty-six young gymnasts aged 7-10 years with Grade I or Grade II adductor muscle strain will be randomly assigned to either a study group or a control group. Both groups will receive a traditional physiotherapy program three times per week for eight weeks. The study group will additionally perform a structured core stability training program.
Outcome measures will include hip adductor and abductor muscle strength assessed using a hand-held dynamometer, pain intensity measured using the Visual Analog Scale (VAS), and functional outcomes evaluated using the Copenhagen Hip and Groin Outcome Score (HAGOS). Assessments will be conducted before and after the intervention period.
The results of this study may contribute to improving rehabilitation strategies for young athletes with adductor-related groin injuries and may help determine whether core stability training provides additional benefits beyond traditional physiotherapy.

core stability training + traditional physio therapy for study groupOther
Also called core stability exercises
Core stability training (CST) was implemented to improve trunk control and lumbopelvic stability in young gymnasts with adductor muscle strain. The program was performed three times per week for eight consecutive weeks and was provided in addition to the traditional physiotherapy program. Each session included approximately 30 minutes of CST exercises focusing on neuromuscular control of the trunk and pelvis. The training protocol consisted of progressive exercises including abdominal hollowing, abdominal bracing, dissociation of the shoulder and pelvic girdles, cat-camel exercise, quadruped stance, front bridge, side bridge (both sides), and supine bridge. The program was delivered in three progressive phases with gradual increases in training difficulty to enhance trunk muscle activation, improve lumbopelvic stability, and optimize force transmission through the kinetic chain during lower limb movements.
traditional physiotherapy for control groupOther
Also called conventional physiotherapy
The traditional physiotherapy program was designed for the rehabilitation of adductor muscle strain and was conducted three times per week for eight weeks, with each session lasting approximately 70 minutes. The program included a 10-minute warm-up using a cycle ergometer followed by pain-free strengthening exercises targeting hip flexion, extension, abduction, and adduction performed in side-lying and standing positions. Isometric adductor strengthening exercises were performed in the supine position using a small roll placed between the knees or feet. Balance and proprioceptive training were incorporated using balance boards and functional tasks. Stretching exercises for the hamstrings, gluteal muscles, hip flexors, and iliotibial band were performed during the cool-down period. In addition, low-level laser therapy was applied for 10 minutes over the symptomatic adductor tendon insertion sites to reduce pain and local tenderness.

What is being measured
The primary outcome is the main question the study is designed to answer.
Hip Adduction-Abduction Strength Ratio (ADD:ABD ratio)
Hip adduction and abduction muscle strength were measured using a hand-held dynamometer, and the ratio between adduction and abduction strength was calculated to evaluate hip muscle balance.
Measured: Baseline and after 8 weeks of intervention.
Secondary outcomes (2)
pain intensity
Pain intensity related to adductor strain was assessed using the Visual Analog Scale (VAS), where higher scores indicate greater pain.
Measured: Baseline and after 8 weeks of intervention.
hip and groin function
Functional status was evaluated using the Hip and Groin Outcome Score (HAGOS), a questionnaire assessing symptoms, pain, daily activities, sport and recreation, participation in physical activities, and quality of life.
Measured: Baseline and after 8 weeks of intervention.

The sponsor lists 5 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 12 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Hip Adduction-Abduction Strength Ratio (ADD:ABD ratio) (time frame: Baseline and after 8 weeks of intervention.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07466134, which also lists 13 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Mar 2026.
