About this study
This clinical study investigates whether contralateral training (exercising the non-immobilized arm) can help preserve muscle strength and mass in patients recovering from shoulder surgery with elbow immobilization. Immobilization is often necessary to prevent further injury, but it can lead to significant muscle loss and reduced strength, delaying recovery and increasing healthcare costs. Recent studies suggest that training the non-immobilized arm may help maintain muscle function in the immobilized arm, particularly when using eccentric exercises (where muscles lengthen under tension). This study aims to compare the effects of eccentric and concentric (shortening) contralateral training versus standard care (no training) in patients undergoing shoulder surgery.
The study involves 4 visits: pre-surgery assessments, a 4-6 weeks' immobilization period with or without training, and follow-ups at the end of immobilization, 6 weeks' post-immobilization, and 17 weeks' post-immobilization. Participants will be randomly assigned to one of three groups: a control group receiving standard care, a group performing eccentric training, or a group performing concentric training. Muscle strength, mass, and function will be measured using tests such as isometric strength, ultrasound imaging, and functional scores.
The hypothesis is that eccentric contralateral training will better preserve neuromuscular function and muscle mass in the immobilized arm compared to both standard care and concentric training. This could lead to faster recovery and improved outcomes for patients. The study will provide valuable insights into optimizing rehabilitation strategies for patients recovering from shoulder surgery.
Read the detailed description
The study is structured into four visits:
- Inclusion Visit (V0): During the pre-surgical consultation, patients are informed about the study and provided with an information sheet and consent form.
- Pre-Surgery Visit (V1, PRE): Conducted within 7 days before surgery, this visit includes baseline measurements on both arms (immobilized and non-immobilized). Assessments include:
- Isometric maximal voluntary strength of elbow flexors and extensors using an isokinetic dynamometer.
- 1-RM (one-repetition maximum) for elbow flexors and extensors.
- Arm circumference at 5, 10, and 15 cm from the elbow crease.
- Anatomical cross-sectional area of arm muscles using ultrasound.
- Forearm circumference at 5 cm from the elbow crease.
- Handgrip strength (finger flexors).
- Functional scores: DASH (Disabilities of the Arm, Shoulder, and Hand), Constant-Murley, joint position sense (proprioception), and muscle stiffness.
- Following surgery, patients enter a 4-6 weeks' immobilization period, during which they are randomly assigned to one of three groups:
- Control Group (CTRL): Receives standard care, including rehabilitation sessions three times per week.
- Eccentric Training Group (EXC): Performs standard care plus eccentric training of the non-immobilized arm.
- Concentric Training Group (CON): Performs standard care plus concentric training of the non-immobilized arm.
The training protocol involves 3 sessions per week, separated by 24-48 hours. Each session includes 4-6 sets of 10 repetitions of elbow flexion/extension exercises on the non-immobilized arm at 60-90% of 1-RM, depending on the week. Eccentric or concentric actions are performed based on group assignment, with controlled contraction duration (4 seconds) using a metronome. Rest periods of 2 seconds between repetitions and 2 minutes between sets are provided.
- Follow-Up Visits:
- V2 (POST): At the end of immobilization, the same measurements as V1 are repeated
- V3 (POST + 6 weeks): Measurements are repeated again.
- V4 (POST + 17 weeks): Measurements are repeated again.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This clinical study investigates whether contralateral training (exercising the non-immobilized arm) can help preserve muscle strength and mass in patients recovering from shoulder surgery with elbow immobilization. Immobilization is often necessary to prevent further injury, but it can lead to significant muscle loss and reduced strength, delaying recovery and increasing healthcare costs. Recent studies suggest that training the non-immobilized arm may help maintain muscle function in the immobilized arm, particularly when using eccentric exercises (where muscles lengthen under tension). This study aims to compare the effects of eccentric and concentric (shortening) contralateral training versus standard care (no training) in patients undergoing shoulder surgery.
The study involves 4 visits: pre-surgery assessments, a 4-6 weeks' immobilization period with or without training, and follow-ups at the end of immobilization, 6 weeks' post-immobilization, and 17 weeks' post-immobilization. Participants will be randomly assigned to one of three groups: a control group receiving standard care, a group performing eccentric training, or a group performing concentric training. Muscle strength, mass, and function will be measured using tests such as isometric strength, ultrasound imaging, and functional scores.
The hypothesis is that eccentric contralateral training will better preserve neuromuscular function and muscle mass in the immobilized arm compared to both standard care and concentric training. This could lead to faster recovery and improved outcomes for patients. The study will provide valuable insights into optimizing rehabilitation strategies for patients recovering from shoulder surgery.

Questions about this trial
What is this clinical trial studying?
A study testing Eccentric training of the non-immobilized arm and Concentric training of the non-immobilized arm in people with Shoulder Surgery, run by Centre Hospitalier Intercommunal de Toulon La Seyne sur Mer at 1 site in France.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 9 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: looking for participants now, as of the sponsor's last update on 7 Jul 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 France. 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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Magali Cesana (04 83 77 20 60 ext. +33, magali.cesana@ch-toulon.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Isometric maximal voluntary strength of the immobilized arm (time frame: Preoperatively and at the end of the 4-6 weeks immobilization period). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 7 Jul 2026.
