An interventional study of MERITest in Healthy Adult Participants and Anterior Cruciate Ligament (ACL), sponsored by Clinique du Sport, Bordeaux Mérignac. Not yet recruiting at 1 site in France. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-10-21.

Anterior cruciate ligament (ACL) reconstruction is frequently associated with persistent biomechanical impairments despite clinically satisfactory recovery. The MERItest® is a standardized biomechanical assessment battery designed to evaluate movement strategies, muscle strength, and neuromuscular control during functional tasks. However, the clinical interpretation of these assessments is currently limited by the lack of normative data collected using a standardized protocol.
This single-center, prospective interventional trial involving minimal risk, aims to establish a biomechanical reference database of healthy volunteers based on measurements obtained during the MERItest® assessment.
The development of this normative database will enhance the interpretation of biomechanical outcomes in patients following ACL reconstruction by enabling direct comparison with a healthy reference population assessed under identical conditions.
Clinique du Sport, Bordeaux Mérignac is the lead sponsor of 11 studies on the registry; 11 are open to participants now.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Healthy volunteers will undergo the MERItest® during a single visit lasting approximately one hour. The assessment will be conducted by an experienced movement biomechanics specialist. Reflective markers (Qualisys Sports Marker Set - Functional Assessment) will then be placed on both lower limbs at the hip, knee, and ankle levels. These markers enable the collection of biomechanical data in the sagittal, frontal, and transverse planes, as well as side-to-side comparisons. Biomechanical assessment is performed using a combination of reflective markers, three-dimensional optoelectronic motion-capture cameras, and force and pressure platforms.
