Trial summary

During physical activities, the time available to produce a force is infinitely shorter than the time required to reach maximal muscle capacity. Previous studies have observed that the time elapsed between ground contact and ACL rupture is on average 50-60 ms, suggesting that this is the time window available for any… Read more about this study

About this study

Official title: Benefits of Ballistic Tests in the Decision to Return to Sport After the Ruptured Anterior Cruciate Ligament Surgery

During physical activities, the time available to produce a force is infinitely shorter than the time required to reach maximal muscle capacity.

Previous studies have observed that the time elapsed between ground contact and ACL rupture is on average 50-60 ms, suggesting that this is the time window available for any attempt at dynamic stabilization of the joint through muscle contraction.

Sports movements include ballistic movements, defined as very fast movements whose objective is to accelerate a moving mass as much as possible so that it reaches a high speed in a very short time. This is the case for vertical jumps, running and most movements performed in physical and sporting activities.

Thus; (1) isokinetic tests do not allow a rigorous analysis of the components related to the speed of the movement; (2) functional tests such as jumping, which only give a distance between one leg and the other, do not allow the calculation of precise and reproducible variables concerning the force and speed of the movement, in particular during the first milliseconds of the movement, and do not provide information on compensation phenomena. It is therefore interesting to use the ballistic tests developed to monitor the movements of athletes as a new possible indicator of the return to sport.

The main objective of this study is to evaluate the performance of ballistic tests in predicting failure to return to physical activity 24 months after ACL surgery.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • isokinetic testOther

    Bilateral strength will be measured using a Contrex ® dynamometer equipped with an exercise table. Each subject will perform isokinetic tests of the right and left knee extensors and flexors. Subjects will be stabilized by straps during testing and the joint rotation axis will be aligned with the input shaft of the dynamometer.

  • Ballistic testOther

    ballistic squat jumps performed in the supine position on a frictionless sled at a resistance between 0% of body weight (BW)

  • K-STARTS testOther

    The K-STARTS (Knee Health Athletic Return To Sport) test brings together a set of 7 tests validated in the scientific literature to assess the control and neuromuscular capacities of the lower limb when performing dynamic movements as well as apprehension when resuming activity.

    Test in 30 minutes with physical exercises and questionnaire.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Analysis of the kinetics of force waves produced at high speed during ballistic movement

    Analysis of the kinetics of force waves produced at high speed during a ballistic movement will make it possible to determine the ability to resume physical activity at a level similar to that before the rupture in the absence of injury (risk = 2.3 / no risk = 0.1).

    Failure to resume physical activity 24 months after ACL surgery is defined by the occurrence of one of the following events:

    • Graft rupture,
    • Contralateral ACL rupture,
    • Decrease of at least 2 points in the Tegner 24 months after cruciate ligament surgery compared to the Tegner before the rupture

    Measured: 24 Months

Secondary outcomes (2)
  1. Return to physical activity via isokinetic test

    Fitness to resume physical activity via isokinetic test will be determined by quadriceps torque values (>3.0 Nm/kg) and an LSI>90%.

    Measured: 24 Months

  2. Return to physical activity via the K-STARTS test

    Fitness to resume physical activity via the K-STARTS test will be determined by a total score ≥ 18 points and individual results of the tests comprising the K-START between 2 and 3.

    Measured: 24 Months

Questions about this trial

What is this clinical trial studying?

A study testing isokinetic test, Ballistic test and K-STARTS test in people with Anterior Cruciate Ligament Injuries and Anterior Cruciate Ligament Rupture, run by Almaviva Sante 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 6 inclusion and 6 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: opening soon, as of the sponsor's last update on 6 Dec 2024. 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 Dr Nicolas MORIN-SALVO, MD (+33 4.91.61.17.95, n.morin-salvo@live.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Analysis of the kinetics of force waves produced at high speed during ballistic movement (time frame: 24 Months). 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 6 Dec 2024.
