About this study

The overall goal of this project is to reduce the risk for anterior cruciate ligament injuries by designing a targeted intervention that will alter the known kinematic and kinetic risk factors associated with ACL injuries.

Read the detailed description

This study will address the following specific aims: 1) To optimize a wearable, targeted, active training feedback device to reduce the risk of ACL injury among healthy subjects by inducing patterns of movement that alter the known kinematic and kinetic risk factors associated with ACL injuries. 2) To evaluate the efficacy of the active device and determine if the device reduces the risk of ACL injury among healthy subjects by effectively inducing patterns of movement that alter the known kinematic and kinetic risk factors associated with ACL injuries.

What participants receive

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

  • Activity Training with FeedbackDevice

    The feedback system consisted of three small inertial measurement units affixed on the chest, thigh, and shank segment respectively. These units were connected to a computer that recorded the signal from the inertial sensors at 240 Hz during the jump task. Using custom software, the knee flexion angle, trunk lean, and coronal thigh angular velocity were calculated immediately after the subject completed the jump trial. A projector was used to display the results of the jump analysis. It took less than 10 minutes to place this system on a subject and less than five seconds to analyze a jump.

Activity Training with FeedbackExperimentalSubject is tested prior to training and retested with feedback training designed to modify the mechanics of landing during jumping and running activities
Receives: Device: Activity Training with Feedback

What is being measured

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

  1. Knee Flexion Angle and Trunk Flexion Angle After Activity Training With Feedback

    Knee flexion angle describes the angle between the tibia and femur during the activity. Trunk flexion is the angle between the shoulders and the hips during the activity.

    Measured: 1 day

Secondary outcomes (1)
  1. Thigh Coronal Angular Velocity After Feedback Training

    How fast the thigh is moving relative to the tibia during the activity, measured in degrees/second.

    Measured: 1 day

Questions about this trial

What is this clinical trial studying?

A study testing Activity Training with Feedback in people with Athletic Injuries and Sprains and Strains, run by Stanford University at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

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 21 Apr 2017. 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 United States. 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?

Yes. Results are posted in the registry (first posted 21 Apr 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Knee Flexion Angle and Trunk Flexion Angle After Activity Training With Feedback (time frame: 1 day). 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 21 Apr 2017.
