Trial summary

Preventing lower limb injuries is a key concern in sports and physical activities. Even though injury prevention programs and pre-season screening have improved recently, these injuries still happen often. New technology might help improve traditional screening methods. Read more about this study

About this study

Preventing lower limb injuries is a key concern in sports and physical activities. Even though injury prevention programs and pre-season screening have improved recently, these injuries still happen often. New technology might help improve traditional screening methods. The BlazePod® system offers a fresh, active way to assess function and train physical skills. This study aims to explore the link between the BlazePod® One-Leg Balance Activity (OLBA) test and the Y-Balance Test (YBT) in healthy young adults. Using kinematic analysis, we want to see if the OLBA test can serve as a preseason tool to predict ankle injuries. Participants will complete the YBT, the Weight-Bearing Lunge Test, and the OLBA test with the BlazePod® system, along with the Cumberland Ankle Instability Tool (CAIT) and a sociodemographic questionnaire. We will record all tests using the Vicon T20S 3D motion capture system and analyze the data with MOKKA software. We expect to find a significant positive correlation between the average taps in the BlazePod® test and the combined YBT score. These results could show that the OLBA test with BlazePod® is a useful way to assess ankle injury risk.

Read the detailed description

Prevention of lower limb injuries is a major concern in sports and physical activity. Although injury prevention programs and pre-season screening tests have improved in recent years, the incidence of lower limb injuries remains high. Recent technological advances may complement traditional screening methods in identifying injury risk. The BlazePod® system offers an innovative, dynamic approach to functional assessment and physical skills training. The main objective of this study is to examine the relationship between the BlazePod® One-Leg Balance Activity (OLBA) test and the Y-Balance Test (YBT) in healthy young adults, using kinematic analysis to determine whether the OLBA test can be used as a preseason screening tool to predict ankle injuries. Participants will perform the YBT, the Weight-Bearing Lunge Test, and the OLBA test using the BlazePod® system and will complete the Cumberland Ankle Instability Tool (CAIT) and a sociodemographic questionnaire. All functional tests will be recorded using the Vicon T20S 3D motion capture system and analyzed with MOKKA software. We expect the results to show a statistically significant, positive correlation between the average number of taps in the BlazePod® test and the composite YBT score. We expect that these findings will suggest that the OLBA test using BlazePod® may be a useful tool for assessing ankle injury risk.

What participants receive

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

Study groups in NCT07505537
Study groupRoleWhat they receive
Ankle Range of MotionThe weight-bearing lunge test will be executed using kinematic analysis to assess ankle range of motion.
Dynamic BalanceThe Y-Balance Test will be executed to assess dynamic balance, namely, the reach distance of the lower limb obtained in the 3 reach directions, normalised with the lower leg length of the participant.
One Leg Balance Activity - OLBA TestThe one-leg balance activity will be executed with the Blazepod reflex training system, where the participant has to tap the pod that lights up during 60 seconds as fast as possible without losing balance.

What is being measured

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

  1. One Leg Balance Activity with the Blazepod

    The One-Leg Balance Activity will be assessed using the BlazePod® system to quantify the number of taps a participant can perform within 60 seconds while maintaining balance. During the test, pods illuminate in an alternating sequence, and participants are required to respond by tapping each light as quickly as possible without losing postural stability.

    Measured: From enrollment to the end of treatment at 1 week.

Secondary outcomes (2)
  1. Dynamic Balance

    The participant will execute the Y-Balance Test to assess dynamic balance. The composite score of the 3 reach distances will be used for analysis.

    Measured: From enrollment to the end of treatment at 1 week.

  2. Ankle dorsiflexion range of motion

    The ankle dorsiflexion range of motion will be assessed with the weight-bearing lunge test with kinematic analysis.

    Measured: From enrollment to the end of treatment at 1 week.

Questions about this trial

What is this clinical trial studying?

An observational study of Dynamic Balance and Range of Motion, Articular, run by Aveiro University at 1 site in Portugal.

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 1 inclusion and 1 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 28 Oct 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 Portugal. 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?

One Leg Balance Activity with the Blazepod (time frame: From enrollment to the end of treatment at 1 week.). 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 NCT07505537, which also lists 3 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?
