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.

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.

Inclusion Criteria:

• Individuals aged ≥18 years, practicing physical activity, and without recent complaints in the lower limbs or spine will be included.

Exclusion Criteria:

• Participants with federated sports practice, recent history of ankle sprain, surgery or musculoskeletal injury in the lower limb, as well as systemic pathologies affecting balance or neuromotor control will be excluded.

Active university students of both sexes, aged ≥18 years, that practice physical activity regularly and without recent complaints in the lower limbs or spine will be recruited for the study.

Individual participant data (IPD) will be shared upon reasonable request.
