    Summary
    This summary is machine-generated.

    Increasing task difficulty, including cognitive demands, slowed gait termination time (GTT) and reaction time (RT) in young adults. These findings suggest more conservative gait strategies with increased complexity.

    Area of Science:

    • Biomechanics
    • Sports Rehabilitation
    • Cognitive Neuroscience

    Background:

    • Gait termination time (GTT) is a fall predictor in older adults.
    • GTT has not been studied in sport rehabilitation.
    • Concurrent cognitive tasks can assess complex gait in clinical populations.

    Purpose of the Study:

    • Compare planned vs. unplanned gait termination.
    • Evaluate the impact of concurrent cognitive tasks.
    • Analyze effects on reaction time (RT), gait velocity, and GTT.

    Main Methods:

    • Cross-sectional laboratory study.
    • Twenty young adults participated.
    • Gait termination trials (planned/unplanned) with/without cognitive tasks were performed on an instrumented mat.

    Main Results:

    • Dual-task conditions slowed gait velocity compared to single-task.
    • Cognitive tasks significantly increased RT and slowed normalized GTT.
    • Gait velocity was slowest during unplanned termination with a cognitive task.

    Conclusions:

    • Increased task difficulty led to more conservative gait and slower RT, normalized GTT, and gait velocity.
    • Further research is needed to determine clinical significance in athletic injuries.
