About this study

Official title: Validity, Reliability, and Clinical Correlates of Virtual Reality Adaptations of the 4-meter Walk Test, Five Times Sit-to-stand Test, and Timed up and go Test in Older Adults

Objective assessment of mobility, balance, and lower extremity function in older adults is of great importance in both clinical practice and scientific research. For this purpose, performance-based tests that can be administered in a short time, are easily repeatable, and have high clinical practicality are widely preferred. These tests provide valuable information about older adults' ability to perform activities of daily living, levels of functional independence, and risk of falls, thereby contributing significantly to both diagnostic processes and treatment planning.

One of these tests, the 4-Meter Walk Test (4MWT), is among the simplest and most reliable methods used to assess walking speed in older adults. Gait speed is considered a strong indicator of functional capacity and overall health status in older individuals and is also used as a critical parameter for predicting mortality, morbidity, hospitalization rates, and duration of independent living. Therefore, due to its short administration time, high repeatability, and clinical validity, the 4MWT has become one of the standard assessment tools in the field of geriatrics.

Another frequently used assessment tool, the Five-Times Sit-to-Stand Test (5xSTS), is based on measuring the time required for an individual to consecutively stand up from and sit down on a chair five times. This test is closely associated with lower extremity muscle strength, functional independence, and the ability to maintain activities of daily living. In addition, the 5xSTS test is an important clinical tool for identifying muscle weakness and mobility limitations in older adults with a history of falls. Owing to its short administration time, lack of requirement for specialized equipment, and ease of understanding, it is widely used in both clinical settings and field studies.

In addition, the Timed Up and Go (TUG) test is considered one of the gold standard methods for the assessment of functional mobility. The test is simple to administer: the time required for an individual to stand up from a chair, walk a specified distance, turn around, and return to sit down is measured. The TUG test not only assesses mobility but is also a reliable and valid method for predicting balance impairments and fall risk. Given that falls represent a major health concern in older adults, data obtained from the TUG test provide valuable guidance for both clinicians and researchers.

In recent years, virtual reality (VR)-based assessment methods have attracted increasing attention due to their potential to provide a safe, motivating, and standardized environment, particularly for older adults. In this study, the Meta Quest 3 virtual reality headset and controllers will be used to implement VR-based functional tests. The Meta Quest 3 device features a resolution of 2064 × 2208 pixels per eye, a maximum refresh rate of 120 Hz, and a six-degrees-of-freedom (6 DoF) inside-out tracking system. The device tracks participants' head and body movements in real time and accurately reflects them within the virtual environment. This system does not require external sensors and automatically provides positional tracking in the virtual space. Previous studies have demonstrated that VR applications can produce valid and reliable outcomes when used as digital adaptations of functional tests. However, the validity and reliability of VR adaptations of the 4MWT, 5xSTS, and TUG tests in older adults have not yet been systematically investigated.

The rationale of this study is to determine whether VR-based short performance tests can serve as a safer, more easily repeatable, and potentially more accessible alternative to conventional clinical assessments. The findings of this study are expected to provide important evidence supporting the use of VR technology in clinical practice for the assessment of mobility and balance in older adults.

What participants receive

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

  • Clinical AssessmentsOther

    Participants will perform virtual reality-based adaptations of the 4-Meter Walk Test, Five-Times Sit-to-Stand Test, and Timed Up and Go Test using an immersive virtual reality application developed for the Meta Quest 3 platform. The virtual environment digitally replicates the conventional test setups and protocols, and performance outcomes are automatically recorded by the system. Virtual reality-based assessments will be compared with conventional clinical tests and repeated to evaluate validity, reliability, and clinical correlates.

What is being measured

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

  1. 4-Meter Walk Test - Virtual Reality (4MWT-VR)

    This outcome measure will be used to assess gait speed using a virtual reality-based adaptation of the 4-Meter Walk Test. Walking speed will be automatically calculated by the system. Validity will be evaluated by comparison with the conventional 4-Meter Walk Test, and reliability will be assessed using repeated measurements performed 5-7 days apart.

    Measured: Baseline and 5-7 days

  2. Five-Times Sit-to-Stand Test - Virtual Reality (5xSTS-VR)

    This outcome measure will be used to assess lower extremity functional performance using a virtual reality-based adaptation of the Five-Times Sit-to-Stand Test. Test duration will be automatically recorded. Validity and reliability will be evaluated by comparison with the conventional test and repeated measurements.

    Measured: Baseline and 5-7 days

  3. Timed Up and Go Test - Virtual Reality (TUG-VR)

    This outcome measure will be used to assess functional mobility using a virtual reality-based adaptation of the Timed Up and Go test. Test completion time will be automatically recorded by the system. Validity and reliability will be examined through comparison with the conventional Timed Up and Go test and repeated measurements.

    Measured: Baseline and 5-7 days

Secondary outcomes (5)
  1. 4-Meter Walk Test - Conventional

    The conventional 4-Meter Walk Test will be administered to assess gait speed and will be used as a reference measure for concurrent validity analyses.

    Measured: Baseline

  2. Five-Times Sit-to-Stand Test - Conventional

    The conventional Five-Times Sit-to-Stand Test will be used to assess lower extremity muscle strength and functional mobility and will serve as a reference for validity analyses.

    Measured: Baseline

  3. Timed Up and Go Test - Conventional

    The conventional Timed Up and Go test will be administered to assess functional mobility and fall risk and will be used as a reference for concurrent validity analyses.

    Measured: Baseline

  4. Lower Extremity Muscle Strength

    Lower extremity muscle strength will be measured using standardized clinical methods and will be examined for its relationship with virtual reality-based performance test outcomes.

    Measured: Baseline

  5. Physical Activity Level (International Physical Activity Questionnaire - Short Form, IPAQ-SF)
