Reliability of the Gyko Inertial Sensor System in Evaluating Jumping and Postural Stability Parameters in Healthy Adults

The Gyko inertial sensor system is a lightweight and portable device that applies protocols for assessing and monitoring joint function, muscle strength, jump, and postural stability parameters during the rehabilitation of a specific musculoskeletal region. Previous studies have evaluated the validity of Gyko in assessing vertical jump height in female sub-elite soccer players and its reliability in evaluating postural stability in healthy, non-athletic adults. However, the findings regarding both the validity and reliability of the device have been limited. Our aim in this study is to evaluate the reliability of the Gyko inertial sensor system, an affordable and accessible tool that facilitates the assessment and monitoring of jump and postural stability parameters in healthy adults. If the study confirms the reliability of the Gyko device in evaluating these parameters, it could be used by clinicians, therapists, researchers, and/or coaches as a targeted alternative to gold standard methods for assessing jump and postural stability parameters in healthy adults. Hypotheses: H0: The use of the Gyko inertial sensor system is not reliable for assessing jump and postural control parameters in healthy adults. H1: The use of the Gyko inertial sensor system is reliable for assessing jump performance in healthy adults. H2: The use of the Gyko inertial sensor system is reliable for assessing postural control in healthy adults.
