Validity and Reliability of Gait and Jump Parameters Measured by the iSen Device in Healthy Adults

This study aims to evaluate the validity and reliability of gait and jumping parameters measured with the iSen device in healthy adults. Gait analysis is a valuable tool for assessing general health, cognitive performance, quality of life, and mortality. It is commonly used by clinicians to assess functional limitations resulting from neurological or orthopedic conditions and to guide treatment plans. Traditional gait assessments primarily focus on walking speed, but additional parameters such as step length, step time, and gait symmetry are crucial for a comprehensive analysis.

The study will also assess vertical jump performance, which is a surrogate measure of explosive lower limb strength and is commonly used in sports performance and injury prediction. The iSen device, a wearable and affordable sensor, will be compared to the validated BTS G-Walk system to evaluate the accuracy and consistency of its measurements. Participants aged 18-35 with no history of musculoskeletal, neurological, or systemic conditions will be included.

The study will be conducted at Gazi University and Kırıkkale University, where participants will undergo assessments of gait and jump performance using both iSen and BTS G-Walk devices. A test-retest reliability protocol will be employed with a seven-day interval between measurements. The results will provide evidence on the suitability of the iSen device for reliable and valid gait and jump measurements in clinical settings
