About this study
Official title: Reliability of Kinovea for Knee and Hip Angle Measurements During Sit-to-Stand
The purpose of this study is to evaluate the intra-observer and inter-observer reliability of the Kinovea video analysis software in measuring knee and hip angles during the sit-to-stand movement. Participants will perform sit-to-stand tasks while being video-recorded. The recorded movements will be analyzed using the Kinovea software to determine the consistency and reliability of joint angle measurements.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Healthy Adults | The study consists of a single group. This group will comprise healthy individuals who meet the predefined inclusion and exclusion criteria. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Hip Flexion
Participants will perform a sit-to-stand task using a standard chair while lower extremity movements are recorded with a camera. The recorded videos will be transferred to the Kinovea software for the measurement of hip joint angles. To facilitate angle calculation, anatomical landmarks including the greater trochanter, the longitudinal axis of the trunk, and the midpoint of the thigh will be marked on the participant's clothing. Hip joint angles will then be analyzed using the angle measurement tool available in the software. Measurements will be performed independently by three physiotherapists at one-week intervals.
Measured: At baseline (single video recording session)
Knee Flexion
Participants will perform a sit-to-stand task using a standard chair while lower extremity movements are recorded with a camera. The recorded videos will be transferred to the Kinovea software for knee joint angle analysis. To calculate knee joint angles, anatomical landmarks including the greater trochanter, lateral femoral condyle, and lateral malleolus will be marked on the participant's clothing. Knee joint angles will then be analyzed using the angle measurement tool within the software. Measurements will be performed independently by three physiotherapists at one-week intervals.
Measured: At baseline (single video recording session)

What does the primary outcome measure?
Hip Flexion (time frame: At baseline (single video recording session)). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
