Testing the Reliability of Kinovea Video Analysis Software in Measuring Knee and Hip Angles During Sit-to-Stand Tasks

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.
