Reliability of Kinovea Software for Measurement of Transtibial Amputee Knee Kinematics

February 23, 2025 updated by: Senay Cerezci Duygu, Saglik Bilimleri Universitesi

Reliability of Kinovea Software for Measurement of Transtibial Amputee Knee Angle During Walking

The primary aim of this study was to find the reliability of Kinovea software in measuring parameters associated with sagittal plane knee kinematics during gait in transtibial amputees. The secondary objective was to calculate the absolute reliability by calculating the Standard Error of Measurement (SEM), SEM% and Minimal Detectable Change at 95% confidence interval (MDC95). The SEM value represents the extent to which a score changes during the repetition of the measurement. The MDC is the minimum change in the measurement that is considered a true change in the measured activity that is not due to error.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Vİdeo Recording
Time Frame: From enrollment to the end of video record (10 minutes).

The gait of the individuals will be recorded to determine the sagittal plane knee angular values during walking:

Participants will be asked to wear comfortable clothing to avoid limitation of movement. Before recording any measurements, participants will be asked to walk a few laps around the test area to familiarize them with the procedure and the movements being measured. Video images of each participant will be acquired using a digital camera (Canon EOS600D) to capture the sagittal plane profile of the knee. The camera will be placed on a tripod at a height of 80 cm, 1.5 m away from the participants. The tripod will be placed on taped markers on the floor to maintain the same distance between the camera and the participants. All images will be transferred to a laptop and analyzed using Kinovea software, a free, open source software created for motion analysis (Kinovea, 0.8.15, http://www.kinovea.org/).
From enrollment to the end of video record (10 minutes).
