kinovea program for assessment of female student’s knee joint proprioception in closed kinetic chain: emphasis on validity and reliability

This study aimed to investigate the validity and reliability of kinovea software in assessing the position sense of knee joint. methods: 15 female students of physical education and sport science (20-25aged) participated at this study voluntarily. in this study, knee joint position sense was measured using photography (kinovea software) and goniometer methods and calculation of the reconstruction angle and reconstruction angle error methods at three different closed kinetic chain knee flexion angles of 120, 135, 150 degrees while open and closed-eye conditions. spss26 software and pearson correlation method was used for data analysis. the significance level was set at α= 0.05. the reliability of kinovea and goniometer measurements were assessed using test-retest method. also, the correlation between the kinovea and goniometer measurements were used for the assessment of validity of kinova software in evaluating knee joint position sense. results showed that kinovea software has high validity in assessing the knee joint proprioception in all three different knee flexion angles of 120, 135, 150 degrees and eyes open and closed conditions(p<0.05) and there were significant positive correlations between two methods under different conditions. also, both kinovea and goniometer methods had high repeatability (p<0.05). kinovea software has high validity and reliability in assessment of knee joint position sense. so, this software can be recommended as a valid, reliable, easy, efficient, and cost-effective method for assessing knee joint proprioception in sports and clinical settings.
