The popularity of running as a sport and recreational activity has risen up remarkably in the past few years. Key words: kinematics, 2D motion analysis, running, knee and hip angles, validity, reliability The ICC values (intra-rater reliability) for the hip and knee were 0.998 and 0.990 respectively whereas ICC values (inter-rater reliability) of 0.996 and 0.978 were computed for the hip and knee respectively.Ĭonclusion: The strong validity and excellent inter- and intra-rater reliability results establish a concrete foundation for use of GaitON- a 2D motion analysis system as a tool for evaluating the running gait of a patient in a clinical setup. Results: The angles quantified using GaitON were significantly correlated with the angles quantified in Kinovea with r = 0.997 p = 0.01 for the hip and r = 0.982 p = 0.01 for the knee. The intra-rater reliability, inter-rater reliability, the limits of agreement (LOA) in the Bland-Altman plot were also determined. Two blinded raters quantified joint angles on video using GaitON and Kinovea software. Methods: 21 healthy male recreational runners were recorded using a clinical 2D video setup during over-ground running. Objective:To investigate the convergent validity, inter- and intra-rater reliability of a 2-D motion analysis system (GaitON) for quantification of hip and knee kinematics at initial contact during running.
USING YOUR CAMERA ON KINOVEA SOFTWARE
Under these circumstances, use of motion analysis software with inbuilt running gait analysis protocols help to improve the reliability of data. Observational methods of assessing gait are largely dependent on clinicians’ ability to quantify and analyze the kinematic data in a reliable manner. 2D motion analysis systems are being widely used at a clinical level for quantification of kinematic parameters during running gait analysis.
Introduction: Analysis of running gait is necessary for prevention of hip and knee injuries.
