Resumo

Introduction: Despite the evaluation of technology in human movement evaluation, the high cost and specific training of these kind of technology are not feasible for clinical practice. An ideal videogrammetry system should be easy to use, low cost, with minimal equipment, and fast realization. Objective: This paper aims to determine if CvMob is a reliable tool for the evaluation of bidimensional human gait. Methods and materials: The sample was composed of 56 healthy individuals who were simultaneously filmed by CvMob and Vicon system cameras. Linear trajectories and angular measurements were compared to validate the CvMob system, and inter and intrarater findings of the same measurements were used to determine reliability. Results: A strong correlation (rs mean = 0.988) of the linear trajectories between systems and inter and intrarater analysis were found. According to the Bland-Altman method, the angles that had good agreement between systems were maximum flexion and extension of the knee and dorsiflexion range of motion and stride length. Conclusion: The CvMob is a reliable tool for analysis of linear motion and lengths in bidimensional evaluations of human gait. The angular measurements demonstrate high agreement for the knee joint; however, the hip and ankle measurements were limited by differences between systems.
