The question then has to be, how far down the list to go before the "return on investment" in terms of better patient outcomes is not worth it?

This means that whatever system you use, it has to give a good return on that potential to change the intervention. A good gait analysis "method" or "system" has to have the potential to change the intervention, otherwise it was a waste of your time, patient $'s and probably unethical. There is no data on linking the nature of the gait analysis to better outcomes, nor are there any standards for 'best practice'Īs I keep challenging people to think: Does the information you are deriving from doing this have the potential to change the intervention that you choose to use. doi: 10.1016/j.jphys.2014.11.014.Everyone is going to have their preferences and biases!

The ICC was good for the hip, knee and ankle angles registered with Kinovea ® during the initial contact of walking for both observers (intra-rater reliability) and higher for the agreement between observers (inter-rater reliability). The Bland-Altman plots showed that the magnitude of disagreement was approximately ±5° for intra-rater reliability, ☒.5° for inter-rater reliability and around ☒.5° to ±5° for Kinovea ® versus Vicon ®.

The ICC for the inter-rater reliability was >0.90 for the hip, the knee and the ankle joints. The intra-rater reliability showed a good correlation for the hip, the knee and the ankle joints (Intraclass Correlation Coefficient, ICC > 0.85) for both observers. The motion data were recorded using the VICON Motion System ® and digital video cameras. All participants were examined twice with a one-week interval between the two appointments. Fifty healthy subjects participated in this study. The purpose of this study was to evaluate the inter- and intra-rater reliability of Kinovea ® and the agreement with a three-dimensional motion system for detecting the joint angles of the hip, knee and ankle during the initial contact phase of walking.

In order to reduce the costs of three-dimensional motion capture systems, new low-cost methods of motion analysis have been developed. Gait analysis is necessary to diagnose movement disorders.
