Quintic Automatic Gait Report – The High-Speed Video Gait Analysis System for the Podiatrist…
In the same way knee flexion and ankle joint dorsiflexion etc can be measured from a sagittal view. The system is proving invaluable in patient education; never before have my patients truly understood what an orthosis can do. I can now play back clips of before and after treatment so that they can see the resultant reduction in frontal plane motion of the foot or a slowing of knee rotation.The use of the system in paediatrics has proved particularly beneficial: Parents are impressed to see the developmental changes between six monthly visits. It is very much more convincing to see the difference between the two images and measure them on screen than to try and explain that the genu valgum has reduced by 2cm! The child that won’t co-operate or sit still can be filmed during their consultation and pertinent measurements can be taken in stance. It is also useful to record such features as internal and external rotation for future visual comparison.
A new feature of Quintic software was to observe in a clinical setting the subtalar joint aixis, by using a 4 point calculation which measures the moving angle between two lines. In the case of the subtalar joint, the bisection of the calcaneum and of the tibia. The difficulty in this observation is the changing angle between the bisection and the camera, in comparison with a sagittal plane analyzing video (sagittal knee or ankle flexion-extension).
The new subtalar analysis function which is available with Quintic Biomechanics video analysis software allows the clinician to accurately and quickly identify and diagnose subtalar joint problems, while also enabling detailed observation and control of an intervention/treatment in an objective way. With many anatomical joints not having a fixed axis of rotation, Quintic’s new angular analysis method is a more accurate method of analysing body motion and is more accurate than fixing an artificial axis of rotation.
