The way that we all walk is very unique and hardly any one does it the same way. There are so many unique major as well as subtle minor variants. These variances may help to recognize people on CCTV footage as part of forensic investigations as well as being valuable in gait studies to examine clinical disorders. There are now professionals in the analysis of gait for the forensic identification. As well as that there are now some very advanced equipment and techniques for the clinical gait analysis. Both forensic and clinical gait analyses give attention to what it is that causes us to be one of a kind in the manner that we walk and to evaluate those varieties.
One of these variants is what is referred to as an abductory twist. This is often observed in clinical gait analyses as it does have consequences for dealing with biomechanical abnormalities. When we walk, as the heel lifts of the floor, the rearfoot should comes up vertically. However, in a some people just as the rearfoot comes of the floor there can be a sudden movement of the heel medially or towards the other foot. Often it is only apparent to those that are proficient in looking for it or on a video when the video is slowed down. There are a few possible causes of this. One is overpronation of the foot, which is a rolling of the ankle joint inwards and a flattening of the arch of the foot. Another possible reason is a functional hallux limitus that is a issue with the big toe joint not working properly. There is some discussion if this is indeed a clinical problem or not. This happens because many consider this as a sign of the issue instead of an actual condition. They consider that therapy ought to be aimed at the main reason instead of the abductory twist. The presence or lack of an abductory twist would definitely also be part of the forensic examination.
