The way that everyone walks is very unique and almost no one walks exactly the same way. There are numerous unique major as well as slight minor variations. These variants might help to identify individuals on CCTV video footage as a part of forensic investigations as well as being beneficial in gait studies to look into clinical problems. There are now specialists in the investigation of gait for the forensic recognition. As well as that there are now some very sophisticated equipment and methods for the clinical gait analysis. Both the forensic and clinical gait analyses give attention to just what causes us to be unique in the way that we walk and to quantify those distinctions.
One of those variations is what is generally known as an abductory twist. This is frequently observed in clinical gait analyses as it can have consequences for the treating of biomechanical problems. When we walk, as the heel lifts of the floor, the rearfoot normally comes up vertically. However, in a group of people just as the heel comes up off the floor there can be a sudden movement of the rearfoot medially or towards the opposite foot. Often it is only noticeable to those that are proficient in looking for it or on a video if the video is slowed down. There are several probable 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. An additional probable cause is a functional hallux limitus that is a issue with the big toe joint not functioning correctly. There is some discussion if this is indeed a clinical problem or not. This happens because many think about this as a sign of the problem rather than a real problem. They argue that therapy should really be aimed towards the main reason as opposed to the abductory twist. The presence or lack of an abductory twist would certainly also be part of the forensic analysis.
