The way that everyone walks is quite distinctive and almost no one walks the same way. There are plenty of unique major as well as subtle minor variants. These variances can assist to identify individuals on CCTV video footage as a part of forensic investigations and also valuable in gait studies to look into clinical conditions. There are now experts in the investigation of gait for the forensic identification. As well as that there are now some really advanced equipment and techniques for the clinical gait analysis. Both the forensic and clinical gait analyses focus on what it is that causes us to be unique in the manner which we walk and to measure those variances.
One of these variations is what is known as an abductory twist. This is often observed in clinical gait analyses as it may have consequences for the treatment of biomechanical issues. When we walk, as the rearfoot comes of the floor, the heel normally comes up straight. However, in a group of people just as the heel comes up off the floor there could be an abrupt movement of the heel medially or towards the other foot. Often it is only noticeable to those who are proficient in looking for it or on a video clip if the video is slowed down. There are several possible reasons for this. One is overpronation of the foot, which is a rolling of the ankle inwards and a collapse of the arch of the foot. Another possible cause is a functional hallux limitus which is a issue with the big toe joint not working properly. There is certainly some controversy if this is indeed a clinical issue or not. The question on how to fix an abdutory twist is oftewn asked. This is because many think about this as a sign of the problem instead of an actual issue. They consider that treatment needs to be directed at the reason why rather than the abductory twist. The existence or lack of an abductory twist would likely also be part of the forensic examination.
