What is an abductory twist?

The way in which everyone walks is incredibly unique and hardly any one walks the same way. There are plenty of different major as well as slight minor variants. These variants might help to identify people on CCTV video clips as part of forensic investigations and also useful in gait studies to examine clinical problems. There are now industry experts in the investigation of gait for the forensic recognition. As well as that there are now some really innovative gear and methods for the clinical gait analysis. Both forensic and clinical gait analyses give attention to just what causes us to be distinctive in the manner that we walk and to measure those variants.

One of these varieties is what is referred to as an abductory twist. This is commonly seen in clinical gait analyses since it does have implications for dealing with biomechanical problems. When we walk, as the hindfoot lifts of the ground, the hindfoot normally comes up vertically. However, in a group of people just as the heel comes up off the floor there may be an abrupt movement of the heel medially or towards the opposite foot. Often it is only noticeable to those who are experienced with looking for it or on a video 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 flattening of the arch of the foot. Another possible reason is a functional hallux limitus that is a problem with the big toe joint not functioning properly. There is some debate if this is actually a clinical issue or not. This happens because many think about this as a symptom of the problem instead of a real issue. They believe that therapy should really be aimed towards the main reason rather than the abductory twist. The presence or lack of an abductory twist would probably also be part of the forensic examination.
