The way that everyone walks is incredibly distinctive and hardly any one does it exactly the same way. There are so many different major as well as subtle minor variations. These variations can assist to recognize individuals on CCTV video clips as a part of forensic investigations and also valuable in gait studies to investigate clinical conditions. There are now authorities in the investigation of gait for the forensic identification. As well as that there are now some very innovative gear 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 way which we walk and to evaluate those variants.
One of those varieties is what is known as an abductory twist. This is commonly seen in clinical gait analyses because it will have implications for dealing with biomechanical problems. When we walk, as the hindfoot comes of the ground, the heel should comes up straight. However, in a some people just as the rearfoot comes up off the floor there might be a sudden motion of the heel medially or towards the opposite foot. Often it is only visible to those who are familiar with looking for it or on a video clip if 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. An additional probable reason is a functional hallux limitus which is a problem with the big toe joint not functioning correctly. There is certainly some controversy if this is indeed a clinical problem or not. This is because many consider this as a symptom of the problem rather than a real condition. They consider that treatment ought to be aimed at the reason why rather than the abductory twist. The existence or lack of an abductory twist would most likely also be part of the forensic inspection.
