The way that we all walk is very distinctive and virtually no one walks the same way. There are plenty of different major as well as slight minor variations. These variances can help to identify people on CCTV footage as a part of forensic investigations and also useful in gait studies to investigate clinical issues. There are now experts in the investigation of gait for the forensic recognition. 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 concentrate on just what causes us to be unique in the way which we walk and to quantify those variances.
One of those varieties is what is termed an abductory twist. This is often observed in clinical gait analyses because it can have consequences for managing biomechanical problems. When we walk, as the heel lifts of the floor, the heel should comes up straight. However, in a some people just as the rearfoot comes up off the floor there might be a rapid 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 when the video clip 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. An additional probable cause is a functional hallux limitus that is a issue with the big toe joint not working adequately. There is some controversy if this is indeed a clinical problem or not. This happens because many consider this as a symptom of the issue instead of a real condition. They believe that therapy should really be geared towards the reason why as opposed to the abductory twist. The existence or absence of an abductory twist would likely also be part of the forensic examination.
