A gait analysis is an evaluation technique commonly used by clinicians to evaluate the way that their patients run or walk. The objective of it is to assess if the gait is leading to any problems that they could be having and also to help plan any treatments which might be needed to change the gait to help with these concerns. It's simply a matter of observing a person walk, but highly state-of-the-art devices and statistical examination may be done. At one end of the spectrum will only be a visual examination of the method in which an individual walks or runs, however the challenge with this is the fact that many events of the running cycle happen so quickly for the eyes to view appropriately. The are many programs available these days for smartphones to video the way that a person is walking or running and then slow the frames per second recorded on replay to carry out a more in depth assessment. At the other end of the spectrum is the complicated 3D assessment which is carried out with many markers placed on the body and the use of numerous cameras which a computer then transforms into a 3D replay of the walking.
There are more options for assessing the gait which include making use of techniques that measure muscle activity or pressures underneath the feet. These alternative techniques works extremely well with the above systems to offer a complete breakdown of the gait of you. What technique is used and exactly how deep the evaluation is completed can be depending on the type of the clinical challenge which the client has and how challenging it is and just how sophisticated that the intervention is required to be. Research laboratories also use various methods for research plus they often use apparatus at the more sophisticated end of the solutions.
Among the important issues is the difference between a 2 dimensional (2D) and a 3 dimensional (3D) gait analysis. A 2D evaluation costs less, but a 3D examination gives you more details. A 2D gait analysis simply typically studies motion in a single plane or path and is analogous to looking at a photo. It is normally done with just one single camera. A 3D examination has a look at movement in all directions, therefore uses an array of cameras and relies on considerable calculating resources to combine all the data from the three video cameras.
One more important decision is the use of a treadmill. A treadmill means that the client may be analysed in one place at the identical consistent velocity on several times. An overground analysis can make it more difficult to control for the pace, particularly on following occasions. The other issue is that you will find quite a few adaptations between the running on a treadmill versus a gait overground, so it will not be a real representation of the way an individual runs or walks.
Many of the challenges around gait analysis, in particular the use of 2D and 3D in clinic has been reviewed with an expert, Chris Bishop in an episode of the podiatry livestream, PodChatLive. In the show the hosts talked with Chris about the choices that clinicians could use in their daily clinical work.
