A gait analysis is an assessment technique often used by health professionals to investigate the way that their clients walk or run. The goal of it is to evaluate if the gait is resulting in any conditions that they could be having and also to help plan any treatments which might be needed to modify the gait to help with those concerns. It is simply a matter of viewing someone walk, however highly complex gear and also mathematical assessment may be done. At one end of the selection will just be a visual assessment of the way that a person walks, but the issue with that is that many events of the running cycle happen so rapidly for the eyes to view properly. The are numerous programs available today for smartphone's to record the way that someone is running or walking and then slow the frames per second recorded on replay to perform a much more thorough analysis. Along at the other end of the range will be the sophisticated 3D assessment which is done with lots of trackers placed on the body and the use of a number of digital cameras that a computer subsequently transforms into a 3D replay of the walking.
There are more methods of examining the gait including making use of systems that measure muscle activity or pressures under the foot. These different methods works extremely well with all the above methods to provide a complete review of the gait of a person. Which system is used and exactly how in-depth the analysis is completed will be dependent on the type of the clinical condition which the patient has and just how complex it is and how complicated that the intervention must be. Research facilities likewise use various methods for research plus they often make use of equipment on the more complicated end of the solutions.
One of many important concerns is the difference between a 2 dimensional (2D) and a 3 dimensional (3D) evaluation. A 2D gait analysis is less expensive, but a 3D analysis can provide more details. A 2D gait analysis primarily typically investigates motion in a single plane or path and is comparable to taking a look at a photo. It is typically done with just one single camera. A 3D analysis examines motion in all directions, therefore makes use of multiple digital cameras and relies on considerable processing assets to combine all the data from the multiple cameras.
Another important decision is the use of a treadmill machine. A treadmill ensures that the client may be evaluated in one location at the exact same consistent pace on a number of occasions. An overground examination causes it to be more challenging to control for the velocity, particularly on future days. The other issue is that you will find numerous variations between the gait on a treadmill versus a gait overground, so it will not be a true portrayal of how an individual walks or runs.
Most of the challenges around gait analysis, especially 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 episode the hosts spoke with Chris regarding the alternatives that clinicians could use in their day-to-day clinical practice.
