You aren't still using 2D gait analysis...are you?
You aren't still using 2D gait analysis...are you?  - blog post image
2D gait analysis just isn't good enough anymore.  You wouldn't use ancient technology in a phone anymore (remember flip phones?), so why should your health and fitness be any different?

Research has repeatedly shown that ONLY three dimensional gait analysis assessments are accurate enough to detect the small movement patterns that might cause an injury. Although there are a select few people in the world who likely don't need it, because they are just that good...Unless your name is Irene Davis, then read on.  

Here are some of the reasons why 3D is better than 2D:

Seeing is believing - but it doesn't make it anymore accurate. 

Our minds are easily deceived - and are even better at playing tricks. We admit that an experienced gait analysis clinician would be able to identify large movements, such as those in the sagittal plane (your knees bending and straightening). However, what you are seeing, isn't necessarily the cause of what is taking place. For example, a collapse of the ankle inwards - or you may have heard being referred to as pronation (which is actually forefoot abduction, rearfoot eversion, and dorsiflexion) may be just that. However, the CAUSE of the collapse isn't clear. If you attempt to prevent this movement, by using an insole or stability shoe, when the source is actually coming from the hip, what do you think this is going to achieve? The foot is either going to continue to try and move too far, or because it is being stopped, it will transfer the load somewhere else. Either way the problem isn't solved. 

Subjective & Perspective...

Most 2D gait analysis systems require the gait analysis technician to 'analyse' the video by drawing lines on it. These systems are of course slightly more advanced than drawing on Microsoft Paint, but there is still a large margin of error at risk depending on the persons experience, training, and perspective. Also to note, if the view of the 2D camera is ever so slightly on an angle, your view and therefore your results are already inaccurate. 

Transverse? Whats that?

Imagine there was a camera positioned right over top of you when you were running. It would pick up all the finite rotation and twisting movements happening as you move. This is what is referred to as the 'transverse' plane of movement. It is the hardest to see by eye. But not if you have 3D gait analysis. Run3D gait analysis can see rotations of your pelvis, your hips, knees, and ankles. 

Run3D gait analysis uses infrared cameras and reflective markers attached to joint lines to measure your biomehcanics in all three dimensions. Not only can we calculate angles and give you exact amounts of movement, we can compare left and right sides, as well as to our normative uninjured database. Still not satisfied? Lets say you came in for an assessment in January with an injury. You could come in again in June  and we could compare your two different assessments to see what has changed. Yes, we know. Its pretty cool.

"But I'm too busy, it will take to long"

It really doesn't. With our new advanced technology we can do the gait analysis in minutes. The thing that normally takes the longest is answering all your questions! Also, you'd be singing a different tune if you were injured. OR, if i told you this would help you find the source of a problem faster. It takes away the guessing game for overuse injuries. Id say the slight investment of time is worth it, wouldn't you? 

Get with the times. Get a Run3D gait analysis assessment.
