How do people go about gait analysis in their clinical settings? Do you have analysis software, use a mobile phone or 3D lab? What assessments or validated tools do you use alongside the gait assessment itself?
Would love to hear what you recommend or find useful!
I'm curious too - there are many 2D machine learning style apps on the market, many of them free (including our own version on the resources page of researchworks.academy). No doubt 3D is more accurate but 2D is getting very usable these days as the machine learning algorithms are tracking human bodies and joints fairly well.
The benefits?
2D is fast - no calibration needed (though 2d planes are recommended for best results) and is mobile.
Downsides?
3D is still more accurate and there are more complex forms of analysis possible due to X, Y and Z co-ordinates in the mix.
I'm a computer science guy, so I think that this technology will only get better. It's already much better than eye-balling it (see the research by Professor Bhooma Aravamuthan, a previous ResearchWorks guest!) and the portability of this type of analysis is great. Not only that but occlusion is less of a problem as the markers do not need to be visible to the camera and interpolation is done naturally. Spatial tracking is still an issue but perhaps in the future some sort of specific (camera) hardware with specific visual ground markers may well provide even more exceptional result. Ground markers would give you specific ground plane tracking and measurements.
