Regard to gait speed in advance analysis

[Wisavaporn Niamsang]

I would like to ask if OpenCap is possible to display walking gait speed on advance gait analysis because on the previous time I could see the results of gait speed, but now I can't see them. I'm not sure, I'm do something wrong or not.

Thank you very much, I really appreciate your hard work.

You should see the gait speed on the overground analysis but not on the treadmill analysis (we assume you know the speed of the treadmill there and do not want to add confusion but displaying a potentially slightly different speed), best, antoine

Actually, I would like to compare the gait speed that I recorded from treadmill and OpenCap. As you know, I know the actual speed from treadmill already but some time I would like to set the treadmill in self pace which is not fixed the speed. And from the previous time, I got the gait speed from OpenCap, and I saw that is pretty accurate with the real value. Therefore, I would like to bring gait speed data to report in my research project. So, if it possible to bring gait speed result in advance analysis on treadmill again.

Thank you very much

Interesting use case, I will think about this. You can also run the analysis locally and get the gait speed: https://github.com/stanfordnmbl/opencap ... nalysis.py

Thank you very much for helpful guidance. However, I have other question regarding the gait pattern, How can I know where is the initial contact in each gait cycle because I would like to get 100% of gait cycle since initial contact to terminal swing. That's why I would like to know the even during patient walk.

Thank you very much

Hey, if you run the analysis locally you can call get _gait_events() https://github.com/stanfordnmbl/opencap ... #L134-L136
