I am using a split-belt treadmill in my lab and am reading z-direction (vertical) forces from it. I use ML to find events such as heel strike and toe off based on where the forces cross a certain threshold.
The problem arises when the subject steps over the midline and on to the other belt, thus not allowing the force on that belt to return to near zero.
I was wondering if anyone had come up with a good solution in their ML code, or perhaps knows enough about this matter to think of one. I have used a couple of different methods, but none have proved to detect every event I am looking for.
Thank you in advance.
