Thanks for giving information.

I have an another query; as I am working with gait stability, I observed that many research papers are collecting data using some wearable sensors or camera (Vicon etc.) and through analyzing obtained data by some statistical approach gait stability is concluded. Some papers also used gait modeling approach to analyze stability.

But if we are getting necessary data from sensors (e.g. wearable and vision based) for stability analysis then what is the need gait modeling which is itself a computationally intensive procedure?
