I am looking for a reliable algorithm to detect gait events in patients with moderate to severe gait impairments. Whereas some existing algorithms work satisfactorily in good to moderate walkers (e.g. Zeni-Algorithm for kinematic analysis), they are often prone to errors in patients with more pathological gait patterns. Force/pressure-based methods are considered the gold standard for automated gait detection, however, they are not really feasible during free overground walking.

Can anybody recommend an algorithm for robust detection of gait events during treadmill and overground walking in patients with severe gait pattern deviations?
