skdh.gait_old.AutocovarianceSymmetryV

class skdh.gait_old.AutocovarianceSymmetryV

The absolute difference between stride and step regularity for the vertical axis. It quantifies the level of symmetry between the stride and step regularity and provide an overall endpoint of symmetry for the gait bout

Methods

predict(fs, leg_length, gait, gait_aux)

Predict the bout level gait endpoint

Notes

If the minimum gait window time is less than 4.5 seconds, there may be issues with this endpoint for those with slow gait (those with stride lengths approaching the minimum gait window time).
