The viscoelastic properties of mucus have been described together with the methods which can be used to evaluate such a rheologically complex system. Methods which do not take into account the viscoelastic nature of mucus have been criticized and it is concluded that only creep or oscillatory tests yield significant correlations with mucociliary clearance rates.
