Hammock theory [sup] has been a milestone in explaining the etiology of SUI, as introduced by Ulmsten, illustrating that dysfunction of pubourethral ligament and pubococcygeus
is the major pathological mechanism of SUI.

The delay velocity of contraction in type 1 fibres in a muscle, such as pubococcygeus
, which has 70% slow-twitch fibres, explains why contraction is initiated by only a small number of fast-twitch fibres.
