Abnormal uterine action can be classified into two categories: over-efficient uterine action and inefficient uterine action. Over-efficient uterine action includes precipitate labor (lasting less than 3 hours) and excessive contraction and retraction (in the presence of obstruction). Inefficient uterine action includes hypotonic inertia and hypertonic inertia. Other types of abnormal uterine action include constriction (contraction) ring and cervical dystocia.
