Perineal rehabilitation is a therapy through movement 1. The oldest mention of this therapy occurred for the treatment of urinary incontinence, in the "Swedish Work"medical text published in 1861. In this article they did not describe the type of such exercises 2.
Perineal rehabilitation uses exercises for muscle strenghtening, based on the idea that reapeated voluntary movements provide increase in the muscular strenght 3.
The effects of perineal rehabilitation are based on the development, improvement, restauration and muscular coordination.
The strenght and ability that a muscle or muscular group has to develop tension that results in a maximum effort,dinamical as well as static, in relation to the resistance imposed on these muscles 4. The strenght of a normal muscle is measured by manual muscle exams, where the answer to the movement against gravity or maximum resistance is graduated. As a muscle contracts and the tension develops, a force is put into action. The amount of force produced by the muscle depends on a variety of biomechanical, physiological and neuromuscular factors 1.
