The mothers will be distributed in two groups (lumbosacral massage) and control (routine maternity) and will be assessed before and after therapy, which corresponds to 30 minutes between 4-5 cm of cervical dilation.
The evaluation will be performed by numerical category scale, Diagram Location of Pain and Pain Questionnaire McGll (reduced form).
After delivery will apply a customer satisfaction questionnaire.
Aperçu de l'étude
Description détaillée
The pain in labor appears as a subjective experience, individual interaction involving a broad physiological, psychosocial and environmental influences, representing one of the main clinical signs of this phase.
Despite presenting an important biological function, is today well established the need for their relief, since its persistence is associated with harmful effects on mother and fetus.
Among the available non-pharmacological resources, we highlight the massage therapy that has shown positive effects in relieving pain and promoting the comfort of the mother.

Effectiveness of Massage Therapy in Pain Relief During Labor.
Délai: 30 minutes
|
The Visual Analogue Scale was used to assess the pain intensitiy after each procedure according to the study design.
The VAS is a scale composed by a straight line printed on a paper measuring 100 milimeters, where only the 0 (Zero) and the 100 (one hundred) points are marked.
The patient is then asked to mark this line accordingly to the intensity of the pain felt in that moment, considering 0 (Zero) to be no pain at all, and 100 (one hundred) to be the most unbearable pain ever suffered.
The researcher would measure the distance, in milimeters, from the 0 (Zero)mm to the point were the patient marked, wich was considered to be the intensity of the pain felt by the patient in that moment.
A reduction of 13mm or more in this scale is considered to be a significative pain reduction.
