Efficacy of physiotherapy treatment in term newborns who have difficulty breastfeeding

INTERVENTION: The day after birth, the newborns and the mother will be evaluated using the Hazelbaker, Lach and VAS scales: based on the score obtained, it is checked whether there are difficulties in breastfeeding and, therefore, it is optimal to participate in the study. You will be randomly (randomly) assigned to one of two study groups. The intervention group will begin the Physiotherapy treatment based on the "Lip Out" method prior to hospital discharge. This method consists of specifically addressing the function of breastfeeding in terms of the seal that is made between the baby's mouth and the mother's breast. Oral motor dysfunctions that may be related to ankyloglossia (difficulty in tongue mobility due to a short and/or restrictive frenulum and also due to other alterations) that generate an incorrect sucking pattern will be addressed. The treatment will be carried out both during suction and at the moment of grasping. What is intended is to rela Xtensions that may be related to compensatory structures that make it difficult for the tongue to perform a correct function when sucking. Specifically, the posture of the mother at the time of breastfeeding the baby will be corrected, the accessory muscles of the mouth (orbicularis oculi, masseter muscles) will be relaxed and digital longitudinal stretching of the frenulum. Before hospital discharge, these exercises will be taught to the parents and an exhaustive follow‐up will be carried out for one month. The frequency of the sessions will be one hour a week during the first month of life (4 sessions of one hour in total). This follow‐up of the baby will be carried out until the first month of life. After this month of treatment, it will be evaluated again with the same scales to check whether or not there a CONDITION: Ankyloglossia; ; Ankyloglossia Musculoskeletal ‐ Other muscular and skeletal disorders Physical Medicine / Rehabilitation ‐ Physiotherapy PRIMARY OUTCOME: Hazelbaker scale to assess both the structure and function of the infant's tongue. This instrument is made up of items related to function (lateralization, elevation, width and length extension, cupping, peristalsis and spring of the tongue) and appearance. Each item will be scored from 0 (does not do it) to 2 (does it adequately), with an intermediate score of 1 (does not fully complete that item). If the function score is 14, regardless of appearance, no intervention is necessary. If the function score is 11, Physiotherapy treatment is recommended. Finally, if the score is less than 11, the function is considered impaired, so it is necessary to treat as soon as possible.[Before the intervention and one month after the beginning of the intervention.] Lach scale to assess breastfeeding. The following items will be assessed from 0 (null value) to 2 (maximum value), with an intermediate score of 1 (mean value): attachment, swallowing, type of breast and positioning of the baby at the breast. The maximum score will be 10, which means that there would be no risk of early weaning. If the score is less than 9, it indicates the need for support and monitoring of breastfeeding by professionals.[Before the intervention and one month after the beginning of the intervention.] Visual Analog Scale to check the pain experienced by the mother when breastfeeding. The mother will be instructed to mark her perception of pain with an X, considering 0 (null value) and 10 (maximum value).[Before the intervention and one month after the beginning of the intervention] SECONDARY OUTCOME: NIL[NIL] INCLUSION CRITERIA: 1. Term newborns (between 37 and 41 weeks of gestation). 2. Both men and women will be selected. 3. Both normal delivery and cesarean section. 4. Infants who have a low score on the initial assessment scale and, therefore, a problem in breastfeeding. 5. The parents of the babies must authorize their participation in the clinical trial, as well as subjecting the baby to low‐intervention physiotherapy treatment, signing said authorization in the Informed Consent.
