title: Assessment of sensorial oral stimulation in infants with suck feeding disabilities.
abstract: A non-randomized single blind study was undertaken to determine the clinical and physiological changes in suck feeding after sensorial oral stimulation, in fourteen patients age 9 to 210 days old with sucking alterations. Patients lacked at least one of the five oral reflexes, plus two or more abnormal sucking sings or at least one abnormal sucking sign, plus two or more abnormal oral reflexes. Oral sensorial therapy was performed thrice daily for five days. The number of absent oral reflexes, number of abnormal sucking signs, volume of milk for nursing and sucking rate, were registered. Differences of medians were tested using Freidman's test and differential of proportions using Cochran's Q test. After therapy, oral reflexes were recovered (2, 0-4 vs. 5,5-5, p = 0.0000, median rank of absence oral reflexes) and the number of abnormal sucking signs decreased (6,1-9 vs. 1, 0-4; p = 0.0000). There were statistically significant improvements in patients who had lost launch up nipple ability (p = 0.005), delay at the beginning of sucking (p = 0.0022), drawing of milk from the mouth (p = 0.0001), cyanosis (p = 0.0084), weaning (p = 0.0004) and prolonged sucking (p = 0.0038). Even in patients with moderate improvement, no statistical differences were observed in nipple rooting (p = 0.09) and coughing (p = 0.09). No changes were observed in patients who had cried (p = 0.31) and spitted (p = 0.51) during feeding. At the end of therapy, volumes of consumed milk were increased at each feeding (10 ml, 0-40 vs. 50 ml, 25-60; p = 0.0001). Sucking rates also increased (22 sucks/minute, 10-35 vs. 40.5, 35-48; p = 0.0044). Oral sensorial and motor stimulation normalise oral motor reflexes, diminish the clinical abnormal sucking signs and increase milk volumes ingested for nursing.
