About

The purpose of this study is to see if daily massage therapy will help premature infants respond to stress better, as well as improve their growth and neurobehavioral development.

Full description

Optimal postnatal growth and development is essential for the survival and long-term health of infants born premature, however, growth and developmental delays are common. Many factors contribute to poor postnatal growth and development including immature organ systems, stress due to illness and even routine care in the neonatal intensive care unit environment. Massage therapy is associated with decreased cortisol levels during stress in a variety of populations including premature infants. Massage has also been reported to improve postnatal weight gain in premature infants. Concerns about methodological quality, however, weaken the credibility of previous studies and prevent the integration of massage therapy into conventional medical practice. Therefore, we plan to study the interrelationship of the ANS and HPA axis in preterm infants to assess how developmental massage therapy (DMT) modulates physiologic stability and promotes postnatal growth by the following specific aims:

SPECIFIC AIM 1: We will determine ANS balance, measured by heart period variability, before, during, and after DMT.

SPECIFIC AIM 2: We will compare the relationships between ANS balance and HPA response before and after DMT.

SPECIFIC AIM 3: We will evaluate somatotrophic response in premature infants who receive DMT.

Infants will be stratified by gender and randomized to receive developmental massage therapy or SHAM control.

This study will also allow for post-discharge assessment of development. Infants will return to the hospital at term, 3months and 6 months for multiple measurements and developmental testing.

Enrollment: 46 patients

Sex: All

Ages: Under 14 days old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Premature infants born between 29 4/7 and 32 3/7 weeks gestation by physical exam at birth, and with birth weight, length and head circumference between the 5th and 95th percentiles for gestational age.

Exclusion criteria

• Intrauterine growth less than the 5th or greater than the 95th percentiles for gestational age, congenital anomalies, complex cardiac defects, severe CNS injury, hypothyroidism, inborn errors of metabolism, or inability to establish full enteral feeds by day of life 14.

Trial design

Primary purpose: Basic Science

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Double Blind

---

46 participants in 2 patient groups, including a placebo group

DMT group

Active Comparator group

Description:

These infants will receive tactile stimulation and developmental massage by a licensed therapist. This intervention will be done behind a screen in order to blind the therapy to NICU staff and parents.

Treatment:

Other: Developmental Massage Therapy

SHAM control

Placebo Comparator group

Description:

These infants will have no tactile stimulation or developmental massage done. The therapist will stand behind a screen but will not touch the infant. The screen will blind the NICU staff and parents to the study arm.

Treatment:

Other: no intervention
