Sixty-one preterm newborns of 32-35 weeks' gestational age were recruited from the neonatal intensive care unit of the Chung Shan Medical University Hospital and randomly assigned to one of two groups: the experimental group (n = 31) or the control group (n = 30). Both groups received the same medical care, but the experimental group was exposed to ELF-EMFs until discharge.
Body weight gain is crucial for preterm newborns, especially those with a low birth weight. Owing to their noninvasive, noncontact, and non-pharmaceutical properties, extremely low frequency electromagnetic fields (ELF-EMFs) are a promising medium of alternative and complementary therapy.
