Surface electromyography in premature infants: a series of case reports and their methodological aspects

Area of Science:

• Neonatal Physiology
• Biomedical Engineering
• Clinical Nutrition

Background:

• Assessing the complex suckling mechanism in premature infants is crucial for their development and nutritional intake.
• Traditional methods may not fully capture the nuances of oral motor function during feeding in vulnerable neonates.
• Surface Electromyography (sEMG) offers a non-invasive approach to quantify muscle activity during suckling.

Observation:

• sEMG was utilized to analyze the masseter and buccinator muscle activation patterns in five premature infants.
• Infants were evaluated across various feeding modalities, including breastfeeding, cup-feeding, and bottle-feeding.
• Distinct electromyographic profiles were recorded for each feeding method.

Findings:

• Breastfeeding and cup-feeding demonstrated higher masseter muscle activity compared to bottle-feeding.
• Bottle-feeding was associated with reduced masseter and increased buccinator muscle activity.
• These findings suggest differential recruitment of oral musculature depending on the feeding method.

Implications:

• sEMG provides a valuable tool for objectively evaluating suckling efficacy in premature infants.
• Understanding muscle activity differences can inform tailored feeding strategies and interventions.
• This method may aid in identifying infants at risk for feeding difficulties and optimizing their nutritional support.
