Effectivity of neuromuscular electrical stimulation and oral sensorimotor stimulation as therapeutic interventions for pediatric dysphagia: A comparative study of swallowing outcomes

Abstract

Background

Pediatric dysphagia poses risks to feeding safety, nutrition, and overall health, especially in those with developmental or neurological disorders. While various treatments exist, including therapeutic, medical, and surgical options, oral sensorimotor stimulation (OSMS) and neuromuscular electrical stimulation (NMES) are commonly used non-invasive interventions. However, their relative effectiveness remains uncertain, with limited evidence on their advantages in managing specific types of dysphagia.

Objective

This prospective cohort study aimed to compare the effectiveness of NMES and OSMS in managing pediatric dysphagia.

Methods

This study recruited pediatric dysphagia patients for a two-month rehabilitation program, with either NMES or OSMS with pre- and post-intervention evaluations using video-fluoroscopic swallow studies, Modified Barium Swallow Impairment Profile (MBSImP) scores, and the 8-point Penetration-Aspiration Scale (PAS).

Results

A total of 26 children participated in the study. NMES significantly reduced MBSImP scores in both oral and pharyngeal impairments, and PAS. OSMS showed significant improvement in MBSImP scores, particularly in oral impairment.

Conclusions

The study suggests NMES benefits oropharyngeal dysphagia and reduces penetration and aspiration, while OSMS is effective for improving oral dysphagia.
