Electric zaps to tongue could reveal best way to stop snoring

This study tests how different frequencies of electrical stimulation affect tongue muscles in 28 adults at high risk for sleep apnea. During a single visit, participants receive five different stimulation frequencies in random order. Researchers measure changes in tongue muscle thickness, length, and strength using ultrasound and a pressure device, along with discomfort levels. The goal is to find which frequency works best for future treatments.
