First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study used ultrasound to measure how much the diaphragm thickens during a sniff in 60 healthy adults. The goal was to define a normal range for this measurement, which could help doctors spot diaphragm problems in the future. Participants were grouped by age and gender to see if these factors affect the results.
