About

The goal of this observational study is to characterize the standardized stimulation parameter for noninvasive, transcutaneous, repetitive phrenic nerve electrical stimulation.

The main questions it aims to answer are:

• Is the phrenic nerve repetitive electrical stimulation test feasible for use as non-invasive transcutaneous electrical stimulation?
• What is the most optimal stimulation parameters for repetitive phrenic nerve electrical stimulation in healthy adult populations in terms of effective and safe activation of diaphragm?

Enrollment: 12 patients

Sex: All

Ages: 19 to 39 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Koreans who speak Korean as their mother tongue, aged 19 or older and younger than 40.
