Condition: Accessory Muscle

Study Type: Observational

Sponsor: National Taiwan University Hospital

Study Description

Brief

Whether minimizing sternocleidomastoid (SCM) activation in supine position would increase diaphragm activation during loaded inspiratory muscle tests remains to be determined. Therefore, the purpose is to exam diaphragm and SCM activation during loaded inspiratory muscle tests in sitting and supine position in healthy adults.

Detailed

Inspiratory muscle training usually performed in the upright sitting position. In healthy individuals, sternocleidomastoid (SCM) is rarely recruited during tidal breathing, but previous studies have demonstrated SCM activation during loaded inspiratory muscle tests in upright sitting position. Whether minimizing SCM activation in supine position would increase diaphragm activation during loaded inspiratory muscle tests remains to be determined. Therefore, the purpose is to exam diaphragm and SCM activation during loaded inspiratory muscle tests in sitting and supine position in healthy adults.
