ABSTRACT

BACKGROUND: Myasthenia gravis (MG) is a rare and chronic autoimmune neuromuscular disease that causes weakness among skeletal muscles responsible for mobility and breathing. Individuals with MG who have difficulty breathing may need to schedule an emergent provider visit where a negative inspiratory force (NIF) measurement test is performed to measure respiratory strength.

PURPOSE: Examine the feasibility of individuals with MG to perform NIF respiratory function monitoring in the home setting and determine its impact on their perceived quality of life.

METHODS: This is a quantitative one-group pretest-posttest study of 30 individuals (18-75 years old) who carry the diagnosis of MG and have been stable with treatment for at least 30 days. Participants completed the Brunnsviken Brief Quality of Life Scale (BBQ-LS) and the System Usability Scale (SUS) prestudy. Participants were required to independently perform and record their NIF measurements twice daily for 14 days. After completing the 14 days, participants completed the BBQ-LS, SUS, and an end-of-study survey.

RESULTS: There was a significant difference in BBQ-LS scores at baseline (M = 62.97, SD = 17.84) and poststudy (M = 98.2, SD = 13.63) (t[29] = -5.39, p
