Intra- and inter-rater reliability of maximum inspiratory pressure measured using a portable capsule-sensing pressure gauge device in healthy adults

摘要

BACKGROUND:Measurement of maximum inspiratory pressure is the most prevalent method used in clinical practice to assess the strength of the inspiratory muscles. Although there are many devices available for the assessment of inspiratory muscle strength, there is a dearth of literature describing the reliability of devices that can be used in clinical patient assessment. The capsule-sensing pressure gauge (CSPG-V) is a new tool that measures the strength of inspiratory muscles; it is easy to use, noninvasive, inexpensive and lightweight.
