Abstract

Background & Aim: The objective of the present study was to establish the reliability of measuring diaphragm muscle thickness using ultrasound imaging among older adults. Method: Twelve Malay women aged sixty and above who met the inclusion criteria participated in this study. Diaphragm muscle images were captured using ultrasound imaging. Three ultrasound images were captured during quiet end inspiration and expiration each. The mean value of 5 points along zone of diaphragm thickness from each image was used for analysis. The recorded images were analysed using MATLAB. Two-way mixed model of Intra-class correlation coefficient (ICC) was performed to determine the reliability of diaphragm muscle thickness. Results: The mean±standard deviation of diaphragm thickness during quiet inspiration and expiration was 0.27±0.05 and 0.19±0.04, respectively. The ICC of three images during quiet inspiration and expiration was 0.924 and 0.949, respectively. Discussion & Conclusions: The present methodology of diaphragm muscle thickness measurement demonstrated excellent reliability. The present technique and measurements of diaphragm muscle thickness using US is reliable and can be used for further studies.
