The quantitative and qualitative differences in trunk muscles of aspiration pneumonia over 65 years male with bedridden condition in the independence of sitting up motion

: The purpose of this study was to clarify quantitative and qualitative differences in trunk muscles due to the difference in the independence of sitting up motion. The subject was over 65 years male patient who was hospitalized with aspiration pneumonia at was bedridden. It was compared with the partial assistance group and whole assistance group due to difference in independence of sitting up motion. The cross-sectional area (CSA) of the muscle was measured using the CT image of the trunk muscle. In addition, the area based on the CT value of the muscle or fat in the measured CSA was measured as %FCSA and %IMF. The result of the whole assistance group compared with the partial assistance group, there was a significant decrease in erector spinae muscle CSA. In % FCSA, there was a significant lower of the abdominal oblique muscle group, quadratus lumborum muscle, the multifidus muscle, and the erector spinae muscle. In %IMF, there was a significant higher in all muscles except for the rectus abdominis muscle. Based on the results, the qualitative difference in the trunk muscles of the whole assistance group compared with the partial assistance group showed the possibility of being related to the independence of sitting up motion.
