| Research Abstract |
The present study aimed to investigate novel measures by quadriceps muscle thickness (MT) and echo intensity (EI) obtained from ultrasound, which can assess the risk of motor functional deterioration or sarcopenia among community-dwelling older people. Ultrasound images of quadriceps muscles were recorded in 913 community-dwelling older people, and MT and EI were measured. Relationships between these ultrasound measures and the risk of motor functional deterioration by "Kihon Check-list" or sarcopenia, such as skeletal muscle mass (SMM), knee extension strength and gait speed, were examined by a cross-sectional and a longitudinal analysis.
Although MT and EI were correlated with the risk of motor functional deterioration in the cross-sectional analysis, those were not correlated in the longitudinal analysis. However, MT was correlated with the future decrease of SMM. It may be possible to utilize this for the simple screening of sarcopenia.
