초록
Considerable noise is sometimes associated with degeneration of the hee joint surface. Such noise may indicate roughness or softening of the cartilage surfaces, and may be a useful index for early disease. In this study, we have evaluated arthritic pathology using the acoustical analysis of knee joint sounds. During sitting and standing periods, subjects' active knee flexion and extension were monitored. Fundamental frequency, mean amplitude of pitch, jitter and shimmer were analyzed according to the position and the joint angle. The result showed that the fundamental frequency of the 2nd patient group and standing position was higher than the others, and that the pitch of sounds changed unstably. These results suggest that an analysis of knee joint sound might assist non-invasive diagnosis of an articular pathology.
