Abstract
[Purpose] To examine the motor function of young-old and old-old subjects. [Subjects] Thirty community-dwelling elderly persons. [Methods] Maximum forward step length (MFS), maximum lateral step width (MLS), standing on tiptoe, plantar and dorsiflexion and the legs open and close tests in the sitting position, and the 3m zigzag walking test were evaluated. [Results] Differences in MFS, MLS, and standing on tiptoe were found between the young-old and old-old subjects, but not in plantar or dorsiflexion or the legs open and close tests in the sitting position, or in the 3m zigzag walking test. [Conclusion] Because differences were not found in plantar and dorsiflexion and the legs open and close tests in the sitting position, and the 3m zigzag walking test between the young-old and old-old subjects, it appears that these indices that are not much affected by age.
