Elderly people in a new study cut their risk of falling by more than half after they took classes in eurhythmics, an
exercise-and-music
program designed for young children... Even after the classes ended, the participants maintained their improvements in balance, walked with a more regular gait and were better able to walk while doing other things."
FWIW, when I went to PT, they gave me exercises to try to retrain my vestibular system that, while not miraculous, were helpful.
