| Research Abstract |
We investigated the relation between falling and power spectrum entropy of acceleration time-series during gait (entropy index) for a total of 2833 community dwelling elderly persons over three years. If a movement's entropy index is higher than others, the movement is more unstably. If a movement's entropy index is higher than others, the movement is more unstably.The results shows that the fallers' entropy indices indicated higher values (p<0.05) by comparing non-fallers and first-fallers at 3rd year, using the entropy at 1st year. And also, Logistic regression analysis revealed that entropy index was a risk factor for falls (odds ratio=5.49; p<0.05). S0 the entropy index was a factor which has biggest influence compared with the index used conventionally, such as a walking speed, muscle strength, balance, stride time variability.
