abstract = "Early identification of at-risk gait helps prevent falls and injuries. The aim of this study is to investigate the relationship between approximate entropy (ApEn) and Poincar{\'e} plot indexes of elderly gait patterns and to test whether ApEn could be used as a reliable gait identifier for falls-risk. Minimum foot clearance (MFC) data of 14 elderly and 10 elderly participants with a history of falls and balance problems were analyzed. The ApEn values of MFC were significantly correlated with Poincar{\'e} plot indexes of MFC in the healthy elderly group, whereas correlations were absent in the elderly fallers group. Mean ApEn in the fallers group (0.18±0.03) was significantly higher than that in the healthy group (0.13±0.13). The higher ApEn values in the fallers group might indicate increased irregularities in their gait patterns and a loss of gait control mechanism. Results are useful for the early diagnosis of common gait pathologies.",
