摘要: Abstract The current study aimed to examine postural control performance during a single-leg balance task in elderly individuals with and without previous history of lateral ankle sprain (LAS). Eighteen adults LAS (mean age = 66 years old) 12 healthy controls age = 65 years were included the study. Participants performed three trials an eyes-opened condition for 20-s. Center pressure (COP) trajectories anteroposterior (AP) mediolateral (ML) directions collected force plate. following measures calculated AP ML directions: 1) Sample Entropy (SampEn); 2) Approximate (ApEn); 3) mean Time-to-Boundary minima TTB); 4) COP velocity (COPV). Older-age participants exhibited lower ApEn-AP, SampEn-AP, SampEn-ML values compared (p
