 note = {Objective: This study aimed to investigate the physical performance and cognitive function related to the second fallin older adults who have suffered previous falls and fractures.
Method: This prospective cohort study included older adults who were admitted to hospital with an orthopedic fallrelatedinjury and who completed 12 months of follow-up investigations. We evaluated the Berg Balance Scale（ BBS）,Timed Up and Go Test, Four-Square Step Test, walking speed, 30-Second Chair-Stand Test, 6-Minute Walk Test,Falls Efficacy Scale, Functional Independence Measure, and Mini Mental State Examination. Telephone interviewswere used to investigate the fall status of the subjects monthly for 12 months. Principal component analysis was usedto derive orthogonal factor loading. Logistic regression analysis was used to determine which factors were associatedwith a second fall.
Results: The first three principal components （PC1, PC2, PC3） accounted for 77.2% of the variance in the data athospital discharge. The principal components biplot, showed that the BBS an independent comprehensive indicator.The logistic regression analysis results showed the BBS score to be a risk factor for falls （odds ratio=0.81, 95%confidence interval=0.64-0.95）.
Conclusion: The BBS score was associated with the risk of second falling in older adults with a history of fractures},
