Methods: Retrospective data analysis was performed on time for 3MBW test, forward walk tests (Timed Up and Go, TUG cognitive, and 10-Meter Walk), and the 5 times Sit-to-Stand test. A receiver operating characteristic curve analysis was completed to determine fall cutoff scores, and the optimal area under the curve (AUC) with sensitivity/specificity values was defined. Results: The 3MBW test at 4.2 seconds had the highest AUC (AUC = 0.699). Persons with Parkinson disease with advanced disease were slower for each test; the 3MBW was the only test that was significantly different across disease severity. Conclusion: The 3MBW test had the highest overall accuracy for retrospective falls and should be considered as part of battery of tests among persons with Parkinson disease.

However, recent research has demonstrated that backwards walking is more sensitive at identifying age-related changes in mobility and balance compared with forward walking. No clinical test of backwards walking currently exists. Therefore, this article describes a novel clinical test of backwards walking, the 3-m backwards walk (3MBW), and assessed whether it was associated with 1-year retrospective falls in a population of healthy older adults. Diagnostic accuracy of the 3MBW was calculated at different cutoff points and compared with existing clinical tests. This study was a retrospective cohort study including residents of a retirement community without a history of neurological deficits. Demographics, medical history, and falls in the past year were collected, and clinical tests included the 3MBW and the Timed Up and Go (TUG), the 5 times sit-to-stand, and the...
