Objective: The purpose of this study was to compare the dynamic balance at different knee flexion angles (maximal knee flexion angles of 30° and 45°) on a 20% negative slope.
Methods: In an observational cross-sectional study, 19 healthy male participants performed a modified Star Excursion Balance Test on a 20% negative slope, whereas the left standing knee was restricted by a knee brace in a maximum of 30° or 45° flexion.
Results: The balance scores were significantly better in 45° knee flexion compared with 30° flexion in the composite reach and also in the percentage of reach in any of the test directions.
Conclusion: On a 20% negative slope, 45° knee flexion resulted in better dynamic balance than 30° knee flexion.
