结局指标
主要结局
Change in Balance
时间窗: 13 minutes
Balance was assessed during a 13-minute nocturnal light exposure (4 different conditions) and differences between the conditions were assessed. To determine goodness of balance while walking, the variability in stride length (i.e., variance in stride-to-stride length) was calculated in each of the conditions. Increased variability in stride length is associated with increased risk of falling.
