Table 3 Effects of lighting on gait

From: Shedding light on walking in the dark: the effects of reduced lighting on the gait of older adults with a higher-level gait disorder and controls

  Patients with HLGD (n = 22) Controls (n = 20)
  Normal Lighting Near Dark (P-value*) Normal Lighting Near Dark (P-value*)
Average Stride Time (sec) 1.30 ± 0.17 1.29 ± 0.15 (0.376) 1.17 ± 0.12 1.17 ± 0.12 (0.912)
Stride Time Variability (%) 5.6 ± 2.3 6.8 ± 2.3 (0.005) 3.6 ± 1.2 4.1 ± 1.9 (0.295)
Average Swing Time (%) 33.9 ± 2.7 32.5 ± 3.7 (<0.001) 35.7 ± 3.0 35.5 ± 3.2 (0.015)
Swing Time Variability (%) 7.0 ± 2.9 10.1 ± 4.7 (<0.001) 4.5 ± 2.4 5.1 ± 2.5 (0.365)
Walk Time (sec) 106.3 ± 44.2 124.4 ± 57.1 (<0.001) 72.8 ± 20.8 84.2 ± 33.5 (0.013)
  1. *P-values shown in parentheses are based on within group comparisons between near dark and normal lighting. All measures of gait were different (p < 0.01) in the two subject groups, both under normal lighting and in near darkness. Walk time is the time to complete the 54 meter walk.
