Fourier-Based Footfall Placement Variability in Parkinson’s Disease

Table 2

Average gait parameters of controls and low and high Parkinson’s disease (mean±SD).

	Controls	Low PD	High PD	F (2, 62), P
FAP	91.40±9.07	83.30±16.26	73.7±15.51,	8.309, <.001	0.21
Walking speed (cm/s)	125.17±23.36	89.81±24.59	74.94±25.25	24.018, <.001	0.43
Step width (cm)	64.83±9.63	49.88±10.75	41.87±9.47	27.405,<.001	0.47
Step length (cm)	63.94±9.89	48.08±11.36	38.92±10.59	28.917,<.001	0.48
Step time (s)	0.51±0.08	0.54±0.07	0.53±0.09	0.573, 0.567	0.02

a, b, and c denote specific group differences from post hoc analysis. p<.05 difference between low PD and controls. p<.05 difference between high PD and controls. p<.05 difference between PD groups. FAP means functional ambulation profile score in GAITRite.
