Table 1.

Age, Gait Speed, Slip Severity, and Degree of SDD Severity for Slow and Fast Walkers

	Slow Walkers (N = 26)	Fast Walkers (N = 24)
Age (y), /Mean (SD)	66.3 (12.1)	61.2 (16.9)
Gait speed* (m/s)/Mean (SD)	1.09 (0.08)	1.30 (0.07)
Slip severity* (m/s)/Mean (SD)	0.70 (0.50)	1.25 (0.58)
SDD distribution† (caudate nucleus)	9 M, 7 Mod., 10 S	7 M, 10 Mod., 7 S
SDD distribution† (putamen)	9 M, 6 Mod., 11 S	7 M, 11 Mod., 6 S

Notes: M = mild; Mod. = moderate; S = severe; SDD = striatal dopaminergic denervation.

Statistical significance: *p ≤ .01.
