The Cognition of Maximal Reach Distance in Parkinson’s Disease

Table 1

Means and standard deviations of ED, AD, DEA, and absolute value of DEA in each direction.

(a)

		Front	Dominant	Nondominant
	ED cm/cm	0.51 ± 0.05	0.52 ± 0.06	0.52 ± 0.06	n.s.
Healthy elderly	AD cm/cm	0.53 ± 0.03	0.52 ± 0.03	0.52 ± 0.02	n.s.
	DEA cm/cm	−0.02 ± 0.04	0.00 ± 0.05	−0.01 ± 0.06	n.s.
	|DEA| cm/cm	0.04 ± 0.03	0.04 ± 0.03	0.05 ± 0.03	n.s.

(b)

		Front	Milder side: MS	Severer side: SS
	ED cm/cm	0.47 ± 0.08	0.47 ± 0.08	0.47 ± 0.09	n.s.
PD	AD cm/cm	0.50 ± 0.03	0.50 ± 0.03	0.50 ± 0.03	n.s.
	DEA cm/cm	−0.04 ± 0.06	−0.04 ± 0.07	−0.04 ± 0.07	n.s.
	|DEA| cm/cm	0.07 ± 0.05	0.06 ± 0.05	0.07 ± 0.05	n.s.

Mean ± SD [cm/cm].
The one-way ANOVA was performed with each item.
ED: estimated distance, AD: actual distance, DEA: difference between ED and AD, |DEA|: absolute value of DEA, and n.s.: not significant.
