Combining a Cognitive Concurrent Task with a Motor or Motor-Cognitive Task: Which Is Better to Differentiate Levels of Affectation in Parkinson’s Disease?

Table 3

Mixed ANOVAs and ANCOVAs comparing single and triple condition (intrasubject factor) for the fluency-pedaling-tracking triple task considering the disability groups (intersubject factor).

Tasks	Mixed ANOVAs	Mixed ANCOVAs
Fluency (with pedaling and tracking)	Condition: single > triple	—
	[F(1, 29) = 7.52, ,  = 0.21, observed power = 0.76]
Pedaling (with fluency and tracking)	Disability group: mild > moderate	Disability group: mild > moderate
	[F(1, 29) = 14.03, ,  = 0.33, observed power = 0.95]	[F(1, 28) = 13.39, ,  = 0.32, observed power = 0.94]
	Condition: single > triple	—
	[F(1, 29) = 57.95, ,  = 0.66, observed power = 1.0]
Tracking (with fluency and pedaling)	Condition: single > triple	—
	[F(1, 29) = 12.38, ,  = 0.30, observed power = 0.93]
	Disability group x condition:	Disability group x condition:
	[F(1, 29) = 7.86, ,  = 0.21, observed power = 0.77]	[F(1, 28) = 7.86, ,  = 0.22, observed power = 0.77]
		Bonferroni:
		(a) Low > high in single condition [F(1, 28) = 25.33, ,  = 0.47, observed power = 0.99]
		(b) Single > dual in the mild group [F(1, 28) = 7.48, ,  = 0.21, observed power = 0.75]
