Dual-Task Performance in GBA Parkinson’s Disease

Table 3

Dual-task costs.

	GBA-PD	iPD	value
Walking while checking boxes [%]	11 (−11–48)	9 (−0.6–27)	0.88
Checking boxes when walking [%]	25 (−15–100)	12 (−10–44)	0.09
Walking while subtracting [%]	35 (27–59)	40 (33–52)	0.57
Subtracting when walking [%]	−39 (−121–13)	−16 (−78–39)	0.09

Values are given in median (range). A logistic regression analysis, with the motor part of the Unified Parkinson’s Disease Rating Scale and the Montreal Cognitive Assessment as covariables, including likelihood ratio was used to calculate values. Significance level was set at . GBA-PD = Parkinson’s disease patients carrying a heterozygous glucocerebrosidase mutation; iPD = idiopathic Parkinson’s disease.
