Abstract(s)
The authors aimed to compare the postural phase ofgait initiation under single-task (gait initiation) and dual-task (gaitinitiation plus Stroop test) conditions in healthy subjects and insubjects with Parkinson’s disease (PD) in the early stages (Hoehnand Yahr scale<3). The postural phase of gait initiation wasassessed through the centre of pressure in single and dual task in10 healthy subjects and 9 with PD. The analysis indicated that inthe early stages of PD, an additional cognitive task did not affectthe displacement of the gait initiation. No significant effectsoccurred between the groups and within-subjects (p>.05). Also,no interaction was found between the groups and the conditions(single- and dual-task). Differences were found in the duration ofthe mediolateral postural phase (pD.003), which was higher inPD subjects than in healthy subjects. The findings suggest thatsubjects in the early stages of PD prioritize gait initiation, as theirmotor performance was similar to that of healthy subjects.
