Figures & data

Table 1. Characteristics of healthy older adults and patients with COPD.

Figure 1. The ΔO2Hb in the right (A) and left (B) dorsolateral PFC during the preferred and fast paced walking single and dual tasks in healthy adults and patients with COPD. The ΔO2Hb during preferred and fast walk were higher in patients with COPD compared to older adults in the right dorsolateral PFC. In older adults, ΔO2Hb was higher during preferred paced walking dual versus single task in the right and left dorsolateral PFC and during fast paced walking dual versus single task in the right dorsolateral PFC (A).

* indicates statistical significance at p < 0.05. BS: backwards spelling; FPW: fast paced walking; PPW: preferred paced walk.
