The Single-Task-Walk (STW) condition required participants to walk around an electronic walkway at their “normal pace”. The cognitive interference task involved participants reciting alternate letters of the alphabet (A, C, E…) out loud. The Dual-Task-Walk (DTW) condition required participants to perform the two single tasks at the same time. Participants walked on the instrumented walkway in three continuous loops, separately, under STW and DTW conditions. Test conditions were counterbalanced.
