The Effect of Cognitive Task Complexity on Healthy Gait in the Walking Corsi Test

Dual-task activities are essential within everyday life, requiring visual–spatial memory (VSM) and mobility skills. Navigational is an important component of VSM needed to carry out activities, but this often not included in traditional tests such as the Corsi block tapping test (CBT). The Walking Test (WalCT) allows both navigational be tested together, well allowing measures gait collected, thus providing a more complete understanding dual-task function. aim study was investigate effect increasingly complex cognitive task on healthy adult population, using WalCT body-worn inertial measurement unit (IMU) sensors. Participants completed CBT WalCT, where they were asked replicate sequences until no longer able correctly. IMU sensors worn shins throughout assess changes complexity increased. Results showed that there significant differences several parameters between completing relatively simple task. type used also appeared have impact some variables. This indicates even affected by complexity, which may limit function activities.
