Abstract

In rehabilitation, emotional aspect is one key factor to motivate patients to reach their full recovery. Our previous study developed wireless PAM driver as walking-support device and experimentally evaluated its effectiveness in physical ability, but has not performed evaluation on emotional aspect yet. Therefore, this study experimentally evaluates cognitive load and its relationship with physical ability (i.e. performance and joint motion) on walking support using our PAM driver with variations of walking conditions. We obtained tendency of double-blink rate as rapid serial blinks to evaluate cognitive load during walking. In addition, we obtained correlations between gait velocity and blink rates, indicating that cognitive load was affected by walking speed (performance) more than joint motion (swing support).
