This study evaluated mental workload using the {NASA} Task Load Index ({TLX}), a multi-dimensional rating procedure with six subscales: Mental Demands, Physical Demands, Temporal Demands, Performance, Effort, and Frustration. Able-bodied and motor disabled participants completed the survey after performing {EEG}-based {BCI} Fitts' law target acquisition and phrase spelling tasks. The {NASA}-{TLX} scores were similar for able-bodied and disabled participants. For example, overall workload scores (range 0-100) for 1D horizontal tasks were 48.5 ({SD} = 17.7) and 46.6 ({SD} 10.3), respectively.
