Figure 5. Mean 10 cm-VAS scores comparison between postures with and without the wearable chair.

Mean 110 centimetres (cm)-visual analog scale (VAS) scores after the task with the wearable chair (n = 6, error bar: SD) and the task without the wearable chair (n = 6, error bar: SD). Black bars: with the wearable chair; white bars: without the wearable chair. The score at the left-hand end of the VAS is defined as -5, and the score at the right-hand end as 5. A score of 0 in the middle means neither. The mean value after the task is shown.
