Figure 2. Posture scores for user trial (REBA).
Four postures were analysed with REBA: lifting the bag from the vehicle, opening
a door, walking upstairs, and placing the bag on the ground. The REBA scores are
shown in Figure 2 (n = 144). The Green Rucksack consistently recorded low scores
whereas CURE, due to its size and weight, had the poorest postures. None of the
21 postures analysed reached the highest level of risk in the REBA scale (>11).
Twelve of the postures analysed for the Green Rucksack recorded the lowest level
of risk (=1) where no changes are required.
The physiological evaluation created 3 datasets:
