Characteristics of participants.
Fig 5.
Shoulder abduction with the Greifer, the Axon-Hook and the NA side during the BBT.
Significant (*p < 0.05) higher shoulder abduction with the Greifer than with the Axon-Hook and than with the NA side.

Time with shoulder abduction > 60° with the Greifer, the Axon-Hook and the NA side during the BBT.
The thick black line indicates the threshold of 10%, considered as the percentage of time in a workday above which patients are at risk of developing MSD. There was no statistical difference between the groups (p = 0.92 for mixed-design analysis of variance).

BBT scores with the Greifer, the Axon-Hook and the NA side.
Main effect of the “Hand” (F = 90.32; p < 0.001; ηp2 = 0.92) with a significant greater score with the NA side compared to the Axon-Hook (**p < 0.001) and to the Greifer (**p < 0.001). No significant difference was observed between the Greifer and the Axon-Hook (p = 0.60).
