Both modules are used to assess tasks involving awkward postures.

The Postures [OWAS] module analyzes more postures, but with fewer details than the Postures [REBA] module:

• Postures [OWAS] analyzes the risk of a random sampling of working postures, whereas Postures [REBA] analyzes the most frequent and/or arduous postures.

• InPostures [OWAS], each posture analyzed considers the position of the back, arms and legs, and the force exerted. Postures [REBA], analyzes for each posture the position of the trunk, neck, legs, arms, forearms and wrists, force, grip type and muscle activity.
