Read RULA, REBA, NIOSH and manual-handling scores

Rapid Upper Limb Assessment looks at arm, wrist and neck posture, plus muscle use and load. It suits seated and standing tasks where hands and arms do the work.

Rapid Entire Body Assessment adds the trunk and legs. Use it for tasks that involve bending, twisting, kneeling or awkward whole-body positions.

The NIOSH lifting equation gives a recommended weight limit for a lift. Snook tables cover push, pull and carry. The WISHA lifting calculator and the Manual Handling Assessment Charts (MAC) give quick manual-handling risk grades. Together they show whether the load and the movement are within safe limits.

Each score comes with a plain-language verdict and risk level. Annotated pose snapshots show the exact moments that drove the score, for example a bent neck for most of the cycle or a wrist deviating during a reach.

KnowErgo pairs each finding with a practical change, such as raising the work surface or adding a grip point. The recommendation becomes the corrective action your team approves.
