How do you get a REBA score from a task video?
Soter's Video Ergonomic Assessment workflow takes a single video of a work task and reads it frame by frame. It identifies flexion and elevation angles for back, arms, legs, and neck, calculates REBA scores and risk levels for each posture, and returns up to three prioritized recommendations you can act on.
What the Video Ergonomic Assessment workflow does
An ergonomic assessment usually means watching a task, scrubbing back and forth, scoring postures by hand against a grid, and writing it up. This workflow does the frame-by-frame reading for you. You upload one video of the task, Soter watches it, identifies the back, arm, leg, and neck angles, and calculates a REBA score and risk level for the postures it sees.
The Safety Professional stays in control. Soter asks for load weight when the task involves lifting, then scores the postures and proposes recommendations. You review the angles and risk levels, adjust anything that does not match the task, and decide which recommendations to keep.
Where manual video scoring breaks down at scale
Three things slow a manual assessment to a crawl.
- Frame-by-frame scrubbing. Reading trunk, arm, leg, and neck angles off a video by eye means pausing and replaying the same clip many times, and two assessors rarely land on the same angle.
- Inconsistent REBA scoring. When the grid is applied by hand under time pressure, scores drift between assessors and between sites, so the risk picture is hard to compare.
- No record of the angles. A manual write-up records the final score but not the per-posture angles behind it, so a later reviewer cannot see how the number was reached.
How the workflow runs
- Upload the task video. Provide one video of the work task. A side angle that shows the back, arms, legs, and neck works best.
- Confirm load weight if there is a lift. Soter asks for the load weight when the task involves lifting or carrying, then starts the analysis.
- Read posture angles frame by frame. The workflow identifies flexion and elevation angles for back, arms, legs, and neck across the frames of the video.
- Calculate REBA scores and risk levels. Each posture is scored against the REBA grid, with a risk level assigned per body part.
- Get up to three recommendations. Soter combines the findings, rewatches the video, and returns up to three prioritized recommendations for the task.
Who uses this workflow
- Safety Professionals scoring repetitive lifting and reaching tasks without scrubbing video by hand
- Ergonomic advisors who need a consistent REBA score across many tasks and sites
- Site safety leads checking a new or redesigned workstation before it goes into use
- Insurance loss-control consultants reviewing a claimant's task on the carrier side
