Which tasks are hurting people?
REBA and RULA scores for every frame of every filmed task.
AI Ergonomic Study: See Every Risk. Score Every Posture.
An AI ergonomic study from ordinary video: LeanSuite maps 18 body joints, scores REBA and RULA automatically and flags the postures that need a fix.

What it answers
One phone video in, the scores out
Film the task and upload the file. The AI drafts the posture scores. You check them.
Which part of the body is at risk?
A color-coded heatmap by body region, with a ranked list of regions.
What is the worst moment in the task?
The highest-risk frames are clipped for you, so nobody scrubs through footage.
What should we change?
Each flagged risk driver comes with an engineering-control suggestion, and you can re-score after the change.
Ergonomic Study
Why Ergonomic Risk Goes Unseen
Why a manual ergonomic study misses risk.
Manual Assessments
Ergonomists can only assess a small share of the tasks on the floor.
Late Discovery
Strain injuries often show up only after years of repetitive work.
No Trending
Risk scores aren't recalculated when the layout changes.
How it works
How the AI Ergonomic Study Works
Film the task, let the AI track posture frame by frame, and get REBA and RULA scores.
1. Film the Task
Standard phone footage is enough. No markers, suits or special cameras.
2. Pose Estimation
The AI maps 18 body joints on every frame of the video.
3. REBA / RULA Score
Get REBA and RULA scores and a risk heatmap, with the worst frames highlighted.
From video to result
Who does what, in order
The AI does the scoring. You decide what is right.
You
Film the task
A phone, tablet or fixed camera on the operator. No markers or suits.
You
Upload and tag
Pick the ergonomic study and tag the workstation.
The AI
Scores every frame
Pose on 18 joints, REBA or RULA scores and the worst frames, each linked to its source frame.
You
Review and act
Override and re-score any frame, then choose the countermeasure.

Features
The AI Ergonomic Study in One Workflow
Built for industrial engineers, EHS and CI leads. No AI expertise required.
Feature 01
18-Point Pose Estimation
AI tracks 18 body joints on every frame and builds a skeletal model of the worker's posture. No suits or markers, just the footage you already have.
Full-body joint tracking, frame-by-frame
Works from standard video, no hardware
Skeletal posture model on every frame
Feature 02
REBA + RULA Scoring
Pick REBA or RULA per task and the score comes straight from the pose data, with no angle measuring or scoring sheets. Both run on the same video.
Automatic REBA and RULA scoring
Per-task methodology selection
No manual angle measurement
Feature 03
Risk Heatmaps
A color-coded heatmap shows where risk concentrates on the body, so teams see which regions need attention first.
Color-coded body-region risk mapping
Instant visual risk prioritization
Generated automatically from scoring data
Feature 04
Worst-Frame Capture
AI scans every frame and clips the highest-risk moments, so supervisors review the worst posture without scrubbing through footage.
Auto-flagged highest-risk frames
Ready-to-review evidence clips
No manual footage scrubbing
Feature 05
Action Recommendations
Each flagged risk driver comes with an engineering-control suggestion tied to the posture or motion causing it.
Risk-driver-linked control suggestions
No guesswork on remediation
Actionable, not just diagnostic
Feature 06
Audit Log
Every assessment, score and recommendation goes into an audit trail, ready for an OSHA inspection or internal EHS review.
Automatic OSHA-ready documentation
Full assessment-to-recommendation trail
No manual record assembly
From video
REBA and RULA scores from one video of the task
Pose estimation scores every frame, so you see which tasks drive injury exposure.
Film the task
Record the operator on a phone, tablet or fixed camera. No markers, suits or special hardware.
Upload and tag
Drop the video into LeanSuite, pick the ergonomic study and tag the workstation.
Get the scores
Pose estimation scores every frame with REBA and RULA; you review and can re-score any frame.
Review and re-score
Override and re-score any frame manually, then act on the recommended countermeasures.
What you get back
- REBA and RULA scores on every frame
- Body-region heatmap (neck, back, shoulder, wrist)
- Risk severity by task element
- Recommended jig and fixture countermeasures
- Every score linked to its source frame
- Time and motion data from the same footage
Who it is for
What each role gets from the same video
Industrial engineers
Posture scores and suggested controls drafted from the footage, so your time goes on the fix.
EHS and safety
Scored tasks with timestamps and source clips, and an audit trail for internal reviews.
Continuous improvement leads
The worst frames and risk drivers for each task, to take straight to a Kaizen.
Operations leaders
Risk by task, and the score again after a layout or tooling change.
Honest limits
What it can and cannot do from video
What it does
- Reads video you record and upload: 1080p phone footage is enough, single uploads up to 4 hours.
- Scores REBA or RULA from the pose it tracks on every frame, and lets you re-score any frame.
- Links every score to the frame it came from, so each one can be checked.
What it does not
- It does not watch a live camera or send alerts at the station. It analyses files you upload.
- It does not replace your judgment or an ergonomist's: you review the scores.
- It cannot score a person it cannot see in the footage.
Why It Matters
Why Teams Choose It
A manual ergonomic assessment relies on an ergonomist with worksheets, misses tasks and starts over when the process changes. LeanSuite scores every filmed task frame by frame and keeps the audit trail.
100% Coverage
Score every task, not just the ones an ergonomist sees.
Compliance Ready
Defensible records for OSHA and internal EHS audits.
Lower Injury Rates
Remove risk before it turns into a claim.
FAQs
Frequently Asked Questions
An ergonomic study measures the physical strain a task puts on the body, usually by scoring postures with REBA (whole body) or RULA (upper limbs), so the riskiest tasks are redesigned first.
Film the task on a phone and upload it. The AI estimates the pose on every frame, scores REBA or RULA, and flags the worst frames with suggested engineering controls.
No. A standard smartphone camera is enough, with no markers, suits or motion-capture rigs.
The model tracks 18 joints on every frame of the video. You can review and re-score any frame.
Yes. Unlike sampling-based assessments, every filmed task gets a full REBA/RULA score.
Yes. Reports include methodology, timestamps and source clips for audit defensibility.
Yes. PPE detection and NIOSH lifting equation modules are available alongside REBA/RULA.
Yes. Each person is tracked and scored independently.
Re-score after each layout or tooling change; the dashboard trends risk by line, cell and task.
No. You record the task and upload the file, and the AI analyses that video. It does not send live alerts at the station.
No. You can start with one video from a phone.
Yes. Retention is configurable, and access is role-based with full audit logs. Footage is encrypted in transit and at rest, processed in your own tenant and not used to train external models.
