Traditional ergonomic assessments have always required trained specialists, paper forms, stopwatches, angle measuring tools, and hours of data entry after the fact. The process was slow, expensive, and inaccessible to most small and mid-sized workplaces that couldn’t afford a dedicated ergonomist.
Today, with AI-powered mobile apps like Ergzo, any safety officer, HR manager, or occupational health professional can conduct a complete, scientifically valid ergonomic risk assessment using nothing more than the smartphone already in their pocket. Here is exactly how to do it.
Open Ergzo and tap “New Assessment.” If the worker performs whole-body physical tasks like lifting, carrying, or bending — choose REBA. For primarily upper-limb repetitive work like assembly, data entry, or sewing — choose RULA. For office workstation evaluations, choose ROSA. For manual lifting tasks with known load weights, use NIOSH.
For live assessment, point your phone camera at the worker — Ergzo’s AI will automatically detect body landmarks and track joint angles in real time. For gallery upload, use any existing photo or video and upload it into the app. A side-view or 45-degree angle typically gives the most accurate results.
After posture detection, Ergzo will ask a few short follow-up questions specific to your chosen tool — such as load weight (for REBA/NIOSH), task duration and frequency (for RULA/OCRA), or grip type and coupling quality. These take under 2 minutes and significantly improve the accuracy of the final risk score.
Ergzo instantly generates a colour-coded risk score: Green (Low), Orange (Medium), Red (High), or Dark Red (Very High). A body map highlights exactly which joints are at risk — neck, shoulder, elbow, wrist, trunk, or lower back.
For every high-risk body part, Ergzo provides specific, actionable recommendations — adjusting workstation height, introducing tool modifications, scheduling micro-breaks, or redesigning the task sequence. The app auto-generates a corrective action plan that can be assigned to a supervisor or shared with management directly.
Tap “Export” to download a professionally formatted PDF report with risk scores, body part breakdown, recommendations, and the action plan. You can also export raw data in CSV or Excel format for record-keeping, insurance documentation, or compliance audits.
For the most accurate AI pose detection, position yourself at a 90-degree side angle to the worker. This gives Ergzo the clearest view of trunk angle, arm elevation, and knee bend — the three most critical measurements in most assessment tools.
Most workers perform several different tasks in a single shift. A warehouse worker might lift boxes (REBA), operate a forklift (ROSA), and do repetitive packing (RULA). Assess each task separately — Ergzo organises all sessions under the same worker profile so you can track cumulative risk across their full work day.
The most powerful use of Ergzo is measuring whether your ergonomic improvements actually worked. After implementing a change — a new anti-fatigue mat, a height-adjustable workstation, a modified lifting technique — reassess the same task. Ergzo automatically calculates the before-and-after risk score difference so you can present data-backed results to management.
A complete Ergzo assessment — from opening the app to downloading the PDF report — takes between 4 and 8 minutes per task. Compare this to traditional paper-based REBA/RULA assessments which typically take 20–45 minutes including data entry, scoring, and report writing. Ergzo reduces assessment time by over 80%, making it practical to assess every worker at every workstation rather than just a sample.
