Not medical advice
Content on ViveLab, including guides about posture, eye strain, repetitive strain injury and musculoskeletal disorders, is general information. It is not medical advice and does not replace diagnosis or treatment by a qualified healthcare professional. If you have pain, numbness, tingling or other symptoms that persist, see a clinician.
Not a substitute for a competent assessor
REBA, RULA and the NIOSH lifting equation are screening and design tools. ViveLab's AI analyzer estimates joint angles from images and may be wrong, especially for hidden limbs, wrists and depth. Scores should be reviewed by a competent person and combined with other information (worker feedback, injury records, task duration and organisational factors) before decisions are made.
Not legal or compliance advice
References to OSHA, HSE, CCOHS, NIOSH and other bodies are for information only. Requirements vary by country, state and industry. Check the regulations that apply to your workplace.
Calculator estimates
Desk and monitor heights are estimated from average body proportions and are a starting point only. Individual proportions vary; adjust for comfort.
