LMM (Leitmerkmalmethode) is a recognized method for assessing physical strain from manual lifting, holding and carrying tasks, published by Germany's Federal Institute for Occupational Safety and Health (BAuA). It scores five factors — load weight, how the load is gripped, body posture, unfavorable working conditions, and how the task is organized across the day — and combines them into a single strain score.
This is an automated screening estimate based on your uploaded video, not a certified ergonomic assessment, and it does not replace a workplace risk assessment by a qualified professional.

<20 pointsLimited risk
20 – <50 pointsSlightly more risk

About the RULA ergonomics assessment
RULA (Rapid Upper Limb Assessment) is a recognized method for assessing postural and muscular loading on the neck, trunk, and upper limbs — published by researchers at the University of Nottingham. It scores seven body regions — upper arm, lower arm, wrist, wrist twist, neck, trunk, and legs — and combines them into a single risk score.
