Industrial Lumbar Motion Monitor™ (iLMM3™)

The iLMM3 is the third and most advanced version of the Industrial Lumbar Motion Monitor introduced almost 20 years ago and used by leading organizations worldwide.

The iLMM3 measures the position, velocity and acceleration of the spine in the sagittal, lateral, and twisting planes and this data is used by the LBD (Low Back Disorders) risk model to identify risk factors. Some of the new features include:

Ergonomists and Researchers Can:

The LBD (Low Back Disorders) risk model can be used to identify which elements of a job led to an increase in LBD risk and thus which elements need to be changed. It is important to understand that LBD risk can never be completely eliminated, but by quantifying risk levels, the model can help determine if a job is within acceptable levels of risk. It can additionally provide a "benchmark" of LBD risk for a job, allowing comparisons between the original design and possible job alterations. The LMM breaks the work into individual job tasks for analysis of the specific range of motion, velocity and acceleration moments on the lumbar spine. The LMM allows you to compare the task to a normative database of common variables associated with jobs that have a high incidence of low back disorders. These comparisons, combined with the data from the job site assessment, allows you to recommend ergonomic changes.
