HOW THE BACK WORKS

Dual Function:

• 33 vertebrae

• 24 moveable

• 7 Cervical (support skull)

• 5 Lumbar (bend at waist)

• 5 Sacral (fused)

• 4 coccyx (fused)

THE 3 STEPS OUR PROGRAM PROVIDES TO RESOLVE

ERGONOMIC-RELATED ISSUES:

Assessment is a review of process design, equipment, previous analyses, and incident reports with follow-up written assessment recommendations.

Job Task Analysis (JTA) is an on-site analysis of video recording and/or digital pictures, measurement gathering (force, weights, reach distances, lifting heights, etc), with follow-up written recommendations.

Training is custom per assessment findings, JTA data and/or WC stats to support the need of group trainings specific to the PD.
