If the manikin lifts the load correctly, which means it bends the knees and straightens the back, all vertebrae stay together as one and the load is spread on the whole vertebra. If the manikin lifts the load with straight legs and bends the back, the spine is bent apart and clefts appear between the vertebrae. The patient can clearly see that the load is pressing on the front part of the vertebra which can cause disc damages. A valuable aid for each practice.
