Quantitative analysis of strain factors when lifting and carrying from defined reference movements

Status:

completed 12/1996

Aims:

Prevention of work-induced damage of spine

Activities/Methods:

Analysis of muscle activities of the spine during lifting and carrying loads

Results:

Lifting exerts strain mainly on the small erector spinea muscle; no differences with regard to spinal strain between lifting and lowering weights; spinal strain is determined by the weight of the load; the influence of the horizontal movement distance is minimal, the influence of the vertical starting point of the load is greater; the handiness of the load (handling situation) has a significant influence on the load situation on L5-S1 and the demands on the muscle system.
