Spectral Elektromyografie(EMG)-mapping in the lumbar region and EMG-polygraphy of the functionally important trunk muscles during systematised lifting tests

Status:

completed 12/1996

Aims:

Determining the important strain- and EMG-parameters and their correlation when lifting and carrying loads

Activities/Methods:

Determination of spine-muscle activities during, lifting and carrying loads

Results:

The load/strain during lifting work is not restricted to the lumbar area: as well as the trunk muscle system the shoulder girdle muscle system is also considerably involved; the maximum demands made on the muscular system occur in the lumbar area during lifting of weights and in the shoulder girdle area during lowering of weights; there is no linear increase in EMG-performance with weight (saturation characteristic), maximum work is transferred to the cranial-lateral area with increased load.
