Aim of the project will be to utilize a high density surface EMG electrode grid to study basic mechanisms in muscle functioning in the lumbar region, and to examine what impact individual factors such as gender and strength may have on research variables. In the first part of this project we expect to reveal an association between muscle activity pattern, strength and fatigue/endurance in healthy, pain free persons. In the second part we expect to find differences between healthy persons and a low back pain population regarding muscle activation patterns and fatigue/endurance. We also expect an association between low back pain patients psychometric profile and muscle activation patterns.
