Abstract (Englisch)

This Concerted Action was set up to co-ordinate research efforts to advance the scientific base needed to prevent muscular pain related to the use of computer input devices, and to formulate recommendations for the technical and organisational design of work involving computers. The scientific hypothesis of the project was that in computer work, low threshold motor-units in muscles of the neck-shoulder-arm- hand area may be active over long periods of time, not allowing physiological restitution and recovery.
Indeed, using advanced electrophysiological techniques, continous firing of some motor units was demonstrated. Such activation was shown to be provoked by biomechanical loading, psychological or mental stress, or a combination thereof.
The work was divided into 13 Work Packages. The Swiss partners contributed i) to develope a decomposition algorithm, which allows to decompose the EMG into constituent motor-unit firing trains of long-term registrations (Institute for Signal and Information Processing, ETHZ), ii) experiments on motor unit behavior in repetitive and one-sided tasks (Institute of Hygiene and Applied Physiology, ETHZ) and iii) measurements in patients with work-related neck pain (Department of Rheumatology and Institute of Physical Medicine, University Hospital Zurich).
