Journal ArticleDOI
Biomechanical model of the human shoulder joint--II. The shoulder rhythm.
TL;DR: In this paper, a method to investigate the rhythm of the human shoulder, i.e. the interplay between the motion of constituent parts of the shoulder, has been devised and tested.
Journal ArticleDOI
Biomechanical model of the human shoulder--I. Elements.
TL;DR: In a first step of a biomechanical modelling of the human shoulder the points of application of muscle forces to the bones were determined in a dissection study on four human shoulder specimens.
Journal ArticleDOI
Shoulder pain and heavy manual labor.
TL;DR: The biomechanic studies confirmed the view that the shoulder muscles are heavily loaded when the arm is elevated and the strain on the supraspinatus muscle in overhead work is an important factor contributing to prolonged shoulder disability.
Journal ArticleDOI
Voluntary redistribution of muscle activity in human shoulder muscles.
Gunnar Palmerud,Roland Kadefors,Hȧkan Sporrong,Ulf Järvholm,Peter Herberts,Christian Högfors,Bo Peterson +6 more
TL;DR: Four shoulder muscles were examined with electromyography in abducted arm positions and it was found that the subjects could reduce the EMG activity voluntarily by 22-47% in the trapezius muscle while keeping different static postures.
Journal ArticleDOI
Autobalancing of Rotors
Peter Bövik,Christian Högfors +1 more
TL;DR: In this article, it was shown that plane rotors with one or two particles free to move, subject to viscous damping, exhibit autobalancing, a property attributed to non-autonomous systems possessing an hyperbolic stable fixed point in the (non-extended) phase space for an open domain in parameter space.
