The purpose of this study was to develop a relationship to evaluate the grip force (forcerel) using the electromyogram (EMGrel) of the flexor digitorum superficialis (FDS) and of the extensor digitorum (ED) according to the flexion-extension wrist angle (0t-e) and to the pronation-supination forearm angle (0p-s). Fifteen participants had to exert 3 levels of grip forces in 4 positions of the wrist combined with 3 positions of the forearm. The relationship is: forcerel = 0.0045 • 0t-e • EMGrel(FDS) + 0.48 • EMGrel(FDS)-0.0014 • 0t-e • EMGrel(ED) -0 .0016 • 0p-s • EMGrel(ED) • 0.4- EMGrel(ED) This relationship can be used to estimate grip force for levels of strength lower than 50% of the maximal voluntary contraction.
