Estimation of three degrees of freedom of wrist movement from electromyogram using Kernel Ridge Regression

This work describes the application of nonlinear kernel based regression method for prediction of 3 degrees of freedom (DoF) wrist movement from surface electromyogram (sEMG) signals. Here, two semicircular motion trajectories have been used, where multiple DoFs are engaged in a free wrist movement and near the both extremities of the motion profile all the three DoFs of wrist are involved. Compared to earlier studies this is novel in the fact...
