Previous studies suggested that increasing speed has an effect on human walking features such as joints and muscles range of motion, related spatio-temporal parameters and muscles activation patterns. However, such an effect on more complicated indices e.g. muscle synergies, minimum angular jerk and cross correlation between different types of biomechanical gait data has not been studied in large...
In recent years, a significant effort has been invested in the development of kinematics-decoding models from electromyographic (EMG) signals to achieve more natural control interfaces for rehabilitation therapies. However, the development of a dexterous EMG-based control interface including multiple degrees of freedom (DOFs) of the upper limb still remains a challenge. Another persistent issue in...
Variations in kinematic performances and muscle activations, underlying improvements in muscle function and strength, in response to upper arm training of patients with congenital or acquired brain injuries, are still poorly understood. One of the most interesting features of a robotmediated therapy is the ability to quantify the performance of the rehabilitation tasks proposed to the patient. Although...
Motor synergies have been investigated since the 1980s as a simplifying paradigm of motor control by the nervous system. In particular, it is believed that they allow control of the highly redundant kinematic chain of the human hand by the central nervous system. Whereas so far the focus has been on kinematic synergies, that is common patterns in the motion of the hand and fingers, we hereby also...
