Immediate effects of a controllable knee ankle foot orthosis for functional compensation of gait in patients with proximal leg weakness
Application of intermittent control of the knee joint stiffness in a knee ankle foot orthosis (KAFO) during gait is proposed. The approach combines inertial sensors and an actuator system in order to apply com...

Does Anode Position and Electrode Impedance Affect Muscle Selectivity in Upper Limb sFES?
Muscle selectivity during sFES in upper limb is an issue because of the presence of the “overflow” phenomenon. Surface electrodes array can augment muscle selectivity by generating an irregular electric field ...

Open AccessA neuroprosthesis for tremor management through the control of muscle co-contraction
Pathological tremor is the most prevalent movement disorder. Current treatments do not attain a significant tremor reduction in a large proportion of patients, which makes tremor a major cause of loss of quali...

Detection of Common Synaptic Inputs Shared by Populations of Motor Neurons Innervating Different Muscles: Methodology and Considerations for Neuroprosthetic Treatment of Tremor
A large proportion of tremor patients do not benefit from any treatment. This is partly motivated by the fact that current therapies may not be sufficiently specific because the pathophysiology of each type of...

Open AccessAdvances in selective activation of muscles for non-invasive motor neuroprostheses
Non-invasive neuroprosthetic (NP) technologies for movement compensation and rehabilitation remain with challenges for their clinical application. Two of those major challenges are selective activation of musc...

Neural Control of Muscles in Tremor Patients
Essential tremor and Parkinson’s disease cause abnormal oscillatory activity in a variety of brain structures that is transmitted to spinal motoneurons and generates tremor. Because the motoneuron pool integra...
