Sensory weighting of position and force feedback during pinching

Human hands are complex biomechanical systems that allow for dexterous tasks with many degrees of freedom. Coordination of the fingers is essential for many activities of daily living and involves integrating sensory signals. During this sensory integration, the central nervous system deals with the uncertainty of sensory signals. When...

Design of a power-assistance system for body-powered hand-prostheses

Body-powered hand prostheses are characterized by low weight and low cost compared to externally powered prostheses. They also provide force and position feedback, allowing for accurate and fast position and force control of the prosthesis. Body-powered hand prostheses are often rejected on the basis of low efficiency. The high forces needed to...

The intermuscular 3–7 Hz drive is not affected by distal proprioceptive input in myoclonus-dystonia

In dystonia, both sensory malfunctioning and an abnormal intermuscular low-frequency drive of 3–7 Hz have been found, although cause and eVect are unknown. It is hypothesized that sensory processing is primarily disturbed and induces this drive. Accordingly, experimenter-controlled sensory input should be able to inXuence the frequency of the...
