A distinction is thus drawn between “dynamic” instability, visible on X-ray only under certain conditions of stress, such as tight fist, and “static” instability, with permanent diastasis between the scaphoid and lunate bones, with severe and often fixed displacement. Static instability often ...
A pulse wave sensor includes a detecting element and a sensor body. The pulse wave sensor is worn on the back side of a user's wrist corresponding to the back of the user's hand. The detecting element
We have used a small, computer run, hand-held system that generates vibration in the bone under examination, and then captures generated vibration signals by a piezoelectric sensor, which then are analyzed by applying signal processing methods. Various technological systems in both industry and medici...
a complete hand function [1]. A deep knowledge of wrist contact forces is fundamental for different reasons: evaluating the effects of treatment, designing better treatments (e.g., implants, rehabilitation regimens), optimizing performance, and obtaining clues to the pathogenesis of the disease [2...
The hand, with its 27 bones of the palm skeleton and the fingers, qualifies as the most complicated osteoarticular segment of the human body. This most complex articulation includes the 8 carpal bones displayed in two transversal rows forming the wrist, the 5 metacarpal bones, followed by the...
