چکیده
Understanding the kinematics of the carpus is essential to the understanding and treatment of wrist pathologies. However, accurate measurement of the kinematics of the carpal bones is difficult because they are small bones undergoing complex movements of small amplitudes. As a result, to date, there is no clear consensus on carpal kinematics. Moreover, most studies only investigate single rotations of the wrist, whereas functional motions involve combined rotations. The present paper presents a novel method to reproduce functional wrist motions measured in vivo on cadaveric specimens, while at the same time measuring the kinematics of the carpal bones using K-wires. Results showed good accuracy (1.0 to 2.6°) of movement reproduction and kinematics measurement. Importantly the efforts at the wrist remained low during movement reproduction, further strengthening the validity of the method. Most carpal motion during wrist flexion-extension occurs at the radiocarpal level; while in ulnar deviation the motion is more equally shared between radiocarpal and midcarpal joints, and in radial deviation the motion happens mainly at the midcarpal joint. For all rotations the lunate exhibited more midcarpal motion compared to the scaphoid and triquetrum. For the functional motion studied (hammering), there was more midcarpal motion in wrist extension compared to pure wrist extension while radioulnar deviation patterns were similar to those observed in pure wrist radioulnar deviation. Finally, it was found that the amount of carpal rotations was proportional to global wrist rotations.

Most of our current understanding of brain function and dysfunction has its firm base in what is so elegantly called the 'anatomical substrate', i.e. the anatomical, histological, and histochemical domains within the large knowledge envelope called 'neuroscience' that further includes physiological, pharmacological, neurochemical, behavioral, genetical and clinical domains. This review focuses ...

The Elaborated Intrusion (EI) theory of desire posits that visual imagery plays a key role in craving. We report a series of experiments testing this hypothesis in a drug addiction context. Experiment 1 showed that a mental visual imagery task with neutral content reduced cigarette craving in abstaining smokers, but that an equivalent auditory task did not. The effect of visual imagery was repl...
