We developed a wrist model using neural networks based on Hammerstein cascade. The model can predict the wrist angle while stimulating by different pulse widths of the stimulation. It consists of neural networks to represent the muscle recruitment properties, and a linear dynamical system to represent the time variation. Simulation results on actual measurements were compared with the output fr...
BACKGROUND Public health research on sedentary behavior (SB) in youth has heavily relied on accelerometers. However, it has been limited by the lack of consensus on the most accurate accelerometer cut-points as well as by unknown effects caused by accelerometer position (wrist vs. hip) and output (single axis vs. multiple axes). The present study systematically evaluates classification accuracy...
Wrist fracture is not only one of the most common osteoporotic fractures but also a predictor of future fractures at other sites. Wrist bone mineral density (BMD) is an important determinant of wrist fracture risk, with high heritability. Specific genes underlying wrist BMD variation are largely unknown. Most published genome-wide association studies (GWASs) have focused only on a few top-ranki...
BACKGROUND Although self-assessment questionnaires for the wrist joint are numerous, most validation studies focus on a specific pathology and patient collectives. In addition the available questionnaires focus on subjective parameters such as pain, usual and specific activities but the range of motion (ROM) as an essential objective parameter in wrist disorders is rarely considered. Therefore ...
Flow-mediated dilatation (FMD) of the brachial artery assessed by high-resolution ultrasound is widely used to measure endothelial function. However, the technique is not standardized, with different groups using occlusion of either the wrist or the upper arm to induce increased blood flow. The validity of the test as a marker of endothelial function rests on the assumption that the dilatation ...
BACKGROUND the complex motions of the wrist are described in terms of four anatomical directions that are accomplished through the multiple articulations of the carpus. With minimal tendinous insertions, the carpus is primarily a passive structure. This emphasizes the importance of its mechanical properties, which few studies have examined to date. The purpose of the present study was to determ...
THE PATIENT A 37-year-old man injured his right wrist in a motor vehicle collision. In the emergency department he had severe wrist pain and median nerve paresthesia. Wrist radiographs identified a dorsal perilunate dislocation (PLD) with the carpus dislocated dorsally and the lunate tilted volar but still located in the lunate fossa. Post-reduction computed tomography scan confirmed no fractures.
Hundred people were examined for piezogenic papules (cutaneous hernia). Of these 80 had pedal papules, 86 wrist papules and 74 both pedal and wrist papules. Most of these papules were bilateral and multiple. All cases examined were painless. Biopsy showed fragmentation of dermal elastic tissue and herniation of subcutaneous fat into the dermis. Histology was similar for both pedal and wrist pap...
