Wrist orthosis (11) having a supporting shell (10) that is open in the radial direction for receiving the distal forearm area and having a volar hand support (29
Studies of this type assume a peculiar importance, considering the need to develop devices that adapt to the anatomy of hand/wrist users. In this context, the understanding of human anthropometry, as well as its application in the design of medical rehabilitation devices for the wrist, ...
On the other hand, active-assist devices assist the users with “extra strength” while they are actively performing a rehabilitation exercise, by compensating for muscular/joint weakness. In 2012, Pehilvan et al. developed “Rice Wrist-S” for wrist rehabilitation after spinal cord injury and ...
The glove is worn on the hand, while the strap is placed on the forearm. The actuation system consists of five muscle‑like actuators (SMA coil springs). Three of these actuators are placed over the back of the hand, and the remaining two are over the palm. The actuators are activated...
Figure 1c shows the experimental diagram. Before the experiment, to keep the force of each wrist movement constant, the hand position of each subject was recorded when the wrist reached the maximum voluntary contraction force under the WF and WE movements. To ensure that the subjects can ...
as well as information on how these forces can be changed via correction of the bony anatomy are not available to the surgeon in clinical routine. The forces acting on the joint or the prosthesis and the way in which transfer this load to the bone also play an essential role in the long...
The anatomy references were derived from 3D magnetic resonance (MR) image slices and segmented for several tissue types. Finally, several models were derived from the tissue-segmented anatomy references by a proposed voxel-based Monte Carlo photon propagation system. The proposed Monte Carlo photon ...
On the other hand, ultrasound imaging is broadly accepted due to its non-invasiveness, real-time imaging, non-ionization, and cost-effectiveness. With these advantages, several measurements were performed to utilize ultrasound images to detect the pathological changes of the MN in the wrist tissues...
