Article Abstract
Surface electromyography (sEMG) signals reflect spinal motor neuron activities, and can be used as intuitive inputs for human-machine interaction (HMI) via movement intent recognition. The motor neuron potentials of far-field (wrist) and near-field (forearm) decomposed from high-density (HD) sEMG prospectively provide robust neural drives for HMI, which is a challenging research hotspot. However, there are no publicly available databases that include HD sEMG signals of forearm-wrist (FW) muscles, and hand kinematics (KIN). This paper presents the HD-FW KIN dataset that comprises HD 448-channel sEMG arrays distributed on forearm and wrist with simultaneously recording of finger joint angles and finger flexion forces. This dataset contains muscle activities of 21 subjects while performing 20 hand gestures, and 9 individual or combined finger flexion under two force levels. The usabilities of HD sEMG for hand gesture recognition, finger angle and force prediction were validated. The proposed database allows a comprehensive extraction of the neural drive from forearm and wrist, providing neural interfaces for the development of advanced prosthetic hand and wrist-worn consumer electronics.

Effects of sand, asphalt, and a three degrees hind toe or heel elevation on equine cervical and thoracolumbosacral kinematics at walk and trot.

Background: Effects of ground surface and hoof angles on equine cervical and thoracolumbosacral kinematics are poorly understood. However, the equine cervical and thoracolumbosacral areas present frequent lesions and he management of factors that might improve treatment and rehabilitation outcomes, such as ground surface and hoof angles, requires more investigation.
Aims: Our objectives were to determine the influence of ground surface (asphalt versus sand) and a 3 degrees hind toe or heel elevation on cervical and thoracolumbosacral kinematics during walking and trotting.
A case report on the reconstruction of arson, corpse burning, and postmortem relocation based on burn trace characteristics.

Forensic identification at fire scenes faces three core challenges: distinguishing cause of death (antemortem burning versus postmortem corpse burning), reconstructing criminal behavior (arson versus accident), and preserving evidence (thermal destruction versus artificial tampering). This case study systematically demonstrates the application value of burn trace characteristics in arson investigation through a typical intentional homicide and corpse burning case. Based on a three-dimensional analytical framework of human burn-behavioral characteristics, a systematic pathway incorporating reconstruction of arson/corpse burning processes and identification of body relocation behavior was established.

However, collecting robust biomechanics hand data is a time intensive process leading to a lack of widely available datasets. To address this issue the biomechanics hand modeling database (BHaM) was made as a collection of experimental data to aid the development, testing, and validation of musculoskeletal models and simulations.

The dexterity of the human hand is largely due to its multiple degrees of freedom. However, coordinating the movements of the ring and little fingers independently can be challenging because of the biomechanical and neurological interdependencies between them. This research presents a cascade control system based on fuzzy logic to manage the dynamic movements of these fingers within a simulated biomechanical model of a human hand.

Background: The use of reverse total shoulder arthroplasty (rTSA) has increased in recent years, thanks to its application versatility. Despite this increase, there exists a significant variability in postoperative functional internal rotation (fIR), affecting patients' daily life independence. Previous literature investigated patient-related, kinematical, and surgical parameters to understand the variability in fIR outcome.
