Summary: Information about hand position is provided by multisensory signals, which may not always be perfectly aligned. When there are discrepancies between visual and proprioceptive signals, processes such as multisensory integration, sensory recalibration, and motor adaptation are engaged to adjust perception and behavioral responses. We investigated the short-term dependence of these processes on multisensory discrepancies in a visuomotor task, and found that integration of discrepant signals is immediate and independent of previous trials, but the strength of integration depends on the context.

Summary: This study proposes a method to improve the accuracy of optical heart rate estimation in smartwatches by using wrist surface electromyogram (EMG) and accelerometer (ACC) with spectrum subtraction algorithms. The analysis of data from nine subjects shows that wrist EMG has a strong correlation with motion artifacts in the photoplethysmography (PPG) signal and provides additional information compared to ACC data.

Summary: Research on intention recognition of lower limb rehabilitation robot requires consideration of normal movement intentions before improving models to recognize patient intentions. A projected recurrent neural network (PRNN) model has been proposed to address convergence speed limitations of traditional RNN models, showing successful application in experimental intention recognition of lower limb movements.

Summary: The study found that there was no significant difference in proprioceptive accuracy between simple uni-joint and more complex multi-joint arm-raising movement patterns when discriminating between different overhead targets. Additionally, participants who performed well with one pattern tended to perform well with the other pattern as well. However, discrimination accuracy decreased as the overhead target movement extent increased.

Summary: SE-AssessWrist extends the capabilities of robotic devices by including complete wrist range of motion assessment and stiffness evaluation. Experimental validation showed that the device achieves desired range of motion and provides sufficient control performance for wrist biomechanical assessment. Measurements revealed that the axis of greatest range of motion and least stiffness were oblique to anatomical axes and approximately parallel to each other.

Summary: The study found that cerebellar patients can improve motor performance through practice, but the impact of different types of feedback on learning remains unclear. After training, differences in gray matter volume changes were observed between the control group and cerebellar patients, indicating that compensatory remodeling manifests differently in different brain regions.

Summary: This article presents an approach for detecting lies based on pupil dilation, which is used by robots to assess the trustworthiness of their human partners in an ecological human-robot interaction. The study demonstrates the validity of the approach through an experiment where the iCub humanoid robot detects deceptive behavior in real-time. Additionally, the article explores the use of machine learning models to improve lie detection performances for both known and novel partners.

Summary: This multicenter study tested the ability of the CCAS-Scale to diagnose CCAS in individual patients with common forms of hereditary ataxia. The results showed that the CCAS-Scale had limited ability to diagnose CCAS in individual patients, especially in milder cases with a substantial number of false-positive results. SCA3 patients performed the worst, with lower scores compared to SCA6 and FRDA patients.

Summary: The design of prosthetic controllers using neurophysiological signals remains a significant challenge for bioengineers. Existing electromyographic (EMG) continuous pattern recognition controllers rely on assumptions of stable EMG patterns, which we challenge. We propose an algorithm that decodes wrist and hand movements based on transient EMG signals. Our offline evaluations show promising results with non-amputees achieving a median accuracy of around 96%, while amputees achieved a median accuracy of around 89%. Further assessments with domain-adaptation strategies may be needed for amputees. Overall, our results support the hypothesis that decoding transient EMG signals can be a viable pattern recognition strategy for prosthetic controllers.

Summary: Restoring the function of a missing hand remains a major challenge for bioengineers. Recent advancements in myoelectric hand prostheses and their controllers have been significant, but the wrist joint is often overlooked. We propose a design for a prosthetic wrist that can transition between compliant and stiff modes, providing flexibility for reaching and stability during manipulation.

Summary: Determining the spatial relation between objects and our location is crucial for survival. The vestibular system plays a role in localizing visual targets in the surrounding environment, suggesting a functional interaction between vestibular and visual signals. Artificial disruption of vestibular cues impairs the accuracy and precision of locating visual targets, highlighting the importance of the vestibular system in encoding spatial relationships.

Summary: Recent studies have shown that dimensionality reduction techniques can simplify the description of human upper limb motion and be applied to robotic joints. A structured methodology using time warping and task segmentation was proposed to align and process upper limb kinematic data. Functional principal component analysis (fPCA) extracted patterns of wrist motion, with three fPCs explaining over 85% of the variance. Wrist trajectories in the reaching phase were highly correlated among participants and more so than in the manipulation phase, which has implications for robotic control and therapy development.
