Summary: The study explores the use of virtual reality and serious games in investigating visuomotor adaptation capabilities for motor disorders. It presents a framework that uses a full-body moving avatar in a VR environment to assess participants' performance in locomotion tasks. The authors emphasize the potential of this framework as a quantitative tool for evaluating motor and cognitive impairments and suggest future research on specific disorders.

Summary: This study aimed to test the validity of visual representations of food products in virtual reality by comparing descriptions of actual vs. virtual cookies. The results showed that descriptions of virtual cookies were close to descriptions of the actual cookies. Differences in the weight of brightness and color contrast in the perceptual space of actual and virtual products were observed, which may be due to software-setting configurations that could be optimized for a better match.

Summary: Decades of research have found that absolute egocentric distance is underestimated in virtual environments (VEs) compared to the real world. This has implications for applications requiring accurate perception of absolute scale. Fortunately, this underperception can be reduced by certain factors, making perception in VEs closer to that of the real world. This article examines these factors as two categories: observer's experience and display technology characteristics, in order to understand how the scale of virtual spaces is calibrated.

Summary: This study found that sensitivity to visual cues predicts the severity of motion sickness symptoms. The research also explored another reported source of variability in motion sickness severity in VR, sex, but found little support for it. Previously reported sex differences in motion sickness severity in VR might be due to poor personalization of VR displays.

Summary: In this study, a VR remote collaboration system using motion capture technology is proposed to enhance immersion by synchronizing user and virtual character operations. Experimental results demonstrate that the implemented technique of synchronizing character size according to user's body reduces the error in the virtual environment.

Summary: This study proposes two methods for describing lowerlimb joint kinematics using low-budget hardware accessories for VR headsets. The proposed system allows for the collection of complete kinematic data of the lower limb with comparable repeatability to advanced optoelectronic motion capture systems. The tools enable cost-effective analysis of kinematics in accordance with biomechanical research protocols and consistent with clinical practice.

Summary: The relationship between perceived visual motion and vection in Virtual Reality was explored in experiments using colourful illusions. It was found that illusions perceived as moving more elicited stronger experiences of both cybersickness and vection. Head movements were not related to stimulus properties, suggesting that the motion signal elicited by illusions may not be strong enough to cause postural instability. Dizziness was identified as a possible link between cybersickness, vection, and head movements.

Summary: This study investigates the role of low-frequency oscillations in 3D perception with depth cues, using visual stimuli presented by virtual reality technology. The findings suggest that low-frequency delta and theta bands are specific to stereoscopic vision and show increased functional connectivity in cortical areas related to visual pathways.

Summary: The prevailing scientific paradigm posits matter as primary, while an alternative view sees consciousness as a fundamental force in nature. Virtual reality can provide insights into the primacy of consciousness, although its implications for physical reality and the emergence of consciousness from brain function remain uncertain.

Summary: This study investigates the influence of available response time, temporal certainty, and physical certainty on anticipatory and reactive locomotor strategies. The results indicate that individuals do not develop perturbation-specific feedforward strategies despite having information about the timing and direction of upcoming perturbations. Instead, they rely on feedback control to recover normal gait, with physical certainty making the feedback controller more efficient and enabling faster recovery.

Summary: This scoping review examined the use of anti-gravity treadmills and their effects on lower-limb motor functions in children and adolescents with locomotor impairments. The included studies reported improvements in muscle strength, balance, gait parameters, and walking endurance. A more precise and comprehensive description of anti-gravity training protocols is needed.

Summary: In the presence of experimental low back pain, the motor networks involved in the control of back muscles at the spinal, subcortical, and cortical levels were not modified. However, once the pain disappeared, a reduction in motoneuronal excitability was observed without change in corticospinal and vestibulospinal excitability, suggesting a reduction in descending drive. Experimental low back pain may elicit long-term plasticity even after pain extinction.

Summary: The aim of this paper is to review methods employed to reduce the contamination of single channel EMG signals. Specifically, we focus on methods which enable a full reconstruction of the EMG signal without loss of information. This includes subtraction methods used in the time domain, denoising methods performed after the signal decomposition and hybrid approaches that combine multiple methods.

Summary: This study aimed to assess the cerebral response and motor performance during a sensorimotor conflict in people with fibromyalgia. The results showed that individuals with fibromyalgia exhibited a stronger conflict detection during sensorimotor conflicts compared to pain-free controls. However, there were no significant differences in motor performance between the two groups.

Summary: The aim of this study is to assess the reliability and validity of the Assisting Hand Assessment (AHA) scoring grid in unstandardized activities of daily living (ADLs) for adults with cerebral palsy (CP). The results indicate the potential of using an observation-based scoring grid to assess bimanual performance in CP patients, but further research on psychometric properties is needed.

Summary: This work presents a system for measuring and analyzing motion using a portable electronic device and a flexible fiber sensor. The system includes a new sensor interface circuit that measures the impedance of the fiber, which is composed of multi-walled carbon nanotubes and polydimethylsiloxane elastomer. The measured data is transmitted to a laptop via Bluetooth, allowing for easy integration into a smart garment. The system was assessed on a robotic arm and through various exercises on 5 participants, showing good measurement performance and accuracy.
