Extended reality to assess post-stroke manual dexterity: contrasts between the classic box and block test, immersive virtual reality with controllers, with hand-tracking, and mixed-reality tests.

Background: Recent technological advancements present promising opportunities to enhance the frequency and objectivity of functional assessments, aligning with recent stroke rehabilitation guidelines. Within this framework, we designed and adapted different manual dexterity tests in extended reality (XR), using immersive virtual reality (VR) with controllers (BBT-VR-C), immersive VR with hand-tracking (BBT-VR-HT), and mixed-reality (MD-MR).

Objective: This study primarily aimed to assess and compare the validity of the BBT-VR-C, BBT-VR-HT and MD-MR to assess post-stroke manual dexterity.

A feature and conjunction visual search immersive virtual reality serious game for measuring spatial and distractor inhibition attention using response time and action kinematics.

Background: Treisman (1980) proposed that visual-spatial attention to targets presented with distractors involves parallel and serial cognition. When the target is different from distractors by a single feature, the number of distractors does not influence search speed (parallel). However, when the target is different from the distractor by a conjunction of features, increased numbers of distractors increase task difficulty (serial).

Performing a shortened version of the Action Research Arm Test in immersive virtual reality to assess post-stroke upper limb activity.

Background: To plan treatment and measure post-stroke recovery, frequent and time-bounded functional assessments are recommended. With increasing needs for neurorehabilitation advances, new technology based methods, such as virtual reality (VR) have emerged. Here, we developed an immersive VR version of the Action Research Arm Test (ARAT-VR) to complement neurorehabilitation.

Concurrent validity of an immersive virtual reality version of the Box and Block Test to assess manual dexterity among patients with stroke.

Background: After a stroke, experts recommend regular monitoring and kinematic assessments of patients to objectively measure motor recovery. With the rise of new technologies and increasing needs for neurorehabilitation, an interest in virtual reality has emerged. In this context, we have developed an immersive virtual reality version of the Box and Block Test (BBT-VR).

The Cognitive-Vestibular Compensation Hypothesis: How Cognitive Impairments Might Be the Cost of Coping With Compensation.

Previous research in vestibular cognition has clearly demonstrated a link between the vestibular system and several cognitive and emotional functions. However, the most coherent results supporting this link come from rodent models and healthy human participants artificial stimulation models. Human research with vestibular-damaged patients shows much more variability in the observed results, mostly because of the heterogeneity of vestibular loss (VL), and the interindividual differences in the natural vestibular compensation process.

The Visuo-Spatial Abilities Diagnosis (VSAD) test: Evaluating the potential cognitive difficulties of children with vestibular impairment through a new tablet-based computerized test battery.

Recent data collected on adult patients with vestibular loss (VL) tend to demonstrate possible cognitive impairments in visuospatial working memory, mental rotation, selective attention, and space orientation. However, the neuropsychological profile of children with VL remains largely under-investigated in the scientific literature. Although previous research has shown that children with VL may experience some degree of delayed motor development, it is not yet clear if VL could also lead to specific delayed cognitive development.

Action representation deficits in adolescents with developmental dyslexia.

Developmental dyslexia (DD), a severe and frequent disorder of reading acquisition, is characterized by a diversity of cognitive and motor deficits whose interactions still remain under debate. Although deficits in the automatization of sensorimotor control have been highlighted, internal action representation allowing prediction has never before been investigated. In this study, we considered action representation of 18 adolescents with pure DD and 18 age-matched typical readers.

Neuropsychological profiles of children with vestibular loss.

Background: The impact of vestibular loss (VL) on cognition has been previously studied in experimental animal, human and adult patient studies showing links between VL, and cognitive impairments in space orientation, working memory, mental rotation and selective attention. However, few studies have been conducted on children with VL.

Objective: We investigated for the first time, the impact of a VL on children's cognition.

Validation of a robot serious game assessment protocol for upper limb motor impairment in children with cerebral palsy.

Background: The ROBiGAME project aims to implement serious games on robots to rehabilitate upper limb (UL) motor function in children with cerebral palsy (CP). Serious game characteristics (target position, level of assistance/resistance, level of force) are typically adapted based on the child's assessment before and continuously during the game (measuring UL working area, kinematics and muscle strength).

Objective: This study developed an UL robotic motor assessment protocol to configure the serious game.

Action dual tasks reveal differential effects of visual imagery perspectives on motor performance.

Imagery research has identified two main visual perspectives, external visual imagery (EVI, third person) and internal visual imagery (IVI, first person). Based upon findings from brain imaging literature showing that different neural substrates are recruited for IVI and EVI perspectives, and that IVI activates motor system brain areas, we hypothesised that a concurrent action dual task would cause greater interference in performance for IVI than EVI. In a first experiment, participants were allocated to either an IVI or an EVI group, and were tasked with moving an onscreen marker towards a target in three blocked conditions: imagery, imagery with a concurrent motor dual-task of sequencing, and a math control.

Does observation of a disabled child's action moderate action execution? Implication for the use of Action Observation Therapy for patient rehabilitation.

Background: Research investigating action observation-execution priming has mainly manipulated congruent versus incongruent action, and aspects of action expertise/capability. More specifically, the literature suggests enhanced performance priming following action observation by actors closely matched to participant expertise. The aim of the present study was to extend the understanding of action expertise effects by investigating action priming in healthy participants after observing a mild hemiparetic child actor versus a neurologically healthy child actor.

The development of a new questionnaire for cognitive complaints in vertigo: the Neuropsychological Vertigo Inventory (NVI).

Vertigo patients frequently complain of emotional and associated cognitive problems, yet currently, there is no satisfactory questionnaire to measure these associated problems. In the present paper, we propose a new internet-based Neuropsychological Vertigo Inventory (NVI; French) that evaluates attention, memory, emotion, space perception, time perception, vision, and motor abilities. The questionnaire was created using four steps: (1) open interviews with patients suffering from vertigo; (2) semi-structured interviews with an analysis grid to quantify and define the various cognitive and emotional problems reported by the patients; (3) a first version of an internet questionnaire tested on 108 vertigo participants; and (4) the selection of subscale items using principal component analyses (PCA).

Performance improvements from imagery: evidence that internal visual imagery is superior to external visual imagery for slalom performance.

We report three experiments investigating the hypothesis that use of internal visual imagery (IVI) would be superior to external visual imagery (EVI) for the performance of different slalom-based motor tasks. In Experiment 1, three groups of participants (IVI, EVI, and a control group) performed a driving-simulation slalom task. The IVI group achieved significantly quicker lap times than EVI and the control group.

Sport concussion knowledge in the UK general public.

This is the first study to assess sport concussion knowledge and the effect of sport concussion self-report on knowledge in the UK general public. In the online survey, participants (n = 227) stated personal sport concussion history, injury indicators, and rated 26 injury statements for truthfulness using definite (true, false) or non-definite (probably true, probably false) response options. As anticipated, knowledge was limited.

Automatic priming of grip force following action observation.

Research shows that action observation can prime execution. Evidence for this comes from experiments that show that action observation influenced temporal (e.g.
