Modern VR technologies can further enhance usability, allowing the participant to seamlessly interact with VR environment with bare hands, without need of external tracking systems and complex setups. In children neurorheabilitation engagement can promote motivation and attention to the exercise, two key elements for effectiveness of the rehabilitation process. In this work we developed a rehabilitation system composed of three serious games in immersive VR, with motor exercises targeting the upper limb and trunk in children with Cerebral Palsy. The participant plays in the role of a wizard apprentice, called to cast spells, to prepare potions and to ride a magic eagle. These game scenarios involve coordinated motor functions related to trajectory tracking, pick-and-place with prono-supination, and trunk balance. The presented pilot study (12 CP children, 24 sessions), focuses on the feasibility assessment of the rehabilitation method, then, it allows a more in depth analysis on the adaptation and progress of the exercise parameters through data recorded during the whole treatment. The study shows that immersive VR games are a feasible approach in rehabilitation procedures, with positive results regarding acceptability, retention, adherence to the planned exercises and absence of adverse effects in the long-term use. They also show promising results in improvements of motor functions, although a direct comparison with a control group was not included in the study.","PeriodicalId":13419,"journal":{"name":"IEEE Transactions on Neural Systems and Rehabilitation Engineering","volume":"33 ","pages":"3105-3115"},"PeriodicalIF":5.2,"publicationDate":"2025-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11109068","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144784245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This cumbersome recalibration procedure would make it difficult to use BCIs daily. We aim to address the daily recalibration issue by examining across-day variations of the BCI performance and proposing a method to avoid daily recalibration. To this end, we implemented a P300-based BCI system designed to control a home appliance over five days. We first examined how the BCI performance varied across days with or without daily recalibration. On each day, the BCIs were tested using recalibration-based and recalibration-free decoders (RB and RF), with an RB or an RF decoder being built on the training data on each day or those on the first day, respectively. Using the RF decoder resulted in lower BCI performance on subsequent days compared to the RB decoder. Then, we developed a method to extract daily common ERP patterns from observed ERP signals using the sparse dictionary learning algorithm. We applied this method to the RF decoder and retested the BCI performance over days. Using the proposed method improved the RF decoder performance on subsequent days; the performance was closer to the level of the RB decoder compared to the original RF decoder. The method may provide a novel approach to addressing the daily-recalibration issue for P300-based BCIs, which is essential to implementing BCIs into daily life.","PeriodicalId":13419,"journal":{"name":"IEEE Transactions on Neural Systems and Rehabilitation Engineering","volume":"33 ","pages":"2977-2987"},"PeriodicalIF":5.2,"publicationDate":"2025-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11105461","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144759994","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study introduces Rotational Power (RP), which is a new metric derived from a single thigh-worn accelerometer, that can serve as a surrogate for body-mass normalized mechanical power during sit-to-stand (SI-ST) and stand-to-sit (ST-SI) transitions. We validate the metric both analytically and clinically in seventeen PwMS who performed a 30CST while instrumented with an accelerometer and a motion-capture system for reference.

However, NFT combined with motor imagery-based brain-computer interface (MI-BCI) faces challenges such as mental fatigue and non-personalized training strategies. Therefore, we proposed an adaptive NFT based on a VR game that simulates real-life motor tasks to improve training efficiency. We conducted a detailed comparative analysis of the efficiency of the VR-based NFT and traditional Graz-based NFT. Forty-eight healthy subjects were randomly assigned to five groups and underwent various NFT protocols. Among them, the subjects in the four experimental groups were required to perform the NFT three times over five days, including virtual or real scenarios, as well as unilateral or bilateral hands training. We evaluated training effects by analyzing EEG features and classification performance, while online recognition duration served as the primary measure for assessing the adaptive NFT strategy. EEG analysis showed that VR-based NFT significantly enhanced the Event-related desynchronization (ERD) activations in the sensorimotor cortices over five days. The VR-based NFT group achieved a classification accuracy of 81.85%, representing a 10.14% improvement from baseline, which exceeded the 6.43% increase observed in the Graz-based NFT group. Furthermore, implementing the adaptive NFT strategy reduced the mean task duration by over 30% compared to the fixed-time training protocol. The results demonstrated that the adaptive MI-BCI-based NFT in a VR game achieves superior training outcomes while reducing training duration. These findings suggest the promising potential for applying MI-BCI NFT with VR games in motor rehabilitation following a stroke.","PeriodicalId":13419,"journal":{"name":"IEEE Transactions on Neural Systems and Rehabilitation Engineering","volume":"33 ","pages":"2956-2966"},"PeriodicalIF":5.2,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11097354","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144730097","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While speech-based assistant systems rely on wake-word detection (e.g., “Hey Siri”), BCI-based communication system must capture imagined onset from EEG signals to turn on the ‘brain switch’ to further convey user’s imagined command. Nevertheless, the absence of reliable ground truth for the endogenous paradigm adds to the complexity to train the model to capture exact onset from continuous EEG. To address these issues, we introduce a multi-receptive field convolutional neural network, designed to capture speech and idle states based on behaviorally-aligned EEG features. We propose a voice-based ground truth alignment method with voting strategy that aims to synchronize imagined speech with overt speech onset and offset, providing a structured approach for capturing speech events in asynchronous BCI systems. Furthermore, spectral and phonological analyses revealed that beta and alpha bands, as well as syllable count, appear to influence speech state discriminability. Evaluations on imagined and overt speech tasks, including pseudo-online experiments, demonstrate the potential to enhance asynchronous BCI systems, supporting real-time communication for both healthy and impaired individuals.","PeriodicalId":13419,"journal":{"name":"IEEE Transactions on Neural Systems and Rehabilitation Engineering","volume":"33 ","pages":"2904-2914"},"PeriodicalIF":5.2,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11095808","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144707387","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Forty-two participants completed the experiment that included assessments of upper-limb motor function and cognitive function followed by simulated rehabilitation interaction sessions, where the FTF interaction was the first, followed by CT and SRAT interactions in randomized order. Participants completed surveys on their impression and experience receiving simulated care in each mode. Survey responses were analyzed using descriptive statistics and regression methods.

However, decoding of the attended speaker’s precise direction is desired. Existing approaches often underutilize spatial audio information, resulting in suboptimal performance. In this paper, we address this limitation by leveraging a recent dataset containing two concurrent speakers at two of 14 possible directions. We demonstrate that models relying solely on EEG yield limited decoding accuracy in leave-one-out settings. To enhance performance, we propose to integrate spatial spectra as an additional input. We evaluate three model architectures, namely CNN, LSM-CNN, and Deformer, under two strategies for utilizing spatial information: all-in-one (end-to-end) and pairwise (two-stage) decoding. While all-in-one decoders directly take dual-modal inputs and output the attended direction, pairwise decoders first leverage spatial spectra to decode the competing pairs, and then a specific model is used to decode the attended direction. Our proposed all-in-one Sp-EEG-Deformer model achieves 14-class decoding accuracies of 55.35% and 57.19% in leave-one-subject-out and leave-one-trial-out scenarios, respectively, using 1-second decision windows (chance level: 50%, indicating random guessing). Meanwhile, the pairwise Sp-EEG-Deformer decoder achieves a 14-class decoding accuracy of 63.62% (10 s). Our experiments reveal that spatial spectra are particularly effective at reducing the 14-class problem into a binary one. On the other hand, EEG features are more discriminative and play a crucial role in precisely identifying the final attended direction within this reduced 2-class set. These results highlight the effectiveness of our proposed dual-modal directional decoding strategies.","PeriodicalId":13419,"journal":{"name":"IEEE Transactions on Neural Systems and Rehabilitation Engineering","volume":"33 ","pages":"2892-2903"},"PeriodicalIF":5.2,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11091336","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144698359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
