Prevotella copri transplantation promotes neurorehabilitation in a mouse model of traumatic brain injury.

BACKGROUND: The gut microbiota plays a critical role in regulating brain function through the microbiome-gut-brain axis (MGBA). Dysbiosis of the gut microbiota is associated with neurological impairment in Traumatic brain injury (TBI) patients. Our previous study found that TBI results in a decrease in the abundance of Prevotella copri (P. copri). P. copri has been shown to have antioxidant effects in various diseases. Meanwhile, guanosine (GUO) is a metabolite of intestinal microbiota that can alleviate oxidative stress after TBI by activating the PI3K/Akt pathway. In this study, we investigated the effect of P. copri transplantation on TBI and its relationship with GUO-PI3K/Akt pathway. METHODS: In this study, a controlled cortical impact (CCI) model was used to induce TBI in adult male C57BL/6J mice. Subsequently, P. copri was transplanted by intragastric gavage for 7 consecutive days. To investigate the effect of the GUO-PI3K/Akt pathway in P. copri transplantation therapy, guanosine (GUO) was administered 2 h after TBI for 7 consecutive days, and PI3K inhibitor (LY294002) was administered 30 min before TBI. Various techniques were used to assess the effects of these interventions, including quantitative PCR, neurological behavior tests, metabolite analysis, ELISA, Western blot analysis, immunofluorescence, Evans blue assays, transmission electron microscopy, FITC-dextran permeability assay, gastrointestinal transit assessment, and 16 S rDNA sequencing. RESULTS: P. copri abundance was significantly reduced after TBI. P. copri transplantation alleviated motor and cognitive deficits tested by the NSS, Morris's water maze and open field test. P. copri transplantation attenuated oxidative stress and blood-brain barrier damage and reduced neuronal apoptosis after TBI. In addition, P. copri transplantation resulted in the reshaping of the intestinal flora, improved gastrointestinal motility and intestinal permeability. Metabolomics and ELISA analysis revealed a significant increase in GUO levels in feces, serum and injured brain after P. copri transplantation. Furthermore, the expression of p-PI3K and p-Akt was found to be increased after P. copri transplantation and GUO treatment. Notably, PI3K inhibitor LY294002 treatment attenuated the observed improvements. CONCLUSIONS: We demonstrate for the first time that P. copri transplantation can improve GI functions and alter gut microbiota dysbiosis after TBI. Additionally, P. copri transplantation can ameliorate neurological deficits, possibly via the GUO-PI3K/Akt signaling pathway after TBI.

Integration of music-based game approaches with wearable devices for hand neurorehabilitation: a narrative review.

BACKGROUND: Restoring hand functionality is critical for fostering independence in individuals with neurological disorders. Various therapeutic approaches have emerged to address motor function restoration, with music-based therapies demonstrating notable advantages in enhancing neuroplasticity, an integral component of neurorehabilitation. Despite the positive effects observed, there remains a gap in the literature regarding implementing music treatments in neurorehabilitation, such as Neurologic Music Therapy (NMT), especially in conjunction with emerging fields like wearable devices and game-based therapies. METHODS: A literature search was conducted in various databases, including PubMed, Scopus, IEEE Xplore, and ACM Digital Library. The search was performed using a literature search methodology based on keywords. Information collected from the studies pertained to the approach used in music therapy, the design of the video games, and the types of wearable devices utilized. RESULTS: A total of 158 articles were found, including 39 from PubMed, 34 from IEEE Xplore, 48 from Scopus, 37 from ACM Digital Library, and 35 from other sources. Duplicate entries, of which there were 41, were eliminated. In the first screening phase, 152 papers were screened for title and abstract. Subsequently, 89 articles were removed if they contained at least one exclusion criterion. Sixteen studies were considered after 63 papers had their full texts verified. CONCLUSIONS: The convergence of NMT with emerging fields, such as gamification and wearable devices designed for hand functionality, not only expands therapeutic horizons but also lays the groundwork for innovative, personalized approaches to neurorehabilitation. However, challenges persist in effectively incorporating NMT into rehabilitation programs, potentially hindering its effectiveness.

Motor Imagery Performance through Embodied Digital Twins in a Virtual Reality-Enabled Brain-Computer Interface Environment.

This study introduces an innovative framework for neurological rehabilitation by integrating brain-computer interfaces (BCI) and virtual reality (VR) technologies with the customization of three-dimensional (3D) avatars. Traditional approaches to rehabilitation often fail to fully engage patients, primarily due to their inability to provide a deeply immersive and interactive experience. This research endeavors to fill this gap by utilizing motor imagery (MI) techniques, where participants visualize physical movements without actual execution. This method capitalizes on the brain's neural mechanisms, activating areas involved in movement execution when imagining movements, thereby facilitating the recovery process. The integration of VR's immersive capabilities with the precision of electroencephalography (EEG) to capture and interpret brain activity associated with imagined movements forms the core of this system. Digital Twins in the form of personalized 3D avatars are employed to significantly enhance the sense of immersion within the virtual environment. This heightened sense of embodiment is crucial for effective rehabilitation, aiming to bolster the connection between the patient and their virtual counterpart. By doing so, the system not only aims to improve motor imagery performance but also seeks to provide a more engaging and efficacious rehabilitation experience. Through the real-time application of BCI, the system allows for the direct translation of imagined movements into virtual actions performed by the 3D avatar, offering immediate feedback to the user. This feedback loop is essential for reinforcing the neural pathways involved in motor control and recovery. The ultimate goal of the developed system is to significantly enhance the effectiveness of motor imagery exercises by making them more interactive and responsive to the user's cognitive processes, thereby paving a new path in the field of neurological rehabilitation.

Immersive VR for upper-extremity rehabilitation in patients with neurological disorders: a scoping review.

BACKGROUND: Neurological disorders, such as stroke and chronic pain syndromes, profoundly impact independence and quality of life, especially when affecting upper extremity (UE) function. While conventional physical therapy has shown effectiveness in providing some neural recovery in affected individuals, there remains a need for improved interventions. Virtual reality (VR) has emerged as a promising technology-based approach for neurorehabilitation to make the patient's experience more enjoyable. Among VR-based rehabilitation paradigms, those based on fully immersive systems with headsets have gained significant attention due to their potential to enhance patient's engagement. METHODS: This scoping review aims to investigate the current state of research on the use of immersive VR for UE rehabilitation in individuals with neurological diseases, highlighting benefits and limitations. We identified thirteen relevant studies through comprehensive searches in Scopus, PubMed, and IEEE Xplore databases. Eligible studies incorporated immersive VR for UE rehabilitation in patients with neurological disorders and evaluated participants' neurological and motor functions before and after the intervention using clinical assessments. RESULTS: Most of the included studies reported improvements in the participants rehabilitation outcomes, suggesting that immersive VR represents a valuable tool for UE rehabilitation in individuals with neurological disorders. In addition, immersive VR-based interventions hold the potential for personalized and intensive training within a telerehabilitation framework. However, further studies with better design are needed for true comparison with traditional therapy. Also, the potential side effects associated with VR head-mounted displays, such as dizziness and nausea, warrant careful consideration in the development and implementation of VR-based rehabilitation programs. CONCLUSION: This review provides valuable insights into the application of immersive VR in UE rehabilitation, offering the foundation for future research and clinical practice. By leveraging immersive VR's potential, researchers and rehabilitation specialists can design more tailored and patient-centric rehabilitation strategies, ultimately improving the functional outcome and enhancing the quality of life of individuals with neurological diseases.

Effects of a respiratory and neurological rehabilitation treatment plan in post Covid-19 affected university students. Randomized clinical study.

BACKGROUND: COVID-19 demonstrated the possibility of neurological complications such as loss of sense of smell and taste, together with respiratory problems. Respiratory training and rehabilitation of neurological sequelae are essential to improve respiratory function and thus quality of life, and the aim of this study is to evaluate the efficacy of a pulmonary and neurological rehabilitation program. OBJECTIVES: To apply a treatment to reduce dyspnea, increase exertional capacity, increase vital capacity and respiratory muscle strength, together with an increase in olfactory and gustatory sensitivity in post-SARS-CoV-2 patients. METHODS: A randomised controlled experimental study was conducted in 220 patients with a medical diagnosis of COVID-19 and more than 5 months of evolution, dyspnoea or perceived fatigue, including olfactory and gustatory perception problems, of whom 200 patients completed the study. 100 patients were randomly assigned to the intervention group, consisting of an inspiratory training treatment plan (Powerbreathe Plus®) combined with aerobic exercise and olfactory gustatory treatment for 31 days, and 100 patients to the control group, for 31 days without any type of therapy. RESULTS: The study was conducted in post-Covid-19 patients for 5 months. Two hundred patients were divided into an intervention group (n = 100) and a control group (n = 100). The comparison between the groups showed significant differences in spirometric variables; forced vital capacity (p < .001; Eta2 (0.439); Mean: 0,6135), the ratio between both FEV1/FVC (p < 0.01; Eta2 (0.728); Mean:9,313), peak inspiratory pressure (p < 0.01; Eta2 (0.906); Mean:4,526); changes were observed in dyspnoea measured with the modified Borg scale (p < 0.01; Eta2 (0.811); Mean:1,481) and the modified Medical Research Council scale (p < 0.01; Eta2 (0.881); Mean: 0.777); finally, changes were found in neurological variables, in the questions of the Singapore Smell and Taste Questionnaire, How was your sense of smell after treatment? (p < 0.01; Eta2 (0.813); Mean: 1,721) and How is your sense of taste after treatment? (p < 0.01; Eta2 (0.898); Mean: 1,088). CONCLUSION: The implementation of a respiratory rehabilitation treatment plan with the Powerbreathe Plus® device, aerobic exercise and neurorehabilitation with olfactory and gustatory training, is a therapeutic option against respiratory and neurological sequelae in patients who have suffered such sequelae due to the SARS-CoV-2 virus.

Effectiveness of vestibular rehabilitation on postural balance in Parkinson's disease: a systematic review and meta-analysis of randomized controlled trials.

INTRODUCTION: Postural balance impairment can affect the quality of life of patients with Parkinson's disease. Previous studies have described connections of the vestibular system with postural functions, suggesting a potential participation of the basal ganglia in receiving vestibular stimuli. This systematic review aims to summarize the evidence on the effectiveness of vestibular rehabilitation on postural balance in patients with Parkinson's disease. METHODS: A systematic review was conducted using the electronic databases: PubMed, Embase, Scopus and PEDro. The study selection was independently conducted by two reviewers, and disagreements were evaluated by a third reviewer. The included studies had no restrictions on publication dates or languages and the last update occurred in July 2023. RESULTS: From the 485 studies found in the searches, only 3 studies were deemed eligible for the systematic review involving a total of 130 participants. The Berg Balance Scale was described as the tool for evaluation of postural balance in all studies. The meta-analysis showed statistically significant results in favor of vestibular rehabilitation (MD = 5.35; 95% CI = 2.39, 8.31; P < 0.001), regardless of the stage of Parkinson's disease. Although the effect size was suggested as a useful functional gain, the analysis was done with caution, as it only included 3 randomized controlled trials. The risk of bias using the RoB-2 was considered as being of "some concern" in all studies. Furthermore, the quality of the evidence based on the Grading of Recommendations Assessment Development and Evaluation system, produced by pooling the included studies was considered very low. CONCLUSION: Compared to other interventions, vestibular rehabilitation has potential to assist the postural balance of patients with Parkinson's disease. However, the very low quality of the evidence demonstrates uncertainty about the impact of this clinical practice. More robust studies are needed to confirm the benefits of this therapy in patients with Parkinson's disease. This study was prospectively registered in PROSPERO: CRD42020210185.

Paroxysmal sympathetic hyperactivity during neurorehabilitation for severe acquired brain injury: current Scandinavian practice and Delphi consensus recommendations.

OBJECTIVES: To document current practice and develop consensus recommendations for the assessment and treatment of paroxysmal sympathetic hyperactivity (PSH) during rehabilitation after severe acquired brain injury. DESIGN: Delphi consensus process with three rounds, based on the Guidance on Conducting and REporting DElphi Studies (CREDES) guidelines, led by three convenors (the authors) with an expert panel. Round 1 was exploratory, with consensus defined before round 2 as agreement of at least 75% of the panel. SETTING: A working group within the Nordic Network for Neurorehabilitation. PANEL PARTICIPANTS: Twenty specialist physicians, from Sweden (9 participants), Norway (7) and Denmark (4), all working clinically with patients with severe acquired brain injury and with current involvement in clinical decisions regarding PSH. RESULTS: Consensus was reached for 21 statements on terminology, assessment and principles for pharmacological and non-pharmacological treatment, including some guidance on specific drugs. From these, an algorithm to support clinical decisions at all stages of inpatient rehabilitation was created. CONCLUSIONS: Considerable consensus exists in the Nordic countries regarding principles for PSH assessment and treatment. An interdisciplinary approach is needed. Improved documentation and collation of data on treatment given during routine clinical practice are needed as a basis for improving care until sufficiently robust research exists to guide treatment choices.

Enhancing touch sensibility with sensory electrical stimulation and sensory retraining.

A large proportion of stroke survivors suffer from sensory loss, negatively impacting their independence, quality of life, and neurorehabilitation prognosis. Despite the high prevalence of somatosensory impairments, our understanding of somatosensory interventions such as sensory electrical stimulation (SES) in neurorehabilitation is limited. We aimed to study the effectiveness of SES combined with a sensory discrimination task in a well-controlled virtual environment in healthy participants, setting a foundation for its potential application in stroke rehabilitation. We employed electroencephalography (EEG) to gain a better understanding of the underlying neural mechanisms and dynamics associated with sensory training and SES. We conducted a single-session experiment with 26 healthy participants who explored a set of three visually identical virtual textures-haptically rendered by a robotic device and that differed in their spatial period-while physically guided by the robot to identify the odd texture. The experiment consisted of three phases: pre-intervention, intervention, and post-intervention. Half the participants received subthreshold whole-hand SES during the intervention, while the other half received sham stimulation. We evaluated changes in task performance-assessed by the probability of correct responses-before and after intervention and between groups. We also evaluated differences in the exploration behavior, e.g., scanning speed. EEG was employed to examine the effects of the intervention on brain activity, particularly in the alpha frequency band (8-13 Hz) associated with sensory processing. We found that participants in the SES group improved their task performance after intervention and their scanning speed during and after intervention, while the sham group did not improve their task performance. However, the differences in task performance improvements between groups only approached significance. Furthermore, we found that alpha power was sensitive to the effects of SES; participants in the stimulation group exhibited enhanced brain signals associated with improved touch sensitivity likely due to the effects of SES on the central nervous system, while the increase in alpha power for the sham group was less pronounced. Our findings suggest that SES enhances texture discrimination after training and has a positive effect on sensory-related brain areas. Further research involving brain-injured patients is needed to confirm the potential benefit of our solution in neurorehabilitation.

Neurorehabilitation across the Continuum: From the Neurocritical care unit to home.

Children admitted to neurocritical care units often experience new neurodevelopmental disabilities due to both their acquired neurologic injuries and deconditioning from prolonged hospitalizations. Rehabilitation for critically ill children is multifactorial and begins in the intensive care unit itself. The goals of rehabilitation include prevention of complications associated with immobilization and evolving tone, comprehensive evaluation and treatment of functional deficits, and implementation of adaptive strategies with the goal of maximizing recovery. As a child progresses along the medical continuum from the neurocritical care unit to acute care to post-hospitalization settings, their rehabilitative needs and interventions should also evolve. A child in the neurocritical care unit is likely to have sustained an acquired brain injury. Whether resulting from traumatic or non-traumatic causes, all etiologies of pediatric acquired brain injury can result in significant challenges for the child and their family. Post-intensive care syndrome-pediatrics is a clinical construct that that systematically organizes the range of physical, cognitive, psychological, and social symptoms that emerge in both a child and their family members following a critical illness. Ideally, outpatient care for this population evaluates and supports all areas of post-intensive care syndrome-pediatrics through an interdisciplinary clinical care model. Proactive and comprehensive rehabilitation across the continuum provides the opportunity to support the child and their family in all areas affected, thereby minimizing distress, maximizing function, and optimizing outcomes.

Neurorehabilitation strategies: Assessing the impact on postoperative psychological state, pain, and complications in trigeminal neuralgia.

BACKGROUND: Trigeminal neuralgia is a difficult clinical situation marked by excruciating pain that requires efficient postoperative measures. In patients with trigeminal neuralgia, this study sought to investigate the effects of ongoing rehabilitation intervention on postoperative outcomes, including psychological state, pain, and complications. The aim was to provide new perspectives and treatment strategies for the management of this crippling illness. NEW METHOD: Between January 2021 and December 2022, 120 patients receiving treatment for trigeminal neuralgia were randomized to either the observation or control groups. The observation group received a continuous and comprehensive rehabilitation intervention that included elements of the control group's regimen, while the control group received standard health education and dietary guidance interventions through the use of a digital table method. The assessment of pain scales (VAS), self-rating depression scales (SDS), self-rating anxiety scales (SAS), and complication rates were all part of the postoperative follow-up. RESULTS: At seven days following surgery, there were no appreciable variations in the observation and control groups' VAS, SAS, and SDS scores (P > 0.05). Nevertheless, the observation group showed significantly lower VAS and SAS scores than the control group at 6 months and 1 year following surgery (P < 0.05). The observation group's SDS score was significantly lower than the control group's one year after surgery (P < 0.001). In comparison to the control group, the observation group also showed a lower overall complication rate (P < 0.05), especially in the cases of facial herpes and vertigo. COMPARISON WITH EXISTING METHODS: Our ongoing, all-encompassing rehabilitation approach demonstrated better results than current approaches in terms of long-lasting pain alleviation, enhanced mental health, and lower rates of complications in patients with trigeminal neuralgia following surgery. This implies that, in comparison to traditional methods, incorporating rehabilitation strategies may provide greater therapeutic benefits. CONCLUSION: Continuous comprehensive rehabilitation intervention can effectively reduce the degree of postoperative pain in patients with trigeminal neuralgia, help to regulate their psychological state, and reduce the occurrence of complications, which has certain clinical application value.

Exoskeleton-Assisted Rehabilitation and Neuroplasticity in Spinal Cord Injury.

Spinal cord injury (SCI) results in neurological deficits below the level of injury, causing motor dysfunction and various severe multisystem complications. Rehabilitative training plays a crucial role in the recovery of individuals with SCI, and exoskeleton serves as an emerging and promising tool for rehabilitation, especially in promoting neuroplasticity and alleviating SCI-related complications. This article reviews the classifications and research progresses of medical exoskeletons designed for SCI patients and describes their performances in practical application separately. Meanwhile, we discuss their mechanisms for enhancing neuroplasticity and functional remodeling, as well as their palliative impacts on secondary complications. The potential trends in exoskeleton design are raised according to current progress and requirements on SCI rehabilitation.

Guidelines: basic principles of neurorehabilitation for patients with acquired brain injury. Recommendations of the Spanish Society of Neurorehabilitation.

INTRODUCTION: We present the Spanish Society of Neurorehabilitation's guidelines for adult acquired brain injury (ABI) rehabilitation. These recommendations are based on a review of international clinical practice guidelines published between 2013 and 2020. DEVELOPMENT: We establish recommendations based on the levels of evidence of the studies reviewed and expert consensus on population characteristics and the specific aspects of the intervention or procedure under research. CONCLUSIONS: All patients with ABI should receive neurorehabilitation therapy once they present a minimal level of clinical stability. Neurorehabilitation should offer as much treatment as possible in terms of frequency, duration, and intensity (at least 45-60minutes of each specific form of therapy that is needed). Neurorehabilitation requires a coordinated, multidisciplinary team with the knowledge, experience, and skills needed to work in collaboration both with patients and with their families. Inpatient rehabilitation interventions are recommended for patients with more severe deficits and those in the acute phase, with outpatient treatment to be offered as soon as the patient's clinical situation allows it, as long as intensity criteria can be maintained. The duration of treatment should be based on treatment response and the possibilities for further improvement, according to the best available evidence. At discharge, patients should be offered health promotion, physical activity, support, and follow-up services to ensure that the benefits achieved are maintained, to detect possible complications, and to assess possible changes in functional status that may lead the patient to need other treatment programmes.

Walking naturally after spinal cord injury using a brain-spine interface.

A spinal cord injury interrupts the communication between the brain and the region of the spinal cord that produces walking, leading to paralysis1,2. Here, we restored this communication with a digital bridge between the brain and spinal cord that enabled an individual with chronic tetraplegia to stand and walk naturally in community settings. This brain-spine interface (BSI) consists of fully implanted recording and stimulation systems that establish a direct link between cortical signals3 and the analogue modulation of epidural electrical stimulation targeting the spinal cord regions involved in the production of walking4-6. A highly reliable BSI is calibrated within a few minutes. This reliability has remained stable over one year, including during independent use at home. The participant reports that the BSI enables natural control over the movements of his legs to stand, walk, climb stairs and even traverse complex terrains. Moreover, neurorehabilitation supported by the BSI improved neurological recovery. The participant regained the ability to walk with crutches overground even when the BSI was switched off. This digital bridge establishes a framework to restore natural control of movement after paralysis.

Designing Ecological Auditory Feedback on Lower Limb Kinematics for Hemiparetic Gait Training.

Auditory feedback has earlier been explored as a tool to enhance patient awareness of gait kinematics during rehabilitation. In this study, we devised and tested a novel set of concurrent feedback paradigms on swing phase kinematics in hemiparetic gait training. We adopted a user-centered design approach, where kinematic data recorded from 15 hemiparetic patients was used to design three feedback algorithms (wading sounds, abstract, musical) based on filtered gyroscopic data from four inexpensive wireless inertial units. The algorithms were tested (hands-on) by a focus group of five physiotherapists. They recommended that the abstract and musical algorithms be discarded due to sound quality and informational ambiguity. After modifying the wading algorithm (as per their feedback), we conducted a feasibility test involving nine hemiparetic patients and seven physiotherapists, where variants of the algorithm were applied to a conventional overground training session. Most patients found the feedback meaningful, enjoyable to use, natural-sounding, and tolerable for the typical training duration. Three patients exhibited immediate improvements in gait quality when the feedback was applied. However, minor gait asymmetries were found to be difficult to perceive in the feedback, and there was variability in receptiveness and motor change among the patients. We believe that our findings can advance current research in inertial sensor-based auditory feedback for motor learning enhancement during neurorehabilitation.

Therapeutic intervention with virtual reality in patients with Parkinson's disease for upper limb motor training: A systematic review.

To analyze the scientific evidence regarding changes in upper extremities in patients with Parkinson's disease who use virtual reality as part of their neurological rehabilitation treatment. The search was carried out in the following databases: MEDLINE, Cochrane Library, PEDROs and SCOPUS. The following inclusion criteria were applied to a total of 106 articles: Randomized clinical trials with an age of 5 years, the sample had to be of patients with PD (regardless of their state of involvement) and who had performed RV in the treatment of limbs superiors. A total of n=7 articles were used, in which the variables corresponding to upper limb motor control were measured, such as: fine motor dexterity, gross motor dexterity, strength, tremor, functionality and speed. Virtual Reality as tool in neurorehabilitation in patients with Parkinson's disease shows positive effects in all measurements related to upper limb motor control.

Limb apraxia in individuals with multiple sclerosis: Is there a role of semi-immersive virtual reality in treating the Cinderella of neuropsychology?

BACKGROUND: Limb apraxia is an acquired cognitive-motor disorder characterized by spatial and temporal disorganization of limb movements, negatively affecting the quality of life of patients, including those with multiple sclerosis (MS). Although recent studies have shown the potential role of VR in increasing cognitive and motor functions, only a few studies have been carried out on the rehabilitation of upper limb apraxia. Hence, our study aims to evaluate the potential efficacy of VR training to improve upper limb ideomotor apraxia in patients with MS. METHODS: One hundred and six patients, affected by secondary progressive MS, who attended our Robotic and Behavioral Neurorehabilitation Service from March 2019 to February 2020, were enrolled in this study and randomly divided into two groups: the control group (CG: 53 patients) performed traditional therapy whereas the experimental group (EG:53 patients) received training using semi-immersive VR. All patients underwent the same amount of cognitive training, 3 times a week for 8 weeks. They were submitted to a specific neuropsychological assessment before (T0) and after the rehabilitation treatment (T1). RESULTS: The VR training led to a significant improvement in global cognitive functions, with regard to constructive and ideomotor apraxia. On the contrary, the CG achieved significant improvements only in ideomotor apraxia. Moreover, only in the EG, we observed an improvement in the mood at the end of training. CONCLUSION: The present study demonstrates that VR rehabilitation can be an effective tool for the treatment of apraxia, which is a neuropsychological problem often underestimated in MS patients. Further studies with long-term follow-up periods are needed to confirm the effect of this promising approach.

Effectiveness of physical rehabilitation in improving physical functioning and quality of life for long-term-care residents with dementia: a systematic review protocol.

OBJECTIVE: The objective of this review is to evaluate the effectiveness of physical rehabilitation versus non-rehabilitation control in improving physical functioning and quality of life in long-term care residents with dementia. INTRODUCTION: Many long-term-care residents live with dementia and have impaired physical function and poor quality of life. Physical rehabilitation can improve physical function and quality of life for people living with dementia, yet many long-term-care residents with dementia do not receive this intervention, and health care providers are unsure of which rehabilitation interventions are effective. Studies synthesizing effective rehabilitation programs are needed to guide practice in the long-term-care sector where many residents live with dementia. Previous studies have focused broadly on long-term care, specific professions, interventions or outcomes, or people with dementia in the community. Our review will focus on long-term-care residents living with dementia and a broader definition of physical rehabilitation. INCLUSION CRITERIA: This review will include studies that evaluate physical rehabilitation in comparison with non-rehabilitation controls among long-term-care residents with any severity of dementia. We will include studies that measure the effect on performance-based physical functioning and self- or proxy-reported quality of life. METHODS: Searches will be conducted in APA PsycINFO (EBSCO), CINAHL (EBSCO), MEDLINE (Ovid), Embase, Scopus, and the Cochrane CENTRAL database with no date or language limitations. Two independent reviewers will conduct a critical appraisal of eligible studies, assess methodological quality, and extract the data. Where possible, studies will be pooled in a statistical meta-analysis. SYSTEMATIC REVIEW REGISTRATION NUMBER: PROSPERO CRD42022308444.

Long-Term Clinical Trajectory of Patients with Subarachnoid Hemorrhage: Linking Acute Care and Neurorehabilitation.

BACKGROUND: Despite improvements in the critical care management of subarachnoid hemorrhage (SAH), a substantial number of patients still suffer from disabilities. In most areas of the world, longitudinal follow-up is not routinely performed, and the patient's trajectory remains unknown. METHODS: We prospectively collected data of 298 consecutive patients with spontaneous SAH and evaluated clinical trajectories at discharge, 3 months, and 1 year after SAH. In a subgroup of patients transferred to a local neurorehabilitation center (Rehab-Hochzirl), we studied the effects of rehabilitation intensity on clinical trajectories. Any decrease in the modified Rankin Scale (mRS) was defined as an improvement, with mRS ≤ 2 indicating good outcome. We used multivariate generalized linear models to investigate associations with clinical trajectories. RESULTS: Out of the 250 surviving patients, 35% were transferred directly to Rehab-Hochzirl (n = 87 of 250; mRS at discharge = 4), 11% were transferred to another rehabilitation center (n = 27 of 250; mRS = 1), 1% were transferred to a nursing home (n = 3 of 250; mRS = 5), 21% were transferred to their country of origin (n = 52 of 250; mRS = 4), and 32% (n = 79 of 250; mRS = 1) were discharged home. Functional outcome improved in 57% (n = 122 of 215) of patients during the first 3 months, with an additional 16% (35 of 215) improving between 3 and 12 months, resulting in an overall improvement in 73% (n = 157 of 215) of survivors. After 1 year, 60% (n = 179 of 250) of patients were functionally independent. A lower Hunt and Hess scale score at intensive care unit admission, younger age, a lower mRS at intensive care unit discharge, fewer days on mechanical ventilation, and male sex were independently associated with better functional recovery. Although the subgroup of patients transferred to Rehab-Hochzirl were more severely affected, 60% (52 of 87) improved during inpatient neurorehabilitation. CONCLUSIONS: Our results indicate ongoing functional improvement in a substantial number of patients with SAH throughout a follow-up period of 12 months. This effect was also observed in patients with severe disability receiving inpatient neurorehabilitation.

The Use of Serious Gaming to Improve Sensorimotor Function and Motivation in People with Cerebral Palsy: A Systematic Review.

The aim of this systematic review was to review the evidence for serious gaming interventions in improving sensorimotor function in children and adults with cerebral palsy (CP). Seven databases were searched with terms related to serious gaming and CP. Articles were evaluated according to the Downs and Black rating scale and important principles of serious gaming defined by Whyte et al. Extracted data included the population, intervention, serious gaming elements, outcomes, and authors' conclusions. Fifty-seven articles were identified for inclusion. Participants' ages ranged from 3 to 57 years. Interventions tested included commercial videogames as well as specially designed games. Most interventions had themed content, short-term goals, rewards, feedback, and multiple games. Outcome measures and study designs were inconsistent between studies. Sensorimotor function results of noncomparative studies were positive or neutral overall, but results of comparative studies were more mixed. We concluded that serious gaming interventions may be a useful adjunct to treatment as they are noninvasive, were not associated with deterioration in most cases, and may improve compliance. More comparative studies need to be completed to assess compliance and treatment outcomes. Future games should also aim to adhere more closely to the principles of serious gaming.

Combined Effect of Virtual Reality Training (VRT) and Conventional Therapy on Sitting Balance in Patients with Spinal Cord Injury (SCI): Randomized Control Trial.

Background: Post spinal cord injury (SCI), sitting balance is considered a prerequisite for the effective performance of activities of daily living. Virtual Reality Training (VRT) may provide an interactive medium of rehabilitation, preventing a reduction in active participation of the patients while allowing for the training of sitting balance. Aim: The aim of this study was to evaluate the effect of the addition of VRT to conventional therapy in improving sitting balance in persons with SCI. Subjects and Methods: This was a single blinded randomized control trial conducted on 21 subjects with SCI (level of injury: D10 or below). They were randomly allocated into two groups; both groups received their routine exercise program. In addition, the intervention group, that is, Group B (n = 11) received 30 min of VRT in the seated position using Xbox-Kinect, while the conventional therapy group, that is, Group A (n = 10) received 30 min of additional conventional therapy to equalize the duration of the intervention (3 days/week, 4 weeks). The modified functional reach test and T-shirt test were measured at the beginning and at the end of 4 weeks. Results: MFRT changes for forward (Group A: 1.7 ± 1.09 cm; Group B: 4.83 ± 2.95 cm), right lateral (Group A: 2.43 ± 2.81 cm, Group B: 5.08 ± 1.85 cm), left lateral (Group A: 3.05 ± 4.65 cm, Group B: 6.19 ± 1.51 cm) were statistically significant for Group B (P < 0.05). No significant difference was observed between the two groups for T-shirt test (P > 0.05). Conclusion: VRT can be used as a part of a comprehensive rehabilitation program to improve sitting balance post-SCI.
