Application of the information–motivation–behavioral skills model in rehabilitation training for stroke patients

 

You're that fucking clueless that you UNDERSTAND NOTHING ABOUT SURVIVOR MOTIVATION! My god, I'd have you all fired for stupidity!

My conclusion is you don't understand ONE GODDAMN THING ABOUT SURVIVOR MOTIVATION/DEMORALIZATION, DO YOU? You create EXACT 100% recovery protocols, and your survivor will be motivated to do the millions of reps needed because they are looking forward to 100% recovery. I'd fire all of you for absurd incompetence! GET THERE!

Here's my email: oc1dean@gmail.com Tell me EXACTLY where I'm wrong! Difficulty in getting to those protocols will not be tolerated as an excuse. You've known of this problem of 100% recovery since your education, so you've had years if not decades to work on it! Comeuppance is going to be a bitch when you are the 1 in 4 per WHO that has a stroke? Then you just might want 100% recovery. Or you can be like me where half my life will be disabled!

Abstract

Objective: 

This study aimed to evaluate a multidisciplinary rehabilitation program based on the information–motivation–behavioral skills (IMB) model principles and its association with self-efficacy, functional recovery, quality of life, and caregiver burden among stroke survivors.

Methods: 

A quasi-experimental, non-randomized controlled trial was conducted on 112 stroke patients. The IMB group received a 3-month IMB-based program integrating neurologists, rehabilitation therapists, psychologists, and caregivers, and focusing on information delivery, motivational interviewing, and personalized behavioral training. The usual-care group received standard care. The outcomes included self-efficacy (SSEQ), motor function (Fugl–Meyer Assessment, FMA), daily living ability (Barthel Index, BI), quality of life (SS-QOL), psychological status (Hamilton Depression Rating Scale, HAMD; Hamilton Anxiety Rating Scale, HAMA), and caregiver burden (ZBI), assessed at baseline and post-intervention.

Results: 

The IMB group achieved higher scores than the usual-care group in the following areas: self-efficacy (+82.5% from baseline; SSEQ: 82.5 ± 7.3 vs. 57.8 ± 8.1; p < 0.001), motor function (+79.4%; FMA: 68.9 ± 10.2 vs. 50.3 ± 9.5; p < 0.001), and quality of life (+71%; SS-QOL: 89.4 ± 11.6 vs. 65.2 ± 10.9; p < 0.001). Anxiety (HAMA: 7.5 ± 2.8 vs. 13.6 ± 3.5) and depression (HAMD: 9.2 ± 3.1 vs. 14.8 ± 4.2) scores were lower in the IMB group and fell within the subclinical range (p < 0.001), and caregiver burden was also lower in the IMB group (−31%; ZBI: 28.4 ± 6.3 vs. 41.2 ± 7.1; p < 0.001).

Conclusion: 

The IMB-based multidisciplinary intervention was associated with improved stroke recovery outcomes and reduced caregiver stress. This model suggests a potentially scalable approach that warrants further investigation. Its integration of behavioral strategies with neurorehabilitation principles bridges a critical gap in holistic stroke care, emphasizing the importance of self-efficacy and multidisciplinary collaboration.

1 Introduction

Stroke, a leading cause of mortality and long-term disability worldwide, places a significant burden on healthcare systems and the affected families (1). In China, approximately 3.4 million new stroke cases are reported annually, with more than 70% of survivors experiencing persistent motor dysfunction and reduced quality of life (2, 3). Despite advancements in acute stroke management, post-stroke rehabilitation remains suboptimal, particularly in low-resource settings, in which patient adherence to rehabilitation protocols and caregiver support are critical challenges (4, 5).

Recent studies have emphasized the role of behavioral interventions in addressing these challenges (6, 7). The information–motivation–behavioral skills (IMB) model, initially developed for HIV prevention, has shown promise in chronic disease management by addressing knowledge gaps, enhancing motivation, and fostering actionable behavioral changes (8). Although the IMB model has demonstrated effectiveness in improving outcomes in the management of diabetes and hypertension, its application to stroke rehabilitation is novel. Unlike medication adherence in chronic diseases, stroke recovery requires motor skill relearning, caregiver involvement, and multidisciplinary coordination. Our study uniquely integrates IMB principles with neuroplasticity-based training and caregiver support, addressing these stroke-specific challenges that were not present in prior chronic disease applications (7, 9). Recent studies have recommended its applicability to stroke rehabilitation, where patient self-efficacy and sustained engagement in physiotherapy are pivotal for functional recovery (10). For instance, interventions integrating IMB principles have improved exercise adherence and medication adherence in stroke survivors and reduced their National Institutes of Health Stroke Scale (NIHSS) scores (11). However, existing research predominantly focuses on isolated outcomes (e.g., motor function) and lacks a multidisciplinary approach, limiting its translational impact.

Compounding these issues, stroke recurrence and comorbidities—such as hypertension and diabetes—remain poorly managed in clinical practice (12, 13). A 2025 study demonstrated that dietary modifications, including low-sodium salt substitution, reduced the risk of stroke recurrence by 14% and mortality by 12%, highlighting the need for holistic, patient-centered interventions (14). Concurrently, emerging evidence has highlighted the roles of neuroplasticity and vascular regeneration in post-stroke recovery; however, few studies bridge these biological mechanisms with behavioral interventions (15).

This study aims to address these gaps by evaluating a multidisciplinary IMB-based rehabilitation program for stroke patients. By integrating neurologists, rehabilitation therapists, psychologists, and caregivers, we hypothesize that this approach will be associated with increased self-efficacy, improved motor function, and enhanced quality of life, while alleviating psychological distress(Provide 100% recovery protocols and you remove that distress about not recovering. CAN'T YOU IDIOTS THINK AT ALL?) and caregiver burden. Our study builds on prior findings that early, structured rehabilitation improves cortical reorganization and functional outcomes (16) but innovates by embedding IMB principles into a coordinated care framework tailored to resource-limited settings.

 Detecting major neurological disorders via saliva

A team of Korean researchers has, for the first time in the world, developed a technology capable of enabling early diagnosis of major neurological disorders, including epilepsy, Parkinson's disease, and schizophrenia, using only a small amount of saliva.

This study was conducted jointly by a research team led by Dr. Sung-Gyu Park of the Advanced Bio and Healthcare Materials Research Division at the Korea Institute of Materials Science (KIMS), together with Prof. Ho Sang Jung's team at Korea University and researchers from the College of Medicine at The Catholic University of Korea. The research has recently been published in Advanced Materials, one of the world's leading journals in the field of materials science, drawing significant international attention.

The joint research team developed a Galvanic Molecular Entrapment (GME)–SERS platform that directly detects structural changes in proteins using saliva, replacing conventional diagnostic methods based on blood or cerebrospinal fluid that are costly and invasive. This technology leverages plasmonic "hotspots" that form naturally as proteins are captured on nanostructures composed of copper oxide and gold (Au–CuO).

A key feature of the platform is its ability to amplify the extremely weak Raman signals of biomolecules by more than a billion times. Using this approach, the system can sensitively distinguish protein fibrillation states (monomers versus fibrils), which have been difficult to measure with conventional diagnostic techniques.

The joint research team analyzed saliva samples from a total of 44 patients with epilepsy, schizophrenia, and Parkinson's disease, as well as 23 healthy controls, in collaboration with St. Vincent's Hospital. The results confirmed that the technology can classify these disorders with high accuracy, exceeding 90%, reaching up to 98%.

In particular, the ability to distinguish neurological disorders based on fundamental pathological indicators-namely, structural changes in proteins rather than total protein concentration-is regarded as a rare and significant achievement on a global scale.

An era has begun in which brain disease conditions can be assessed through simple saliva analysis without the need for costly PET imaging or cerebrospinal fluid testing."

As the work has been published in a top-tier international journal, the originality and innovation of the technology have now been formally recognized worldwide. Prof. Ho Sang Jung of Korea University added, "Given its non-invasive and low-cost nature, the technology holds significant potential for expansion beyond hospital outpatient settings to include home-based diagnostic devices."

The research team plans to pursue commercialization by developing portable Raman sensor–based point-of-care diagnostic devices and by promoting technology transfer to medical and life-science companies.

Nature reduces stress by shifting brain activity

From alpha brain waves to amygdala activity, scientists map how forests, wetlands, and even immersive virtual nature can recalibrate the brain, revealing why stepping outside may be one of the most powerful tools for mental resilience.

A recent review in Neuroscience & Biobehavioral Reviews examined how nature exposure affects the brain, identified gaps in current research methods, and suggested areas for future study.

Theoretical Foundations of Nature's Benefits

Several studies have shown that exposure to nature enhances both psychological and physiological well-being. Neuroscience approaches, such as the Exposome, map the combined effects of environmental exposures and biological factors on brain health, but can be enriched by examining specific cognitive and emotional processes involved in well-being.

Spending time in nature improves attention, reduces stress, and increases positive mood. Researchers have proposed three main ecopsychology theories to explain these effects. The Attention Restoration Theory (ART) suggests that nature helps restore attentional focus, while the Stress Recovery Theory (SRT) proposes that natural environments rapidly reduce stress and promote recovery. The third Biophilia Hypothesis argues that humans have an innate drive to connect with nature, which may underlie these restorative effects.

Assessing Neural Mechanisms of Nature Exposure

Theoretical frameworks do not account for the neural mechanisms through which nature influences cognition and emotion. Even though systematic reviews and meta-analyses confirm that contact with green spaces is linked to better physical and mental health, most research fails to examine the neural mechanisms underlying this association.

The present study assesses neuroimaging studies examining how natural stimuli influence brain function and cognitive-affective processing across real-world environments and controlled laboratory settings. It evaluated 108 peer-reviewed studies examining the neurobiological impact of nature exposure with techniques such as electroencephalogram (EEG), Magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and functional near-infrared spectroscopy (fNIRS).

The current study examined factors such as stimulus complexity, environmental type, and study design to clarify the neural mechanisms linking nature exposure to cognition and emotion, highlight existing gaps, and suggest future research directions.

The majority of EEG studies focused on pictorial, video, and virtual environment (VE) paradigms, while fMRI and fNIRS studies included both lab and field exposures. MRI studies leveraged database analyses and post-exposure assessments. This diversity highlights a robust body of neuroimaging evidence on nature exposure, although protocols varied substantially in stimulus type, duration, and outcome measures, limiting direct comparability across studies.

The current review featured diverse participants, with most EEG, fMRI, and fNIRS samples consisting of young to middle-aged adults (ages 18–55) and a balanced gender distribution.

Determinants and Durability of Nature’s Neurobiological Effects

Nature exposure yielded quantifiable benefits across neural, emotional, and physiological domains. EEG and event-related potential (ERP) research consistently demonstrates that nature exposure increases alpha power, indicative of enhanced relaxation and inward-focused attention, and promotes greater neural connectivity. In contrast, urban settings were associated with elevated beta and gamma activity, markers of increased arousal and stress.

Green environments enhanced both emotional and cognitive indicators of well-being, with prolonged or immersive exposures amplifying these effects relative to brief or simulated experiences. Field and laboratory investigations further established that blue spaces, such as wetlands, conferred the most rapid and pronounced stress recovery, followed by open and closed green spaces. In contrast, grey spaces, typically urban or built environments, were repeatedly shown to be the least effective in facilitating recovery.

The magnitude of these benefits depended on several factors. An exposure duration of at least 15 minutes and high environmental quality, characterized by visual richness, cleanliness, and perceived safety, further amplified positive outcomes. Engagement in horticultural activities or relaxation in authentic green or blue spaces resulted in significant improvements in neural relaxation (e.g., increased alpha power), mood, and stress reduction.

Although immersive virtual environments also demonstrated measurable benefits, real-world exposure often produced stronger or more consistent restorative effects, while simulated environments or indoor rest typically failed to elicit comparable restorative responses.

Key environmental features, including greenness, openness, presence of natural water bodies, and minimal visual clutter, were shown to optimize the restorative potential of outdoor spaces. Furthermore, sitting and walking generally produced stronger restorative EEG signatures than talking or cognitively demanding activities during exposure.

Visual exposure to nature, relative to auditory stimuli alone, produced stronger and more rapid well-being gains, with measurable benefits apparent after approximately 8–9 minutes of exposure.

To integrate findings across imaging modalities, the authors propose a multilevel neurobiological cascade linking perceptual, autonomic, cognitive, and affective systems. In this model, natural scenes are processed efficiently by early visual regions, reducing perceptual load; limbic and autonomic circuits then downregulate stress responses; alpha–theta synchronization supports attentional restoration; and increased connectivity within default mode network regions may promote emotional coherence and a sense of connectedness.

Critically, repeated engagement with restorative environments over extended periods may induce enduring changes in brain structure and function, though much of the structural MRI evidence remains correlational and based on long-term associations with residential greenspace, thereby supporting neurobiological resilience and providing a mechanistic link between acute restorative effects and long-term improvements in mental and physical health.

Conclusion

Neuroimaging research provides compelling evidence that exposure to natural environments confers diverse neural, cognitive, and emotional benefits. However, most of the reviewed studies were conducted in healthy adult populations and relied on heterogeneous, often correlational designs, meaning the findings should not be interpreted as definitive causal proof or generalized to clinical groups. The authors also note the possibility of publication bias and call for more preregistered, longitudinal, and mechanistic trials.

Future studies should leverage longitudinal designs, incorporate ecological momentary assessment, and explore underlying neurobiological mechanisms in more diverse and clinical cohorts. Expanding interdisciplinary approaches can inform the integration of nature-based interventions into urban design, public health policy, and personalized mental health care, maximizing restorative outcomes for society at large.

Researchers reveal why SuperAgers retain youthful brain cell signatures into their 80s

A multiomic atlas of the aging human hippocampus uncovers how epigenetic regulation of neural stem cells and immature neurons may shape cognitive decline or resilience in later life.

In a recent study published in the journal Nature, researchers delineated neurogenesis in the human hippocampus across adulthood, aging, and Alzheimer’s disease (AD), while noting that the functional relevance of these processes for human cognition remains incompletely understood.

Humans

The epigenetic and transcriptional mechanisms underlying the generation of neurons from neural stem cells (NSCs) are well established in rodents. Hippocampal neurogenesis plays a vital role in memory and learning by recruiting immature neurons into memory circuits and promoting memory formation. Neurogenesis decreases with age and is impaired in mouse AD models.

In contrast, the fate of neurogenesis in humans is poorly defined. The occurrence of neurogenesis in the adult hippocampus has been debated. The presence of immature neurons has been confirmed in the adult human brain and in AD. A subset of progenitor cells shows signs of ongoing proliferation in the adult human brain; nonetheless, key knowledge gaps remain, particularly regarding how these molecular signatures translate to functional cognitive outcomes.

Single-Nucleus Multi-Omic Profiling of the Human Hippocampus

Researchers analyzed nuclei isolated from human post-mortem hippocampi using a single-nuclei assay for transposase-accessible chromatin with sequencing (snATAC-seq) and single-nucleus RNA sequencing (snRNA-seq). Sequence profiles from 85,977 nuclei of young adults with intact memory, referred to as the young adult cohort, were analyzed to establish neurogenic regulatory pathways.

Unsupervised clustering of snRNA-seq data identified 12 cell types in the hippocampus, including neuroblasts, astrocytes, immature neurons, mature granule cells, oligodendrocyte progenitor cells, and mature oligodendrocytes. Differential gene expression and pathway analyses identified 169 pathways and 4,166 differentially expressed genes (DEGs), all of which were upregulated in neuroblasts compared to mature oligodendrocytes.

Developmental Trajectories and RNA Velocity Analyses

Latent times of neuroblast, astrocyte, mature granule cell, and immature neuron clusters were examined to identify NSCs and their developmental trajectories using RNA velocity analysis. This showed a directional flow from NSCs to astrocytes and toward neuroblasts to mature granule cells via immature neurons. NSCs expressed low levels of neuronal markers but high levels of stemness proxies compared with immature neurons and neuroblasts.

The snATAC-seq analysis allowed an orthogonal evaluation of stemness via chromatin accessibility. High chromatin accessibility was observed in regions associated with multi-lineage potential in NSCs. In contrast, neuronal maturation proxies showed high levels of open chromatin in immature neurons and neuroblasts. The top differentially accessible regions (DARs) and DEGs in NSCs were downregulated in immature neurons and neuroblasts.

Conversely, the top DARs and DEGs in neuroblasts were downregulated in NSCs. The top DEGs in immature neurons had low expression in NSCs and moderate expression in neuroblasts. Developmental pathways were downregulated in immature neurons and neuroblasts but enriched in NSCs. The top motifs in NSCs included signal transducer and activator of transcription 3 (STAT3), STAT4, STAT5, nuclear factor I B (NFIB), and pleomorphic adenoma gene-like 1 (PLAGL1).

In immature neurons, the top motifs included nuclear factor erythroid 2 (NFE2), PBX homeobox 2 (PBX2), Meis homeobox 2 (MEIS2), and regulatory factor X2 (RFX2). These patterns suggest a shift from transcription factors that promote stem cell proliferation and maintenance in NSCs to those that regulate differentiation and maturation in immature neurons. Researchers then examined the effects of cognitive diagnosis and age on neurogenesis.

Neurogenesis Across Aging, Preclinical Pathology, and Alzheimer’s Disease

Hippocampal nuclei were sequenced from healthy agers without cognitive impairment, adults with AD, and adults with preclinical intermediate pathology. Samples from SuperAgers were also analyzed. These individuals were aged 80 years or older and performed on episodic memory tests at levels comparable to or better than those of individuals aged 50 to 59 years. All cell types detected in the young adult cohort were observed in these groups.

AD and preclinical pathology groups had significantly more NSCs than healthy agers. The AD cohort had significantly fewer immature neurons and neuroblasts than both young adults and healthy agers, and fewer immature neurons than the preclinical pathology group. Most diagnosis- and age-related changes were observed in DAR counts rather than DEG counts, highlighting chromatin accessibility as a stronger discriminator of cognitive trajectories than transcript abundance alone.

A subset of DARs was specifically downregulated in immature neurons and neuroblasts in the preclinical pathology group compared with SuperAgers, healthy agers, and young adults. These DARs were further downregulated in AD. These findings suggest that alterations in chromatin accessibility may contribute to disrupted neurogenic trajectories during cognitive decline. Some of the earliest age-related shifts were detectable in chromatin accessibility at the NSC stage.

Cognitive Resilience Signatures in SuperAgers

The SuperAger cohort exhibited a significantly higher number of immature neurons compared with other groups and more neuroblasts than the AD cohort. This profile was attributable to DAR patterns. The SuperAger cohort had 7,058 and 674 DARs upregulated in immature neurons and neuroblasts, respectively, compared with other cohorts.

Resilience scores were calculated to detect consistent directionality of chromatin and transcriptional effects across cohorts rather than to directly measure cognitive performance. A clear signature was observed in immature neurons and neuroblasts, with most peaks and genes remaining stable in SuperAgers, young adults, and healthy agers, but downregulated in AD.

Additional analyses indicated that preserved excitatory synapse integrity was a hallmark of healthy cognitive aging. Regulatory interactions involving astrocytes and CA1 pyramidal neurons also distinguished successful from pathological aging. The authors note that relatively small cohort sizes and substantial inter-individual variability warrant cautious interpretation.

Conclusions and Therapeutic Implications

The study outlined molecular signatures of neurogenesis in the human hippocampus and their changes across age and cognitive status. Differences in chromatin accessibility across the neurogenic spectrum suggest that epigenetic alterations may be more definitive signatures of aging-associated cognitive trajectories than gene expression changes alone. Delineating these mechanisms and their interaction with broader hippocampal network dynamics may inform targeted therapeutic strategies to preserve cognitive function in aging. However, further research is required to establish causal links between these molecular patterns and cognitive performance.
