Abstract
Spontaneous recovery frequently proves maladaptive or insufficient because the plasticity of the injured adult mammalian central nervous system is limited. This limited plasticity serves as a primary barrier to functional recovery after brain injury. Neuromodulation technologies represent one of the fastest-growing fields in medicine. These techniques utilize electricity, magnetism, sound, and light to restore or optimize brain functions by promoting reorganization or long-term changes that support functional recovery in patients with brain injury. Therefore, this review aims to provide a comprehensive overview of the effects and underlying mechanisms of neuromodulation technologies in supporting motor function recovery after brain injury. Many of these technologies are widely used in clinical practice and show significant improvements in motor function across various types of brain injury. However, studies report negative findings, potentially due to variations in stimulation protocols, differences in observation periods, and the severity of functional impairments among participants across different clinical trials. Additionally, we observed that different neuromodulation techniques share remarkably similar mechanisms, including promoting neuroplasticity, enhancing neurotrophic factor release, improving cerebral blood flow, suppressing neuroinflammation, and providing neuroprotection. Finally, considering the advantages and disadvantages of various neuromodulation techniques, we propose that future development should focus on closed-loop neural circuit stimulation, personalized treatment, interdisciplinary collaboration, and precision stimulation.

[PMID: 40287478 PMCID: PMC12033361 DOI: 10.1038/s41598-025-99418-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2024] [Accepted: 04/21/2025] [Indexed: 04/29/2025] Open
Abstract
Hypoxia-inducible factor 1 A (HIF1A) is considered as a potential marker gene for ischemic stroke (IS), its gene polymorphism may affect IS risk and may be related to the IS pathological process. In this study, a total of 159 IS patients and 141 healthy controls were enrolled by case-control study method. HIF1A three single nucleotide polymorphisms (SNPs: rs10873142, rs11549465, rs11549467) were genotyped by SNaPshot method and HIF1A protein levels was detected by enzyme-linked immunosorbent assay (ELISA), then the correlation between HIF-1 A SNPs and IS was analyzed by statistical analysis method. The genotype of HIF1A SNPs can affect the expression levels of clinical and laboratory parameters in IS patients, such as high-density lipoproteincholesterol (HDL-C), apolipoprotein A1, reactive oxygen species (ROS). HIF1A TCG haplotype is a protective factor for IS, HIF1A CCG haplotype is a risk factor for IS. However, the association between HIF1A rs10873142, rs11549465, rs11549467 genotypes and the IS risk was not statistically significant. ELISA analysis showed that the HIF1A expression of IS patients is higher than the healthy controls. Therefore, the gene polymorphism and expression of HIF1A may be related to IS pathological process, but the relationship between HIF1A gene polymorphism and the IS risk still needs further study.

Hwang S, Song CS. Rehabilitative effects of electrical stimulation on gait performance in stroke patients: A systematic review with meta-analysis. NeuroRehabilitation 2024; 54:185-197.

Abstract
BACKGROUND Electrical stimulation techniques are widely utilized for rehabilitation management in individuals with stroke patients. OBJECTIVES This review aims to summarize the rehabilitative effects of electrical stimulation therapy on gait performance in stroke patients. METHODS This review included randomized controlled trials (RCT) investigating the therapeutic effects of electrical stimulation in stroke patients throughout five databases. This review qualitatively synthesized 20 studies and quantitatively analyzed 11 RCTs. RESULTS Functional electrical stimulation (FES) was the most commonly used electrical stimulation type to improve postural stability and gait performance in stroke patients. The clinical measurement tools commonly used in the three studies to assess the therapeutic effects of FES were Berg balance scale (BBS), 10-meter walk test (10MWT), 6-minute walk test (6mWT), and gait velocity. The BBS score and gait velocity had positive effects in the FES group compared with the control group, but the 10MWT and 6mWT showed the same effects between the two groups. The heterogeneity of BBS scores was also high. CONCLUSION The results of this review suggest that electrical stimulation shows little evidence of postural stability and gait performance in stroke patients, although some electrical stimulations showed positive effects on postural stability and gait performance.

Test-Retest Reliability and Agreement of Single Pulse Transcranial Magnetic Stimulation (TMS) for Measuring Activity in Motor Cortex in Patients With Acute Ischemic Stroke. Neurosci Insights 2022; 17:26331055221145002. [PMID: 36578525 PMCID: PMC9791285 DOI: 10.1177/26331055221145002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2022] [Accepted: 11/28/2022] [Indexed: 12/25/2022] Open
Abstract
Background Transcranial magnetic stimulation (TMS) is often used to examine neurophysiology. We aimed to investigate the inter-rater reliability and agreement of single pulse TMS in hospitalised acute ischemic stroke patients. Methods Thirty-one patients with first-time acute ischemic stroke (median age 72 (IQR 64-75), 35% females) underwent TMS motor threshold (MT) assessment in 4 muscles bilaterally, conducted by 1 of 2 physiotherapists. Test-retest reliability was evaluated using a two-way random effects model (2,1) absolute agreement-type Interclass Correlation Coefficient (ICC). Standard Error of Measurement (SEM) and Smallest Detectable Change (SDC) were used to evaluate agreement. Results Reliability, SEM, and SDC of TMS was found to be moderate in right opponens pollicis (0.78 [CI 95% 0.55-0.89], SEM: 4.51, SDC: 12.51), good in right vastus medialis and tibial anterior (0.88 [CI 95% 0.72-0.96], SEM: 2.89, SDC: 8.01 and 0.88 [CI 95% 0.76-0.94], SEM: 2.88, SDC: 7.98 respectively), and excellent in right and left biceps brachii (0.98 [CI 95% 0.96-0.99], SEM: 1.79 SDC: 4.96, and 0.94 [CI 95% 0.89-0.97], SEM: 2.17 SDC: 6.01), opponens pollicis (0.92 [CI 95% 0.83-0.96], SEM: 2.68 SDC: 8.26, vastus medialis (0.92 [CI 95% 0.84-0.96], SEM: 2.87 SDC: 7.95), and tibial anterior (0.93 [CI 95% 0.86-0.96], SEM: 2.51 SDC: 6.95). Conclusion The TMS demonstrated moderate to excellent inter-rater reliability confirming the ability of these measures to reliably discriminate between individuals in the current study sample. Improvements of less than 4.96 to 12.51 could be a result of measurement error and may therefore not be considered a true change.
