Stroke is a leading cause of death and disability, with survivors often facing upper extremity (UE) impairments. Mirror therapy (MT) can enhance motor function but is influenced by cognitive and emotional factors. Robot-assisted therapy (RT) has shown efficacy in restoring UE function. Robot-mirror therapy (RMT), which combines MT and RT, has been investigated in several trials, with some showing benefits while others reported limited effects. This meta-analysis aimed to evaluate RMT’s effectiveness in improving UE function in stroke patients.
We included RCTs involving RMT in adult stroke patients. Searches covered ten databases (Cochrane Library, Scopus, PubMed, Web of Science, Embase, CNKI, CINAHL, PEDro, ClinicalTrials.gov, WHO ICTRP) through October 2025, with a grey literature search. Two independent reviewers conducted study selection, data extraction, and quality assessment. The risk of bias and the certainty of the evidence were assessed using the Cochrane collaboration’s tool and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) guideline, respectively.
Sixteen RCTs (n=736) were analyzed. RMT significantly improved UE motor function (Fugl-Meyer Assessment-Upper Extremity (FMA-UE); MD 7.52, 95% CI 4.16-10.87; P<.0001 and Wolf Motor Function Test; MD 5.13, 95% CI 2.33-7.92; P=.0003), distal UE motor function (FMA-UE (distal); MD 2.92, 95% CI 1.43-4.42; P=.0001), hand motor function (SMD 1.06, 95% CI 0.15-1.97; P=.02), hand muscle strength (grip strength; SMD 1.34, 95% CI 0.17-2.51; P=.02), activities of daily living (Modified Barthel Index; MD 7.80, 95% CI 4.15-11.45; P<.0001 and Functional Independence Measure; MD 4.73, 95% CI 0.30-9.15; P=.04), and quality of life (SMD 1.00, 95% CI 0.00-1.99; P=.05). Subgroup analysis showed better outcomes in older patients (≥55), shorter interventions (<18 hours), and trial length of 3–6 weeks.
Moderate-quality evidence supports the effectiveness of RMT-based interventions for improving UE motor function and activities of daily living in stroke patients.

Hugh Chatham Health has been recognized as one of America’s Best Hospitals for Stroke Care by the Women’s Choice Award, placing it among the top-performing hospitals nationwide. This designation signifies that Hugh Chatham Health ranks in the top 9% of over 4,600 U.S. hospitals offering stroke care services.
I'd fire everybody involved in this travesty of 'care' rather than recovery! BEST, my ass!
According to the American Stroke Association:
• 1 in 5 women will experience a stroke in her lifetime
• Women account for nearly 60% of stroke-related deaths
• Studies show women are more likely to be misdiagnosed for stroke—even when presenting with the same symptoms as men
“Timely diagnosis and effective care are critical to preventing disability and improving recovery outcomes,” said Delia Passi, founder and CEO of the Women’s Choice Award. “The time to identify your community’s leading hospital for stroke care is now — not in the middle of a medical emergency when every minute counts.”
The Women’s Choice Award for Stroke Care is the only national designation that combines clinical excellence, patient satisfaction, and women’s healthcare preferences to identify top-performing hospitals.
To qualify, hospitals must:
• Hold a Stroke Center Certification from the Joint Commission (JC) and/or Det Norske Veritas (DNV) [points assigned for different levels of certification]
• Meet or exceed performance measures from CMS, including:
• Top 80% of hospitals for timely Head CT scan results (within 45 minutes)
• No rating of “Worse than the National Rate” for deaths from serious treatable complications
The methodology also includes:
• HCAHPS survey results (patients who “definitely recommend” the hospital)
“Receiving top care within the first three hours of a stroke is critical to preventing long-term disability,” added Passi. “Our award helps women—and their families—identify hospitals where they have the best chance of a full recovery.”
Hugh Chatham Health is one of 503 hospitals nationwide to earn this prestigious recognition for 2026.
Mary Blackburn, Chief Operating Officer and Senior Vice President at Hugh Chatham Health, said “At Hugh Chatham Health, we are deeply committed to providing every patient with the highest-quality, safest care possible. Receiving another Women’s Choice Award for Stroke Care is a meaningful affirmation of the expertise, teamwork, and dedication of our providers, clinical staff, and teammates. We are proud to be recognized for the important work we do each day to improve the lives of people in the Yadkin Valley who are affected by stroke, giving them the best possible chance for recovery and survival.”
Summary: Researchers have identified two specific proteins, gliomedin and CNTNAP4, that act as a “handshake” mechanism allowing inhibitory chandelier cells to connect precisely with excitatory pyramidal neurons. This connection is vital for maintaining electrical balance in the brain. Disruptions in this process are linked to neurological disorders such as epilepsy, schizophrenia, and autism.

The brain’s ability to process information relies on a delicate balance between neurons that send “go” signals and those that send “stop” signals. Now, researchers have discovered exactly how the “conductors” of this orchestra find their way to the podium.
A new study from Ohio State University reveals how chandelier cells—a class of inhibitory interneurons—link up with their target excitatory cells. The team identified two specific molecules that must be present to enable a “handshake” between the cells, allowing synapses to form.
Chandelier cells are critical for brain function. They connect to a specific location on target excitatory neurons (pyramidal cells) called the axon initial segment. By grabbing this “handle,” chandelier cells can powerfully suppress the activity of the excitatory neurons, effectively preventing runaway electrical signals.
“These inhibitory interneurons shape and balance local circuit activity – they are the modulators, coordinators, the conductors of the orchestra,” said Yasufumi Hayano, lead author and postdoctoral scholar at Ohio State University. “From our results, we’ve concluded that interaction between two specific proteins regulates the specificity of their synapse formation.”
Loss of coordination between these cell types is associated with severe neurological and psychiatric disorders, including epilepsy, depression, autism, and schizophrenia.
The researchers discovered that the connection relies on a precise molecular interaction. The study identified two key proteins:
When these two proteins meet, they facilitate the formation of the synapse. Using visualizations in the brains of young mice, the team observed that when the genes for gliomedin were removed, the chandelier cells failed to form adequate connections with their targets. The “handshake” was broken, leaving the “conductors” unable to control the orchestra.
Because the axon initial segment is the exact site where neurons generate action potentials (the signals used to communicate), chandelier cells have a disproportionately strong influence on brain activity. They essentially control the “faucet” of information flow.
“This is basic neuroscience, but there might be an impact for neuronal disorders,” said Hayano. “If this process is disrupted, what happens? If we lose those genes, which neuronal disorder might occur? We still don’t know, but those possibilities should be explored.”
Senior author Hiroki Taniguchi noted that understanding these developmental mechanisms is the first step toward identifying therapeutic targets for conditions where brain circuitry is imbalanced.

Older adults who adhered to a structured lifestyle intervention saw greater improvement from blood flow and regulation mechanisms in both the brain and heart at 2 years than those who used a self-guided intervention, , data show.
“Multiple lines of evidence highlight the importance of vascular contributions to cognitive impairment and dementia,” Tina Brinkley, PhD, associate professor of gerontology and geriatrics, internal medicine at Wake Forest University School of Medicine, told Healio about the updated research from the POINTER study presented at CTAD.
“While most of this research is focused on vascular pathology found in the brain (which is) detectable on an MRI or PET scan, systemic or peripheral measures that reflect the health of blood vessels throughout the body and how well these vessels communicate with the brain is also very important,” she said.
As cardiovascular health plays an integral role in overall health in older adults, Brinkley and colleagues sought to investigate the neurovascular mechanisms that underlie intended effects of lifestyle interventions.
The POINTER-NV neurovascular ancillary study examined 491 individuals from the parent POINTER study without atrial fibrillation or a pacemaker at baseline (mean age, 68.1 years; 61% women) and randomly assigned them on a 1:1 basis to either the structured lifestyle intervention including a rigorous schedule of diet and exercise (n = 246; mean age, 68.1 years; 58% women) or a self-guided intervention (n = 245; mean age, 68.2 years; 65% women).
Neurovascular assessments, which included heart rate variability, aortic function and carotid arterial flow, were performed at baseline, 12 months and 24 months.
The primary outcome for POINTER-NV was average change from baseline of baroreflex sensitivity (expressed as milliseconds per millimeters of Mercury[ms/mmHg]), with secondary outcomes including measurements of blood flow in the heart and brain, autonomic function as well as structural and functional measurements in the heart and brain.
Covariates for analysis were baseline age, sex and race.
According to results, those assigned to the structured lifestyle intervention recorded a mean change in baroreflex sensitivity of 1.177 ms/mmHg (95% CI: 0.634-1.72) from baseline to 2 years, while those in the self-guided intervention group recorded a mean change in that same interval of 0.291 ms/mmHg (95% CI: -0.246-0.828).
The mean adjusted difference between the structured vs. self-guided interventions was also significantly higher for men (1.921 vs. 0.337) and those aged 70 years or older (1.893 vs. 0.213) compared with that for women (0.606 vs. 0.265) and those aged younger than 70 years (0.699 vs. 0.349)
The researchers additionally reported the mean comparative changes from baseline to 2 years in structured vs. self-guided interventions:
All indicated positive effects for the structured intervention, Brinkley and colleagues wrote.
The comprehensive neurovascular assessment performed in POINTER-NV will be crucial for future clinical assessments and protocols through its identification of which measures of neurovascular health are most relevant to the patient population, she said.
“Collectively, these changes could protect the brain from excessive blood pressure and pulsatile blood flow, which negatively impact brain structure and function,” Brinkley told Healio. “In the long run, these benefits may help to preserve cognitive function and lower the risk for dementia in U.S. POINTER participants.”
