Key Takeaway
Very early exercise rehabilitation may improve NIHSS and functional scores in stable ICH patients, despite low evidence certainty.

This meta-analysis evaluates the clinical impact of timing in exercise rehabilitation for patients diagnosed with intracerebral hemorrhage (ICH). By comparing very early intervention against standard early rehabilitation, the study aims to determine if immediate mobilization improves neurological and functional recovery in the acute phase. The analysis included a total of 1,396 patients, providing a substantial sample size to assess primary outcomes including the National Institutes of Health Stroke Scale (NIHSS), Fugl-Meyer Assessment, and Barthel Index variants.

In terms of primary outcomes, the data indicates that very early rehabilitation is associated with superior results across multiple scales. Specifically, patients receiving very early intervention demonstrated a statistically significant improvement in NIHSS scores compared to those in the early rehabilitation group. This suggests that immediate physical engagement may mitigate some neurological deficits shortly after the hemorrhagic event. The Fugl-Meyer Assessment also showed a notable improvement, indicating better motor function and coordination in the early intervention cohort.

Functional independence measures also favored the very early intervention group. The Modified Barthel Index and the standard Barthel Index both showed statistically significant improvements. While the magnitude of the mean difference in the Modified Barthel Index was modest, the consistency across these metrics suggests that early mobilization contributes to better activities of daily living (ADL) scores. These findings provide a basis for reconsidering the initiation window for physical therapy in stable ICH patients.

Safety profiles were monitored through secondary outcomes including rebleeding, hemodynamic instability, and falls. While these are critical risks in the acute management of intracerebral hemorrhage, the current data does not provide a definitive comparative safety profile between the two intervention timings. Clinicians must weigh the potential for improved functional outcomes against the inherent risks of early mobilization in the acute setting.

However, the clinical application of these findings must be tempered by several limitations identified in the study. Significant heterogeneity was observed across the included studies, which can obscure the consistency of the effect. Furthermore, the reporting of safety data was incomplete, and the overall certainty of evidence for all primary outcomes is currently rated as low. These factors necessitate a cautious interpretation of the results when designing clinical pathways.

In practice, these findings suggest that for clinically stable patients with intracerebral hemorrhage, initiating exercise rehabilitation as early as possible may be associated with better neurological and functional outcomes. However, because of the low certainty of evidence and high heterogeneity, clinicians should integrate these findings with individual patient stability and risk profiles. A multidisciplinary approach remains essential to ensure that the timing of rehabilitation optimizes recovery while maintaining patient safety.

How this fits prior evidence

How this fits prior evidence This meta-analysis addresses a gap in the management of functional recovery following intracerebral hemorrhage. While previous evidence noted that ICH survivors face an annual 2.1% risk of recurrent ICH and a 2.0% risk of ischemic stroke, this study focuses on the timing of rehabilitation to improve outcomes. It does not directly relate to the findings regarding tranexamic acid, remote DWI lesions, hematoma expansion markers, or shunt pressure titration.

When someone suffers from an intracerebral hemorrhage, which is a type of bleeding inside the brain, the road to recovery can be long and difficult. For these patients, regaining the ability to move, speak, and perform daily tasks is the ultimate goal. Because the brain controls everything from walking to basic self-care, the timing of physical therapy is a major concern for families and doctors. They want to know when the best time is to start moving the body to help the brain heal.

To find answers, researchers looked at data from 1,396 patients who experienced this type of brain bleed. They compared two different approaches: starting exercise rehabilitation very early in the recovery process versus starting it a bit later during the early phase. The goal was to see if starting movement sooner would lead to better physical outcomes for those who were medically stable.

The results showed that patients who began their exercise rehabilitation very early had better scores across several different tests. These tests measured things like overall neurological status, the ability to perform basic daily activities, and physical movement. Specifically, the early exercise group showed improvements in the National Institutes of Health Stroke Scale and the Fugl-Meyer Assessment. They also performed better on the Barthel Index, which tracks how well a person can manage daily life. These scores suggest that moving sooner may help patients regain their independence more effectively.

However, it is important to look at the full picture. While the results are encouraging, the researchers noted some significant hurdles in the data. There was a lot of variety in how the different studies were conducted, which is called heterogeneity. Additionally, the reports on safety were not complete, and the overall certainty of the evidence is considered low. This means that while the trend looks positive, the data is not perfectly clear yet.

For patients and families right now, this means that while early exercise shows promise, it is not a guaranteed fix. Because the evidence is still not fully certain, doctors will continue to make decisions based on each patient's specific stability and needs. It highlights that early movement is a promising path for recovery, but it must be balanced with careful medical oversight to ensure the patient remains safe during the process.

What this means for you:
Very early exercise may improve physical recovery for brain bleed patients, but evidence is currently limited.

BACKGROUND: The optimal timing of rehabilitation initiation after intracerebral hemorrhage (ICH) remains uncertain. This systematic review and meta-analysis compared the efficacy and safety of very early versus early exercise rehabilitation after ICH. METHODS: Chinese Biomedical Literature Database, China National Knowledge Infrastructure, Chinese Science and Technology Journal Database/VIP Database, Wanfang, PubMed, Embase, the Cochrane Library, Web of Science, ClinicalTrials.gov, and the Chinese Clinical Trial Registry were searched from inception to October 10, 2023. Randomized controlled trials comparing very early with early exercise rehabilitation after ICH were included. Two reviewers independently screened studies, extracted data, and assessed risk of bias. Continuous outcomes were pooled as mean differences (MDs) with 95% confidence intervals (CIs). Certainty of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation approach. Primary outcomes included the National Institutes of Health Stroke Scale, Fugl-Meyer Assessment, Modified Barthel Index, and Barthel Index. RESULTS: Seventeen randomized controlled trials involving 1396 participants were included. Compared with early rehabilitation, very early rehabilitation was associated with better outcomes for National Institutes of Health Stroke Scale (MD = -3.89, 95% CI: -5.00 to -2.78), Fugl-Meyer Assessment (MD = 10.24, 95% CI: 6.80-13.68), Modified Barthel Index (MD = 0.92, 95% CI: 0.73-1.11), and Barthel Index (MD = 1.89, 95% CI: 1.70-2.08). Substantial heterogeneity was observed across the pooled analyses. Standardized safety outcomes, including rebleeding, hemodynamic instability, and falls, were insufficiently reported for quantitative synthesis. The certainty of evidence was low for all outcomes. CONCLUSION: In clinically stable patients with ICH, very early exercise rehabilitation may be associated with better neurological and functional recovery than rehabilitation initiated later within the early phase. However, the findings should be interpreted cautiously because of substantial heterogeneity, incomplete safety reporting, and low certainty of evidence.
