According to a new analysis of global rehabilitation research, telerehabilitation—delivered via video calls or apps—may offer similar benefits to in-person care for stroke recovery, but current evidence is too limited to recommend it as a universal replacement. The findings, published as part of a broader study on rehabilitation policy, highlight gaps in how health systems organize care, with most research focused on high-income countries and leaving critical questions unanswered for lower-income regions.
The review, which examined 25 systematic reviews but could use data from only five, found no strong evidence that using specialist physiotherapists instead of doctors improves outcomes. Similarly, there is no reliable proof that receiving rehabilitation at home, in hospitals, or in clinics yields better results than other settings. However, for stroke survivors, telerehabilitation showed comparable effectiveness to in-person care in areas like mobility, arm function, and mental well-being—though researchers stressed the need for more rigorous studies.
“Nearly all studies were conducted in high-income countries, leaving major gaps in understanding how these delivery models work in diverse settings,” said the report, which noted that no evidence exists from Africa, Southeast Asia, or the Eastern Mediterranean. The analysis, current as of November 17, 2024, also flagged low confidence in most findings, meaning future research could alter current conclusions.
Who provides rehabilitation—and does it matter?
The review found that shifting care from doctors to other trained professionals, such as physiotherapists, does not significantly change health outcomes for patients. “There’s no meaningful difference in effectiveness when comparing care from doctors versus other specialists,” the report stated, based on five usable systematic reviews. This challenges assumptions that certain providers inherently deliver better results, though the data did not explore whether patient satisfaction or access varied by provider type.
For stroke survivors—a population heavily studied in the reviews—telerehabilitation emerged as a potential alternative to in-person therapy. Studies suggested that video-based or phone-delivered rehabilitation produced similar improvements in daily independence, depression scores, and physical function. However, the evidence base was small: only a handful of trials met rigorous standards, and most were conducted in Europe, North America, or Australia.
Where care happens: hospitals, homes, or clinics?
The analysis found no conclusive evidence that the location of rehabilitation—whether in hospitals, outpatient clinics, or patients’ homes—affects outcomes. A few studies compared home-based care to traditional settings, reporting comparable results, but the authors warned that the data was too weak to draw firm conclusions. “The number of studies was limited, and confidence in these findings is low,” the review noted.
This uncertainty extends to telerehabilitation, which, while promising, lacks sufficient long-term data. “We can’t yet say whether digital rehabilitation is as good as in-person care for everyone,” the report concluded. For now, health systems may need to weigh cost, convenience, and patient preference against limited evidence when designing services.
Why the gaps matter—and where research is needed next
The review’s most striking limitation was its geographic focus. All included studies came from high-income countries, leaving a blind spot for regions like sub-Saharan Africa, South Asia, and the Middle East. “Findings may not apply everywhere,” the authors cautioned, pointing to differences in healthcare infrastructure, provider training, and patient needs across settings.
Public health experts have long highlighted disparities in rehabilitation access, particularly in low-resource areas where in-person services are scarce. The new analysis underscores the need for studies in these regions to determine whether telerehabilitation—or other delivery models—could bridge gaps. “More research is essential to guide policy decisions,” the report stated, adding that new studies should prioritize diverse populations and real-world outcomes.
What comes next for rehabilitation policy?
Health systems face a critical choice: how to organize rehabilitation services when evidence is incomplete. The review’s authors recommended that policymakers consider three key priorities:
- Expanding research in low- and middle-income countries to test whether delivery models like telerehabilitation work outside high-income settings.
- Investigating patient-centered outcomes beyond clinical measures, such as quality of life, cost-effectiveness, and long-term adherence.
- Developing standardized guidelines for rehabilitation delivery, accounting for local resources and cultural factors.
For now, the analysis suggests that telerehabilitation holds promise for stroke recovery but cannot yet replace in-person care universally. Meanwhile, the lack of evidence on provider types or care settings leaves health systems navigating uncharted territory—with decisions often driven by availability rather than proven effectiveness.
Key questions answered by the review
Why does telerehabilitation show promise for stroke survivors?
According to the analysis, studies found that video-based or phone-delivered rehabilitation produced similar improvements in mobility, arm function, and mental well-being as in-person care. However, researchers emphasized that more high-quality trials are needed before widespread adoption.
Does it matter who provides rehabilitation—doctors or specialists?
The review found no meaningful difference in health outcomes when care was delivered by doctors versus other trained professionals like physiotherapists. The data did not address whether patient satisfaction or access varied by provider type.
Can rehabilitation happen just as effectively at home?
A few small studies compared home-based care to traditional settings, reporting similar results, but the evidence was too limited to draw firm conclusions. The review rated confidence in these findings as low.
Are these findings applicable worldwide?
No. Nearly all studies were conducted in high-income countries, leaving major gaps in understanding how delivery models work in Africa, Southeast Asia, and the Eastern Mediterranean. The authors warned that results may not apply globally.
Sources and methodology
The analysis was part of a larger study on rehabilitation and health policy, led by researchers affiliated with [original study source—if identifiable; otherwise omit]. The team searched three major research databases for systematic reviews on rehabilitation delivery, identifying 25 but using data from only five for this project. The evidence cutoff date was November 17, 2024.
