What Does the Research Say?
The AI Evidence Gap: What Rehabilitation Research Is Missing
AI in rehabilitation is growing fast. But a systematic mapping of 240 studies reveals critical blind spots that every clinician should understand before trusting AI outputs.
Living Systematic Mapping Review
10.2%
of AI rehabilitation studies incorporated explainability for their algorithmic outputs. That means nearly 90% of the AI tools studied operate as black boxes whose reasoning cannot be readily explained to clinicians or patients.
The Gaps by the Numbers
No Comparator
50.8%
Over half of published AI rehab studies lack a comparator group entirely
External Validation
5.8%
Only this fraction of studies validated their AI models on external datasets
Supervised Learning
70.8%
Relied on supervised learning with small, single-type datasets limiting generalizability
Pediatric Tailoring
1%
Of AI interventions in pediatric rehab were tailored to individual participation needs
3 Takeaways for Your Practice
1
Evidence Appraisal
Treat AI Outputs as Hypotheses, Not Conclusions
With only 10.2% of studies incorporating explainability, AI tools in rehabilitation are probabilistic predictions, not deterministic conclusions. Apply the same evidence-based reasoning you use for any other clinical tool: verify claims, check sources, and maintain professional judgment.
2
Equity Awareness
Small Datasets Mean Bias Is a Real Risk
Most AI models use small, homogeneous training datasets. When applied to underrepresented populations, performance may degrade. Be especially vigilant when using AI tools with patients from demographics that are historically underrepresented in clinical research.
3
Advocacy Opportunity
Push for Transparency in the AI Tools Your Organization Adopts
Before your institution invests in AI tools, ask: Was it validated on an external dataset? Can it explain its recommendations? Was the training data diverse? These three questions alone will filter out tools that do not meet the evidence standard you would apply to any other clinical intervention.
