Rehab is growing fast, but the demand behind it can be easy to miss until you see the employment, disability, and outcomes all at once. With $5.3 billion global revenue for physical therapy clinics in 2023 estimated alongside 2.5 million US patients using outpatient rehab services in 2021, the scale is clear yet uneven. And when early supported discharge can cut hospital days and stroke rehab can reduce mortality, the real question becomes what is driving these results across settings and populations.
Key Takeaways
- 3.3 million total employment in the US home health care services industry in 2023
- 2.1 million people employed in the US social assistance industry in 2023
- 0.7% annual average employment growth rate projected for US physical therapy and related workers from 2023 to 2033
- 65.0% of older adults in the US reported at least one limitation in activities of daily living in 2022
- 1.2 billion people globally live with a disability in 2019 (WHO); rehabilitation demand correlates with disability prevalence
- 4.5 million stroke events occur in the Americas each year (PAHO/WHO)
- $5.3 billion global market size for physical therapy clinics in 2023 (estimate by IBISWorld/industry databases)
- $3.1 billion global neurorehabilitation market size in 2022
- $1.9 billion global stroke rehabilitation market size in 2022
- 41% of healthcare organizations increased investment in digital health during 2022 (relevant to rehab programs using apps and remote monitoring)
- 36% of US clinicians reported using AI for clinical workflow tasks in 2023 (enables rehab triage and documentation automation)
- 46% of US adults are willing to use telehealth for rehabilitation services (survey-based)
- 0.8 fewer hospital days on average for patients receiving early supported discharge rehabilitation vs standard care (meta-analysis)
- 1.2 points average improvement in FIM score after inpatient rehabilitation compared with control groups in a systematic review (functional gain measure)
- 18% relative reduction in mortality for stroke patients receiving rehabilitation vs no rehabilitation in pooled analyses
Disability and demand are rising fast, and coordinated, digital and early rehab improves outcomes while reducing costs.

How We Rate Confidence
Models
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Single source
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Directional
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
Verified
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
