Quick Summary
This paper discusses how chronic fatigue and exhaustion affect people undergoing rehabilitation for various medical conditions. The authors reviewed how fatigue is defined, how often it occurs in different patient groups (from 50-90% depending on the condition), and whether rehabilitation can help improve it. They suggest that fatigue symptoms do improve somewhat with rehabilitation, though some symptoms can remain.
Why It Matters
This study is relevant to ME/CFS because it highlights how pervasive and disabling fatigue is across multiple medical and psychiatric rehabilitation settings, and it calls for systematic classification and assessment tools for fatigue as a core rehabilitation outcome. Understanding fatigue as a functional impairment rather than solely a psychiatric symptom may help clinicians better recognize and measure post-exertional malaise and exhaustion in ME/CFS patients.
Observed Findings
- Fatigue symptoms were reported in 50-90% of rehabilitation patients depending on indication type, with highest prevalence in psychosomatic rehabilitation cohorts.
- Neurasthenia diagnosis agreed with patient-reported symptoms in approximately 90% of cases assessed by general practitioners.
- Neurasthenia resulted in work disability more frequently than other psychosomatic or somatization diagnoses.
- Fatigue symptoms showed measurable improvement during rehabilitation, though pathological findings remained evident on follow-up examination.
- Fatigue symptoms were observed in up to 50% of orthopedic rehabilitation patients and in markedly severe forms in rheumatology patients.
Inferred Conclusions
- Chronic fatigue is a significant rehabilitation outcome that occurs across diverse medical and psychiatric conditions and warrants systematic clinical classification.
- Rehabiliation interventions can produce partial improvement in fatigue symptoms, suggesting these symptoms are responsive to integrated psychomedical treatment.
- Systematic assessment tools and ICF-based classification are needed to better measure and compare fatigue across rehabilitation populations.
- Fatigue in rehabilitation should be understood as both a psychovegetative and medical-behavioral phenomenon requiring adapted interventions.
Remaining Questions
What This Study Does Not Prove
This study does not establish the underlying biological mechanisms of chronic fatigue, nor does it directly address ME/CFS as a distinct diagnosis. The study is retrospective and consensus-based rather than prospective or experimental, so it cannot prove causation or establish whether fatigue improvements are sustained long-term. The prevalence figures are descriptive rather than based on rigorous epidemiological methodology.

About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →
