This review examines how a simple test called the head-up tilt test might help diagnose and manage ME/CFS. In this test, a patient lies flat and is then tilted upright while doctors measure heart rate and blood pressure changes. The review discusses whether these measurements could reveal problems with how the body controls blood pressure and heart function in ME/CFS patients.
Orthostatic intolerance and autonomic dysfunction are significant contributors to disability in ME/CFS. A standardized diagnostic test like the head-up tilt test could help clinicians objectively identify these physiological abnormalities and potentially guide treatment approaches, improving recognition and management of a key mechanism underlying ME/CFS symptoms.
As a review article, this study does not provide new experimental evidence or large-scale validation data. It cannot prove that the head-up tilt test is definitively diagnostic for ME/CFS or establish the prevalence of orthostatic intolerance in ME/CFS populations—it synthesizes existing evidence rather than generating new clinical data.
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 →
