The Bateman Horne Framework: Screening and Managing PEM in ME/CFS and Fibromyalgia
The Bateman Horne Center, co-founded by internist Lucinda Bateman, who helped write the 2015 IOM/NAM diagnostic criteria for ME/CFS, frames post-exertional malaise (PEM) screening as the starting point for management: a NASA Lean Test (or similar) to screen for orthostatic intolerance, symptom-contingent pacing that never pushes through PEM, and sleep restoration prioritized early. This is informational, drawn from the Center's own published clinical guidance, and complements, never replaces, care from your own physician. Graded exercise or push-through approaches are explicitly not part of this framework.
Ask your clinician about a NASA Lean Test or similar orthostatic screening A single in-office or at-home screening test, physician-guided
Orthostatic intolerance overlaps heavily with ME/CFS, and identifying it changes what pacing and lifestyle advice actually apply to you.
Ask by name for a NASA Lean Test, a 10 minute active stand, or a tilt table test. If you are still dismissed or not taken seriously, it is reasonable to ask for a referral to a clinician experienced in ME/CFS or orthostatic intolerance, or to seek a second opinion One conversation; bring written symptom and heart-rate records if you have them
Being disbelieved is one of the most-reported experiences in this illness. An objective orthostatic measurement gives the conversation something measurable to work from, and ME/CFS has had formal diagnostic criteria since the 2015 IOM/NAM report, so it is a recognised diagnosis, not a judgement about the patient.
Base activity on how your body responds that day, staying under the threshold that triggers post-exertional malaise Ongoing, reassessed daily; never a fixed, escalating exercise schedule
The Center's framework is explicit that pacing is symptom-contingent, not a graded-exercise program; pushing through on a good day is what triggers PEM crashes.
Prioritize addressing unrefreshing sleep with your clinician as an early step, not an afterthought Ongoing, physician-guided
Unrefreshing sleep is a core diagnostic feature of ME/CFS in the Center's framework, and poor sleep compounds every other symptom.
Some ME/CFS patients and clinicians use CoQ10 or D-ribose alongside the above, graded honestly as preliminary, not established Discuss with your clinician; no dose prescribed here
Human evidence for D-ribose specifically in ME/CFS is thin and mixed (small, largely uncontrolled studies), so this is presented as what some patients and clinicians try, not as a proven intervention. Never a substitute for the pacing and sleep steps above.
The Bateman Horne Center's guidance reflects the same diagnostic logic as the 2015 IOM criteria Bateman helped write: post-exertional malaise, a delayed, disproportionate worsening of symptoms after exertion, is the defining feature, so any management approach has to be built around not triggering it.

Is this for you
- People newly diagnosed with ME/CFS or fibromyalgia looking for a framework, not a cure claim
- Anyone whose current care has not screened for orthostatic intolerance
Cautions
- Informational only, complements but never replaces your own physician's care
- Never graded exercise or push-through; pacing is symptom-contingent
- Only a clinician can diagnose ME/CFS or run orthostatic testing
