I’m only seeing people with ME or Long Covid sharing this. If you’re not affected, can you please read it & share? Ableist propaganda goes viral all the time, which encourages outlets to publish more of it. Can we please make the truth go viral instead?

It's 2025 and we are still using the 6 minute walking test as a primary outcome measure in long covid clinical trials. Yikes.

Can we try not to undermine all the international guideline processes? I'm so much done with the continued propagation of exercise as a cure for PEM. No, tolerance will NOT increase even if you stay within your energy limits. PwME have been saying this for DECADES.

A red poster with the hashtag #MillionsMissing at the top. Below that the letters SOS spelled out with 18 selfies of a white Mexican woman lying down, often in the dark and wearing an ice hat, sometimes with a beloved orange cat. 
Below that some key facts: 
- M.E. has one of the lowest Quality if Life measurements of any disease 
- There are zero FDA approved drugs for ME 
- NIH M.E. funding is extremely low relative to disease burden 
- Even this limited funding is currently at risk

Why can't we just accept that exercise is not a cure for PEM? It keeps popping up, often disguised as pacing but it's actually graded exercise. The whole point of GET is that it uses super tiny increments. Like 30s-1min. That's still unsafe and puts people at risk. Please stop pushing GET!

If exercise worked we'd genuinely know by now Studies that claim success through 'small wins' - that is essentially bias - does not mean exercise is the answer But, unfortunately, we have a research community who cannot move on from lifestyle interventions

If a researcher or clinician is still invested in exercise or 'pacing up' it shows: 👉 devastating alienation from the patient experience 👉 wilful disengagement from the scientific research 👉 career, ideology & 'being right' is more important than the patient #wrongparadigm
