Summary

Inspiratory Muscle Training is tracked by OSMF as an investigational option for ME/CFS; no regulator has approved it for this indication, and most post-viral conditions have no approved disease-modifying therapy at all. ClinicalTrials.gov lists 1 registered trial linking Inspiratory Muscle Training to ME/CFS: 1 has completed. None of the registered studies carries a drug-development phase label, which is typical for behavioural, device and supplement protocols. It plans or enrolled 40 participants. Registered activity dates to 2022. The literature layer holds 6 publications for this pair: 6 PubMed search records. Publication years run from 2023 to 2026. Items here are search-derived or curated references rather than classified trial reports; treat them as leads to read, not as graded evidence.

Myalgic Encephalomyelitis / Chronic Fatigue Syndrome is tracked on the OSMF post-viral programme alongside ME/CFS, Long COVID, POTS and MCAS. Across the programme, 191 candidate agents are logged for ME/CFS, most of them preliminary; this page isolates the record for one of them.

How the evidence score is calculated
  • Each registered trial scores by status (recruiting / active / enrolling 3, completed 2.5, not yet recruiting 2, unknown 1, terminated / withdrawn / suspended 0.5) plus a phase bonus (phase 3-4 +2, phase 2 +1, phase 1 +0.5). The trial component is capped at 30.
  • Each literature item scores by design (Cochrane review 5, meta-analysis 4, systematic review 3, RCT 3, clinical trial publication 2, curated reference 1.5, other PubMed record 1). The literature component is capped at 30.
  • The existing evidence tier adds 15 (A / Strong), 10 (B / Moderate), 5 (C / Preliminary) or 0 (D / Anecdotal).
  • Agents approved for any indication (max clinical phase 4) add 5, because an approved agent has an established safety profile that lowers the barrier to repurposing trials.
  • The score ranks what has been studied, not what works. It does not read effect sizes or directions of effect.
