This week is a dose and a diary. Paid access is four weeks.
Log pain 0–10 at this sitting, then at 24 hours, 7 days, and 14 days. That is how a class knows whether anything changed. No outcome percent is published from this page.
Activity-limit 0–10 is a plain daily-life number. It is not the Oswestry Disability Index or Roland-Morris. Official ODI / RMDQ items are not on this site. Drop a licensed form at the disability-scale placeholder. Who uses The Back Class is unconfirmed.
Ungated. You do not need a membership cookie to come back on day 7. New saddle, bladder, bowel, or sexual-function change → emergency care, not more notes.
