- Variation of at least one level of the analgesic levels used compared to the baseline assessment for pain relievers.
- Variation of at least one level in frequency compared to the baseline assessment for physiotherapy sessions.
-
Minor criterion:
- Variation of the total daily dose compared to the baseline assessment for painkillers.
-
- Number of oxygen therapy sessions followed by the patient [ Time Frame: 7 and 10 months ]
