This study aimed to identify the most sensitive clinical, patient-reported, and neurophysiological measures to detect short-term disease progression in untreated adult SMA patients. Amongst every clinician-reported outcomes (MFM, HFMSE, RULM) and patient-reported outcomes (MFIS, CMAP, MUNIX), the MFM was the most sensitive to short-term progression and most closely aligned with neurophysiological markers, supporting its use as primary outcome in clinical trials involving adult SMA patients.
