What domains does the ALSFRS-R cover?

ALSFRS-R has 12 items across four domains: bulbar (speech, salivation, swallowing), fine motor (handwriting, cutting food, turning pages), gross motor (dressing, walking, climbing stairs), and respiratory (dyspnea, orthopnea, respiratory insufficiency).

How is ALSFRS-R used to determine NIV and PEG timing?

Respiratory subscore ≤9 or FVC <50% triggers NIV discussion. Bulbar subscore decline and weight loss guide PEG gastrostomy timing — ideally placed before FVC falls below 50% when anesthetic risk is lower.

ALS Functional Rating Scale (ALSFRS-R)

Measure functional decline in Amyotrophic Lateral Sclerosis using the Revised ALS Functional Rating Scale across speech, swallowing, handwriting, walking, and respiratory domains.
