Jankovic Rating Scale for Hemifacial Spasm

Jankovic Rating Scale for Hemifacial Spasm (JRS) Probably the most widely cited. It consists of two subscores:

Severity score (0–4): 0 = No spasm 1 = Mild spasm (noticeable but not disabling) 2 = Moderate spasm (interferes with facial expression but not daily activities) 3 = Severe spasm (markedly impacts daily activities) 4 = Very severe spasm (continuous disabling contractions)

Frequency score (0–4): 0 = No spasm 1 = Occasional (less than once an hour) 2 = Intermittent (more than once an hour but not continuous) 3 = Frequent (continuous but with breaks) 4 = Continuous (no breaks)

✅ Final JRS score = Sum of severity + frequency (maximum 8)
