- •
Concerns exist that the standard PLMS index does not reflect the truly periodic, but rather the number of all leg movements.
- •
A recently introduced alternative PLMS index more closely reflects the ‘genuine’ periodic portion of leg movements.
- •
We determined optimal thresholds to differentiate patients with RLS from controls concerning these indices.
- •
Thresholds were 15/hour for the standard index, 13/hour for the alternative index, and 0.5 for the periodicity index.
- •
The diagnostic accuracy of all indices for RLS was found to be high (83.2–85.5%).
