Augmentation is defined as below:
RLS appear 2 hours earlier than the pre-treatment. Symptoms become severer than the pre-treatment. Symptoms which start after less time at rest than they did before treatment. The RLS extend to other sites (e.g. arm and trunk).

Intervention / Treatment |
---|---|
Experimental: ropinirole CR-RLS
Subjects will orally take ropinirole CR-RLS tablet(s) once daily 1-2 hours before the onset of RLS symptoms at about the same time of the day.
The time of taking ropinirole must be after 16:00.Adjustment of the Ropinirole CR-RLS tablets should be completed after the Week 1 visit up to the Week 10 visit.
The dose will be increased at intervals of at least one week until sufficient efficacy is obtained (use "much improved" as a guide) without safety problem.
Dose escalation will start at the initial dose 0.5 mg/day to 1 mg/day; after 1 mg/day, the dose will be increased by 1 mg/day to the maximum 6 mg/day.

Each component score ranges from 0 (no difficulty) to 3 (severe difficulty).
The domain scores are totaled to produce a global score (range of 0-21).
A PSQI global score > 5 is considered to be suggestive of significant sleep disturbance.
