Outcome Measures
Primary Outcomes (1)
Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS)
To assess the motor symptoms, participants completed the official Chinese version of MDS-UPDRS.The MDS-UPDRS-III includes 33 items, with scores ranging from 0 to 132. The subscores of MDS-UPDRS-III, including (1) rigidity (item 3.3), (2) bradykinesia (items 3.2, 3.4, 3.8, and 3.14), (3) tremor (items 3.15-3.18), and (4) axial signs (items 3.9-3.13), were also used as the secondary outcomes in the following analyses.
On intervention Day 1, Day 10 and 1-month follow-up.
Secondary Outcomes (2)
emotional symptoms assessed by the HAMA
on intervention Day 1, Day 10 and 1-month follow-up
emotional symptoms assessed by the HAMD
On intervention Day 1, Day 10 and 1-month follow-up.
Study Arms (2)
real stimulation
ACTIVE COMPARATORParticipants will receive active tTIS for 10 days.
sham stimulation
SHAM COMPARATORParticipants will receive sham tTIS for 10 days.
Interventions
The total stimulation duration was 30 minutes, including a 30-second current ramp-up at the beginning and a 30-second ramp-down at the end.
Sham stimulation had only 30 seconds of current ramping-up and ramping-down at the beginning and end of the stimulation, respectively, to simulate the sensation of actual stimulation.
