结局指标
主要结局
Tremor Research Group Essential Tremor Rating Assessment (TETRAS) Activities of Daily Living (ADL) Subscale
时间窗: Baseline to 7 days
Patient rating on a 5-point scale, from 0 (normal) to 4 (severely abnormal)
Patient Global Impression of Improvement (PGI-I)
时间窗: Baseline to 7 days
Patient rating of tremor improvement on a 7-point scale, from 1 (very much improved) to 7 (very much worse)
Clinical Global Impression of Severity (CGI-S)
时间窗: Baseline to 7 days
Physician rating on a 7-point scale, from 1 (normal) to 7 (amongst the most extreme tremor)
Clinical Global Impression of Improvement (CGI-I)
时间窗: Baseline to 7 days
Physician rating of tremor improvement on a 7-point scale, from 1 (very much improved) to 7 (very much worse)
Tremor Research Group Essential Tremor Rating Assessment (TETRAS) Performance Subscale
时间窗: Baseline to 7 days
A subset of 6 performance tasks will be rated by a physician for each upper limb separately. Each task will be rated from 0 to 4, indicating the increasing severity of tremor.
Movement Disorder Society Unified Parkinson's Disease Rating Scale (MDS-UPDRS)
时间窗: Baseline to 7 days
Physician rated MDS-UPDRS Part III on a 5-point scale, from 0 (normal) to 4 (severe)
Patient Global Impression of Severity (PGI-S)
时间窗: Baseline to 7 days
Patient rating on a 7-point scale, from 1 (normal) to 7 (amongst the most extreme tremor)
Tremor Power
时间窗: Baseline to 7 days
Assessed by device sensor.
Tremor Research Group Essential Tremor Rating Assessment (TETRAS) Modified Activities of Daily Living (mADL) Subscale
时间窗: Baselinen to 7 days
TETRAS mADL score is a composite sum of items 2 to 11 of the TETRAS ADL subscale and items 6 (bilateral) and 7 (dominant hand) of the TETRAS performance subscale (PS). TETRAS mADL score is calculated as the sum of all 12 items and ranges from 0 to 52.
