Test-retest reliability at 2 weeks was excellent (two-way random intraclass correlation coefficient > 0.90), and the individual item test-retest reliability showed good agreement, with a threshold weighted kappa >0.60 for all items. In individuals with the condition, tremor tends to occur while voluntarily maintaining a fixed posture against gravity (“postural tremor”) or while performing certain goal-directed movements (“kinetic intention tremor”).
