Abstract

Purpose: There is limited understanding of the characteristics and evaluation of more affected hand dexterity loss in Parkinson's disease.

Methods: This observational study analysed baseline data from a cluster-randomised controlled trial.Participants (n = 582) completed the pegboard with their more affected hand, the Patient-Specific Index-Parkinson's Disease and Self-assessment Parkinson's Disease Disability Scale. Mean pegboard performance was summarised at each disease stage. To investigate known groups validity, we explor..
