Comparison of self and proxy ratings for motor performance of individuals with Parkinson disease

Abstract

The impact of Parkinson disease (PD) has been examined in recent years by comparing self-ratings by individuals with PD and proxy ratings by caregivers, communication partners, and/or health care providers. However, the existing evidence is mixed with some researchers suggesting perfect agreement between rater groups while others suggesting differences among rater groups for motor performance of individuals with PD. The current study examined self and proxy perception of performance of individuals with PD for six motor characteristics (gait, rigidity, right and left bradykinesia, rest tremors, and perception of physical effort) based on Unified Parkinson Disease Rating Scale (UPDRS) motor tasks. Participants included 20 individuals with PD, 20 communication partners, and a trained rater. The study compared perceptual ratings and corresponding UPDRS scores as well as rater group differences for perceptual motor ratings. A series of Pearson Product Moment Correlations indicated significant relationship only between self-ratings for gait and rest tremors by individuals with PD and corresponding UPDRS scores (p<.05). Further, a multivariate analysis of variance was completed to compare rater group differences. Results indicated sig...Continue Reading

Basal ganglia in Parkinson's disease (MDS)

The basal ganglia is comprised of the neostriatum, the external and internal pallidal segments, the subthalamic nucleus, the substantia nigra pars reticulata, and the pars compacta of the substantia nigra. The basal ganglia circuitry is responsible for the correct execution of voluntary movements and is implicated in Parkinson's disease. Here is the latest research investigating the basal ganglia in Parkinson's disease.

Basal Ganglia

Basal Ganglia are a group of subcortical nuclei in the brain associated with control of voluntary motor movements, procedural and habit learning, emotion, and cognition. Here is the latest research.
