Repetitive finger movement and circle drawing in persons with Parkinson's disease.

Little is known regarding how repetitive finger movement performance impacts other fine motor control tasks, such as circle drawing, in persons with Parkinson's disease (PD). Previous research has shown that impairments in repetitive finger movements emerge at rates near to and above 2 Hz in most persons with PD. Thus, the purpose of this study was to compare circle drawing performance in persons with PD that demonstrate impairment in repetitive finger movement and those that do not.

Repetitive Finger Movement and Dexterity Tasks in People With Parkinson's Disease.

Background: Little is known regarding how repetitive finger movement performance, an assessment of bradykinesia (slowness of movement), is related to fine-motor dexterity tasks in people with Parkinson's disease (PD).

Objective: This pilot study examined the relationship between the performance of fine-motor dexterity tasks and repetitive finger movement in people with PD.

Method: Forty-six participants with PD completed an acoustically cued repetitive finger movement task (1-3 Hz).

The relationship between repetitive finger movement and quality of life in Parkinson's disease.

Background: Repetitive finger movement significantly impacts daily living activities, but there have been limited studies determining how repetitive finger movement impacts quality of life (QOL) in persons with Parkinson's disease (PD). The purpose of this study was to determine the relationship between impairment in repetitive finger movement and QOL in persons with PD.

Methods: Eighty-four participants with PD completed a repetitive movement task and the Parkinson's Disease Questionnaire (PDQ).

Repetitive finger movement performance differs among Parkinson's disease, Progressive Supranuclear Palsy, and spinocerebellar ataxia.

Background: Differentiating movement disorders is critical for appropriate treatment, prognosis, and for clinical trials. In clinical trials this is especially important as effects can be diluted by inclusion of inappropriately diagnosed participants. In early disease duration phases, disorders often have overlapping clinical features, such as impairments in repetitive finger movement, making diagnosis challenging.
