Upper Extremity Motor Learning among Individuals with Parkinson's Disease : A Meta-Analysis Evaluating Movement Time in Simple Tasks

الملخص EN

Motor learning has been found to occur in the rehabilitation of individuals with Parkinson's disease (PD).

Through repetitive structured practice of motor tasks, individuals show improved performance, confirming that motor learning has probably taken place.

Although a number of studies have been completed evaluating motor learning in people with PD, the sample sizes were small and the improvements were variable.

The purpose of this meta-analysis was to determine the ability of people with PD to learn motor tasks.

Studies which measured movement time in upper extremity reaching tasks and met the inclusion criteria were included in the analysis.

Results of the meta-analysis indicated that people with PD and neurologically healthy controls both demonstrated motor learning, characterized by a decrease in movement time during upper extremity movements.

Movement time improvements were greater in the control group than in individuals with PD.

These results support the findings that the practice of upper extremity reaching tasks is beneficial in reducing movement time in persons with PD and has important implications for rehabilitation.
