[Test-retest reliability of the Purdue Pegboard test in drug on-phase for patients with Parkinson's disease]

ABSTRACT

Parkinson's disease [PD] is a common progressive neurodegenerative disorder, which its onset is later in adults and it's incidence increases in people aged between 55 and 60 years. Dexterity, because of it's role at upper extremity function and person independency in function, is assessed in rehabilitation. Purdue-Pegboard test often is used in rehabilitation clinical settings. The purpose of this study was to determine the test-retest reliability and practice effects of the Purdue Pegboard test in persons with PD. 24 PD patients aging 5- 89 of both sexes were non-randomly selected from rehabilitation clinics and hospitals of Tehran. A demographic questionnaire was used for documenting patient's general data and the Purdue pegboard test and a timer were used for determining of reliability. Each subtest was administered three times in a row. The time distance between test and retest was one week. The relative reliability in repeated measures was above 90% in different items of Purdue pegboard test in single and mean of testes in off phase, thus indicates an excellent reliability. The absolute reliability [SEM] was lower than 10% of maximum obtained scores at each subtest in one and three trial of test that indicates acceptable errors of measurement. The results of the present study indicate that Purdue Pegboard test is enough reliable in evaluating a manual dexterity of Parkinson patients in drug on-phase
