OBJECTIVES: To investigate the test-retest reliability of JTT in older patients
with Parkinson's disease (PD); and to compare the Jebsen Taylor Hand Function
Test (JTT) scores between PD and healthy subjects. STUDY DESIGN: Cross-sectional
comparative study. METHODS: Fifteen PD and fifteen healthy subjects performed the
JTT and the time taken to complete the JTT was recorded. RESULTS: Test-retest
reliabilities of JTT subtests and total score of both dominant and non-dominant
hand were good to excellent (ICCs = 0.77-0.97) except J5 checkers which had
moderate reliability. PD subjects required significantly longer time to finish
subtests and the whole JTT (p < 0.05), except the subtest J1 writing of dominant
hand that showed marginal significance (p = 0.059). CONCLUSION: JTT is a reliable
and easily available assessment tool for assessing the hand function of PD
subjects. PD subjects took a longer time to complete the JTT, suggesting that
they have deficits in gross and fine functional dexterity.
