PURPOSE: (1) To examine the intra-rater, inter-rater and test-retest reliability
of Jacket Test times with 28 people with chronic stroke.
(2) To determine the
correlation of Jacket Test time with stroke-specific impairments. (3) To
construct the optimal cutoff time for the Jacket Test that best discriminated 28
people with stroke from 30 healthy older adults.
METHODS: The Jacket Test
completion times were measured along with the Fugl-Meyer Upper Extremity
Assessment, hand grip strength, 5-times Sit-to-stand test, Berg Balance Scale and
timed "up and go" test, and Community Integration Measure using the
cross-sectional design. RESULTS: The Jacket Test completion times showed
excellent intra-rater, inter-rater and test-retest reliability (Intra-class
Correlation Coefficient = 0.781-1.000). The unaffected-side Jacket Test times
were significantly correlated with FMA-UE score, affected hand grip strength,
Berg Balance Scale score, timed "up and go" test times and Community Integration
Measure score. The affected-side Jacket Test times significantly correlated with
affected hand grip strength. The cutoff time of 18.33s in affected side and
18.38s for unaffected side (sensitivity 96.7%; specificity 85.7-96.4%) was used
to best discriminate the subjects with stroke and healthy older adults.
CONCLUSION: The Jacket Test is a reliable and valid measure tool in clinic to
evaluate the upper extremity function in people with chronic stroke. Implication
for rehabilitation The Jacket Test completion times has excellent intra-rater,
inter-rater and test-retest reliabilities in patients with chronic stroke. The
Jacket Test completion times significantly correlated with motor functions of the
upper limbs. The Jacket Test completion times of 18.33s in affected side and
18.38s for unaffected side (sensitivity 96.7%; specificity 85.7%-96.4%) was found
to be the most representative for discriminating chronic stroke survivors and
healthy older adults. The Jacket Test is a reliable and valid measuring tool to evaluate the upper extremity function of people with chronic stroke.
