OBJECTIVE: To evaluate the test-retest reliability of the Shape/Texture
Identification test (STI-testTM) in persons with chronic stroke. DESIGN: A test-retest design. SETTING: University hospital outpatient setting.
PARTICIPANTS: Forty-five persons (mean age 65 years) with mild to moderate
impairments in the arm and hand > 6 months post stroke. INTERVENTIONS: Not
applicable. MAIN MEASURE: The STI-testTM was used to assess active touch of the
hand. It consists of two subtests: identification of shapes and identification of
textures, each in three different sizes. Both hands were assessed twice, one week
apart. The reliability of the data was evaluated with weighted Kappa statistics
and the Svensson rank-invariant method (percentage agreement, systematic and
random disagreements). RESULTS: The median total score of the STI-testTM was 5
points (min-max 0-6 points) for the more affected hand and 6 points (min-max 3-6
points) for the less affected hand at both test occasions. The weighted Kappa
coefficient was 0.94 for the more affected hand and 0.55 for the less affected
hand. The percentage agreement for the more affected hand was 69% for the subtest
shapes and 82% for the subtest textures, and for the less affected hand 62% and
91%, respectively. There were no systematic or random disagreements for any of
the subtests. CONCLUSION: The STI-testTM is reliable to assess active touch of
the hand after stroke.
