OBJECTIVE: To evaluate the reliability and discriminative ability of
a test battery consisting of 7 tests designed for the
assessment of functional limitations in patients with
fibromyalgia syndrome (FMS).
METHODS: The intrarater
reliability of the test battery was evaluated for 15 women
with FMS. Interrater reliability was calculated on 4 tests
separately. Fifteen healthy women constituted a reference
RESULTS: The intrarater coefficient of variation was <
8% for the shoulder range of motion tests, chair test, and
6-minute walk test, and < 21% for the shoulder endurance test,
with correlation coefficients above 0.80 for all tests. Kappa
was 0.70-0.80 for the hand-to-scapula tests. The interrater
coefficient of variation was < 5% for shoulder range of
motion. The performances of the FMS patients were
significantly decreased in comparison with healthy subjects in
all the tests except for the hand-to-scapula movement.
CONCLUSIONS: All but 1 of the selected 7 tests were considered
to possess acceptable intrarater reliability for use in FMS in
clinical physical therapy practice.
