- The objectives of the study were, in a working population, to standardize and evaluate a set of clinical tests on impairment level related to the low back with reference to intra- and inter-rater reliability. The study was undertaken in two steps. In step 1, 15 tests were examined for inter-rater reliability by three pairs of physiotherapists and for intra-rater reliability by one physiotherapist. Intra-rater reliability was acceptable (kappa > 0.40) for 14 of the 15 tests. Inter-rater reliability was acceptable for 7 of the 15 tests. In step 2, the tests, indicating a non-acceptable inter-rater reliability (kappa less than or equal to 0.40) were further standardized and re-tested by two of the physiotherapists. This further standardization procedure resulted in an acceptable interrater reliability for all of these tests. Clinical tests of a working population should preferably be performed by the same rater. However, when tests are performed by different raters, it is suggested that test procedures should be regularly standardized, and in pain provocation tests, the magnitude of the applied pressure should be checked regularly and compared with co-raters, in order to improve inter-rater reliability.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Results of reliability studies on physical performance tests are often conflicting. The main purpose of this study was to analyse the inter-rater reliability and between-days repeatability of physical performance tests on a female working population. Twenty-two nursing aides/ assistant nurses were tested twice, with, on average, a 5-day interval. Seventeen of these were tested again, after an average of 16 days. Isometric endurance of the neck flexors, abdominal, back and shoulder muscles, standing balance and two lifting tests (lumbar and cervical Progressive Isoinertial Lifting Evaluation {PILE} tests) were evaluated. Intra-class correlation coefficient (ICC), standard error of measurement (SEM), coefficient of variation (CV) and limits of agreement (LOA and LOAratio) were calculated. The inter-rater reliability was high for all tests. The between-days repeatability, however, differed depending on the statistical method employed. Only one of the tests - the cervical PILE test - was considered reliable between-days. Muscular endurance tests, the lumbar PILE test and standing balance tests, as performed in this study, did not give reliable between-days results.
