Test-retest reliability of the Isernhagen Work Systems Functional Capacity Evaluation in @entity1 with XXXX .

@entity1 @entity1643 @entity7166
The aim of this study was to investigate test-retest reliability of the Isernhagen Work System Functional Capacity Evaluation (IWS FCE) in a sample of @entity1 (n = 30) suffering from @entity1643 ( @entity1643 ) and selected for rehabilitation treatment. The IWS FCE consists of 28 tests that reflect work-related activities like lifting, carrying, bending, etc. In this study, a slightly modified IWS FCE was used. @entity1 were included in the study if they were still at work or were less than 1 year out of work because of @entity1643 . @entity1 ' mean age was 40 years, the duration of @entity1643 ranged between 5 and 10 years. Fifteen @entity1 (50%) were out of work for a mean of 17 weeks, and they all received financial compensation. Two FCE sessions were held with a 2-week interval in between. Means per session, 95% confidence intervals of the mean difference, one-way random @entity7166 ( @entity7166 ), limits of agreement, Cohen's kappa and percentage of absolute agreement were calculated where appropriate. An @entity7166 of 0.75 or more, a kappa value of more than 0.60 and a percentage of absolute agreement of 80% were considered as an acceptable reliability. Tests of the IWC FCE were divided into tests with and tests without an acceptable test-retest reliability on the basis of the kappa values, the percentage of absolute agreement and the @entity7166 values. Fifteen tests (79%) showed an acceptable test-retest reliability based on Kappa values and percentage of absolute agreement. Eleven tests (61%) showed an acceptable test-retest reliability based on @entity7166 values.
