RESUMO
PURPOSE: To compare the work-related limitations assessed using self-report, clinical examination and functional testing in patients with chronic low back pain (CLBP). METHODS: Work-related limitations of 92 patients were assessed using self-report, clinical examination and functional testing. To obtain the assessed limitations the patient (self-report), the physician (clinical examination) and a trained evaluator (functional testing) completed a scorings form about the work-related limitations of the patient. The Isernhagen Work Systems Functional Capacity Evaluation (IWS FCE) was used to obtain the functional testing results. A kappa value of more than 0.60, absolute agreement of more than 80% and ICC of more than 0.75 were considered as acceptable. RESULTS: Little agreement and correlation among self-report, clinical examination and functional testing were found for the assessment of work-related limitations. Self-reported limitations were considerably higher than from those derived from clinical examination or functional testing. Additionally, the limitations derived from the clinical examination were higher than those derived from the IWS FCE. CONCLUSION: Comparing self-report, clinical examination and functional testing for assessing work-related limitations in CLBP patients showed large considerable differences in limitations. Professional health care workers should be aware of these differences when using them in daily practice.

PURPOSE: To analyse test-retest reliability and stability of the Dutch language version of the Roland Morris Disability Questionnaire (RMDQ) in a sample of patients (n = 30) suffering from Chronic Low Back Pain (CLBP). METHOD: Patients filled out the Dutch language version of the RMDQ questionnaire twice, before starting the rehabilitation programme, with a 2-week interval. Intra Class Correlations (ICC), (one way random) was used as a measure for reliability and the limits of agreement were calculated for quantifying the stability of the RMDQ. An ICC of 0.75 or more was considered as an acceptable reliability. No criteria for limits of agreement were available. However, smaller limits of agreement indicate more stability because it indicates that the natural variation is small. RESULTS: The Dutch RMDQ showed good reliability, with an ICC of 0.91. Calculating limits of agreement to quantify the stability, a large amount of natural variation ( +/- 5.4) was found relative to the total scoring range of 0 to 24. CONCLUSION: The Dutch RMDQ proves to be a reliable instrument to measure functional status in CLBP patients. However, the natural variation should be taken into account when using it clinically.

OBJECTIVES: To establish inter- and intra-rater reliability of observations in a functional capacity evaluation. BACKGROUND: Functional capacity evaluations are used to assess a person's functional capacity as it relates to work. Lifting and carrying are important aspects of a functional capacity evaluation. An evaluator determines the patient's levels of effort through standardized observations. Questions remain with regards to the reliability of these observations. METHODS: Four healthy subjects were videotaped while performing two lifts and four carries with progressive loads. The videotape was scrambled randomly and viewed twice by 3 physical therapists and 2 occupational therapists. The evaluators determined the amount of effort it required (light, medium, heavy, and maximum). The inter- and intra-rater reliability of the observations was expressed by means of percentage agreement. RESULTS: Inter-rater reliability ranged 87-96%, intra-rater reliability ranged 93-97%. CONCLUSION: The results indicate that by means of standardized observations, therapists can reliably determine effort level during lifting and carrying in healthy subjects, and thus affirm the findings of other studies of similar design.

The objectives of this study were to establish test-retest reliability of lifting and carrying of a functional capacity evaluation (FCE) on two consecutive days and to verify the need for a 2-day protocol. A cohort of 50 patients (39 men, 11 women) with nonspecific low back pain were evaluated using a 2-day FCE protocol. Intraclass correlation coefficients (ICC) were calculated for weight lifted and carried. Predictive relationships between test and retest were explored by means of a regression analysis. The results of ICC were lifting low 0.87, lifting overhead 0.87, and carrying 0.77. Performances on day 2 were on an average 6-9% higher. Other than the amount of weight handled on day 1, no variable was found to predict performance on day 2. It was concluded that test-retest reliability of lifting and carrying was good, and the need for a 2-day protocol could not be confirmed.

This exploratory study attempted to estimate the severity of health complaints and disabilities in patients supplied with foot orthoses for degenerative foot disorders in the Netherlands. Information on the severity and the distribution of the complaints in these patients is important to acquire insight in the problems which these patients experience, and moreover is essential for further research, especially for evaluating effects of patients undergoing foot orthosis treatment. Patients with degenerative foot disorders aged 18 years and over were recruited from nine orthopaedic workshops over a period of three months in 2000. One hundred and twenty-two (122) patients were included in the study. Two approaches were used to obtain data. Firstly, shoe technicians and orthotists inspected patients' feet and legs and interviewed them at their initial visit. Data on gender, age, height, weight, existing and prescribed orthotic devices were recorded on a report form. Secondly, patients were asked to fill in a questionnaire assessing type, location, frequency, intensity and duration of health complaints, and disability. Data indicate that females with degenerative foot disorders and foot orthoses are twice as common as men. Patients supplied with foot orthoses are twice as often overweight compared to subjects in the general population. Besides frequent and protracted pain there are also fatigue complaints, particularly in the feet and lower leg. Duration and frequency of the complaints suggest that these patients suffer from a chronic pain syndrome. In addition, the results indicate that the functional level of these patients is below that of the general population, in particular regarding physical activities.

Functional Capacity Evaluation's (FCE's) are designed to measure the functional capacity of injured workers. Static endurance tests are integrated aspects of FCE's. Little is known about the validity of the tests. In this study, three static endurance tests (overhead work, crouching and kneeling) of the Isernhagen Work Systems FCE are studied for ecological validity. By manipulating the environment in an experiment using three different conditions (normal, loud noise, high production requirement), the ecological validity of the tests was investigated. Results: the different conditions did not seem to influence the holding times, the perceived exertion and the productivity of the subjects. The results are discussed and it is concluded that the three static endurance tests meet conditions of ecological validity. In order to be able to state that the tests of the IWS FCE are ecologically valid, more research is needed to enable a generalization.
RESUMO
Points of view of the assessment and treatment of chronic work-related disorders in a Dutch university rehabilitation setting are described. After a general introduction in which the basic philosophy is outlined, medical issues as well as issues regarding two treatment programs and the evaluation of functional capacity are described. The article ends with a brief description of current and future research programs.
