- Brief summaryRationale:
Sick leave in patients with chronic whiplash associated disorders (WAD) is an important problem for society. 15-30% Of the patients continue to experience serious symptoms after the first six months. Pain related disability is a complex multidimensional construct, influence by biological, psychological and social factors. Valid measurement of disability is challenging. Self reported disability and performance based disability are assumed to be related which each other but distinct. However, this has not been tested in patients with WAD.

Objective:
To investigate the relationship between self-reported disability, performance based disability and psychological factors in patients with WAD.

Study design:
Cross-sectional observational study.

Study population:
Fifty patients with complaints of chronic whiplash (WAD I-II).

Main study parameters/endpoints:
The “Neck Disability Index” (self-reported disability) and the Neck Specific version of the Functional Capacity Evaluation for neck complaints (performance based disability).

Nature and extent of the burden and risks associated with participation, benefit and group relatedness:
The risk of the study is negligible. All test are considered safe for the patients and with a low burden.
