Abstract

BACKGROUND:

Activities and their importance for daily living vary widely between patients. Patient-specific measurement of functional status means that the evaluation is focused on activities that an individual patient selected as main complaints.

OBJECTIVE:

To develop and to evaluate a patient-specific approach for measuring functional status in low back pain.

STUDY DESIGN:

A cohort of 150 patients was measured at baseline and 12 weeks later.

METHODS:

The feasibility of the patient-specific approach was evaluated in patients with nonspecific low back pain. We used effect size statistics to evaluate responsiveness in terms of sensitivity to change and specificity to change.

RESULTS:

The selection procedure for the main complaint was feasible but labor intensive. The patient-specific approach was able to detect changes in complaints that were highly relevant for the patients. The patient-specific approach appeared to be more sensitive to change but less specific to change compared with other instruments.

CONCLUSIONS:

On the basis of this study it would be valuable to apply the patient-specific approach in future studies, also with the aim of further evaluation. In the meantime a number of practical problems of the method need to be resolved.
