Is a videotape to change beliefs and behaviors superior to a standard videotape in acute low back pain? A randomized controlled trial.

BACKGROUND CONTEXT

Cognitive behavioral therapy has been used successfully in acute low back pain (LBP) treatment, but the use of a cognitive behavioral videotape as an adjunct to treatment has not been studied.

PURPOSE

To determine outcomes for patients with acute LBP receiving a videotape designed to change beliefs and behaviors compared with a standard instructional videotape.

STUDY DESIGN/SETTING: Randomized controlled trial; multidisciplinary clinic in an academic setting.

PATIENT SAMPLE

Consecutive subjects with less than 3 months of LBP. Of 224 eligible subjects, 138 participated and completed the initial questionnaires.

OUTCOME MEASURES

Oswestry Disability Index, Pain and Impairment Relationship Scale, Fear-Avoidance Beliefs Questionnaire; medical costs related to LBP and total medical costs incurred by participants during 1 year of follow-up.

METHODS

Subjects were randomly assigned to receive a behavioral videotape or a control videotape. Other than the videotape, usual care was provided to each patient.

RESULTS

No significant differences in any outcome measures or medical costs between the two groups at 12 months. However, baseline Vermont Disability Prediction Questionnaire was significantly lower in those who completed the entire study compared with those who did not complete the study.

CONCLUSIONS

Compared with a standard instructional videotape, a behavioral videotape did not change beliefs, outcomes, or costs over 1 year. Cost-effective behavioral interventions with high patient retention rates are needed, especially for those at greatest risk of high utilization of resources.
