Purpose: The purpose of this paper is to critically review published research in order to evaluate the evidence surrounding the provision of video or DVD technology to promote patient compliance with home exercise or health programmes.
Method: A literature search of the MEDLINE, CINAHL and Cochrane databases was undertaken. Critical appraisal of selected studies was undertaken using a previously validated tool. Inclusion criteria were: research related to DVD or videotape technology to improve compliance; published in peer-reviewed journals and full-text English language articles. Compliance was the main outcome measure.
Results: Eleven eligible studies were reviewed. All but one, which used a before-after design, were randomised controlled trials. Study quality tended medium to high in the critical appraisal scoring system, but an overall low quality on the Jadad score for randomisation; with only one study from 11 scoring well on both these measures. Research into the use of video or DVD showed mainly positive effects on compliance; however, methodological issues limit clinical applicability.
Conclusions: Future well-designed randomised controlled trials with adequate sample sizes and reliable outcome measures will provide clearer evidence into the effectiveness of this technology in improving home exercise or health programme compliance, particularly for rural and remote populations.
