A feasibility study of a randomised controlled trial comparing fall prevention using exercise with or without the support of motivational interviewing

摘要

Objective The aim of this investigation was to study the feasibility of a randomised controlled trial (RCT) based on a multicentre fall prevention intervention including exercise with or without motivational interviewing compared to standard care in community-living people 75years and older. Method The feasibility of a three-armed, randomised controlled trial was evaluated according to the following: process, resources, management by questionnaire, and treatment outcomes. The outcome measures were fall frequency, physical performance and falls self-efficacy evaluated after three months. Twelve physiotherapists conducted the measurements and treatments and responded to the questionnaire. The first 45 participants recruited to the ongoing RCT were included: 16 individuals in the Otago Exercise Program group (OEP), 16 individuals in the OEP combined with motivational interviewing group (MI), and 13 individuals in the control group. The study was conducted from November 2012 to December 2013. Results The feasibility of the study process, resources and management reached the set goals in most aspects; however, the set goal regarding the MI guide and planned exercise for the participating older people was not completely reached. No significant differences were found between the groups regarding the outcome measures. Conclusion This study confirmed the acceptable feasibility for the study protocol in the ongoing RCT. Highlights ? Feasibility in this study was sufficient and evaluated from the physiotherapist's perspective. ? Motivational interviewing takes time to learn and implement in trials. ? The physiotherapists were well motivated to perform the interventions.
