Umeå University173 enrolled

Overview

The purpose is to evaluate reach, effects and costs effectiveness of a mobile, fall prevention exercise program for older community-dwelling persons (70+ years) in a pragmatic trial. Information about the study will be spread to the population by letters sent to all households with someone aged 70 years or older, presentations for senior organizations, advertisements on busses, health care centers, senior centers and in social media. Participants will be recruited in one municipality through the website (www.ostersund.se/sakrasteg) including information about the aim and procedures of the study. If seniors themselves judge that they are eligible to participate in the study, they can register by providing their email address. After baseline assessment, through self-reports in a digital survey, participants will get access to the mobile health application. The estimated target group is 2600 persons. Recruitment will be ongoing for six months. The intervention is delivered through the Safe Step application, developed in co-creation with seniors and researchers. Safe Step provides a large repository of evidence-based balance and strength exercises in video formats alongside falls preventive information and advice. With the Safe Step app the user can compose an individualized exercise program suitable for their needs. To help the user adhere to the program a set of behaviour change techniques is provided by the program. The user can set their own goals, get reminders and positive feedback form a virtual physiotherapist, and follow their own progress. Advice on how to integrate the exercises into everyday activities is also offered. The participants will exercise on their own with the help of the application for one year, with a recommendation of 30 minutes at least 3 times/week. In addition, participants will get monthly emails with falls preventive information in short videos, they will also be asked to report any falls by responding to a survey attached to the message. In order to maximize reach and to support participants to get started using the Safe Step application, technical support and group-based exercise will be provided. The interventions will last for 1 year with follow up assessments at 3, 6, 9, and 12 months in addition to the monthly fall reports. Effects and cost effectiveness will be evaluated in relation to a previously registered RCT NCT03963570.

Interventions

Digital exercise program with supportBEHAVIORAL

The Safe Step application includes an instruction movie on how to create and progress an individual exercise program. The exercises, presented in video format, are organized into 10 groups with a main focus on balance (3 groups), lower-limb strength (4 groups), and gait/step (3 groups). The participants choose an exercise suitable for their needs from each group to compose a program of ten exercises. Participants use the app to plan their exercises, set reminders, register their exercise, and view statistics. A virtual physiotherapist delivers motivational messages and feed-back. At the end of each month the participants receive an email asking them to report any falls during the past month in a short digital survey. These messages also contains a new video with general falls prevention information. Technical support will be provided weekly at senior meeting sites. Try-out group exercises (step 1-3) will be provided by a local wellness association (Friskis\&Svettis)
