- Registration Number
- NCT04161625
- Lead Sponsor
- Umeå University
- Brief Summary
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.

Group Intervention Description Safe Step - digital exercise program Digital exercise program with support All included participants will receive full access to the Safe Step application and create their own individual program of strength and balance exercises. During 1 year the participants are recommended to exercise at least 30 minutes, 3 times a week and continuously progress their program. In addition they will every month receive an email with general falls prevention information in a short video. Additional support to promote reach and exercise adherence will be provided in the format of technical support and try-out group exercises throughout the recruitment period.
- Primary Outcome Measures
Name Time Method Reach 12 months The number of participants in relation to estimated size of total target population
- Secondary Outcome Measures
Name Time Method Participation in technical support sessions 12 months Number of participants participating in technical support sessions
Participation in try-out group exercises 12 months Number of participants participating in try-out group exercise sessions
Self-rated balance Change; Baseline, 3 months, 6 months, 9 months, 12 months Answering the question: "How do you perceive you balance?" on a 5-level ordinal scale ranging from "very good" to "very bad".
Falls efficacy Change; Baseline, 3 months, 6 months, 9 months, 12 months Falls Efficacy Scale-International (FES-I). Concerns about falling is rated for 16 activities (e.g. cleaning the house) on a scale from 1 (not at all concerned ) to 4 (very concerned ). Ratings for each of the 16 activities are summed to a total score ranging from 16 (no concern about falling) to maximum 64 (severe concern about falling)
Use of the information videos 3 months, 6 months, 9 months, 12 months Answering the question: "Have you watched the videos we sent you by e-mail during the last 3 months?" on a 4-level ordinal scale.
Sociodemographic characteristics age Baseline Reach of recruitment will be assessed in relation to age.
Self-rated leg-strength Change; Baseline, 3 months, 6 months, 9 months, 12 months Answering the question: "How do you perceive your leg muscle strength?" on a 5-level ordinal scale ranging from "very good" to "very bad".
Health related quality of life Change; Baseline, 3 months, 6 months, 9 months, 12 months Health related quality of life is assessed by the EuroQol 5 dimension 5 level self-report questionnaire (EQ-5D-5L).
The EQ-5D-5L descriptive system comprises the following 5 dimensions: mobility, self-care, usual activities, pain/discomfort, anxiety/depression, and a Visual Analogue scale (VAS). Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems, and extreme problems. A 1-digit number express the level selected for each dimension. The digits for 5 dimensions can be combined in a 5-digit number describing the respondent's health state. It should be noted that the numerals 1-5 have no arithmetic properties. The VAS records the respondent's self-rated health on a vertical, visual analogue scale (ranging from 0-100) with endpoints labelled "the best health you can imagine" and "the worst health you can imagine".Exercise adherence throughout the intervention 12 months Adherence to predefined minutes of 3x30 min/week reported continuously through an integrated exercise diary in the Safe step application and by self-report at follow up assessments.
Sociodemographic characteristics gender Baseline Reach of recruitment will be assessed in relation to gender.
Sociodemographic characteristics living conditions Baseline Reach of recruitment will be assessed in relation to living conditions).
Perceived Exertion Change; Baseline, 3 months, 6 months, 9 months, 12 months The Borg Scale of Perceived Exertion during the 30 second chair stand test, rated on a scale between 6 (none) to 20 (maximal exertion).
Self-rated improvements in leg-strength 12 months Answering the questions: "If you compare with when you started this study a year ago, how would you assess the muscle strength in your legs today?" on a 5-level ordinal scale ranging from "much better" to "much worse".
