Brief summary
The overall aim of the study is to evaluate the effectiveness of a digital self-management exercise program in preventing falls in community dwelling older people. Participants will be recruited in Sweden through the website (www.sakrasteg.se) providing study information. On the website interested seniors will get information about the aim and procedures of the study as well as inclusion and exclusion criteria. 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 be randomized to either an exercise intervention or a control group in a 1:1 ratio. The investigators aim to include 1400 participants and recruitment will be ongoing continuously for one year. The exercise intervention is delivered through the Safe Step application, developed in co-creation with seniors and an interdisciplinary research team. Safe Step provides a large repository of evidence based exercises in video formats alongside falls preventive information and advice. With support of this application the user can compose an individualized exercise program with balance and strength exercises 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 during one year, with a recommendation of 30 minutes at least 3 times/week. In addition to the exercise intervention the participants will every month get an email 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. The exercise group will be compared to a control group that will receive the same information emails as the exercise group, but no individual exercise advice. The interventions will last for 1 year with follow up assessments at 3, 6, 9, and 12 month in addition the monthly fall reports. Due to the nature of the study, with no face to face contact, all outcome measures are self-reports and self-tests in digital surveys. The primary outcome is fall rate. The study follows the CONSORT guidelines and CONSORT EHEALTH criteria.
Interventions
BEHAVIORALSafe Step - digital exercise program
After receiving the Safe Step application the participants view an instruction movie on how to use the application to create and progress their own individual exercise program. The exercises, presented in video format, are organized into 10 predetermined groups with a main focus to improve balance (3 groups), increase lower-limb strength (4 groups), and improve gait/step (3 groups). The participants choose an exercise suitable for their needs from each group to compose a program of ten exercises. They can use the app to plan their exercises, set reminders, register their exercise, and view statistics of their progress. A virtual physiotherapist deliver motivational messages and feed-back. At the end of every month, of the 1 year intervention period, the participants will receive an email asking them to report any falls during the past month by answering a short digital survey. This message will provide a new video each month with general falls prevention information besides exercise.
BEHAVIORALControl group
Participants randomized to the control condition will only be given information. They will receive exactly the same email messages as the intervention group with falls prevention information and a request to report any falls. At the end of the 12 month intervention we will, in addition to the other questions, ask if they have started to do any exercises during the intervention period. After the 12 month follow-up assessment the control group will be offered the Safe Step application.

Masking description
All outcomes are self-reports and self-assessments by the participants and reported in digital surveys. Outcomes will not be influenced by any other outcome assessors. Data set will be blinded regarding group allocation (and the code for the groups will be held by a researcher not involved in the study) when performing analyses for main outcomes.
Intervention model description
This is a randomized controlled trial (RCT) comparing a digital exercise program with a control group. The intervention will last for 12 months with follow-up assessments at 3, 6, 9 and 12 months.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Fall rate | 12 months | Falls will be registered every month through a short digital survey, received by email, asking the participant if they had any falls during the last month. If answering yes a few additional questions about when the fall occurred, any resulting injuries and hospital visits will be asked. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| 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 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. |
| 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. |
| 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) |
| 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. . |
