Exercise-based fall prevention programmes with strength and balance components have been shown to reduce the rate of falls, risk of falling, fractures and injuries. However, there is little evidence on the implementation of these programmes in real-world settings.
This study aims to assess the effectiveness of exercise-based fall prevention interventions on fall risk (physical performance and fear of falling) among community-dwelling older adults who are at risk of falling in Singapore. A secondary aim is to assess the effectiveness of the programme on other health outcomes. The study will also evaluate the programme implementation from 3 perspectives of older adults, implementers and community partners.
Two exercise-based fall prevention programmes (Otago Exercise Programme, OEP and the Stepping On Programme, SOP) have been shown to be effective to prevent and reduce falls in primarily non-Asian settings. The Otago Exercise Programme is a single component intervention that has been shown to reduce fall rate among older adults by 35%. The OEP is a group-based exercise programme based on strength and balance components. The Stepping-On Programme is a multi-component intervention that has been shown to reduce fall rate by 30%. The SOP consists of group-based series of weekly sessions to teach fall prevention strategies to community-dwelling older adults. Sessions comprise of strength-balance exercises and classes based on adult learning principles.
However, there is little evidence of the effectiveness, feasibility and acceptability of locally-adapted community fall prevention interventions. Furthermore, studies on the effectiveness of fall prevention interventions among Asian populations are less robust due to the lack of well-designed studies with adequately powered sample sizes.
In this study, exercise-based fall prevention programmes will be implemented based on geographic region where participants living in the North region will receive the modified SOP and participants in the Central region will receive the modified OEP.

| Exercise-based fall prevention intervention (Modified Otago Exercise Programme and Modified Stepping On Programme) | Other | The modified OEP is a group exercise programme that consists of progressive strength and balance exercises led by trained exercise leaders (fitness instructors or health coaches). The supervised sessions will be conducted twice a week (1 hour each) for 7 weeks. Participants will be given an exercise booklet and encouraged to exercise at home. The modified SOP is a group fall prevention programme that consists of exercise sessions and discussions on various falls prevention aspects facilitated by a trained programme leader and supported by programme facilitators and peer facilitators. The supervised sessions will be conducted once a week (2 hours each) for 7 weeks. Participants will be given homework and encouraged to exercise at home. In addition, there will be an optional home visit (Week 11), a 1-hour booster session (Week 19) and a telephone call (Week 31). |

This is a stepped-wedge cluster randomized trial in which there will be a sequential crossover of clusters from the waitlist control to the intervention period where the sequence of crossover is randomized. The clusters are defined as groups with at least 5 participants. Each of the North and Central regions will have 6 clusters.
The intervention will be sequentially rolled out to 12 clusters that are randomized to 6 time periods (sequences). Each sequence has 6 steps where one step has a duration of 8 weeks. The intervention will be rolled out sequentially to 2 clusters (1 North, 1 Central) at every step until all 12 clusters have received the intervention by the end of the study. Each cluster will have 1-3 community sites and minimum 5 participants. Outcome assessors will be blinded to sequence allocation.

| Difference in Fear of Falling Between Intervention and Control Blocks |
Measured using the 16-item Falls Efficacy Scale International (FES-I). The score ranges from 16 to 64, with a higher score indicating a greater fear of falling. |
| Data will be collected at baseline and immediately after each step as this is a stepped-wedge analysis. |
Measured by asking "In general, how would you say your health is?" |
| Data will be collected at baseline and immediately after each step |
| Health-Related Quality of Life | Measured using the 5-level EuroQol 5-dimension (EQ-5D-5L) scales. It will be used to assess health-related quality of life in 5 dimensions, whereby each dimensions will be scored on a 5-point rating scale: no problems, slight problems, moderate problems, severe problems, and extreme problems. Scores will be combined and converted to a single index value. | Data will be collected at baseline and immediately after each step |
| Fall-Related Protective Behaviours | Measured using the revised Falls Behavioural Scale (FaB) that includes 24 statements that describe day-to-day behaviours and actions, both habitual and intentional, that if not done safely, can place an individual at undue risk of falling. Participants will respond with a four-point Likert scale. Higher score indicates safer behaviours. | Data will be collected immediately pre- and post-intervention |
| Loneliness | Measured using the revised UCLA 3-item Loneliness Scale. The score ranges from 3 to 9, with people from 3-5 as 'not lonely' and people score 6-9 as 'lonely'. | Data will be collected at baseline and immediately after each step |
| Falls-Related Healthcare Utilization Cost | Measured using the Client Service Receipt Inventory (CSRI) | Data will be collected at baseline and immediately after each step |
| Productivity Loss | Measured using the Work Productivity and Activity Impairment Questionnaire-General Health (WPAI-GH) | Data will be collected at baseline and immediately after each step |
