Clinical Trial Summary

The goal of this feasibility randomized controlled trial is to assess the feasibility and compare the changes in bone mineral density before and after the intervention in post-stroke older adults. The main question[s] it aims to answer are:

• What are the baseline sociodemographic and bone health characteristics of post-stroke older adults in this study?

• Is it feasible to undertake a larger RCT to assess the effectiveness and implementation of BOUNCE program?

• Is there a difference in bone loss between groups?

• Is there a difference in bone turnover markers at baseline and at six months?

• Is there a difference in the incidence of falls and fragility fractures between groups?

• How receptive are post-stroke patients/carers to the use of food/exercise diary?

• What are the perceived motivators and barriers to implementation of BOUNCE program within real clinical settings among healthcare professionals, participants and carers?

• What is the experience of healthcare professionals, participants and carers undergoing BOUNCE program?

Participants will be divided into two groups:

1. Standard care

2. Intervention group (BOUNCE Program) Researchers will compare both groups to see any changes in the bone mineral density and bone turnover markers before and after the intervention.

Description:

Stroke causes secondary osteoporosis, falls and fractures. The 2020 Malaysian Stroke Guideline recommends fall and fracture risk assessment in all older stroke patients, but it does not make a firm recommendation on the interventions to address post-stroke bone loss. Stroke increased the risk of fall by 1.5 times compared to the normal population and quadrupled the risk of fracture. Hip fractures will increase the cost for treatment, hospitalization, operation and complicate the rehabilitation process from the stroke itself.

Hence, our study aims to develop and assess the feasibility of a multi-domain intervention (BOUNCE program) for bone health among older adults with acute stroke. A multi-domain non-pharmacological intervention is proposed due to the complex nature of bone loss in older post-stroke patients such as low serum Vitamin D, sarcopenia, frailty, comorbidity, ageing and hemiparesis. Therefore, this study is designed through the 2021 MRC Framework of Developing and Evaluating Complex Intervention and is divided into 3 phases. The first phase is a systematic review to identify evidence on non-pharmacological interventions for post-stroke bone health. Phase 2 is the development and validation of a novel multi-domain intervention protocol for BOUNCE program through an expert consensus development conference. The final phase will be a feasibility trial of BOUNCE program, which is further divided into two components. The first component is a randomized, controlled, single-blinded feasibility trial (RCT) of 6-months intervention (BOUNCE program) versus standard care, which primarily assesses bone loss through bone mineral density and bone turnover markers. The second component is a qualitative analysis through Focused Group Discussions on the feasibility of BOUNCE program among healthcare professionals, patients and carers. The outcome of this study will inform the next step of evaluation, which is a future full RCT to assess the effectiveness and economic studies before it can be implemented widely.
