Description of intervention(s) / exposure
The intervention group will undertake a 6 week supervised step training session consisting of warm-up exercises, reactive step training (with an added cognitive component) and volitional step training, once a week lasting 45 minutes each session. Within this 6 week training period, they will also complete a home-based lower limb strength training twice per week, lasting 15 minutes each session. The step training will be supervised by (an exercise physiologist) and the intensity will be tailored according to individual capacity. Reactive step training will involve learning rapid and elevated reactive stepping using a manual tether-release technique. A 7-14cm height foam block will be used to train elevated and rapid stepping responses. The cognitive component of it involves the participant memorising and reciting words in order. The volitional step training will involve stepping on to a slippery plastic sheet with progressively lengthened slip targets. An attendance checklist will be used to monitor attendance to training sessions.
The home-based lower limb strength training will be conducted at home (twice/week). It involves the warm-up of quad stretch, hamstring stretch and hip flexor stretch (1 set of 20 seconds), and the exercises high knee with resistance band, standing hip abductions with resistance band, standing glute kickbacks with resistance band, and squats with resistance band (1 set of 20 repetitions). Participants will receive a link to a home exercise video (exercise demonstrations for their training program). Exercise diaries and weekly SMS survey will be used to monitor adherence to training program.

Statistical methods / analysis
Participant characteristics will be compared between the intervention and control groups using the independent-sample t test. The physical and cognitive measurements at post-intervention will be compared between the groups using the analysis of covariance (ANCOVA) while adjusting for any baseline differences (e.g. age, falls risk). Poisson regression with number of falls as a dependent variable, group allocation as an independent variable will be used to compare the rate of falls between the groups. P < 0.05 is considered statistically significant.

Summary
Brief summary
Decline in cognition and physical function often occurs simultaneously and increase falls risk in older people. Previous research has shown that step training reduces falls risk as well as improving cognition. Previous research has also shown that combining motor and cognitive training would induce greater cognitive improvements than individual motor or cognitive training. Therefore, we have created ReacStep, a novel step training program with an added cognitive component. it requires minimal equipment and can be individually tailored to older adults with a range of physical functional levels. This trial will examine the effects of the ReacStep program on fall risk and cognitive function in older adults. We hypothesise the the ReacStep program will improve fall risk and cognition in healthy older adults. If this study is successful at improving fall risk and cognition, it will provide a basis for a larger clinical trial and a feasible solution for preventing falls and dementia in older adults, and can be a new training program that health professionals can use in their practice.
