Description of intervention(s) / exposure
The relationship between executive function and perception of walking abilities will be assessed in patient's aged 60 years or over undergoing in-patient rehabilitation. The relationship between these measures and falls or hospital re-admission will be assessed after 12 months.
Executive function will be assessed by the Trail making test (conducted at baseline and after 12 months) and perception of walking abilities will be determined by the relationship between the physical timed up and go and imagined timed up and go (conducted at baseline and after 12 months).

Statistical methods / analysis
All statistical analyses will be performed using IBM SPSS (Version 22). Statistical significance is set at p < 0.05. Normality of distribution of the test measures will be confirmed using the Shapiro-Wilk test. Outcome measures will be presented as mean (standard deviation).
Pearson correlation coefficients will be used to identify relationship between TUG delta and executive function (Trail making test). A multiple linear regression model will be used to determine the independent association of TUG delta and executive function on falls over a 12-month period. Independent variables of TUG physical, cognition, grip strength and relevant demographics will be stepwise entered into the model if they increase the probability of F by at least 0.05

Summary
Brief summary
The proposed research seeks to answer the following research question:
In older adults undergoing rehabilitation for a non-neurological condition, does the perception of one’s own walking ability relate to their executive function and future falls risk?
A prospective cohort study conducted at a sub-acute rehabilitation facility will identify the relationship between perception and executive function. Perception will be assessed by determining the difference in the time to complete a mobility task (the timed-up-and Go) physically and in their imagination. Executive function will be assessed by The Trail Making test. This project will identify the relationship between real and imagined walking and executive function in 100 older adults undertaking in-patient rehabilitation. This project will also establish the relationship between imagined walking, executive function and falls. Participants will have their physical and cognitive abilities tested twice over a 12-month period. It is expected that older adults with poor accuracy of imagined walking will have poorer executive function and be more likely to fall than those with high accuracy of imagined walking. The results of this project will provide a platform for earlier cognitive and executive function testing in older adults leading to timely detection of mild cognitive impairment and dementia.
