Description of intervention(s) / exposure
Six month physical activity program -
An individualised home based strength, balance and walking programme (based on the Otago programme) for care recipient/carer dyads (that they can do together). It will be prescribed by the intervention physiotherapist for both the carer and the care recipient during a home visit within two weeks of baseline assessment. Although the functional levels are likely to vary, the intervention physiotherapist will aim to select several common exercises for the carer and care recipient with variation in elements to modify the specific difficulty of the exercise to the individual. In this way the carer/care recipient dyad will be able to have some common elements to share as they exercise together. Each participant will receive 4-8 exercises, to be performed at least five days each week at home (average duration around 20 minutes), and a walking program (where possible, the carer and care recipient will walk together). The intervention physiotherapist will perform a further four home visits over the 6-month duration of the exercise program, to review exercises, change exercises if indicated, and to encourage and support ongoing participation and adherence to the program.

Comparator / control treatment
Six month social visits -
To ensure an equivalent level of contact to the intervention group, participants in the social visit control group will receive an initial home visit and four further home visits from a RA. The topics of conversation will be structured and standardised.

A third arm will also be included. The usual care control group will receive an initial phone call to explain group allocation and data collection. Usual care is defined as as would normally accur if participiant was not involved in the research study.

Whether the intervention is cost effective by a health economic evaluation. It will considers the efficiency of the intervention in reducing the proportion of carers who are depressed (GDS > 5) at the final follow-up assessment compared to the control conditions. Direct health costs (using Medicare and Pharmaceutical Benefits Scheme databases, patient log and interview at assessment points), costs of providing the intervention, non-health costs , and indirect costs (eg productivity losses incurred by care-givers having to take time off other work in order to care for participant will be considered from the societal perspective.

Summary
Brief summary
Most older people with disabilities live in the community with support from informal carers. Whilst carers are generally willing to take on the caring role, it often has an adverse impact on their physical and emotional health, particularly depression. There is evidence that the lower the care recipient’s function, the more their carer experiences these problems. Whilst the effectiveness of exercise interventions for older individuals has been demonstrated, to our knowledge this is the first RCT that targets both the care recipient and the carer. This study will address the question of whether an individualised physical activity program for care recipient/carer dyads (that they can do together) can improve both the physical and psychological wellbeing of the care recipient and their carer. It will also examine whether the intervention is cost effective.
