Description of intervention(s) / exposure
The LiFE program is a structured approach to improving the balance and strength of people at high risk of falls. The program is designed in such a way that participants incorporate the 8 balance and 7 strength activities into their daily lives and routines to gradually form habits (Clemson, Munro, Fiatarone Singh 2013). Lally and Gardner (2011) argue that habit formation is largely dependent on repetitive behavior being conducted in a consistent environment. Participants of the LiFE program are taught these activities within their own home thus maintaining the consistency of the environment (Clemson et al 2012; Lally and Gardner 2011). Additionally daily routines provide the ‘cue’ that participants need to promote the performance of the activity (Lally and Gardner 2011).
The balance activities are the tandem stand, tandem walking, one-leg stand, leaning from side-to-side, leaning forwards and backwards, stepping over objects, stepping over objects sideways and stepping in different directions. The strength activities aim to increase the load on the legs and include; bending knees, sit to stand, standing on toes and heels, walking up stairs, walking sideways and tightening muscles (Clemson, Munro, Fiatarone Singh 2013). These activities will be taught by Orientation and Mobility Instructors employed by Guide Dogs NSW/ACT. These instructors are familiar in working with the vision impaired population and will thus appropriately tailor these activities to the needs of the participants. The LIFE program will be conducted over 5 home visits (with one each week) as well as 2 booster visits and 2 phone calls (one each fortnight as the participant becomes more familiar with the program) over the course of 3 months. It is expected that each of the 5 home visits will be conducted over an hour, whereas the booster visits and phone calls should not take longer than half an hour.
Overall the duration of the program is 3 months. However there will also be a follow up assessment at the end of the 3 month period and at 12 months from the baseline assessment, to measure any improvements to the participants’ balance and strength abilities. Thus the total duration of the study is 12 months.

Outcomes
Primary outcome [1] 290653 0
Semi-structured interviews will be conducted pre and post the intervention. In the pre-intervention interviews a range of questions will be asked to gain behavioural, normative and control beliefs in regards to the participant’s view of undertaking the LiFE program. These questions have been adapted from Yardley et al which utilises the Theory of Planned Behaviour to analyse the participants’ views.
Questions to elicit behavioural beliefs
*Do you have any ideas about doing the LiFE program? Have you previously done anything similar? How do you feel about doing this program?

Questions to elicit normative beliefs
*What do you know about the LiFE program from what you have been told? Does this affect how you feel about doing the LiFE program? How do your friends and family feel about the LiFE program? Do their opinions of the LiFE program affect your views on it?

Questions to elicit control beliefs
*How easy do you think it will be to fit the LiFE program into your daily life? Can you think of any problems with do the LiFE program? What things do you think might help you do the LiFE program?

The Post-intervention questions have been adapted from the Attitude to Falls-Related Intervention Scale (AFRIS) which allow the participants to evaluate their experience in undertaking the LiFE program.
*How do you think the LiFE program was good for you?
*How do you feel your balance and strength has changed?
*Were there any unexpected outcomes from doing the LiFE program?
*What is the main thing you learned from the lessons?
*How has this impacted on your everyday activities?
*Describe how you found doing the LiFE program? easy/hard?, enjoyable?
*Do you find that your mobility has changed since completing the LiFE program?
*How do you feel about continuing to do the LiFE program? Are there any things preventing you?
*Would you recommend the LiFE to others like yourself?

The pre intervention interviews will be conducted prior to the first home visit and the post intervention interviews will be conducted at the 3 month stage after the implementation of the program.
Primary outcome [2] 290654 0
The purpose of Short Physical Performance Battery is used as a measure of the participant's balance and strength capabilities. It has three main components to be measured. The first involves measuring the participant’s standing balance in 4 stances, depending on their level of ability. These stances range from; feet together, feet apart (with and without physical assistance), semi-tandem, tandem, and single leg. The participant is required to hold their feet in each position for 10 seconds. They are allowed to use their arms, bend their knees or move their body in order to maintain their balance.

The second component requires the participant to go from sitting (on a chair with a height of 45cm) to a standing position 5 times without using their arms. The participant is required to complete this assessment in the shortest amount of time and it will be recorded by the instructor. Note: if the participant is also allowed physical assistance or to use their hands if they are otherwise unable and this will be noted on the recording form.

The final component is a timed 4 metre walk. The participant is required to walk as quickly and as safely as they can for 4 metres. The time and the number of steps will be recorded. The participant is also able to use physical assistance or walking aids if necessary.

For all of these measures, the instructor will be within reach of the participant to guide the participant and if their assistance is necessary.

The outcome assessments will be conducted at 3 points over the course of the pilot study; at baseline, at the 3 month interval and at 12 months from the baseline assessment.
Primary outcome [3] 290655 0
The Late Life Function and Disability Instrument (LLFDI) is used to assess the limitations people face in performing daily tasks and engaging in the community, which ultimately aims to provide an indication of one’s mobility (Sayers et al 2004). The first questionnaire in the LLFDI is used to measure the difficulty people face when performing the 32 stated tasks which range from unscrewing a lid to walking up a flight of stairs, thus measuring the participant’s function. This component measures upper extremity, lower extremity and advanced lower extremity abilities (LaPier 2012). The second questionnaire of the LLFDI is divided into two parts and measure a person’s disability by measuring the participant’s capability and frequency of performing the 16 tasks. These tasks range from ability to prepare meals to their involvement in social activities.
The Short Falls Efficacy Scale is a measure of how concerned the participants are about the possibility of falling when undertaking 7 different activities. These activities include; getting dressed/undressed, taking a bath or shower, getting in or out of a chair, going up or down stairs, reaching for something above their head, walking up or down a slope and going to a social event.

Statistical methods / analysis
Simple paired comparisons to compare questionnaire and short physical performance battery data; thematic analysis for qualitative data.

The sample size is 10-20 participants. This will be sufficient to investigate the acceptability and feasibility of the program through qualitative methods. The study is not powered to measure a difference in performance on the physical measures and Late Life Function and Disability instrument, but will give an indication of a likely effect size which can be assessed in a larger trial.
