Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The lower limb group will receive a home-based exercise program for the lower limb. This program is based on the Otago Exercise Program, which has been found to reduce rates of falls and injurious falls. The lower limb exercise program includes balance and strength exercises for example sit to stand, semi squats from a standing position, calf raises, toe raises, sideways walking, backwards walking and one leg stand.

The exercise instruction will be delivered by an experienced physiotherapist in three group workshops (approximately one hour each). Exercise instruction workshops will occur at weeks 1, 4 and 12. Participants will be encouraged to perform the set of exercises three times per week at home for a period of 12 months. The set of exercises should take 20-30 minutes to complete. The weight to be used at the beginning of the program and progression of exercise intensity will be individualised and determined by the physiotherapists. The exercises are to be completed with good technique and control. Once exercises can be performed comfortably, they are progressed by increasing weight and/or decreasing the support.

Participants will be provided with an ankle weight and a home exercise manual which contains clear pictures and descriptions of the exercises, and booklet about preventing falls. Participants will also be provided with a calendar to record their exercises and falls on a monthly basis. Participants will be asked to return their calendars to the research team at the end of each month in the supplied reply paid envelopes. Participants will receive a 5-10 minute booster phone call, by a member of the research team, at nine months after participation commencement.

Comparator / control treatment
The upper limb group will receive an exercise program designed to improve upper limb function. The exercise instruction will be delivered by an experienced physiotherapist in three group workshops (approximately one hour each). Exercise instruction workshops will occur at weeks 1, 4 and 12. Participants will be taught exercises such as shoulder raises, shoulder rotation, elbow flexion and extension, and rowing exercises.

Participants will be encouraged to perform the set of exercises three times per week at home for a period of 12 months. The set of exercises should take 20-30 minutes to complete. The weight of the equipment to be used at the beginning of the program and progression of exercise intensity will be individualised and determined by the physiotherapists. The exercises are to be done with optimal scapula positioning and control. Exercises are progressed by increasing complexity (eg increased range, increased load, less support), that is, maintaining form as load and range is increased and support is decreased. This program has been developed by Investigators Associate Professor Karen Ginn and Dr Paul van den Dolder who are experts on shoulder anatomy and rehabilitation, and the research team.

Participants will be provided with weights, a theraband and a home exercise manual which contains clear pictures and descriptions of the exercises. Participants will also be provided with a calendar to record their exercises and falls on a monthly basis. Participants will be asked to return their calendars to the research team at the end of each month in the supplied reply paid envelopes. Participants will receive a 5-10 minute booster phone call, by a member of the research team, at nine months after participation commencement.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The project officer will screen for inclusion/exclusion criteria. Informed consent and medical clearance will be collected. Once there are enough people for a group, the baseline assessments and questionnaires will be completed. The person will then be randomised (the group allocation will be obtained through the REDCap database) into the lower limb exercise group or into the upper limb exercises group.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomly ordered blocks, organised by investigator not involved in the recruitment and uploaded to REDCap.

Efficacy
Statistical methods / analysis
Linear regression models will be used to assess the effect of group allocation on the continuously-scored primary (DASH questionnaire) and secondary outcome measures (strength, balance, physical activity, quality of life, fear of falling, upper limb pain and function, shoulder internal and external rotation force and range of movement, health and community service use), after adjusting for baseline scores. The number of falls per person-year will be analysed using negative binomial regression models to estimate the between-group difference in fall rates after one year (primary outcome).Modified Poisson regression models will be used to compare groups on dichotomous outcome measures (proportion of fallers, proportion meeting physical activity guidelines).

The required sample size of 576 will provide 80% power to detect as significant, at the 5% level, a 30% lower rate of falls for intervention group participants than control participants (i.e., IRR = 0.70). Sample size calculations used the gennbreg command in Stata 13 and coefficients from previous studies: alpha (a measure of over-dispersion in the negative binomial regression model) was assumed to be 0.8 based on a previous RCT in a similar population (Clemson et al, 2004). We assumed the control group rate of falls to be 0.85 falls/person year over the 12- month follow-up, which is comparable with the fall rates found in similar trials with community based samples (Sherrington et al, 2008). The 0.70 value for IRR was chosen as this is comparable to the size of the effect on the rate of falls from other exercise interventions (Sherrington et al, 2008). This sample size will also be sufficient to detect a 30% reduction in the proportion of fallers (control proportion of fallers 40%, intervention group proportion of fallers 28%) with 80% power and 15% loss to follow-up.

576 participants will also be sufficient to detect a 10% between-group difference in secondary physical outcomes such as Short Physical Performance Battery (power= 90%, p= 0.05, SD=0.69, control group mean score score=0.178).
