Description of intervention(s) / exposure
"Staying UpRight" is a strength, power and balance program, delivered in 1 hour sessions, twice weekly over 1 year. It is a group program (approximately 8 residents per group), delivered by one physiotherapist and one assistant.
Strength training uses low repetitions, moderate-high resistance (2 x 10 repetitions at 5-7/10 effort) in weight-bearing positions (e.g. lunges, squats, sit to stand, heel raises) progressed by increasing the speed and/or depth of the movement (e.g. deeper lunges). Balance training comprises static and dynamic activities (e.g. tandem and one legged stand, reaching, stepping, walking, and turning) and is progressed by reducing hand support, reducing the base of support, reducing visual input; and adding a cognitive task. For example, walking on the spot on toes and heels is progressed to walking on toes and heels forwards, backwards and sideways; and stepping over obstacles.
The program is manualised and includes instruction on exercise delivery and exercise progression. Exercises completed in each session, and exercise progressions for the group are recorded on a spreadsheet, in addition to a participant attendance record.
The active control program, led by an activities coordinator, uses only seated activities (no standing component), ‘light’ work (<5/10) with no resistance exercises and no progressions. Activities focus on seated movement and variety e.g. seated upper and lower limb activities; seated boxing, seated marching, heel and toe tapping; seated upper and lower limb stretches using non elastic bands and games e.g. seated scarf catch and throw, pass the parcel.

Fidelity of program delivery will be checked during the first 6 months (of physiotherapist delivery) and the second 6 months (of facility staff member delivery) through:
a. A site visit from the project manager within the first 2 months of each 6-month block, which entails observation of a class taking place. Feedback is given as necessary to the physiotherapist or facility staff member to ensure fidelity of intervention delivery. Any actions expected in response to the feedback will be monitored via telephone calls and visits as required.
b. A monthly audit of the spreadsheets used to record each participant’s exercises by the physiotherapist research team member (who initially trained the research physiotherapists to check the class content). If violations in the exercise program are noted, the physiotherapist research team member will contact the delivering physiotherapist or facility staff member and discuss the issues to a satisfactory resolution.
c. All observed or noted episodes of program fidelity violations will be recorded and reviewed monthly by the research physiotherapy team members.

Comparator / control treatment
Participants in the comparator arm of the trial will receive a supervised group exercise program (approx. 8 residents per group). The “Flex and Stretch” activity program comprises only seated activities, stretches and movements at low intensity (< 5/10 effort) with no resistance component. The program is dose-matched to the intervention and delivered for 1 hour twice a week for 1 year.
An activities coordinator trained in the program will deliver the program for the first 6 months. In the fifth month, a volunteer will engage, learn the program and take over delivery for the second 6 months. Support for the volunteer from the physiotherapy research team member will remain available over the second 6 months. The programme is manualised and includes instruction on exercise delivery. An attendance record for all participants will be kept throughout the trial.

The fidelity of the comparator programme will be checked during the first 6 months (of research assistant delivery) and the second 6 months (of volunteer delivery) by a site visit from the project manager within the first 2months of each 6- month block, which entails observation of a class taking place. Feedback will be provided to the research assistant or volunteer to ensure fidelity of intervention delivery.
Controlling contamination between intervention and comparator groups within a single care-home facility will be managed by separating the delivery of the class from non-enrolled residents, using non-public areas for the classes, and using different facilitators for the different classes.

Statistical methods / analysis
The sample size is estimated on the primary outcome, falls rate. To detect a 25% reduction in falls, assuming a control rate of 2.6 falls per resident per year (based on pilot data), we estimate a required sample size of 264 in each group (528 total; two-tailed test, (a=0.05, power= 90%). The anticipated drop-out rate is 35%, which will be replaced by recruitment at participating facilities throughout the trial. Final recruitment in each facility will stop 12 weeks prior to completion of the 12 month intervention at each facility.

The anticipated drop-out rate is 35%, which will be replaced by recruitment at participating facilities throughout the trial.
Data analysis
1. Total number of falls, number of fallers, people sustaining a fall-related fracture or brain injury; rate of falls (falls per person year); multiple fallers and number in each analysis will be reported.
2. Prior fall-incidence rates, calculated as number of falls/ resident/ year using the audited six months prior to enrolment. Negative binomial regression models will be fitted to determine the Incident Rate Ratio (IRR) between groups. Logistic regression methods will be used for risk of falls, and linear regression for fall free activity. All models will control for prior falls rate, level of dependency, cognition (Montreal Cognitive Assessment [MoCA]) and functional status (interRAI™ clinical assessment data; Short Performance Physical Battery; Timed Up and Go).
3. Falls rate per minutes of ambulatory activity will be calculated. Associations between ambulatory activity volumes and patterns (bout length), spatiotemporal gait parameters, falls rate, cognitive status and functional status will be explored using bivariate and regression analysis. Cox regression will identify predictors of activity-adjusted falls risk. Change in ambulation volumes and patterns (bout length) and spatiotemporal gait parameters will be reported for the intervention group using comparator group data as reference
4. Analysis of ambulatory activity (derived from accelerometer data) will include (i) summary measures (volume, pattern and variability of walking bout duration) and (ii) discreet gait characteristics (mean and variability of gait velocity, step length, step time, step symmetry). Comparison of change over time in gait variability between the intervention and comparator groups will be undertaken using regression techniques.
5. Gait parameters will be examined as a function of cognitive level and specifically each of the 14 spatio-temporal features including gait speed and gait variability will be mapped against cognitive function and functional status. Range of gait parameters will be described and compared between those with normal cognition, mild, moderate and severe cognitive decline using regression techniques examining amount of activity as a moderator of change. Change over time will be examined; natural history of gait change will be estimated from the active intervention (“flex and stretch”) group data.
6. Cost effectiveness. Unit costs will be assigned using WIESNZ weights, indicative DHB costs for outpatients, and literature/expert judgement for anything not already covered. Incremental cost effectiveness for intervention versus comparator activity will be assessed (i) per fall prevented and (ii) per injury fall (resulting in hospitalisation) prevented. The cost-effectiveness of Staying UpRight as an adjunct to usual activity will be explored for these same outcomes by removing the costs of the comparator activity (retaining any effect). Sensitivity analyses will be performed for all analyses to indicate the uncertainty in our estimation of the costs and consequences using bootstrapping. Decision uncertainty will be assessed using a probabilistic sensitivity analysis using standard diagrams (CEACS/CEAFs) and varying assumptions around care home size.
