Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
The primary aim of the project and its consortium partners is to evaluate innovative home-based technologies for continuous monitoring and prevention of falls in community-dwelling older adults. This approach will enable tailoring individualised prevention programs coached by iStoppFalls, including exercise and education. Various different home-based technologies are employed:
1. The PC/ Microsoft Kinect 'Registered Trademark' based fall preventive exercise game (exergame ) facilitates real preventive exercise training, where data is acquired by unobtrusive sensing by PC/ Microsoft Kinect 'Registered Trademark'.
2. The Knowledge Based System (KBS) enables secure data management.
3. The iTV application utilized the Microsoft Kinect 'Registered Trademark' device. It provides all the relevant KBS data (personal health advisor), and thus provides the necessary information to include fall-related education and other exercise-related components.
4. The Philips Senior Mobility Monitor (SMM) unobtrusively and regularly monitors mobility in daily life.
The 16-week exercise intervention primarily targets balance and strength properties and is suited to the functional level and interests of older people. The content of the iStoppFalls fall prevention exercise program was based on evidence-based fall prevention interventions targeting muscle strength and functional balance and mobility in older adults. The exercises selected for the prevention program were adapted to be incorporated into a videogame setting. The strength exercises were adapted into a videogame-based training program and the balance exercises into balance games. To maintain the challenge of the games to maximise improvements in ability and skill level, the level of difficulty is gradually increased within each game.

Sixty community-dwelling older people will be advised to complete a minimum of 3 sessions per week (30 to 60 minutes/session), adding up to at least 120 minutes of system use per week. The intervention will be unsupervised and participants will exercise in their own homes. Instructions will be provided at the beginning of the study period when the system is installed. To encourage adherence, participants will be contacted by phone after weeks 1, 4, 8, 12 or if data upload shows non-adherence in between (non-use of the system for 5 days). In addition participants will be provided with a phone number to call if they have questions or problems related to system.

Comparator / control treatment
The control group will receive no intervention, but an information brochure about common fall risk factors.
Participants in the control group will be provided with and education booklet about different fall risk factors (i.e., vision impairment, medication use, foot pain, vitamin D insufficiency) at the beginning of the trial and asked to maintain their usual activities. Participants will be provided with a phone number which they can call if they have questions or problems related to content of the educational material.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Potential participants will be recruited at retirement villages through oral presentations, flyers, posters, and advertisements.
After a potential participant fulfills all eligibility criteria, concealed allocation will be performed via central randomization.
Investigators will be blinded to whether a participant is in the intervention or control group.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Central randomisation by computer will be used. The central randomisation office is remote from participant recruitment sites. The person performing the randomisation will not be involved in any assessments of this study. Screening for eligibility and pre-assessment will be undertaken before randomisation.
Random allocation (allocation ratio 1:1) into one of the 2 groups (intervention/control) will be performed.
Couples (participants living in the same household) will be randomized into their own blocks.

Statistical methods / analysis
between-group:

Differences at baseline will be explored using Chi square (discrete variables) and Student t-tests (continuous variables).
Between-group comparisons of continuous measures will be made using general linear models (ANCOVA) controlled for baseline performance and other confounding variables if required. Negative binomial regression will be used to test for differences in fall rates between groups.

An intention-to-treat approach will be used for all between-group analyses.

The estimated sample size of 52 participants is based on a large effect for the PPA as outcome measure (effect size f=0. 40, ANCOVA, Alpha 5%, Power 80%, Numerator df 1, Number of groups 2, Number of covariates 1). With an anticipated dropout of 15%, 60 participants will be recruited.

The Alpha level will be set to 5%.

within-group:

Paired t-tests and repeated measures ANOVA will be used to analyse changes within groups and to explore subgroups (e.g. different doses) in the intervention group.
