Trial Review

Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

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

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Subjects will play an adapted open source active computer game (exergame) via their TV. A step pad and a computer unit will be provided to them.
While stepping on the step pad subjects interact with the computer. The game idea is to step as accurately as possible in terms of direction and timing. Arrows drift up the screen; when they reach a location on top of screen the subject's task is to step on the corresponding arrow of the step pad.
They will play this game to music but will not step in the rhythm to the music. In addition they will be distracted by other elements on the screen for which their task is not to step.
Participants will be asked to play as many times as they want with the recommended dose of 2-3 sessions per week for 15-20 minutes over a period of 8 weeks. The participants can play more often if they want to.
In addition subjects will be asked to do a choice stepping reaction time task once a week. In this game/test subjects step as quickly as they can in different step directions depending on arrows changing their color on the screen.
The intervention will be unsupervised. Participants will be instructed at the beginning of the study period in their homes when the system will be installed. To control for compliance people will be contacted by phone in week 1, 2, 3 and 6.

Outcomes
Primary outcome [1] 279756 0
Choice Stepping Reaction Time (CSRT) in milliseconds measured using a step pad
Timepoint [1] 279756 0
at baseline and 8-9 weeks after randomization
Secondary outcome [1] 294384 0
Physical/physiological fall-risk assessed by the Physiological Profile Assessment (PPA); this test battery involves 5 tests of different physiological functions involved in postural stability (contrast sensitivity, proprioception lower extremities, strength lower extremities, postural sway, hand reaction time). An overall score is generated from these 5 weighted sub-scores.
Timepoint [1] 294384 0
at baseline and 8-9 weeks after randomization
Secondary outcome [2] 294385 0
Fear of falling is measured by the short version of the Icon-FES, an iconographic questionnaire (10 items).
Timepoint [2] 294385 0
at baseline and 8-9 weeks after randomization
Secondary outcome [3] 294386 0
physical performance measured using the Timed up & go test (TUG), Sit to Stand 5 times (5STS), Alternate Step test (AST), 6m-walk
Timepoint [3] 294386 0
at baseline and 8-9 weeks after randomization
Secondary outcome [4] 294430 0
cognitive functions measured using pen- and paper-based neuropsychological tests as well as newly developed combined tests of stepping and cognition (Stroop test, Trailmaking Test A&B, Digit Symbol Substitution test)
Timepoint [4] 294430 0
at baseline and 8-9 weeks after randomization
Secondary outcome [5] 294492 0
physical activity measured using the Incidental and Planned Exercise Questionnaire (IPEQ)
Timepoint [5] 294492 0
at baseline and 8-9 weeks after randomization

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
A central randomisation by computer will be used. The central randomisation office is remote from participant recruitment centre and participant details will be provided by Email. The person performing the randomisation will not be involved in the clinical part of this study. Screening for eligibility and pre-assessment will be undertaken before randomisation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
We will use block-randomisation to form the allocation for the two comparison groups, using computer-generated random numbers. Couples (participants living in the same household) will be randomised into their own blocks.
Masking / blinding
Blinded (masking used)
