Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants in the intervention group will undertake interactive exercise video games using the Xbox Kinect platform, selected and supervised by a study investigator. Sessions will be offered over 8 weeks for approximately 45-60 minutes, twice weekly. Exercise activities will be chosen by a physiotherapist based on the residents’ baseline physical performance measures Activities will include balance and lower limb exercise and also upper limb activities. Activities maybe progressed or varied each session, depending on the individual skill levels.
Although the video games are generally designed for play by 1-2 people, residents of similar ability may be able to join in the activity at one time. Residents may also be able to rest while others do an activity, before joining in again. The group size and precise way the exercise program will be conducted will be dependent on the spread of participants’ abilities as well as the facility’s schedule and physical environment. Participants will be reminded about each session but attendance remains voluntary.

Outcomes
Primary outcome [1] 291117 0
The De Morton Mobility Index (DEMMI). The DEMMI is a 15 item test battery measuring physical performance, completed under supervision, which includes transfers, walking and balance tasks scored on a 100-point scale.
Timepoint [1] 291117 0
Baseline and 8 weeks
Primary outcome [2] 291118 0
The Timed Up and Go (TUG). The TUG is a commonly used measure of agility, scored in seconds, which involves rising from a chair, walking 3m at usual pace, turning, walking back and sitting back down.
Timepoint [2] 291118 0
Baseline and 8 weeks
Secondary outcome [1] 306023 0
Habitual activity. Measured using a triaxial accelerometer. The duration of time spent active (in ambulation and standing) and sedentary (sitting and lying down) measured over the waking day, over a 4 day period

Baseline and 8 weeks

Eligibility
Key inclusion criteria
Older people living in rest homes who can communicate, transfer and walk independently with or without a walking aid, regardless of cognitive ability, will be eligible to participate.
Minimum age
65 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
Insufficient vision to see a television screen; and any unstable medical, orthopaedic or neurological condition that would contraindicate participation in an exercise program e.g. acute febrile illness, unstable or acute heart failure.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
A cluster randomised controlled study design will be used, with rest home facilities that consent to participate randomised to either the intervention or the control group. Residents in enrolled facilities will be invited to participate.
After completion of baseline measures of all enrolled residents , the recruitment investigator will telephone the independent investigator holding the randomisation schedule.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will be via a computerised central randomisation service. An independent investigator in a distant site will hold a computer-generated randomisation schedule.

Efficacy
Statistical methods / analysis
Sample size estimates for this study have been calculated based on the DEMMI outcome measure. Based on existing research, estimated from a baseline mean score on the DEMMI of 42 +/- 15, and an expected minimal clinically important difference of 10 (power = 0.80; 2–tailed with alpha set at 0.05), the sample size required is 72 ( 36 per group). Adjusting for the cluster design effect (cluster size 8, ICC 0.2), 82 would be required. At 20% attrition, the sample size would be 102.
