Outcomes
Primary outcome [1] 287052 0
Number of accidental falls per participant. Falls will be recorded monthly for 12 months on a diary (calendar) and be collected by mail. Participants will need to record 'F' (i.e., if a Fall) or 'N' (no fall) every day of the month. Every reported fall will be further contacted by phone to complete details about that fall (where was it, did it ended with injury, type of injury and treatment if applicable). Participants with missing diaries will be contacted by phone, fill the diary with the researcher and will be asked also to mail the diary.
In addition, the monthly diary will collect information on utilization of health services for economic evaluation using a list of codes that is printed on the calendar; a visit to GP, any use of a specialist (i.e., physiotherapists, consultation with medical specialist) , visit to an outpatient Clinic, Emergency room, use of ambulance and whether there was a change in medications reported at baseline.

Cognitive function - Trail Making Test A and B
Time to complete the Trail Making Test (TMT, part A and B) will be assessed. The TMT A and B is an executive functioning tests. Part A measures processing speed and involves participants connecting consecutive numbers (e.g., 1-2-3), and Part B is a measure of executive function of ?task shifting? and involves participants connecting alternating letters and numbers (e.g.,1-A-2-B). The difference in time between the two parts will be calculated to isolate the executive component of this test.

Physiological Profile Assessment (PPA). The PPA comprises of five tests which provide an overall falls risk score: Vision (edge contrast sensitivity), peripheral sensation (proprioception), lower extremity strength (knee extension), simple reaction time using figure press as the response, and body sway when standing on the medium-density foam rubber mat, which is a measure of balance.

Choice Stepping Reaction Time Tests without and with cognitive load. Three short tests which requires the subject to perform quick, correctly targeted steps in response to visual cues. The tests comprises of arrows appear randomly on a computer screen. The arrows have graphical presentations on a dance MAT (front left, front right, side left, side right).
Test 1: Participants are asked to step as quickly as possible onto the corresponding arrow of the mat and returned to the centre. The time to react and the time it takes to return to the centre is recorded using a customised software.
This test measures The tests measure visual attention, central processing, reaction time and movement time.
Test 2: Similar test are then performed but with a no-go task which determine by the colour of the errors (i.e., blue color to inhibit response). The time it takes to respond and step back plus the number of errors are recorded. This test also measures as above plus response inhibition.
Test 3: this test is the modification of the Stroop Color-Word to a motion. Participants are shown "congruent arrow" (i.e., the direction of the arrow and the word "front" are similar) and incongruent step by the word. Time and errors are recorded. This test measures response inhibition and selective attention which is an executive function measure.

Colour Choice Reaction Time Test - this test requires minimal locomotion but measures reaction time with response inhibition. The test involves the presentation of targets of different colours in one of four cells in a square grid. Participants respond to targets by using hand buttons or foot pedals. Blue target requires a response inhibition (i.e., not pressing any buttons). The computer recorded reaction times and errors (accuracy).

Rey Auditory Verbal Learning test (RAVLT). The test evaluates verbal learning and memory, including proactive inhibition, retroactive inhibition, retention, encoding versus retrieval, and subjective organisation. The test starts with a list of 15 words, which an examiner reads aloud at the rate of one per second. The participant's task is to repeat all the words he or she can remember, in any order. This procedure is carried out a total of five times. Then the examiner presents a second list of 15 words, allowing the participant only one attempt at recall. Immediately following this, the patient is asked to remember as many words as possible from the first list.

The Short Physical Performance Battery (SPPB) measures lower limb functional status by assessing balance, gait, strength and endurance of the lower extremities. The tests include side-by-side, semi-tandem, and tandem standing tests to complete 10 seconds, time to complete 3-meter walk at normal speed , and a timed sit-to-stand 5 repeat.

$ per fall prevented.
Costs for total health care resource utilisation, rather than only falls-related healthcare utilisation will be collected monthly for 12 months. Participants will report on the falls diaries any inpatient hospital admissions, Emergency department visits, Ambulance trips, Doctor and allied health visits, prescribed medications, Home care / nursing care,Nursing home or long term care admission. The cost for each of these item will be extrapolated from the relevant source (e.g., Medicare Benefits Scheme fee for service, PBS for medications, etc..). Participant out-of-pocket costs and care provided by family and /or friends will not be included.
The cost of the trial is itemized in the trial budget.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
All 126 retirement villages in Sydney Greater Metropolitan Area will be contacted by letter to determine eligibility and interest in participating. The first 28 eligible and interested villages to respond will be invited to participate in the trial. Invitations will be sent to all residents of the participating villages, and an information session will be held in order to recruit individual participants. Researchers will attend the retirement village and conduct a telephone screening with potential participants. Once eligibility is established, baseline measures will be collected. Once recruitment and baseline data collection at each village is complete, that village will be randomised. Randomisation will be by minimisation of two of the baseline variables (physiological performance assessment “FallScreen” and Trail Making Part B) which are associated with the primary outcome. The randomisation will be performed by the study statistician using a computer program that allocates the village with probability 0.8 to the group that minimises the imbalance of these variables between intervention and control groups. The study co-ordinator will telephone the study statistician and be advised of the village’s allocation, and will arrange for the delivery of the intervention if appropriate. Allocation will thus be concealed from the research team recruiting villages and participants, as randomisation will occur after baseline measures have been completed.
