Reference	Study design	Study purpose	Intervention	Sample size; % female; age (years) (SD); drop out	MMSE score (SD) or rating of dementia	Number of falls	Intervention effect	Follow up
Mackintosh and Sheppard43 Australia	Single-group pre and post test	To assess the feasibility and effectiveness of preventing falls for older people with dementia from an Italian background, living in the community	HLDR program, individualized falls and injury management plan given to each participant, including strength, balance and mobility exercises, foot health, medication management, vision assessment, footwear issues, walking aids. They attended HLDR once a week for 6 months	64 completed pretest; 32.8% (21/64) female; 79.6 (7.4) years; 32 completed post-test	MMSE score 13.0 (7.4)	17 participants had fallen in the 12 months prior, and 12 participants fell in the 6-month study period	No significant differences between baseline and post-test for number of fallers, balance, cognitive function (MMSE) or aerobic capacity. 17 people at baseline were classed as fallers (previous 12 months) but only 12 people (38%) had falls over the 6-month study period	6 months
Pitkälä et al41 Finland	Randomized controlled trial	To investigate the effects of intense and long term exercise on physical functioning and mobility of people with Alzheimer’s Disease living in the community	Three-arm trial: 1) group-based exercise (GE: 4 hour visits, twice a week with approx. 1 hour training each session); 2) tailored home-based exercise (HE: 1 hour training), both twice a week for a year; and 3) a control group (CG) receiving usual community care	210 participants randomized into three equal groups; 61.4% average female; 78.03 (5.3) years; 49 participants dropped out prior to 12-month follow-up (23.3%)	MMSE score 18 (6.3); 67.1% suffered moderate or severe AD according to the Clinical Dementia Rating (CDR), and 96% were receiving AD medication	No baseline falls data provided. At 12 months there were 355 falls in total	HE and GE had significantly fewer falls over the 12 months; all groups deteriorated in functioning; CG deterioration was significantly faster than the HE or GE groups at 6 and 12 months	3, 6, and 12 months
Suttanon et al38 Australia	Randomized controlled trial	To evaluate the feasibility and safety of a home-based exercise program for people with AD, and provide initial evidence of intervention effectiveness in improving balance and mobility and reducing falls risk	Individualized home-based exercise program supervised by a physiotherapist. Balance and strength home exercise group versus education/support (controls). Included exercises and a graduated walking program based on the Otago exercise program, participants completed exercises 5 times a week. Both intervention and control group had six home visits and five phone calls over the 6-month study	40 participants: 19 to exercise group and 21 to control (education) group; 62.5% female; 81.9 (5.72) years. 11/19 exercise group completed post testing, three of the control group did not complete follow-up	MMSE score 21.28 (4.58); Intervention group: 20.89 (4.74), control group: 21.67 (4.43)	Falls rate of exercise group declined by 33% for the 6-month intervention, control group increased by ~89%. Similar pattern for proportion of fallers, though neither of these between-group changes was significantly different	Significant improvement by the intervention group compared to the control group for functional reach, and the Falls Risk for Older People – Community version. Trends towards improvement in the exercise group for step test, modified Clinical Test of Sensory Interaction of Balance and the Timed Up and Go test	6 months
Wesson et al42 Australia	Randomized controlled trial	To explore the design and feasibility of a novel approach to fall prevention for people with mild dementia living in the community	Strength and balance training exercises and home hazard reduction. Six occupational therapy home visits (and three phone calls), five home visits from a physiotherapist. The physio-prescribed and progressed the exercises. Exercise intervention consisted of a maximum of six exercises from the WEBB program, including sit to stand, calf raises, step ups onto a block, stands with diminishing base of support (eyes open or closed), step-overs, foot taps onto block, lateral side steps and sideways walking. Participants were asked to complete the exercises three times per week. Control group received usual care	22 participants randomized into two equal groups; 40.95% female; 79.8 (4.6) years; all controls and ten of the intervention group completed follow-up	MMSE score: 23.5 (3.7)	Falls during previous 12 months: 16 falls in total. Intervention group had fewer falls (n=5) than the control group (n=11) during the intervention	Risk of falling and number of falls was lower in the intervention group; however neither was significant. No significant differences in physiological outcome measures between groups due to small sample size and incomplete data primarily in the intervention group at follow-up	3 months (12 weeks)
