Trial name or title	Effectiveness of dual‐task functional power training for preventing falls in older people: Study protocol for a cluster‐randomised controlled trial
Methods	Cluster RCT
Participants	Target sample size: 280 Inclusion criteria: aged 65 years and over, at an increased risk of falling, currently resident in retirement villages, able to speak English, walk unaided or with minimal assistance (walking stick or walker) or at least 50 metres and be cognitively intact; clearance from local doctor prior to exercising if has any contraindicated medical conditions to exercise Exclusion criteria: current or prior participation in a structured progressive resistance training programme and/or organised balance training > 1 a week in the past 3 months, acute or terminal illness likely to compromise exercise participation, unstable or ongoing cardiovascular/respiratory disorders, musculoskeletal or neurological diseases disrupting voluntary movement or that might limit training, upper‐ or lower‐extremity fracture in the past 3 months, visual impairment not corrected with glasses
Interventions	1. Exercise programme involving dual‐task functional power training (DT‐FPT), 2 twice a week supervised for 6 months, 'step‐down' maintenance for 6 months, follow‐up after 6 months 2. Usual care control group
Outcomes	1. Number of falls over the 6‐, 12‐, 18‐month period; details of the fall location, cause, injury, treatment and the healthcare utilisation 2. Changes in lower‐limb functional muscle strength and power, isometric knee extensor, dorsi‐flexor and hand‐grip strength, dynamic balance and reaction time, gait, Instrumental Activities of Daily Living (IADL), quality of life, cognitive function and fall‐related self‐efficacy
Starting date	23 October 2015
