Random allocation was 50\u2009:\u200950.<\/jats:p>\n <\/jats:sec>\n \n Interventions<\/jats:title>\n All participants received routine care; the usual-care group received an information digital versatile disc (DVD) and a single advice session at trial completion. The intervention group had an individually tailored, progressive, home-based fall avoidance strategy training programme with balance and strengthening exercises: PDSAFE.<\/jats:p>\n <\/jats:sec>\n \n Main outcome measures<\/jats:title>\n The primary outcome was the risk of repeat falling, collected by self-report monthly diaries between 0 and 6 months after randomisation. Secondary outcomes included near-falls, falls efficacy, freezing of gait (FoG), health-related quality of life, and measurements taken using the Mini-Balance Evaluation Systems Test (Mini-BESTest), the Chair Stand Test (CST), the Geriatric Depression Scale, the Physical Activity Scale for the Elderly and the Parkinson\u2019s Disease Questionnaire.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n PDSAFE is the largest RCT of falls management among people with Parkinson\u2019s disease: 541 patients were screened for eligibility. The average age was 72 years, and 266 out of 474 (56%) participants were men. Of the 474 randomised participants, 238 were randomised to the intervention group and 236 were randomised to the control group. No difference in repeat falling within 6 months of randomisation was found [PDSAFE group to control group odds ratio (OR) 1.21, 95% confidence interval (CI) 0.74 to 1.98; p<\/jats:italic>\u2009=\u20090.447]. An analysis of secondary outcomes demonstrated better balance (Mini-BESTest: mean difference 0.95, 95% CI 0.24 to 1.67; p<\/jats:italic>\u2009=\u20090.009), functional strength (CST: p<\/jats:italic>\u2009=\u20090.041) and falls efficacy (Falls Efficacy Scale \u2013 International: mean difference 1.6, 95% CI \u20133.0 to \u20130.19; p<\/jats:italic>\u2009=\u20090.026) with near-falling significantly reduced with PDSAFE (OR 0.67, 95% CI 0.53 to 0.86; p<\/jats:italic>\u2009=\u20090.001) at 6 months. Prespecified subgroup analysis (i.e. disease severity and FoG) revealed a PDSAFE differing effect; the intervention may be of benefit for people with moderate disease but may increase falling for those in the more severe category, especially those with FoG.<\/jats:p>\n <\/jats:sec>\n \n Limitations<\/jats:title>\n All participants were assessed at primary outcome; only 73% were assessed at 12 months owing to restricted funding.<\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n PDSAFE was not effective in reducing repeat falling across the range of people with Parkinson\u2019s disease in the trial. Secondary analysis demonstrated that other functional tasks and self-efficacy improved and demonstrated differential patterns of intervention impact in accordance with disease severity and FoG, which supports previous secondary research findings and merits further primary evaluation.<\/jats:p>\n <\/jats:sec>\n \n Future work<\/jats:title>\n Further trials of falls prevention on targeted groups of people with Parkinson\u2019s disease are recommended.<\/jats:p>\n <\/jats:sec>\n \n Trial registration<\/jats:title>\n Current Controlled Trials ISRCTN48152791.<\/jats:p>\n <\/jats:sec>\n \n Funding<\/jats:title>\n This project was funded by the National Institute for Health Research (NIHR) Health Technology Assessment programme and will be published in full in Health Technology Assessment<\/jats:italic>; Vol. 23, No. 36.
