Changes in Spatiotemporal Gait Parameters During a Digitally Assisted Self-rehabilitation Program for Elderly Fallers ( DigiWalk )

Falls are a health issue that is both common among older adults (affecting 1 in 2 people each year after age 80) and serious due to their traumatic, psychological, and functionally disabling complications. The international literature shows that it is possible to prevent recurrent falls by addressing the risk factors for falls, particularly by combating a sedentary lifestyle and deconditioning through regular standing and mobility exercises as part of a rehabilitation program. As part of France's major national plan to prevent falls among older adults, and at a time when medicine is becoming increasingly personalized, prescribing a digitally assisted self-rehabilitation program for people over 65 following a fall could enable as many people as possible to benefit from rehabilitation that boosts their motivation and reduces the time spent by healthcare professionals, while ensuring high-quality follow-up care. LNA Santé, in collaboration with the Angers and Nantes University Hospitals, has developed a personalized, digitally assisted fall prevention program (the Stand'hop app) comprising three types of activities: tailored physical exercises, structured lifestyle advice, and an objective measurement of the patient's physical activity. Before moving forward with a larger-scale clinical trial to evaluate the effectiveness of this personalized, digitally assisted fall prevention program, the present study DigiWalk aims to describe changes in walking performance over 7 weeks among older adults who have experienced falls, when the program is used as an adjunct to standard care, compared to changes observed in older adults who have experienced falls and receive only standard care.

The Geriatric Emergency Department Pharmacologic Harm Prevention Project

The goal of this project is to determine whether pharmacogenomic testing (using participants' DNA) can help optimize medication prescribing and reduce side effects in older adults taking five or more medications. The main questions it aims to answer are: * Can DNA-based prescribing reduce medication-related side effects, especially falls and fall-related injuries? * Does providing pharmacogenomic results to primary care physicians improve medication safety compared with usual care? Researchers will compare two groups: 1. DNA Care Pathway: Physicians receive patients' DNA results to guide prescribing. 2. Emergency Department Care Pathway: Physicians provide usual care; DNA results are shared only after study completion. Participants will: * Provide a cheek swab sample for DNA analysis (1 minute). * Receive monthly follow-up phone calls for 6 months to track falls, injuries, medication changes, and side effects. * Complete a fall and medication calendar. * Allow researchers to review primary care physician medical records for study outcomes. Approximately 1,000 participants will take part, with follow-up lasting about 6-7 months.
