New Clinical Rehabilitation Approach for the Management of Falls Risks

This research program on aging to create Living Lab Sag aims at maintaining older adult's full individual and collective abilities in the Saguenay-Lac-Saint-Jean (SLSJ) region. The need for innovation and creativity aims at optimizing independence, whether for mobility, the ability to take charge of one's health, to remain at home, to have access to services, and to prevent falls in a frail and aging population. Thus, this program includes expert investigators in the areas of health, engineering and computer science, aging, neuropsychology, geriatrics, and rehabilitation/prevention within a multidisciplinary work approach for durable health for older adults in Saguenay. Living Lab Sag will be implemented based on an enriched research program, approved by the CIUSSS SLSJ (CER# 2019-008) and entitled: Development of a new clinical approach in rehabilitation for the care of older adults with a neuro-musculo-skeletal disorder and a risk of falling: Project in partnership between UQAC and the specialized geriatrics services of the CIUSSS-SLSJ. Canada census reports clearly show the demographic aging of the local population. It is predicted that people 65 years and older will comprise about 24% of the population in 2036, in Canada and Quebec. In parallel with this demographic phenomenon, 50% of Canadians live with at least one chronic disability that is often associated with advanced age, as well as with different neurological, orthopedic and cardiopulmonary degenerative diseases. Some diseases affecting the neuro-musculo-skeletal system will lead to physical disability and to a significant functional limitation in terms of balance, mobility and walking and, consequently, to an increase in the risk of falling. Falls have a significant financial effect on healthcare services. Every year, in Quebec, approximately 1/3 of people aged 65 and over will fall and, sadly, some data suggest that 424,000 people will die, worldwide, because of a fall. The present scenario also shows the importance of developing strategies to reduce the weight of falls on the healthcare system, such as the creation of Living Lab Sag where the older adults will be at the heart of the situation. With team's experience in the area, one strategy among others is the early identification of physical-functional factors leading to a fall, despite the presence of other associated extrinsic factors that are also associated with the fall (i.e., multifactor phenomenon). This identification can be realized through neurophysiological measures from valid and reliable biological signals in rehabilitation, that will help determine the neuromuscular responses associated to the level of physical frailty of the individual and his/her fall risk. However, geriatric services in general don't often have access to high-end screening tools that permit an early detection of balance problems and fall risk. Within an innovative action plan, our research program, in partnership with specialized geriatric services and researchers aims to determine the efficiency of new evaluation and intervention methods for the health of the older adults. Since 2019, this programm integrate new measures using various high-end equipment to capture biological signals enabling to perform research with patients from Hospital and patients from Parkinson Association and community local. The mission of this program is to build a new paradigm for this site while being a reference to evaluate balance/mobility and walking problems, better screen frail older adults who are at risk of falling and direct then to personalized therapy. At this time, this work will develop a longitudinal intervention study using OTAGO (PEO) exercise program. The name "OTAGO" is not an acronym, as "Otago" is a region of New Zealand located southwest of the southern island. PEO is defined by a reeducation program for strength and balance at home (or in a rehabilitation center), that is personalized, and based on conclusive data. The PEO was developed by a geriatrician (Dr. Campbell) and his team of physiotherapists in 1997, after many years of research, to identify the risks of falling and the potential interventions that could reduce these risks. The program exists worldwide but has never been tested in Québec. Although there are different fall prevention programs, conclusive data show the more frequent use of OTAGO because of its efficiency to reduce the risk of death and the incidence rate of falls over a period of one year in an aging population. This program also reduces falls by 25% according to conclusive data, which no other program in Québec and in rural areas has demonstrated until now. Finally, this program can be a cost-effective intervention for the healthcare system by reducing expenses associated to falls in rural areas, and in particular for patients in La Baie Hospital. Already used in Australia and the United States, we have yet to determine its effects in the Saguenay area. The goal is to test and show its efficiency for the fist time in the area by a random clinical trial in La Baie Hospital. This step will make it possible to advance our research program on the effective intervention plan to reduce future public healthcare expenses related to falls. The aim of this study will thus be to evaluate if the PEO, when adapted to La Baie geriatric services, is superior to conventional therapy to improve parameters of walking, balance, muscle activation, postural trunk control, mobility, force, endurance and perception of symptoms related to pain, function, fall risk and, consequently, quality of life (wellbeing), volume of medication and expenses associated to fall. In other step, the purpose is also evaluate the effect of carrying out the OTAGO exercises in an outdoor and nature modality during a feasibility study to see the impact of nature on the functional abilities of older people with neuromusculoskeletal disorders (ex. Parkinson disease).
