Qoos Use Sustaining Health Among patIents hOspitalized in Geriatric mediciNe (QUSHION)

Falls are a frequent and serious problem in old people. It is estimated that one-third of subjects over 65 years of age and 50% of those over 85 years of age have at least one fall per year (1). The traumatic and psychological consequences of falls contribute to the loss of functional independence and lead to early institutionalization (2). All activities of daily living require us to maintain a state of postural balance, whether standing, sitting, static or dynamic. Thus, good coordination is essential to maintain balance, reflecting both peripheral (muscular) and central (cognitive) motor control (3,4). Coordination skills between posture and movement decline during aging without associated disorder, and even more so when this aging is associated by cognitive disorders (5,6). On the contrary, as part of a balance rehabilitation program, an adapted training allows the partial recovery of the balance management process in elderly subjects who fall (7). Le Qoos® by LudHealth is technical foam equipment, which can be installed on the wall, to practice various physical exercises. It can therefore be used as a simple support, leaning on with hands, arms, feet or even the head, exerting contact points, pressures or even impacts with more or less force. Le Qoos® is an equipment that allows to perform, on the same object, gentle or tonic exercises, balance, flexibility, sheathing or muscle strengthening while having fun. We hypothesize that cognitive-physical stimulation workshops based on the use of the device Le Qoos® and is environment are i) adapted to geriatric fall prevention issues, ii) accessible to elderly hospitalized patients and health professionals, and iii) effective and safe to maintain and/or recover postural balance in elderly hospitalized patients. First step of this work is to assess whether "Le Qoos" is considered as usable par end-users of the device.
