Assessment of Motivity in People Aged 65 to 86 Years

Assessment of Motivity in People Aged 65 to 86 Years : Comparison of a Standard Assessment Versus a Technological Solution

The ability to walk is one of the fundamental attributes of human beings. However, with advancing age this ability is modified by a combination of physiological and pathological aging.These changes mainly involve an irregularity of the pitch, reducing the length of the stride, instability and a decrease in walking speed (Beauchet et al., 2002). Tinetti, Speecheley, Ginter (1988, from Ch Wider, F. Vingerhoets, J Bogousslavsky, 2005) show that 20-30% of heathly older fall each year and state that one of these falls, 25% result in injuries with significant effect and 5% a fracture. In addition to the risk of fracture fear of falling exists in many older people even before a drop in effective (Recommandation of HAS, 2005).In France, about 9 000 deaths of people aged over 65 are associated each year with a fall and this association increases rapidly with advancing age in both sexes. It is therefore important in terms of public health, learn to recognize the gait disturbance, to prevent and to make adequate assessments to reduce the risk of falls. Tools exist to assess the risk of falling. Some are comprehensive but time-consuming and are generally discarded in favour of other simpler tests (test of Tinetti or get up and go test). However, the listing of these lacks precision, particularly in terms of duration single timer.To overcome these biases, innovative technology solutions seem to be a good way. In this study, the investigators will use the motorized go-cart developed by INRIA, entitled ANG (for Assisted Navigation Guide), to obtain more reliable and accurate measurements of parameters such as walking speed and direction. Thus, the investigators set the main objective, to compare a standard evaluation of the process to a technology assessment, in participants aged 65 to 86 years. And as secondary objectives : evaluate the acceptance of using go-cart ANG in the elderly, develop an index of walking and test the feasibility of detecting a weakness of the knee joint by ANG undetected at clinic.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Walking speed.	Walking speed. This will be calculated from an exercise where participants will be asked to walk from one point to another of the room according to the instructions set out below. The average speed of walking in technology assessment, will be directly collected by ANG. A comparison of estimated speeds as standard and technology can then be performed.	one day

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
acceptance of the go-cart	to assess the acceptance of ANG in the elderly. A questionnaire after the experiment will determine the level of acceptance of the go-cart, and to assess its ease of use.; Develop mathematical algorithms to index certain characteristics of the market depending on the linear trajectory, U-turns. c) The detection of a weak joint. d) The index of walking on a path set will be made with and without use of the go-cart. e) Evaluate the ability of subjects to perform complex and precise trajectories	one day
