Primary purpose: OTHER

Brief summary: The objective is the determination of norms on healthy subjects, by age groups (20-29/30-39/40-49/50-59/60-69/70-79/80-89 years) for the posturological evaluation of four posture tests: the sensory organization test, the motor coordination test, the adaptation test, the stability limit test.

Detailed description: The objective is the determination of norms by age groups (20-29/30-39/40-49/50-59/60-69/70-79/80-89) of four tests of posture: the test of sensory organization, the test of motor coordination, the test of adaptation, the test of stability limit, of a new platform of static and dynamic posturology.

When moving within an environment, sensory information from the environment and the body is registered within the sensory systems (Hilber et al., 2018). More specifically, it is the functions of balancing and spatial orientation that are brought into play to produce behavioral responses that are adapted to different situations and to anticipate events in one's environment. It is therefore essential to establish not only posturological norms but also norms for the function of spatial orientation in order to propose a complete assessment of the postural and spatial cognitive profile of healthy subjects that can serve as a reference population.

These standards will serve as a basis for determining the pathological values during the exploration of numerous pathologies, in particular vestibular pathology, pathologies inducing balance and posture disorders (neurology, rheumatology).

The measurement of posture and variations of the center of gravity represents an important output marker, little or never taken into account in medical practice, and linked to a large number of integration processes, in particular multisensory and sensory-motor. Its parameters vary according to the sensory information received and processed related to the maintenance of balance: visual system, vestibular system, somesthesic system, visceral sensory system. Posture is also modulated by the attentional level and cognitive load. Posturography is one of the most cost-effective instruments in terms of clinical utility, particularly in the diagnosis of vestibular pathology (Stewart et al., 1999). Thus, the development of such an instrument represents an innovative and advantageous development in terms of diagnostic improvement.

the investigators will perform the standard setting according to a precise statistical approach (analysis of variance ANOVA with correlation coefficients and 95% confidence intervals to establish test-retest reliability).
