Facteurs de prédiction des chutes chez les personnes âgées : relation entre qualité du contrôle postural et risque de chutes

Abstract : A poor postural stability in older people is associated with an increased risk of falling. Posturographic and clinical tool have widely been used to assess balance control; however their value in predicting falls remains unclear. The purpose of this prospective study was to determine the predictive value of posturography in the estimation of the risk of falls, including a comparison with standard clinical balance tests, in healthy non-institutionalized persons aged over 65. Postural control was evaluated by posturographic static and dynamic tests and Sensory Organization Test (SOT) and by clinical balance tests (Timed Up & Go test, One-Leg Balance, Sit-to-Stand-test) in 206 elderly subjects. Subsequent falls were monitored prospectively with self-questionnaire sent every four months for a period of 24 months after the balance testing. Loss of balance during the last trial of the SOT sensory conflicting condition was the best factor to predict risk of recurrent falls and intrinsic falls. Multiple drugs use and history of falls were associated with risk of falls. Clinical balance tests, static tests and dynamic tests revealed no significant differences between the groups. In a sample of non-institutionalized older persons aged over 65, posturographic evaluation by the SOT, especially in sensory conflicting condition, appears to be a more sensitive tool to identify those at high risk of recurrent falls or risk of intrinsic falls.
