    Abstract:
    INTRODUCTION: Falls in elderly people is currently a health service problem because of the multiple consequences. Numerous teams have been interested in predicting the risk of falling with clinical and instrumental tests. Our study investigated instrumental evaluation by use of the Neurocom Balance Master in the global assessment of gait problems and risk of falling in elderly people. PATIENTS AND METHODS: Transverse study concerning 60 subjects older than 65 years distributed in 2 groups of 30 subjects each according to the existence or not of falling incidents during the past year. Evaluation by the Balance Master involved the following items: 1) the modified Clinical Test for the Sensory Interaction on Balance (CTSIB), which estimates balance by measuring the speed of oscillation of the center of pressure (CP) with open then closed eyes and firm then mossy ground; 2) support monopodal 5" to the left then to the right, eyes open then closed in moderated speeds of oscillation of the CP; 3) passage from standing to sitting, in moderated speeds of oscillation of the CP; 4) limits of stability: the possibilities of moving the CP towards a predetermined target without moving the feet in moderated time and speed; 5) study of the step: determine length and width of the step as well as speed; 6) most about-turn: measure of speed of oscillation of the CP during the right then left about-turn; 7) clearing: the force of the impact and the oscillations of the CP during the clearing of an obstacle 10 cm high to measure leverage. RESULTS: The oscillation speed of the CP in the 2 groups during modified CTSIB, support monopodal 5", passage from standing to sitting, about-turn and clearing were significantly improved the group of the patients with falls (P < 0.05). The step, length and speed of these patients were significantly reduced, with no difference in width of the step between the 2 groups. In the evaluation of the limits of stability, only time necessary to reach the target was significantly increased in the group with falls. Finally, the indication of leverage and the force of impact on the ground measured by the test of clearing were more important in the group of fallers than in non-fallers. CONCLUSION: The Neurocom Balance Master estimates not only postural balance, but also the vestibulary system and reproduces the physiological conditions of daily life. It has a certain role in the early assessment of gait problems and the risk of falling. This system also allows for rehabilitation of the impaired balance and offers a profit with the biofeedback.
