Aging is associated with decreased balance abilities, resulting in an increased risk of fall. In order to appreciate the visual, somatosensory, and central signals involved in balance control, sophisticated methods of posturography assessment have been developed, using static and dynamic tests, eventually associated with electromyographic measurements. We(More)
Both ankle and hip movements are used to maintain balance in strategies defined as bottom up and top down models. This suggests that pathological impairment of either of these articulations could modify the parameters of balance control. In order to appreciate the bearing of ankle damage on the proper control of equilibrium, posturographic recordings were(More)
The aim of this study was to examine ventilatory responses to training in obese adolescents. We assessed body composition, pulmonary function and ventilatory responses (among which expiratory flow limitation and operational lung volumes) during progressive cycling exercise in 16 obese adolescents (OB) before and after 12 weeks of exercise training and in 16(More)
OBJECTIVES We aimed to examine ventilatory responses during the six-minute walk test in healthy-weight and obese adolescents before and after exercise training. METHODS Twenty obese adolescents (OB) (age: 14.5±1.7 years; BMI: 34.0±4.7kg·m(-2)) and 20 age and gender-matched healthy-weight adolescents (HW) (age: 15.5±1.5 years; BMI: 19.9±1.4kg·m(-2))(More)
One thousand two hundred posturographic tests have been performed since 1988 at the Laboratoire d'Exploration Fonctionnelle ORL, Centre Hospitalier Universitaire, Nancy-Brabois, using three complementary protocols (Toennis GmBh, G). Static tests [1] measure over 20 seconds periods the displacement of the center of foot pressure (CFP) on individual standing(More)
Static and dynamic posturography was recorded in eleven professional national basketball players (complete team). This sport requires balance and skill and is practiced by tall subjects (average height: 197 cm) with a history of 10 to 15 tibio-tarsal sprains. In static tests, with eyes open or closed, the way was similar between controls and players, while(More)
The authors used a vertical force platform fitted with 4 pressure gauges (Societe Toennies). The static regime provides the statokinesigram, the lateral and sagittal stabilograms and their Fourier transformations. Information is collected with the eyes open and closed, thereby allowing the Romberg quotient to be determined. In the dynamic regime, the(More)
