  1. Chronic physical activity preserves efficiency of proprioception inpostural control in older women Julien Maitre, PhD; Jean-Louis Jully, MD; Yannick Gasnier, MD; Thierry Paillard, PhD

  2. Aim • Compare effects of proprioceptive disruption on postural control for participants of different ages, according to their physical and/or sport activity levels. • Relevance • Proprioceptive impairment is associated with decreased functional ability and increased fall risk in older individuals. • Hence, optimization or preservation of proprioception is crucial in rehabilitation.

  3. Method • Participants: • 68 women grouped by age and physical and/or sport activity level: • Young active. • Old active. • Young sedentary. • Old sedentary. • Conditions: • Bipedal quiet stance (reference). • Bilateral Achilles tendon vibration. • Measures: • Center of foot pressure displacements. • Frequency analysis.

  4. Results • When proprioceptive information was disrupted, postural control disturbance was more important for old sedentary group than for other groups. • No differences between old active group and young sedentary group. • Postural control was less altered for young active group than for other groups.

  5. Conclusion • Aging decreases efficiency of postural control, regardless of assessment conditions. • Physical and sport activities may compensate for disturbing effects of proprioceptive perturbation through better use of sensory information, whatever the participant’s age.
