Short postural training session improves stability in patients with age-related macular degeneration

Résumé

Objective: To explore the impact of unilateral versus bilateral age-related macular degeneration (AMD) on postural sway using a wavelet analysis, and to examine the effects of short-term postural training on postural stability in subjects with AMD. Methods: This was a cross-sectional study in which 13 subjects with unilateral AMD, 18 subjects with bilateral AMD, and 16 healthy age-matched controls participated in a short postural training session. Postural performance was measured before and after training using a force platform under seven visual conditions. We analyzed the surface area and mean velocity of the center of pressure (CoP), the postural instability index (PII), and the number of falls and collisions during postural training. Results: Bilateral AMD subjects were more unstable than healthy controls, with increased CoP surface area and PII. Visual acuity affected postural sway. After training, all subjects (both AMD and healthy) had improved postural stability. Conclusion: This study confirmed that AMD subjects are more unstable than healthy older adults, which is most likely because of their poor visual capabilities. A short training session improved postural performance in older adults (both healthy and subjects with AMD), which suggests that these subjects can use compensatory mechanisms for balance control.
