Abstract
PURPOSE: Arterial stiffness generates vascular alterations that may cause balance disorders and falls. This study aimed to investigate the possible link between arterial stiffness and postural control under different sensorial conditions in patients over 65 years. METHODS: Carotid-femoral pulse wave velocity (PWV) was measured in 47 participants aged over 65 years to evaluate their arterial stiffness (high PWV). Twenty-seven participants (mean age = 70.52 ± 4.02 years, 22 females) had a normal PWV (< 10 m s-1) and 20 participants (mean age = 75.93 ± 6.11 years; 15 females) had a high PWV (≥ 10 m s-1). Postural control was evaluated using a force platform in four postural conditions: eyes open (EO) 1, eyes closed (EC), eyes open with a dual task (DT) and eyes open again (EO2). Using sway path traveled and surface covered by the center of foot pressure, we calculate the length function of surface (LFS). This ratio provides information about the precision (surface) of postural control and the effort made (length) by the subjects. RESULTS: After an age-adjustment, LFS was lower in EO than in EC and DT in both groups (p ≤ 0.001). LFS was higher in participants with high PWV both in eyes open and eyes closed conditions (p < 0.05). LFS increased when PWV increased in EO (p < 0.01) and EC conditions (p < 0.001) but not when a dual task was performed. CONCLUSION: Difficulties in maintaining equilibrium under a dual-task condition are more pronounced in people with increased arterial stiffness. These data suggest that understanding of the influence of the arterial stiffness level on specific balance control parameters could contribute to propose better balance-oriented rehabilitation programs in older adults in an attempt to prevent fall.
