Gait and posture disorders are very frequently found in subjects aged
65 and more, at prevalence between 25 and 30%. These are frequently caused by neuromuscular and cognitive disorders.
Number of studies have shown that 1) Vitamin D deficiency is frequent in subjects aged over 65, and can even reach 80% in the women of that group; 2) subjects suffering from Vitamin D deficiency present lower muscular, gait and execution performances, and become less able more rapidly than non-Vitamin D-deficient subjects; and 3) taking Vitamin D, combined with Calcium or not, may increase muscular force and cognitive performances. These “non-skeletal” effects of vitamin-calcic supplements are partially dependent on the initial levels of Vitamin D deficiency. The greater the deficiency, the more notable the supplements’ effects.
