Basic yoga moves could help prevent falls in women over 65 years old, finds a new pilot study. Researchers examined the gait and postural stability of 24 elderly females who were enrolled in an Iyengar yoga program specifically designed for those over 65. They found that at the end of the nine-week program, participants had a faster stride, an increased flexibility in the lower extremities, an improved single-leg stance and increased confidence in walking and balance.
