[Changes in gait in the elderly].

Disorders of gait are a common problem in elderly people. It is estimated that over 15% of people aged over 65 years have disorders of gait. Disorders of balance are also common in old age, with increased risk of falling and lesions due to falls. Every year 20-30% of the elderly people living alone have falls. The causes of poorer control of balance in old age are not clear. Usually instability is multifactorial.
