Pilot study on foot movement in daily life gait for fall prevention

As the number of elderly people around the world increase, much attention has been paid to research on risk factors for falls. In particular, it is known that tripping is the most common cause of falls among the elderly as they tend to utilize a shuffling gait. In recent years, the spread of wearable sensors has facilitated research on gait in daily life, and it has been discussed that it deviates from gait in the laboratory because daily life gait is affected by environmental changes, such as curves and lighting, as well as other changes, such as multitasking and fatigue. However, these studies were often limited to comparisons of indices that represent gait motion, such as gait speed and step length.
