What does the term "trailing" refer to in relation to the diagonal technique?

The term "trailing" in relation to the diagonal technique refers to using the cane to sense obstacles behind. This technique involves employing the white cane strategically to gather information about the environment, particularly from behind the user. By trailing the cane along the ground or surface, individuals can detect obstacles or changes in the terrain that may not be easily seen due to their visual impairment. This method enables safer navigation and enhances awareness of surroundings.

The trailing technique is especially useful in situations where a clear line of sight is not available, as it helps the individual maintain orientation and avoid potential hazards that may be behind them. Furthermore, it fosters independence by allowing the user to be more engaged with their environment.

Other choices pertain to different concepts within mobility training. For instance, maintaining continuous contact with the ground relates to ensuring that the cane provides consistent feedback about the walking surface. Following a straight line with the cane is associated with directional navigation rather than assessing the area behind. Extending the cane forward while walking focuses on detecting obstacles that are directly in front of the user. Each of these actions serves a purpose, but they do not specifically define the trailing technique as it relates to sensing stimuli behind the individual.
