What is visual scanning?
Visual scanning is a type of skill that can be used therapeutically for certain conditions that result in visual neglect. These conditions include stroke, traumatic brain injury, or brain tumors in some regions of the brain- particularly the right hemisphere (Li and Malhotra, 2015). Neglect is typically experienced on the contralateral side of a lesion, meaning that in most cases, neglect is experienced on the left side of the patient's vision due to a right-sided injury.
Visual neglect is not due to a primary sensory deficit but rather an issue of the attention paid to one side of the patient's visual field due to the neurological injury (Whitehouse et al., 2019). As such, in some cases, it can be diagnosed and potentially improved through visual scanning tools designed to identify problems and address visual perceptual skills.
Some benefits and skills can be acquired through the use of visual scanning tools to support patients with visual perceptual deficits, such as:
- Visual perceptual tracking abilities
- Fine and visual motor skills
- Hand-eye coordination
- Increased independence
