Scanning training for rehabilitation of visual field loss due to stroke: Identifying and exploring training tools in use

Abstract

Introduction Visual field loss affects one fifth of stroke survivors, limiting daily activities and reducing quality of life. Scanning training is a commonly used intervention, but there is variation in how this is delivered. This study aimed to identify the scanning training tools used in Scotland and describe their training parameters, delivery and suitability for use with stroke survivors. Method An email survey identified scanning training tools used in Scotland. Two expert panel meetings gained consensus on the motor, language and cognitive skills required to use each scanning training tool. Video capture techniques gathered objective measures of training parameters. Results Ten scanning training tools were identified. These tools used four delivery methods: paper-based, computer software, web-based and specialised equipment. They aimed to improve reading, perception or general visual skills. Fast, saccadic eye movements were most frequently targeted: two interventions also encouraged head movements. Session duration, frequency and therapist support varied considerably. The level of motor, language and cognitive skills required for each tool was determined. Conclusion Scanning training tools used in Scotland vary in delivery modality, functional abilities required for use and visual skills trained. This information will support clinical decision-making and inform future research on training effectiveness and feasibility.

The feasibility and effects of eye movement training for visual field loss after stroke: a mixed methods study

“…We tested MyHappyNeuron, NVT, Rainbow Readers and VISIOcoach. Table 1 provides a description of each intervention, derived in a previous study (Hazelton, Pollock, Walsh, et al, 2019) (for full TIDieR description see Supplementary Material 2).…”

“…Our earlier work identified therapist-supported specialist devices, paper-based tools, online training and computer programs in use to train eye movements (Hazelton, Pollock, Walsh, et al, 2019). These interventions vary in relation to the training aims, area of visual field covered, inclusion of head movements, cost, and number, duration and frequency of training sessions (Hazelton, Pollock, Walsh, et al, 2019). We lack studies which directly compare these different eye movement training devices, despite their routine clinical use.…”

Multitasking Compensatory Saccadic Training Program for Hemianopia Patients: A New Approach With 3-Dimensional Real-World Objects

“…The scientific community has joined efforts to develop effective neurovisual rehabilitation training programs for patients with homonymous visual field defects. Daily home-based computerized compensatory training programs 15 , 16 are widely used approaches to improve the quality of ocular movements, 17 reading performance, 18 and searching reaction time. 17 , 18 These programs are based on brain-plasticity theories 19 and principally combine computerized visual-searching tasks of low complexity stimuli (lights or simple 2D images, e.g., symbols, letters, or numbers) on a computer screen (2D environment), with other specific attention and computerized reading exercises, over a maximal training period of six weeks.…”

Special issue: Low vision rehabilitation

“…Visual field loss and resulting deficits in ADL and IADL is a prevalent impairment following stroke. Hazelton et al (2019) conducted an email survey to determine training tools utilized by healthcare professionals in Scotland to address visual field loss. These researchers provide an in-depth view of the most commonly used tools and further provide practitioners with procedures for using these interventions in clinical practice settings.…”
