“…[94][95][96][97] A possible explanation of negative findings might be that visuomotor adaptation (ie, aftereffect) has to reach a critical threshold to affect performance in other tasks. 98 Given the high intra-and interindividual variability of individuals with USN, visuomotor adaptation induced by low power prisms (i.e., shifting the visual field of 5°, 6°or 10°)as those used in RCT studies that did not find any beneficial outcomes after PA [94][95][96][97] might be too small to produce detectable effects in all patients. The fact that the critical threshold can only be reached with prisms of high power (i.e., shifting the visual field of 10°or 12°, as those used in the above studies that found significant PA effects) might explain some negative findings.…”

Introduction: Unilateral spatial neglect (USN) is a disorder of contralesional space awareness which often follows unilateral brain lesion. Since USN impairs awareness of contralesional space/body and often of concomitant motor disorders, its presence represents a negative prognostic factor of functional recovery. Thus, the disorder needs to be carefully diagnosed and treated. Here, we attempted to present a clear and concise picture of current insights in the comprehension and rehabilitation of USN. Methods: We first provided an updated overview of USN clinical and neuroanatomical features and then highlighted recent progresses in the diagnosis and rehabilitation of the disease. In relation to USN rehabilitation, we conducted a MEDLINE literature research on three of the most promising interventions for USN rehabilitation: prismatic adaptation (PA), non-invasive brain stimulation (NIBS), and virtual reality (VR). The identified studies were classified according to the strength of their methods. Results: The last years have witnessed a relative decrement of interest in the study of neuropsychological disorders of spatial awareness in USN, but a relative increase in the study of potential interventions for its rehabilitation. Although optimal protocols still need to be defined, high-quality studies have demonstrated the efficacy of PA, TMS and tDCS interventions for the treatment of USN. In addition, preliminary investigations are suggesting the potentials of GVS and VR approaches for USN rehabilitation. Conclusion: Advancing neuropsychological and neuroscience tools to investigate USN pathophysiology is a necessary step to identify effective rehabilitation treatments and to foster our understanding of neurofunctional bases of spatial cognition in the healthy brain.

“…By contrast, one study described mixed results, as patients treated with PA showed greater improvement than Controls after treatment, but group results were indistinguishable after one month (Nys, de Haan, Kunneman, de Kort, & Dijkerman, 2008). More disappointingly, no effects additional to spontaneous recovery were measured by four studies that included a total number of 72 patients treated with prisms (Mancuso et al, 2012;Rode et al, 2015;Ten Brink et al, 2017;Turton, O'Leary, Gabb, Woodward, & Gilchrist, 2010). In addition, some positive findings are not really compelling and raise thè question of their clinical relevance.…”

Prism adaptation (PA) has been applied with mixed success as a rehabilitation method of spatial neglect. Results from many single-case and multiple case studies as well as randomised controlled trials do not produce a clear picture of the efficacy of PA. We here tested a new method of PA, by inducing adaptation effects in the virtual reality. Healthy participants were attributed to one of four groups: no deviation, 10-, 20-, or 30-degrees rightward deviation. In contrast to classical wedge prisms, we induced the visual shift progressively. Participants performed two variants of the bisection and the landmark task to measure cognitive transfer of adaptation effects. Pointing error was directly related to the degree of optical deviation, and was greatest immediately following adaptation. Transfer was only observed in the bisection tasks, and only in the 30-degrees group. Due to the gradual induction of the spatial deviation the majority of participants were unaware of the adaptation effects. These findings show that large rightward deviation may affect sensorimotor performance in healthy participants similarly to neglect patients. Moreover, the finding that only participants adapted to 30-degrees showed biased bisection performance suggests that a critical threshold must be reached in order to induce significant visuomotor transfer.

“…Improved visuospatial unilateral neglect symptoms as a result of rehabilitation may translate to improvements in the art constructive errors of painting. Some other clinical trials did not find such an effect for the prism (Barrett, Goedert, & Basso, 2012;Ten Brink et al, 2017;Turton, O'Leary, Gabb, Woodward, & Gilchrist, 2010).…”

Introduction: This study aimed to investigate the influence of neglect and the effect of Prism Adaptation (PA) combined with continuous Theta-Burst Transcranial Magnetic Stimulation (cTBS) on the art constructive errors of painting rehabilitation of stroke patients with neglect. Methods: Fourteen patients with neglect and art constructive errors of painting secondary to stroke were randomly assigned to the rehabilitation group and received PA combined with inhibitory protocol of cTBS over the intact parietal cortex; the control group received PA combined with sham cTBS for 2 weeks in 10 daily sessions. Patients have assessed for art constructive errors of painting in Figure Copying Test (FCT), and Coloring Test (CT) before and after the intervention. Art constructive errors of painting were classified into omission, deformation, size, neglect of warm colors, and perseveration of errors. Neglect was evaluated using the Line Bisection task (LBT), Figure Copying Test (FCT), and Coloring Test (CT). Results: All patients showed significant improvement in art constructive errors of painting (measured using pattern of painting’ errors in Figure Copying Test and Coloring Test), and neglect (measured using LBT, FCT, and CT) (p<0.05). Omission, neglect of warm colors, and deformation were the most frequent errors. Conclusion: Neglect and rehabilitation influences the painting system in stroke patients. Both approaches improved art constructive errors of painting and neglect symptoms.
