![]() 22 reported PA as an effective rehabilitation intervention for UN after stroke. 14 Although several studies 15–17 have reported the amelioration of neglect symptoms using PA, other studies did not detect any favorable effects of PA over control in clinical trials. Consequently, to reach the visual target, patients will need to adjust their movements toward the hemiplegic side especially the left side, resulting in better perception and sensorimotor coordinates of the neglected space. 12,13 The PA procedure comprises repetitive pointing movements toward a visual target with prismatic goggles that displace the visual field toward the side of the brain lesion. 11 in 1998, seems particularly promising. Among these modalities, prism adaptation (PA), first reported by Rossetti et al. ![]() Various treatment modalities such as visual scanning training, 8 mirror therapy, 9 and virtual reality training 10 have been proposed in clinical treatment of UN. 6,7 Therefore, it is crucial to develop therapeutic approaches to ameliorate neglect symptoms for post-stroke patients with UN. 4 In addition, the presence of UN interferes with functional recovery and is associated with a longer length of stay. 4,5 Patients with UN suffer from disability to report, apperceive, respond, or orient to stimuli that occurs in the contralesional side, which often leads to increased risk of falls and impairment of daily living activities in stroke survivors. 1–3 Symptoms of UN range from slow response to contralesional stimuli to complete lack of awareness of the spatial half. Unilateral neglect (UN), a spatial cognitive deficit, is considered one of the most common immediate outcomes of hemisphere stroke with an incidence up to 70% of right and 49% of left hemispheric strokes. These findings do not support the routine use of PA for post-stroke UN. With a meta-analysis of seven randomized controlled trials, it was found that PA yielded no greater improvement on neglect symptoms in post-stroke UN compared with placebo or no treatment.Prism adaptation (PA) has been reported to be effective on unilateral neglect (UN) however, controversy exists among different studies.These findings do not support the routine use of PA in patients with unilateral neglect after stroke. PA did not show a greater improvement on neglect symptoms in post-stroke patients with unilateral neglect, compared with placebo or no treatment. No statistical difference was observed between PA and control on the long-term effect (BIT: WMD, 1.92 BIT-B: WMD, −3.28 BIT-C: WMD, 2.66 Catherine Bergego Scale: WMD, −1.22 ). There was no significant immediate benefit of PA as measured by Behavioral Inattention Test (BIT) (weighted mean difference, 5.10 ), behavioral subset (BIT-B WMD, 3.40 ), and Catherine Bergego Scale (WMD, −0.52 ). ResultsĪ total of seven randomized trials, involving 211 participants, satisfied the inclusion criteria. Two independent reviewers performed data extraction and assessed the quality of studies using the Physiotherapy Evidence Database scale. Randomized clinical trials, published up to January 31, 2020, comparing PA with neutral goggles or no goggles were systematically searched and included. The aim of this study was to investigate the effects of prism adaptation (PA) on unilateral neglect after stroke.
