Prism Adaptation Treatment for Right-Sided and Left-Sided Spatial Neglect: A Retrospective Case-Matched Study. Arch Rehabil Res Clin Transl. 2023;5(2):100263. Published 2023 Mar 21. doi:10.1016/j.arrct.2023.100263https://hdl.handle.net/1805/38152Objective: To compare the effectiveness of prism adaptation treatment (PAT) between patients with right- and left-sided spatial neglect (SN). Design: Retrospective case-matched design. Setting: Inpatient rehabilitation hospitals and facilities. Participants: A total of 118 participants were selected from a clinical dataset of 4256 patients from multiple facilities across the United States. Patients with right-sided SN (median age: 71.0 [63.5-78.5] years; 47.5% female; 84.8% stroke, 10.1% traumatic/nontraumatic brain injury) were matched 1:1 with patients with left-sided SN (median age: 70.0 [63.0-78.0] years; 49.2% female; 86.4% stroke, 11.8% traumatic/nontraumatic brain injury) based on age, neglect severity, overall functional ability at admission, and number of PAT sessions completed during their hospital stay. Intervention: Prism adaptation treatment. Main outcome measures: Primary outcomes were pre-post change on the Kessler Foundation Neglect Assessment Process (KF-NAP) and the Functional Independence Measure (FIM). Secondary outcomes were whether the minimal clinically important difference was achieved for pre-post change on the FIM. Results: We found greater KF-NAP gain for patients with right-sided SN than those with left-sided SN (Z = 2.38, P=.018). We found no differences between patients with right-sided and left-sided SN for Total FIM gain (Z=-0.204, P=.838), Motor FIM gain (Z=-0.331, P=.741), or Cognitive FIM gain (Z=-0.191, P=.849). Conclusions: Our findings suggest PAT is a viable treatment for patients with right-sided SN just as it is for patients with left-sided SN. Therefore, we suggest prioritizing PAT within the inpatient rehabilitation setting as a treatment to improve SN symptoms regardless of brain lesion side.en-USAttribution-NonCommercial-NoDerivatives 4.0 InternationalOccupational therapyPerceptual disordersRehabilitationStrokeTherapeuticsArticle
