失語症命名障礙之語義特徵分析治療：多特徵與少特徵變體的隨機化比較療效試驗

// A Randomized Comparative Effectiveness Trial of Many-Features and Few-Features Variants of Semantic Feature Analysis Treatment for Naming Impairment in Aphasia

隨機試驗評估語義特徵分析(SFA，列出詞彙語義特徵)對慢性中風失語命名恢復｜41人接受42小時治療（3週），出院及2–3月追蹤｜11項與5項皆改善但無差異，未治療項目改善較小，5–11項特徵數目不影響成效，具臨床指導意義

// This randomized trial tested whether the number of features participants must generate in semantic feature analysis (SFA) causally affects naming recovery in chronic post-stroke aphasia. Forty-one people were randomized to SFA requiring either 11 features or 5 features per trial, received 42 hours of treatment over 3 weeks, and were assessed on naming accuracy for treated and untreated semantically related items at exit and 2–3 month follow-up. Both groups showed large, significant gains on treated items and smaller gains on untreated items, but there were no reliable differences between the 11-feature and 5-feature groups. Therefore, manipulating the number of features per trial within the 5–11 range did not influence treatment outcomes.
