A Systematic Review on Trunk Impairment Scale for Stroke Patients

Objective: The purpose of this study was to systematically review the trunk impairment scale that are used to assess the trunkcontrol of stroke patients. Design: A systematic reviewMethods: Stroke subjects were categorized as acute, subacute, chronic. In this systematic review, the studies published between2000 and 2020 were selected. A literature search using the keywords ‘QUADAS’, ‘stroke’, ‘trunk impairment scale’. Data sourcesincluded RISS, GOOGLE Scholar and DBpia. We assessed the quality of assessment tools using Quality Assessment ofDiagnostic Accuracy Studies tool. Results: We reviewed 18 studies. 7 of the 18 studies reported reliability results, 10 reported validity results. The QUADAS toolquality evaluation of 17 literatures extracted except for one randomized control test among 18 literatures showed a range of 3 to 13points. 5 of the 18 studies are presented with the Cronbach alpha coefficient indicating reliability using internal consistency, all ofwhich are more than 0.8. All studies that presented test-retest reliability, intra-rater reliability, and inter-rater reliability showedhigh agreement with an intra-class correlation coefficient of 0.75 or more. Conclusions: A systematic review of the study of the application of the trunk impairment scale for stroke patients will helpprovide criteria for future studies and application of the trunk impairment scale in clinical practice.
