Introduction: Trunk control plays an important role not only for body movements, but also for vital functions, such as breathing, speaking, walking, swallowing and motor skills. In clinical practice, this has led to the need for specific trunk assessment. Trunk Impairment Scale is useful for specific evaluation of static and dynamic balance and coordination for stroke patients. Purpose: The purpose of the diploma work was to review the measurement properties of the Trunk Impairment Scale and to determine, which version is the most appropriate for clinical use. Methods: The following databases were examined: PubMed and CINAHL. Studies published in English, Slovenian or Italian were included. Results: A total of 11 studies were included in the review of the references. The second exercise of the static sitting balance (k = 0.51) and the third part (k = 0.46) of the original Trunk Impairment Scale was found to have low reliability. In addition, it was not possible to calculate the k value of the third and fourth tasks of the third part of the scale. Other versions of the Trunk Impairment Scale were found to have high or excellent reliability, with the exception of the fourth task of the second part of the Spanish Trunk Impairment Scale 2.0 (k = 0.487). An acceptable or excellent internal consistency was found in all scales. Six studies examined concurrent validity and found out good validity of the original Trunk Impairment Scale and its versions. The ceiling effect was found in the Italian version of the scale and in the original scale, while the floor effect was found only in the Norwegian version. Responsiveness was researched in the Italian version, in the original scale (AUC = 0,936), in the Fujiwara Trunk Impairment Scale (AUC = 0,883) and in the Trunk Impairment Scale 2.0 (AUC = 0,73). Conclusion: The results indicate that the Trunk Impairment Scale 2.0 is the most appropriate for evaluating stroke patients in clinical practice. It would be useful to investigate measurement properties of some of the mentioned scales, which have not been examined yet.
