Introduction: There are general and specific measuring tools for gait assessment in Parkinson’s disease patients (Parkinson activity scale, freezing of gait questionnaire and rapid turns test), that help us evaluate the physiotherapeutic treatment. Purpose: To determine the measuring characteristics of gait assessment measuring tools in Parkinson’s disease patients by analyzing the literature. Methods: According to the inclusion criteria, the following literature was examined: CINHAL, PubMed (MEDLINE) and Cochrane library databases, as well as several articles from the list of literature. Results: 27 surveys were in included in the literature review. The results show that all general and specific measuring tools for gait assessment in Parkinson’s disease patients have good to excellent reliability (ICC = > 0,80; Cα > 0,80). The construct validity of general measuring tools for gait assessment – in comparison with other measuring tools - proved to be low to good (r = 0,32 - 0,75).The Parkinson activity scale and its modification show the same measurement construct (ro = 0,92). The highest correlation is seen with the Unified Parkinson´s disease scale and visual analog scale. The results of the freezing of gait quastionnaire are negligible to moderately linked to the Unified Parkinson´s disease scale (Part II and III), and moderately to well related to the item 14. The functional gait assessment is sufficiently sensitive to correctly predict the risk of falls (AUC = 0,72 - 0,86). In comparison to the general test, the instrumented timed up and go test is more sensitive to the walking disorders that occur in patients with Parkinson's disease; however it has poor reliability. Using a video, showing the episodes of freezing of gait at freezing of gait quastionnaire, does not help to better identify the freezes itself. Minimal detectable change for the 6-minute walking test is 82 meters, for dynamic gait index is 2,9 – 3,7 seconds, for instrumented timed up and go test 3,5 – 11 seconds and for Parkinson´s activity scale 2 points. Conclusion: In Parkinson’s disease patients, the following general and specific gait assessment measuring tools are fairly well-researched: intra-rater and inter-rater reliability, construct, concurrent and predictive validity, as well as minimal detectable change; however only for the on phase. The freezing of gait quastionnaire should be carefully translated into Slovene, as errors in translation may affect the measurement characteristics of the questionnaire itself.
