System Usability Scale (SUS) applied to a webbased integrated system for the management of data from people with Parkinson's disease

Parkinson’s disease (PD) is a neurodegenerative condition of the central nervous system that affects the brain and brings several different symptoms to the life of patients. Distinct exams can be done to identify and monitor the variety of health problems caused by PD, and each exam can generate a huge quantity of data. Thus, the amount of information produced needs to be managed with
organization, security, and consistency. In this work, a system so-called SIDABI was developed to manage data collected
from people with PD. The system was made available in institutions that deal with people with PD. The usability of the
system was executed by applying the System Usability Scale (SUS). This evaluation tries to bring up possible problems on
the system usability and interface. In addition, Fleiss’ kappa and Kendall’s coefficient were applied to verify the agreement
of users. The average SUS score reached 83.0 points, the Fleiss’ Kappa was 0.245, a fair concordance, and Kendall’s
coefficient was 70% of agreement between the raters. These results suggest the system provides a good experience for the user during user interaction.
