In May a new add-on study of the Personalized Parkinson Project started. For this study the assessors recorded extra videos of the motorical tests from a selection of participants for a month. The add-on study is called 'audible bradykinesia'.
One of the cardinal symptoms of Parkinson’s disease (PD) is bradykinesia. Accurate evaluation of bradykinesia is essential for the correct clinical diagnosis and monitoring of the progression of PD. The evaluation of bradykinesia is done within the Movement Disorders Society Unified Parkinson’s Disease Rating Scale (MDS-UPDRS) containing four motor tasks. The interpretation of these motor tasks is known to be subjective, since clinicians give different scores to the same patient.
To quantify bradykinesia more objectively, the 'audible bradykinesia' study aims to develop a new automated quantitative tool based on the audio signals coming from the four MDS-UPDRS III motor tasks. In order to do this a total of 40 PD patients, in OFF- and ON-medication status, and 28 healthy controls were filmed during the four MDS-UPDRS III motor tasks. The results of the study are promising and will be published in the near future.
