Remote scoring of a low-cost quantitative continuous measurement of movements in the extremities of people with Parkinson’s disease
Description
Parkinson’s disease is one of the most prevalent neurodegenerative disorders, caused by the gradual degeneration of dopaminergic cells in the substantia nigra pars compacta. It ranks as the second leading cause of death in the United States, following Alzheimer’s disease. Diagnosis of Parkinson’s disease is primarily based on physical and neurological examinations, complemented by laboratory data and structured interviews. Motor symptoms are typically assessed through visual observation by trained raters, who evaluate patients from a distance while they perform motor tasks (Goetz CG, et al. Mov Disord 2008). The use of the Movement Disorder Society Unified Parkinson’s Disease Rating Scale (MDS-UPDRS) has proven to be highly effective due to its well-structured tasks administered to patients, allowing for a detailed quantification of motor symptom severity, which plays a crucial role in designing an appropriate treatment plan. Traditionally, the MDS-UPDRS has been applied during in-person evaluations. However, due to global crises, there has been a growing need to transition to remote assessments. In a remote rating session, six trained raters, certified by the Movement Disorder Society and located across different continents, evaluated the motor symptoms of five participants aged 66.2 ± 9.2 years (range: 55–76). These participants included individuals with Parkinson’s disease (ages 72 F and 76 M) and those with typical development (ages 55 M, 58 M, and 70 M). The investigators conducted the session by sharing videos of the participants performing motor tasks via screen-sharing. The names and numbers of each test were announced prior to playing the videos for all participants. After each video session, the raters scored the following motor tasks: (3.17U: Rest tremor amplitude upper limbs, 3.17UC: Rest tremor amplitude upper limbs counting, 3.15PT: Postural tremor of the hands, 3.4FT: Finger tapping, 3.5HM: Hand movements, 3.6PS: Pronation-supination movements of the hands, 3.9U: Arising from chair upper limbs, 3.17L: Rest tremor amplitude lower limbs, 3.17LC: Rest tremor amplitude lower limbs counting, 3.7TT: Toe tapping, 3.8LA: Leg agility, 3.9L: Arising from chair lower limbs). Following each rating session, a consensus conference was held to agree on a unified score for each test. In cases where there was no initial agreement, a discussion period was allowed to reach consensus. This poster was presented at Neurology Exchange Virtual Conference, September 19-21, 2023, www.neurology-exchange.com
