An Evaluation of KELVIN, an Artificial Intelligence Platform, as an Objective Assessment of the MDS UPDRS Part III

Abstract: Background: Parkinson’s disease severity is typically measured using the Movement Disorder Society Unified Parkinson’s disease rating scale (MDS-UPDRS). While training for this scale exists, users may vary in how they score a patient with the consequence of intra-rater and inter-rater variability. Objective: In this study we explored the consistency of an artificial intelligence platform compared with traditional clinical scoring in the assessment of motor severity in PD. Methods: Twenty-two PD patients underw… Show more

“…The lower level of agreement for this site can be explained by a limitation of the model in lower severity patients: MDS-UPDRS clinical rating of 0 can only be either matched or overestimated by the model creating a tendency for an overestimation in the composite score. However, other causes are possible such as higher levels of clinician ratings variability for on-medication patients 23 or increased rater variability due to the non-clinical nature of the site 24 .…”

“…The total predicted score was calculated for each group and compared with the real group score and real total motor score. Inter-rater ICC (calculated with data from [8]) was used as gold standard performance, while a random imputation of scores was used as a control.…”

“…Background: Filipino's are the second largest sub-group of Asian Americans in the US and have greater socioeconomic and health disparities than many other Asian sub-groups. [1][2][3][4][5][6][7][8] In PD, evidence suggests that minorities and socioeconomically disadvantaged groups may have worse outcomes. [9][10][11] Compared to Chinese and Japanese PD patients, little is known about PD in the Filipino population.…”
