Abstract

Objectives: This paper addresses the design of an ambulatory monitoring system based on a set of wearable, wireless inertial measurementunits able to perform activity recognition for healthy individuals and Parkinson’s disease patients, as well as analyze and assess the severity oflevodopa induced dyskinesia.Material and methods: The monitoring system is composed of six Shimmer3 modules placed at different positions of the individual’s body.Both healthy individuals and one patient performed a protocol of simple daily life activities while wearing the Shimmer3 modules. As an initialstep, validity of the monitoring system in identifying healthy individuals’ activities is assessed. Data corresponding to the activities was separatedand features in both time and frequency domains were extracted. Multiple factor analysis was used to evaluate and infer the relationships betweenthe different module positions. A method of feature selection was implemented to determine the most important features, positions and sensorsincluded in the different modules. The classification of activities was done using a KNN classifier.Results: Promising results were obtained in classifying the activities of healthy individuals, with a global accuracy of 77.6%. However, certainadaptation is required for the application on Parkinson’s disease patients.Conclusion: While activity recognition for healthy individuals using this system was successful, further evaluation of the contribution of eachmodule needs to be done in order to determine optimal module positions. To validate the obtained results on Parkinson’s disease patients, a largerstudy based on more patient acquisitions is envisioned.

            <abstract xml:lang="en">Objectives: This paper addresses the design of an ambulatory monitoring system based on a set of wearable, wireless inertial measurementunits able to perform activity recognition for healthy individuals and Parkinson’s disease patients, as well as analyze and assess the severity oflevodopa induced dyskinesia.Material and methods: The monitoring system is composed of six Shimmer3 modules placed at different positions of the individual’s body.Both healthy individuals and one patient performed a protocol of simple daily life activities while wearing the Shimmer3 modules. As an initialstep, validity of the monitoring system in identifying healthy individuals’ activities is assessed. Data corresponding to the activities was separatedand features in both time and frequency domains were extracted. Multiple factor analysis was used to evaluate and infer the relationships betweenthe different module positions. A method of feature selection was implemented to determine the most important features, positions and sensorsincluded in the different modules. The classification of activities was done using a KNN classifier.Results: Promising results were obtained in classifying the activities of healthy individuals, with a global accuracy of 77.6%. However, certainadaptation is required for the application on Parkinson’s disease patients.Conclusion: While activity recognition for healthy individuals using this system was successful, further evaluation of the contribution of eachmodule needs to be done in order to determine optimal module positions. To validate the obtained results on Parkinson’s disease patients, a largerstudy based on more patient acquisitions is envisioned.</abstract>
