Overview
The goal of this observational study is to investigate the ability of a mobility monitor to measure and predict outcomes in Parkinson's disease (PD). It is an extension of a previous study (the Mobilise-D Clinical Validation Study) and consists of an additional follow-up visit for PD participants and the recruitment of age matched control participants. The data will inform researchers about PD disease progression and normal changes in mobility associated with aging.
Description
This study is an extension to the Mobilise-D project which aims to develop a real world digital assessment of mobility. This Extension Study will build on the work of the Clinical Validation Study (CVS) to extend the follow-up period of the Parkinson's disease (PD) cohort and to recruit an age matched control cohort. The additional data will for allow for modelling of disease progression in PD over a longer time period and inform on progression in normal ageing.
The Mobilise-D Extension Study is an observational cohort study taking place at five clinical sites across four different countries. The study will recruit up to 551 PD participants from the CVS PD cohort and 200 age and gender matched control participants.
The PD participants will attend a single follow-up visit 36 months after their initial CVS baseline visit. The control participants will attend a baseline visit and a 12-month follow-up visit. All study visits consist of the collection of descriptive, clinical, physical, neuropsychological data. Following each visit, participants are required to wear a body worn sensor for seven days continual monitoring.
A small sample of participants will be invited to take part in a semi-structured interview (Qualitative Sub Study) to better understand participants' experiences of PD symptoms and the impact they have on mobility. The investigators also want to know if the aspects of mobility that are being measured are relevant to people with PD. These interviews will take place face to face or remotely, depending on preference.
