Study summary

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.

Read the detailed 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 411 PD participants from the CVS PD cohort and 240 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.

Study population

Control cohort participants will be identified through Public and Patient Networks and Engagement teams and banks of volunteers already known to clinical sites. Control individuals may also be relatives or friends of PD participants. PD cohort participants will be recruited from the Mobilise-D Clinical Validation Study.

Eligibility criteria

Control Cohort:

Inclusion Criteria:

  • Aged 50 years or over
  • Able to walk 4 meters independently without walking aids
  • Anticipated availability for 12 months.
  • Ability to consent and comply with any study specific procedures.
  • Willingness to wear a wearable sensor for mobility monitoring
  • Able to read and write in first language in the respective country

Exclusion Criteria:

  • Occurrence of any of the following within 3 months prior to : myocardial infarction, hospitalization for unstable angina, stroke, coronary artery bypass graft (CABG), percutaneous coronary intervention (PCI), implantation of a cardiac resynchronization therapy device (CRTD), active treatment for cancer or other malignant disease, uncontrolled congestive heart disease ( class >3), acute psychosis or major psychiatric disorders or continued substance abuse, other neurological or orthopaedic impairment that significantly impacts on gait
  • Patients with a clinical diagnosis of PD, , proximal hip fracture or MS
  • History of dementia/significant cognitive impairment, or movement disorder (including essential tremor)

PD Cohort

Inclusion Criteria:

  • Participant in the Mobilise-D Clinical Validation Study (CVS) PD Cohort - see below.

CVS PD Cohort:

Inclusion criteria:

  • Aged 18 or over
  • Patients with the clinical diagnosis of PD according to the recent criteria of the Movement Disorder Society
  • Hoehn \& Yahr stage I-III

Exclusion Criteria:

  • History consistent with Dementia with Lewy Bodies (DLB), atypical parkinsonian syndromes (including multiple system atrophy or progressive supranuclear palsy, diagnosed according to accepted criteria)
  • Repeated strokes or stepwise progression of symptoms, leading to a diagnosis of 'vascular parkinsonism'
  • Drug-induced Parkinsonism
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

NYHA class (heart failure)

The New York Heart Association’s four classes of how much heart failure limits physical activity.

I
No limits: ordinary activity causes no undue tiredness or breathlessness.
II
Slight limits: comfortable at rest, ordinary activity causes symptoms.
III
Marked limits: comfortable at rest, less than ordinary activity causes symptoms.
IV
Symptoms even at rest; any activity makes them worse.

Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.

COPD

Chronic obstructive pulmonary disease: long-term lung disease that makes it hard to breathe out, including emphysema and chronic bronchitis.

What researchers measure

Primary outcomes

  1. Change in LLFDI in controls

    Change in the functional component score of the Late-Life Functional Disability Index (LLFDI) in control data. This assessment has 32 items, each with a scale from 5 (no difficulty) to 1 (unable to do). Raw scores are transformed into summary scores ranging from 0 (low level in ability) to 100 (high level of ability).

    Time frame: 12 months

  2. Change in LLFDI in PD

    Change in the functional component score of the Late-Life Functional Disability Index (LLFDI) in PD data. This assessment has 32 items, each with a scale from 5 (no difficulty) to 1 (unable to do). Raw scores are transformed into summary scores ranging from 0 (low level in ability) to 100 (high level of ability).
