Background and study aims
Walking difficulties are common in people with multiple long-term health conditions (MLTCs), such as diabetes, heart disease, or arthritis. These conditions can make it harder to walk, reducing mobility and overall quality of life. This study aims to develop and validate new digital mobility outcomes (DMOs) that can track walking patterns in people with MLTCs using sensors worn on the body. The main goal is to create accurate ways of measuring walking ability in real-world conditions, which could help clinicians better understand the impact of these conditions on mobility and tailor treatments accordingly.

Who can participate?
Adults aged 65 years and older with two or more long-term health conditions can participate. Both men and women are eligible to take part.

What does the study involve?
Participants will be asked to wear small sensors on their lower back and wrist during their normal daily activities. These sensors, known as Inertial Measurement Units (IMUs), will record walking-related data such as walking speed, stride length, cadence (steps per minute), and the time spent walking or being sedentary. The study has two main phases:
The first phase involves validating the accuracy of these sensors in a controlled laboratory setting.
In the second phase, participants will wear the sensors for 7 days to track their walking in real-world conditions. No medication or treatment will be provided as part of this study.

What are the possible benefits and risks of participating?
There are no direct benefits to participants. However, the information gathered may help improve monitoring of health and treatment effects in people with MLTCs. The risks of participating are minimal, as the sensors are non-invasive and pose no known health risks. Participants might experience slight discomfort wearing the sensors for extended periods, but they are designed to be lightweight and unobtrusive.

Where is the study run from?
The study is managed by Northumbria and Newcastle Universities (UK)

When is the study starting and how long is it expected to run for?
March 2024 to November 2025

Scientific titleWalking-related mobility assessment in older people with multimorbidity
Study acronymMulti-mobility
Study objectivesIn older adults with multimorbidity, walking-related digital mobility outcomes (DMOs) derived from wearable sensors (from both lower-back and wrist-worn inertial measurement units [IMUs]), can be accurately and reliably assessed and provide accurate estimates of real-world mobility patterns. It is reasoned that these DMOs will exhibit construct validity in reflecting global and disease-specific mobility impairment, enabling the development of a robust tool for holistic health status assessment.
Ethics approval(s)

Approved 11/07/2024, NHS Health Research Authority North East York Research Ethics Committee (2 Redman Place, Stratford, London, E20 1JQ, United Kingdom; +44 (0)2071048079; york.rec@hra.nhs.uk), ref: 24/NE/0131

Health condition(s) or problem(s) studiedOlder adults with multimorbidity, defined as having two or more coexisting long-term conditions
InterventionThe study involves laboratory-based technical validation, unsupervised real-world validation, and construct validation of walking-related digital mobility outcomes (DMOs) from both lower-back and wrist-worn wearable sensors.

The methodology consists of two main work packages that are focused on validating digital mobility outcomes (DMOs) using wearable sensors. The first work package comprises a technical validation study. Work package 1 is the laboratory-based validation, which initially tests algorithms for mobility assessment using lower-back and wrist-worn inertial measurement units (IMUs) against the gold-standard technique (stereophotogrammetry). Work package 2 includes a preliminary clinical validation, where the construct validity of the DMOs is examined by relating the sensor data with disease-specific and global health outcomes in multimorbid patients.
