Official title: Feasibility and Usability of Intrinsic Capacity Monitoring With an Integrated Data Eco-System for Healthy Ageing, and Its Association With Health Outcomes in Older Patients Undergoing Rehabilitation and in Older Nursing Home Residents.

Status Not yet recruiting

Clinical Trial Summary

In this study, 120 older adults (aged 65 years or older) either patients undergoing rehabilitation or older nursing home residents will be provided with an Eforto® device and the eco-System for Healthy Ageing (ISHA) mobile application to self-monitor intrinsic capacity for 4 months (if needed with assistance by an (in)formal caregiver). Preferably, the participants will use their own smartphone because mitigating smartphone-use-related issues.

The aims of the study are:

1. to evaluate the usability and feasibility of self-monitoring intrinsic capacity by using the ISHA system in rehabilitation and nursing home settings.

2. to investigate if changes and variability in intrinsic capacity as measured with ISHA are related to changes in functional ability and quality of life.

3. to explore individual trajectories of intrinsic capacity with the ISHA system.

Clinical Trial Description

Investigational device:

The ISHA digital eco-system (class IIa investigational medical device).

ISHA consists of 3 components:

1. An Eforto® device: a handheld grip work (GW) hardware device, composed of a rubber bulb, to be compressed by the user and plastic enclosure that holds the electronic components such as a pressure sensor, battery, and connectivity. A mouthpiece can be attached for respiratory capacity monitoring.

The Eforto® system was developed based on approximatively 20 years of scientific research on handgrip muscle fatigability performed by the Frailty in Ageing research department (see https://fria.research.vub.be/) and in collaboration with top-level international partners.

The Eforto® system allows self-assessment of muscle fatigability and self-perceived fatigue in older adults and functions as a monitoring tool for intrinsic capacity. It is a small device, easy to use, and suitable for home measurements as well as hospital settings. When used correctly, the measurements cause no discomfort and can be performed repeatedly. The Eforto® device connects to a smartphone application that provides verbal test instructions to the participant. The app will guide the participant during the test and automatically provide motivational cues via audio. The test results are aggregated and stored in a cloud platform where the researcher can manage subjects, access the test data and export it for further analysis.

2. Mobile application that ensures connectivity and collection of data from the Eforto® device and by which multiple guided tests for the locomotor (maximal grip strength, respiratory muscle strength, muscle fatigue resistance test & self-perceived fatigue questionnaire), sensory (hearing test (signal to noise technology) & vision test (rotating E test), cognitive (orientation test, object naming from description, animal naming & 10-words immediate and delayed recall), and psychological (resilience questionnaire) domains of intrinsic capacity can be completed. The app allows offline data collection and to synchronize with the third component, the remote monitoring platform. It serves as an interactive guidance and can be used by the subject/patient at home or assisted by a (formal or informal) caregiver.

3. The remote monitoring platform serves mainly as a dashboard for monitoring the older end-users. Its main purpose is to centralize and monitor the collected data.

Procedures:

The study will be approved by the institutional review board's and all participants will sign informed consent.

After informed consent is given, the eligibility assessment and T0 (baseline) measurements will take place. These measurements will be re-assessed after 2 months and 4 months.

During this test moments the participant will be asked to perform the ISHA-tests (intrinsic domains: vitality, locomotor, sensory, cognitive and psychological). Other tests that will be assessed are: anthropometry (body weight & height and waist & hip circumference), health status (medical history, Center for Epidemiologic Studies Depression scale (CES-D), Mini Mental State Examination (MMSE), fall incidents, hospital admissions, Mini Nutritional Assessment (MNA) and orthostatic test), Frailty (Fried Criteria), functional dependency tests (Montreal Cognitive Assessment (MOCA), basic activity of daily living (ADL) (Katz), instrumental ADL (Lawton) and Short Physical Performance Test (SPPB)), questionnaires (Sarcopenia Quality of life questionnaire (SarQol), Eq-5D-5L, International Physical Activity Questionnaire (IPAQ), health-economic questionnaire and general health questions) and technical problem/ usability, feasibility and expectations questionnaires. In the context of eligible check, the smartphone experiences and personal data e.g. sex, birth day date, living situation will be asked.

After an individual information session with training on the ISHA test battery and instructions for ISHA use in self-test mode, the participant will be instructed to perform the ISHA measurements for 4 months at their home (if needed with assistance by an (in)formal caregiver). Preferentially, the healthcare professional (occupational therapist, physical therapist, study nurse) will install the ISHA application on the smartphone of the participant. If during the individual information session, the participant is unable to correctly operate the ISHA tool, the healthcare professional will explore together with the participant whether a (informal or formal) caregiver could aid, and eventually the participant will be re-invited together with his/her informal caregiver for another information/training session. If correct use of the ISHA system by the participant and/or assistance by a caregiver is impossible, the participant will be excluded for further participation in the study.

The self-test measurements will be continued for 4 months or until withdrawal of the participant. The self-tests will be performed:

• weekly on 2 consecutive days per week for vitality capacity;

• once every two weeks for locomotor capacity, and

• once every month for sensory, cognitive, and psychological capacity.

The application will give a reminder to the participant every time he/she needs to do the ISHA measurements.

During the study, participants will be contacted every month by a researcher to register any changes in health situation as well as technical issues encountered during the self-testing. ;
