Clinical Trial Summary

The progression of neurodegenerative disorders and the increasing number of elderly people intensifies the need of institutional care, which contrasts with the desire of most elderly and patients to live independently at home. The rapid evolution of assistive technology offers new possibilities in providing medical professionals preventive services in real-time. Therefore, the main focus of this study is on the individual sensors and how they can be combined to one unobtrusive system to assess the human behaviour and daily activities during day and night in an instrumented apartment in healthy participants.

Description:

The higher prevalence of age-associated neurodegenerative disorders (e.g. Parkinson, Alzheimer), is in line with a steady increase of the average life expectancy in Switzerland. With the progression of neurodegenerative disorders and the increasing number of elderly people, the need for institutional care intensifies, which contrasts with the desire of most elderly and patients to live independently. The rapid evolution of assistive technology offers new possibilities in providing medical professionals preventive services in real-time. An extended stay in the hospital could influence independent ageing negatively and thus, monitoring has great potential to prevent critical events. In this study, the main focus is on the individual sensors and how they can be combined to one unobtrusive system. In addition, to get an understanding which parameters of the sensors are important and how the data can be extracted and processed (algorithms). Therefore, the aim of this study is to validate the accuracy to assess human behaviour and daily activities during day and night by unobtrusive sensors in an instrumented apartment in healthy participants.

Intervention

Other:
• Monitoring by unobtrusive sensors
During the study the behavior of daily activities will be monitored by unobstructive sensors. Most of the sensors will be mounted on the wall or on furniture with direct sight to the participant and thus will not have any physical contact, except some wearables during the stay in the apartment and at home (e.g. watch, mobile polysomnography).

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Usability	The usability of the sensor system will be assessed by the System usability scale (SUS). The score range is between 0 and 100, whereas the higher score means higher usability.	Each day / 7x
Other	Doors open and closed (Activities of daily living)	Unit: 1 open, 0 closed.	1 Week / Continuously
Other	Power used - Power Plugs (Activities of daily living)	Unit: Watt.	1 Week / Continuously
Other	Temperature (Activities of daily living)	Unit: Degree Celsius.	1 Week / Continuously
Other	Relative Humidity (Activities of daily living)	Unit: Percent - Relative to a maximum humidity given the same temperature.	1 Week / Continuously
Other	Brightness (Activities of daily living)	Unit: Lux.	1 Week / Continuously
Other	Accelerometer - Wearable (Activities of daily living)	Unit: m/s^2.	1 Week / Continuously
Other	Electrocardiography (ECG) - Wearable (Activities of daily living)	Unit: Component of the ECG (QRS Complex).	1 Week / Continuously
Other	Cognition 1	Cognition will be assessed by the Montreal Cognitive Assessment (MoCA). Scores of the MoCA range from 0 to 30, with a score of 26 and higher generally considered normal.	Measured on the first day / 1x
Other	Cognition 2	Cognition will be assessed by the Mini-Mental State Examination (MMSE). Scores of the MMSE range from 0 to 30, with a score of 25 and higher generally considered normal.	Measured on the first day / 1x
Other	Health-related quality of life	Health-related quality of life will be assessed by the EuroQol (EQ-5D-5L).The EQ-5D-5L comprises five questions on mobility, self-care, pain, usual activities, and psychological status.
