The objective of this study is to validate the prototype of the WeTakeCare- system in the real environment (=end users homes) and is embedded in Work-Package 4 (validation and evaluation) with the following main tasks:

T4.1. Definition of methodologies and protocols T4.2. First validation: concept assessment T4.3. Second validation: functional assessment T4.4. Third validation: real environment T4.5. Final check

Within the validation phase III of our project the investigators want to validate the contents of our fitness and information software WeTakeCare with the target group: elderly and their unprofessional caregivers. It runs on the Microsoft Kinect-System, which is authorised in Switzerland, and is in accordance with the prescribing information. The fitness- and information software contains information about strategies and devices which are available in case an older person is not able to perform the everyday movements in a safe and easy way.

Aim of the training and information software is to support elderly to stay independent from others help as long as possible. The mentioned software is not a medical or therapeutical treatment or a medical or therapeutical product. Performed exercises or presented information are highly regarded in the interest of safety and protection of the participants, and serves to prevent physical restrictions or damage .

There is only minimal risk or burden for the participants; the contents of the intervention itself (training of basic motor skills, instruction of strategies and the use of assistive devices to (partly) compensate restrictions in ADL performance, enablement of caregivers) are a standard in rehabilitation of elderly.

The investigators expect the start of the third validation in October 2015.

General study design and justification of design

Type of study: Validation of the prototype of the fitness- and information Software: WeTakeCare (pilot test) in a pre- post design, no comparators

Duration:

• Preparation of the validation study containing: recruiting, pre-screening, assessing, instructing (2-4 month)
• Validation implies the use of the system during expected 3-6 consecutive months, starting soonest in October 2015- (expected) April 2016.

Population to be studied: Healthy elderly (aged 50+) with mild to moderate restrictions in the performance of ADL and their caregivers Number of participants: Involvement of a total of 20 couples in Switzerland. Incorporating 2-5 couples in the first month to allow detection and resolution of any problem.

Study phases

1. "pre testing" of participants eligibility
2. medical check
3. first assessment (first part of baseline measurements)
4. technical installation of the system Installation of the system at the end-users homes will be realized by staff members (See team member list) from the ZHAW.
5. introduction of participants in the practical use of the system (second part of baseline measurements) To guarantee reality of the pilot it will be conducted without altering the environment except if there's environmental elements/factors posing risks to the end-users when performing the exercises/ using the program. The presence of potential risk factors will be controlled by occupational therapists, accompanying the installation of the system. If there's is any risk factor identified (i.e. reduced available space in front of the television screen), OT's (Occupational therapists) will ensure the removal. If a removal is not possible, alternate possibilities will be verified and in case of non-availability this will lead to study exclusion. After installation of the program participants will receive an initial training on functioning by occupational therapists Weekly follow-up controls will also be conducted by OT's (Occupational therapists) (short questionnaire and assessment of improvement of ADL capabilities). These OT's (Occupational therapists) will have received training in the WTC (WeTakeCare-system) use before.
6. Validation phase with a permanent digital log and weekly measurement of…..
7. final assessment (outcome measurements) Methods of minimising bias A description of the measures taken to minimize/avoid bias, including: Randomization, Blinding.

Within the pretesting phase possible participants are screened to validate the cognitive status as well as the physical condition to include only elderly and caregivers which have a benefit from participation.

STUDY INTERVENTION (SPIRIT #11) 8.1 Identity of Investigational Products (treatment / medical device) (ICH/E6 6.2.1, 6.4.2, 6.4.4; AGEK Checklist 2, item 3) Enrolled participants will get the technical appliances and support with the installation of the gadgets. (Kinect I (Microsoft-Kinect) and if necessary an appropriate Laptop) Occupational therapists will give a comprehensive instruction to the system, which also includes clarification of safety precautions.

The participants are free to use the system within their everyday life whenever they want.(Alone or together with their caregivers.)
