The goal of this clinical study is to test feasibility and effectiveness of a personalized, home-based motor-cognitive training program in community-dwelling older adults with prescription for rehabilitation.
Participants will conduct a motor-cognitive intervention program which is based on exergames (=interactive video games controlled by body movements), added to usual care for 2 weeks in rehabilitation centers (face-to-face supervision) and for 10 weeks at home (remotely supervised).
Researchers will compare an intervention group and a control group to compare possible effects of the home-based study intervention to the effect of usual care alone on cognition, physical functions, and balance confidence.
Age-related declines in physical and cognitive functioning and the associated adverse outcomes such as restricted mobility, cognitive impairment, and falls ultimately result in a decrease of older adults' quality of life. In the light of the demographic change, these age-related declines gain special importance. Attempting to counteract these declines, previous studies have revealed that simultaneous motor and cognitive training may be equally or even more effective than separate training. In fact, simultaneous motor-cognitive training has shown to improve various physical, cognitive, and psychological functions in older adults - for instance balance, gait, executive control, processing speed, exercise enjoyment, depressive symptoms, and quality of life. However, most training programs are provided face-to-face, and accessibility is a major concern for older adults, especially in the post-pandemic era. Besides, due to the demographic change there is an increased need for long-term care/treatment challenging the health care system (in terms of finance, time, and personnel). Home-based rehabilitation programs offer a cost-effective solution to these problems.
However, previous research either investigated home-based training approaches based on separate motor-cognitive training, or, in case of simultaneous motor-cognitive training approaches, these have been tested in rather specific older populations (e.g., stroke survivors, Parkinson patients, older adults with cognitive impairment) or in healthy older adults. Yet, simultaneous motor-cognitive training in the home setting should be feasible and effective in a broader population of older adults especially in those without long-term access to traditional rehabilitation interventions accompanying them to full recovery. For this reason, this study aims to test the feasibility of a personalized, simultaneous motor-cognitive home-based training approach based on exergames for geriatric patients and to evaluate its effectiveness compared to usual care alone on physical and cognitive functions as well as on fall-related self-efficacy.
Potential participants will be screened and if eligible, asked if they are interested in partaking. All eligible and interested possible participants will be orally informed about the study and receive a written study information explaining the aim of the study, procedures, risks, and benefits of participation, as well as their rights and duties in case of participation. All participants will sign a written consent form, before any study-specific actions are performed.
The study will start with a baseline assessment. Then, participants will be randomized to either the intervention or the control group applying permuted block randomization. Subsequently, participants of the intervention group will perform 6 supervised, personalized motor-cognitive training sessions in a rehabilitation centre (ideally within 2 weeks) for about 20-30 minutes per session (familiarization period). Afterwards, participants of the intervention group will continue the training independently at home for 10 weeks, 3 times/week for about 20-30 minutes with the investigators supervising them via phone calls and regular personal visits. Physical and cognitive tests will be the basis for individual training plans which will further on be regularly adapted based on progression rules. All motor-cognitive training sessions in both intervention phases will be additional to usual care. The control group receives no additional training besides usual care. Participants of all groups will conduct 3 measurement sessions: (1) T1 (baseline assessments), (2) T2 (pre-intervention, after familiarization period, before starting the home-based training), (3) T3 (post-intervention assessment).

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Intervention group | Experimental | The intervention group will conduct a motor-cognitive training program added to usual care. The intervention starts with a familiarization period in rehabilitation centers (face-to-face supervision) for 2 weeks before participants of the intervention group continue it at home (under remote supervision) for 10 weeks with 3 training sessions per week for about 20-30 minutes. Besides, participants of the intervention group will participate in 3 assessment sessions: (1) T1 (baseline assessments), (2) T2 (pre-intervention, after familiarization period, before starting the home-based training), (3) T3 (post-intervention assessment). |
|
| Control group | No Intervention | The control group will continue with their usual care. Apart from that, they will only attend 3 assessment sessions: (1) T1 (baseline assessments), (2) T2 (pre-intervention, after familiarization period, before starting the home-based training), (3) T3 (post-intervention assessment). |

| Personalized, home-based motor-cognitive training | Other | The simultaneous motor-cognitive training in this study will be conducted in form of exergames (interactive video games) using Senso hardware (DIV-SENSO-H, Dividat GmbH, Schindellegi, Switzerland) - a stepping platform with 5 pressure sensitive plates which is connected to a screen. For the home-based training, a more mobile version of the Dividat Senso will be used: a foldable pressure-sensitive mat. In both devices, stimuli of exergames appear on the screen and the participants have to react by stepping in one of 4 directions (front, back, left, right). The motor-cognitive training approach allows targeting different cognitive functions such as attention, executive functions, memory, and visuo-spatial functions as well as balance, and strength. FITT-VP principles will serve as a guideline but based on the functional status of each participant (physical and cognitive), the training sessions will be personalized in terms of training content, intensity and duration. |
| Measure | Description | Time Frame |
|---|---|---|
| Adherence rate | The duration of completed training sessions as percentages of the recommended duration of training sessions. | The adherence rate is assessed for all training sessions during the home-based intervention period, approximately for 10 weeks |
| Attrition rate | Number of participants lost during the trial will be recorded (drop-outs in both groups) | The attrition rate is assessed during the data collection period, an average of 12 weeks |
| Exergame Enjoyment Questionnaire (EEQ) | The EEQ will be used to measure exergame enjoyment in participants of the intervention group. The questionnaire consists of 20 statements rated on a five-point Likert scale which results in a minimum possible score of 20 and a maximum possible score of 100. A higher score reflects greater exergame enjoyment. | The EEQ is completed by the intervention group at T3 (post-measurement), thus about 12 weeks after study entry. The survey lasts 5-10 minutes |
| Measure | Description | Time Frame |
|---|---|---|
| National Aeronautics and Space Administration-Task Load Index (NASA-TLX) | The NASA-TLX is a self-report, multidimensional assessment tool that rates perceived workload in order to assess a task, a system, or other aspects of performance (in this case the DIVIDAT exergames). It contains five subscales: Mental Demand, Physical Demand, Temporal Demand, Performance, Effort and Frustration. Each subscale can be given a score between 0 and 20. A higher score reflects a higher workload. |

| The NASA-TLX is completed by the intervention group at T3 (post-measurement), thus about 12 weeks after study entry. The survey lasts 5-10 minutes. |
| Additional instructions | It will be noted by the investigators whether additional instructions were required by the participants of the intervention group, meaning the instructions provided by the system were not enough. | Additional instructions will be collected throughout the whole home-based intervention period, an average of 10 weeks |
| Help requests | The number of help requests by the participants of the intervention group will be noted by the investigators (e.g. in case of technical problems and understanding difficulties) | The number of help requests will be collected throughout the whole home-based intervention period, an average of 10 weeks |
| Intention to continue the training program | The intention of participants of the intervention group to continue a similar home-based motor-cognitive training program after the project will be assessed with a single question. Answer will be given on a 5 point Likert scale (1=strongly disagree, 5=strongly agree) | The assessment will take place at T3 (post-measurement), thus about 12 weeks after study entry. The survey takes about 30 seconds. |
| Changes in psychomotor speed | The Reaction Time Test (RTT) conducted on the Dividat Senso measures psychomotor speed in terms of reaction to visual stimuli using the lower extremities in 6 directions (front right, front left, right, left, back right & back left). Reaction time is measured [ms]. | The assessment takes place at T2 (pre-measurement) and T3 (post-measurement), thus about 2 and 12 weeks after study entry. The RTT lasts 5 minutes. |
| Changes in selective attention | To assess selective attention, the Go-Nogo Test will be conducted on the Dividat Senso. It evaluates the ability to suppress a response in the presence of irrelevant stimuli as well as the response latency during stimulus selection. Participants will be asked to react as fast as possible when a cross (x) is presented on the screen. However, in case the stimulus is a plus (+), they must remain still. Reaction time is measured [ms]. | The assessment takes place at T2 (pre-measurement) and T3 (post-measurement), thus about after 2 and 12 weeks after study entry. The GoNogo Test lasts 5 minutes. |
| Changes in cognitive flexibility | Cognitive flexibility will be assessed with the Flexibility Test conducted on the Dividat Senso. The test assesses the flexibility of focused attention. Participants are instructed to react with a step towards a rounded figure and then an angular figure in an alternating manner. Reaction time is measured [ms]. | The assessment takes place at T2 (pre-measurement) and T3 (post-measurement), thus about 2 and 12 weeks after study entry. The Flexibility Test lasts 5 minutes. |
| Changes in static balance | Static balance will be assessed with the Sway Test conducted on the Dividat Senso. Participants are instructed to stand as still as possible for 30 seconds. Movements of the COP are collected [in mm] - the shorter the better is the static balance. | The assessment takes place at T2 (pre-measurement) and T3 (post-measurement), thus about 2 and 12 weeks after study entry. The Sway Test lasts about 1-2 minutes. |
| Changes in dynamic balance | Dynamic balance will be assessed with the Coordinated Stability Test conducted on the Dividat Senso. At the beginning, participants are instructed to stand follow a shown figure with the COP. The trace length of the COP is recorded [in mm] - longer length means less dynamic balance. | The assessment takes place at T2 (pre-measurement) and T3 (post-measurement), thus about 2 and 12 weeks after study entry. The Coordinated Stability Test lasts about 4 minutes. |
| Changes in functional balance | To assess functional balance, the Timed up and go Test (TUG) will be performed. It requires the participant to rise from a standard arm chair, walk 3 meters at a comfortable walking speed, turn, return, and sit down on the chair again. Time to complete the task is recorded in seconds. | The assessment takes place at T2 (pre-measurement) and T3 (post-measurement), thus about 2 and 12 weeks after study entry. The TUG tests take about 2 minutes. |
| Changes in functional balance and dual task | To measure dual task, the TUG dual task (TUG-DT) will be performed. Thereby, the motor task of the TUG test (getting up from a chair, walk three meters, come back and sit down again) will be complemented with a cognitive task. For the cognitive task, participants are instructed to count backwards from 90, subtracting 7 successively. The time until the patient is fully seated again is recorded. Then, the dual task cost will be calculated by determining the percentage at which the cognitive task interfered on the test performance (DTC [%] = 100*(simple task score - DT score)/simple task score). | The assessment takes place at T2 (pre-measurement) and T3 (post-measurement), thus about 2 and 12 weeks after study entry. The TUG-DT takes about 2 minutes. |
| Changes in strength (Lower limb power) | Strength/Lower limb power will be assessed with the 30 seconds Sit-to-Stand Test (STS). The participants will start sitting on a chair and after a countdown, they must stand up straight and sit down again as many times as possible within a time frame of 30 seconds. Meanwhile, the number of times the patient fully stands up from the chair will be counted. | The assessment takes place at T2 (pre-measurement) and T3 (post-measurement), thus about 2 and 12 weeks after study entry. The STS tests takes about 2 minutes. |
| Changes in balance confidence | Balance confidence will be assessed with the Activities-specific Balance Confidence (ABC) Scale. The ABC Scale is measuring fall associated self-efficacy of a person in different activities and situations (e.g. stair climbing and walking on icy pavements).The scale is a 0% to 100% continuous response scale. The overall score is calculated by adding the item scores and dividing the total by 16 (i.e. the number of items). This total score ranges from 0% to 100% with.0% reflecting no confidence and 100% reflecting complete confidence. | The assessment takes place at T2 (pre-measurement) and T3 (post-measurement), thus about 2 and 12 weeks after study entry. The survey lasts about 10 minutes. |
