Safety issue |
Primary |
Adverse Events |
Related and un-related adverse events during the pre-post assessments as well as during each training session will be registered |
Adverse events are assessed during the data collection period, an average of 3 to 4 weeks. |
|
Primary |
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 3-4 weeks. |
|
Primary |
Adherence rate |
Percentage of the number of attended training sessions in relation to the number of planned training sessions |
The adherence rate is assessed for all training sessions during the intervention period, an average of 3-4 weeks. |
|
Primary |
System Usability Scale (SUS) |
Participants of the intervention group will receive a survey form at the end of the intervention period regarding usability of the device used for the delivery of the exergame training (Dividat Senso) |
The SUS is completed at the post-measurement by the intervention group. The survey lasts 2 minutes. |
|
Primary |
Nasa 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. A score from 1-100 is calculated based by averaging all answers to all questions. |
The NASA-TLX is assessed after each training sessions during the intervention period. The survey lasts 1-2 minutes. |
|
Primary |
User Experience |
A questionnaire with (self-developed) questions regarding perceived enjoyment during training, perceived positive effects, intention to use after study's end etc. will be filled out by the intervention group |
The questionnaire is completed at the post-measurement by the intervention group. The survey lasts 2 minutes. |
|
Primary |
Training motivation |
Average training motivation based on motivation question in each session (Scale 1-5) answered by patients. |
The question is assessed before each training session during the intervention period, an average of 3-4 weeks.. |
|
Secondary |
Changes in psychomotor speed |
The Reaction Time Test (6-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). |
Assessment takes place at pre- and post-measurement within the two days after entry respectively before discharge. The 6-RTT lasts 5 minutes. |
|
Secondary |
Changes in mental flexibility |
To assess mental flexibility (a part of executive functions), the Trail Making Test (TMT) is used pre- and post-intervention. This paper-pencil-test is resulting in a time value in seconds. Less time needed to conducted the test is related to better performance. |
Assessment takes place at pre- and post-measurement within the two days after entry respectively before discharge. The TMT lasts ca. 10 minutes. |
|
Secondary |
Changes in inhibitory control |
To assess interference control (a part of executive functions), the Color-Word Interference Test is used pre- and post-intervention. The result is a time value measured in seconds, furthermore, errors are counted. Less time and less errors is related to better performance. |
Assessment takes place at pre- and post-measurement within the two days after entry respectively before discharge. The test lasts 10 minutes. |
|
Secondary |
Changes in selective attention |
The Go/No-Go Test conducted on the Dividat Senso measures selective attention. Participants fixate on a small grey dot in the middle of the screen. Crosses (+) and Xs (x) appear on the right and left side of the grey dot in randomised order. The task is to ignore the + and just conduct a step as quickly as possible as soon as in the direction that an x appears. |
Assessment takes place at pre- and post-measurement within the two days after entry respectively before discharge. The Go/No-Go lasts 5 minutes. |
|
Secondary |
Changes in functional mobility |
The Timed Up and Go (TUG) test is conducted. At the start signal participants must stand up from a chair, walk three meters at a comfortable walking speed, come back and sit down on the chair again. Time to complete the task in seconds is recorded. The use of walking aids is noted. |
Assessment takes place at pre- and post-measurement within the two days after entry respectively before discharge. The TUG lasts 2 minutes. |
|
Secondary |
Changes in physical performance |
To assess physical performance the Short Physical Performance Battery (SPPB) is used resulting in a total score of 12 points with a minimum score of 0 and a maximum score of 4 for each sub-test. The SPPB consist of 3 sub-tests including a balance test (e.g. tandem stance, semi-tandem stance, single leg stance), 4-meter gait test, and 5-chair rises test. A higher score means a better balance performance. |
Assessment takes place at pre- and post-measurement within the two days after entry respectively before discharge. The SPPB lasts 5 minutes. |
|
Secondary |
Changes in Single-Task Walking |
Participants have to walk a 10m distance at their preferred speed and their maximal speed while still feeling safe. |
Assessment takes place at pre- and post-measurement within the two days after entry respectively before discharge. The Single-Task Walk lasts 3 minutes. |
|
Secondary |
Changes in Dual-Task Walking |
Participants have to walk a 10m distance at their perferred speed while calculating serial sevens backwards. |
Assessment takes place at pre- and post-measurement within the two days after entry respectively before discharge. The Dual-Task Walk lasts 3 minutes. |
