- Brief Summary
This study examines the feasibility and preliminary effects of user-centered exergames (video game-based physical exercise) in persons with multiple sclerosis (PwMS). The user-centered exergames were developed within a interdisciplinary team to meet the requirements of the end-users. The individualized exergames were designed for the Dividat Senso, a pressure sensitive plate connected to a personal computer and a frontal screen. This concurrent motor-cognitive training aims to improve motor and cognitive functions in an ecological valid setting. The cognitive functions are triggered by specific stimuli in the game scenarios. The video games are controlled via specific (whole body) movements as steps, weight shifting, jumps, and arm movements. The training focus is mainly on balance and coordination as well as executive functions and attention. Furthermore, the meaningful games (colorful and appealing visuals) were designed to motivate the players to move.
Participants are allocated to the either the intervention group or the control group (quasi-randomization). Participants in the intervention group perform 16 training session over a period of 4 to 8 weeks (depending on in- or out-patient). One training session lasts between 15-25 minutes. Since the difficulty of the games is adaptive to the ability level of each participant, they should neither be over- nor under-challenged. Participates in the control group continue their normal daily routine over 8 weeks. Measurements are performed before, in-between, and after the intervention period to assess feasibility parameters as well as motor and cognitive functions in all participants.
- Detailed Description
The study was designed to examine the feasibility of the intervention as well as to get preliminary results about the effects of the user-centered exergame training on motor and cognitive functions in persons with multiple sclerosis (PwMS).
The entire study last 5 months (March 2021 to July 2021) and is performed in three study locations (two rehabilitation clinics and one physiotherapy).
PwMS are informed by their local physiotherapists and research associates about the study. All interested PwMS are then screened for eligibility. A sample size of 30 PwMS is anticipated where 15 participants are allocated to the intervention group and 15 participants to the control group (quasi-randomization). Measurements are performed before, in-between, and after the intervention period to assess feasibility parameters as well as motor and cognitive functions in all participants.
Intervention group:The user-centered exergames were developed within a interdisciplinary team to meet the requirements of the end-users. The individualized exergames were designed for the Dividat Senso, a pressure sensitive plate connected to a personal computer and a frontal screen. The pressure-sensitive plate allows a precise analysis of the user's movements through several high-resolution sensors. Furthermore, this plate detects position and timing information that are then used to provide the user with real-time feedback and/or game adaptations. To support users with potential balance issues and to avoid fall events, a handrail is mounted around the plate.This concurrent motor-cognitive training aims to improve motor and cognitive functions in an ecological valid setting. The cognitive functions are triggered by specific stimuli in the game scenarios. The video games are controlled via specific (whole body) movements as steps, weight shifting, jumps, and arm movements. The training focus is mainly on multi-tasking, balance and coordination as well as executive functions and attention. Furthermore, the meaningful games (colorful and appealing visuals) were designed to motivate the players to move. Participants in the intervention group perform 16 training session over a period of 4 to 8 weeks (depending on in- or out-patient). One training session lasts between 15-25 minutes. Since the difficulty of the games is adaptive to the ability level of each participant, they should neither be over- nor under-challenged. Each participant starts the exergame training at the lowest level to get familiar with the game control system. As the exergame will automatically adapt (individual progression) during play time, participants are challenged at their individual motor and cognitive level. Furthermore, participants write down the amount, type, and duration of activities besides the exergames training in an activity diary.
Control group:Participants of the control group are instructed to continue their normal daily activities over the period of eight weeks. To evaluate the amount of active time, the participants get an activity diary where they can write down the amount, type, and duration of their activities.

Group Intervention Description Intervention Exergame Training Participants perform 16 exergame training (video game-based physical exercise) sessions over a period of 4 to 8 weeks (depending on in-patient or out-patient). Each training lasts between 15 to 25 minutes. Exergames automatically adjust the game difficulty to the abilities of the respective participant.
- Primary Outcome Measures
Name Time Method Feasibility assessed by recruitment rate Through recruitment completion, an average of 12 weeks Recruitment rate is the number of study participants compared to the number of initial planned participants
System Usability Through study completion, an average of 20 weeks The System Usability Scale interprets the system usability from 1 to 100, similar to a percentage score. A SUS score of at least 70 has to be reached to have an "acceptable" solution (52 = ok, 73 = good, 85 = excellent, 100 = best imaginable).
The SUS consists of 10 items on a 5-point Likert scale and lasts about 3 minutes.
The SUS is assessed at post-measurement.Feasibility assessed by adherence rate Through intervention completion, 4 to 8 weeks (depending on in- and outpatient) Adherence rate is the number of attended training sessions compared to the number of planned trainings
Feasibility assessed by attrition rate Through study completion, an average of 20 weeks Attrition rate is the number of dropouts
Feasibility assessed by a safety protocol Through study completion, an average of 20 weeks Safety protocol includes number of adverse events (including serious adverse events) and specific questions about safety issues
Feasibility, usability and training experience - Semi-structured interview Through study completion, an average of 20 weeks The semi-structured interview contains pre-defined questions about user's gameplay experiences related to their body, controller, experience, virtual game scenario and safety.
The interview lasts about 20 minutes and is assessed at post-measurement.
