Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Primary study objective: The main research question is how motor learning ability is influenced by preceding artificially induced, virtual reality-based sensorimotor mismatch in comparison to two other learning paradigms. Outcome measure: Behavioral motor learning success in a repeated target task using a computer mouse with the right and left hand, measured immediately after the VR training for 12 minutes per hand. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary study objectives: - Description of the cortical and subcortical processes induced by the three learning paradigms through analysis of activity and connectivity changes in functional MRI - Description of the relationship between learning success and connectivity changes - Evaluation of the impact of age and pre-existing cerebral microvascular damage on the effect of the mismatch - Comparison of side effects (simulator sickness) and user experience in the three groups including age and sex dependence Outcome measures: - Cortical and subcortical activity and connectivity changes in functional MRI (difference between two resting-state measurements before and after the intervention) - Correlation of behavioral learning success with connectivity changes - Correlation of learning success with age - Correlation of learning success with microvascular changes measured as white matter lesions in MRI - Simulator Sickness Questionnaire (SSQ), assessment using the established questionnaire following the VR training (Factors N, O, D, TS, and individual items in group comparison as well as in relation to age and gender dependence) - User experience (User Experience Questionnaire), assessment using a self-developed questionnaire following the VR training in group comparison including analysis of age and sex dependence | — |
