This project aims at gaining insight into the role of sleep in motor learning and the first to apply sleep related learning methods in a rehabilitative setting. The primary objective is to investigate whether there is an effect of acoustic cueing during slow wave sleep on a specific motor task. The second objective is to investigate whether this effect can also be transferred to generalized motor rehabilitation outcome. Patients with an impairment of the arm function are randomized to either receiving the intervention ("cueing group") or to the control group. The patients are all listening to a melody during motor training but only the patients of the cueing group are also exposed to the melody during subsequent slow wave sleep. Performance gain is measured using an instrumented arm orthosis which is used for functional arm therapy over the sudy period of 5 consecutive days as well as during standard clinical assessments.

Primary | Improvement in specific motor task | The primary outcome will be the improvement of the task-related scores in the two motor tasks at the ArmeoSpring® device for the first part. The task scores will be provided by the software (ArmeoControl®) itself. The task scores are displayed as an ordinal scale. Higher scores display a better outcome. For the first motor task the scores are displayed as volume in m^3, for the second one it will be measured in instability in cm and hand-path ratio s unknown variable but with a target value of 1. | 5 days | |
Secondary | Correlation of motor learning curve and time of sleep cueing | The secondary outcome will be the correlation of the motor learning curve (e.g. standard clinical assessments) with the length of auditory stimulus application during the night. The standard clinical assessments like the Action Research Arm Test (ARAT) will be displayed as a score for each arm individually with a minimum of 0 and a maximum of 57 points. Higher scores indicate a better outcome. Therefore it will be analysed whether a higher length of auditory Stimulation correlates with a higher score in the ARAT. | 5 days | |
Secondary | Improvement in generalized motor rehabilitation outcome | Also the correlation of (non-) response to in-sleep cueing with the clinical parameters (e.g. ARAT on an ordinal scale) taken will be analysed. The scores of e.g. the ARAT (see above) of patients in the control and the cueing group will be compared in order to allow for a statistical analysis concerning a correlation of (non-)response to auditory stimulation during the night. | 5 days |
