Brief Summary in Lay Language

The aim of this study is to find out if a 30 minutes training of a mental chronometry (MC) task is able to improve MC capability in subacute stroke patients. The task is to imagine how to move 15 blocks with the affected hand from one side of a box to the other side (Box-and-block Test). This Patient group also participates in a 30 minutes Training of a spatial Imagination task. The sequence of both Trainings is randomized. The interval between the Trainings is at least 3 days. Before and after each Training the Box-and-Block Test is executed as well as performed mentally. The time diffrence between execution and Imagination reprensents the Quality of MC. Our Hypothesis is that MC capability will be improved by a single MC Training but not by the Control Intervention.

Brief Summary in Scientific Language

This study explores if a single session of motor imagery (MI) training induces performance changes in mental chronometry (MC), motor execution, or changes of motor excitability.
Subacute stroke patients performed 30 minutes of a mental chronometry Training and, on a different Occasion, a Hand identification Training which requires imagery in three-dimentional space.

Interventions/Observational Groups

  •   The intervention "Mental Chronometry" comprises a mental practice for 30 minutes. Patients are asked to imagine moving blocks from one side of a box to the other side by using their affected hand.
  •   As a control intervention, patients perform the "Hand identification task" for 30 minutes. Hands are presented in different positions on a screen, and patients have to decide whether a left or a right hand was shown.

Exclusion Criteria

inability to understand the instructions, aphasia, dementia, hemianopia, spatial neglect, anosognosia, severe other illness that could interfere with the ability to participate actively.
