The main objective of this study is answering the question whether stroke patients, in solving the Parsons hemifield task, use both brain hemispheres intermixed, or that one of both is predominantly involved.

Background summary
Every year a considerable amount of elderly people are confronted with the
consequences of stroke which, for instance, can result in gait dysfunction. The
general rehabilitation method for this group of people is bottum-up. By
repeated movement execution an improve is gait is expected. The neural networks
which aid in movement execution could however also be directed top-down, by
means of motor imagery.
The last couple of years is had become clear that motor imagery and motor
execution are closely connected. Motor imagery results in i.e. activity in
partially the same brain areas as in actual motor execution. Also, other
studies have shown that repeated motor imagery (mental practice) even leads to
an improvement in motor execution.
The main question we want to answer with this study is if a Parsons hemifield
task for recognizing hands can contribute to unraveling the basic mechanisms of
motor imagery, specific what the exact role is of both brain hemispheres in
solving this task.
Study objective
The main objective of this study is answering the question whether stroke
patients, in solving the Parsons hemifield task, use both brain hemispheres
intermixed, or that one of both is predominantly involved.
Study design
The project 'Mental practice: improving gait in stroke patient in the late
stage' is a promotion traject for four years. This fourth study is an attempt
to gain more insight in the motor imagery ability of stroke patients. This
study is a continuation of the second study towards investigating motor imagery
ability in stroke patients (metc.2004.134). In this study, a clear connection
was found between hemispheric location of the brain lesion and the ability to
imagine hand movements. The current study will further aim at the question
whether in solving the Parsons hemifield task, both hemispheres contribute
equally, or that one of both has a primary role.
Study burden and risks
There are no apparent risks for the participants with this study. The extra
burden for patients is composed of imagining movements and manually pressing a
button. These activities are in no possible way damaging for the patients. They
are short in time and are performed sitting.
The MRI investigation will take up maximally 30 minutes of the patients time.
