A Concept for Extending the Applicability of
Constraint-Induced Movement Therapy through Motor
Cortex Activity Feedback Using a Neural Prosthesis.
Computational Intelligence and Neuroscience.
This paper describes a concept for the extension of constraint-induced movement therapy (CIMT) through the use of feedback of
primary motor cortex activity. CIMT requires residual movement to act as a source of feedback to the patient, thus preventing its
application to those with no perceptible movement. It is proposed in this paper that it is possible to provide feedback of the motor
cortex effort to the patient bymeasurement with near infrared spectroscopy (NIRS). Significant changes in such effortmay be used
to drive rehabilitative robotic actuators, for example. This may provide a possible avenue for extending CIMT to patients hitherto
excluded as a result of severity of condition. In support of such a paradigm, this paper details the current status of CIMT and related
attempts to extend rehabilitation therapy through the application of technology. An introduction to the relevant haemodynamics
is given including a description of the basic technology behind a suitable NIRS system. An illustration of the proposed therapy is
described using a simple NIRS system driving a robotic arm during simple upper-limb unilateral isometric contraction exercises
with healthy subjects.
