Our long term objectives are to understand the mechanisms of motor impairment following
neurologic injury and to develop interventions to improve motor recovery. A series of
complementary, overlapping clinical trials and development activities will validate and
optimize the use of robot-assisted upper limb therapy for neuro rehabilitation.
We have developed a robotic system that assists or resists elbow and shoulder movements in
three dimensional space. In addition to unilateral exercise modes, a novel bimanual mode
enables hemiparetic subjects to practice mirror image upper limb exercises.
Randomized controlled clinical trial of the Mirror Image Movement Enabler (MIME) robotic
device for shoulder and elbow neurorehabilitation in subacute stroke patients. MIME
incorporates a PUMA 560 robot that applies forces to the paretic limb during unilateral and
bilateral movements in three dimensions. Robot-assisted treatment (bilateral, unilateral,
and combined bilateral and unilateral) was compared with conventional therapy.
