We systematically reviewed and analyzed the literature to find
randomized controlled trials (RCTs) that employed robotic devices in
upper-limb rehabilitation of people with stroke. Out of 574 studies, 12
matching the selection criteria were found. The Fugl-Meyer, Functional
Independence Measure, Motor Power Scale, and Motor Status Scale outcome
measures from the selected RCTs were pooled together, and the
corresponding effect sizes were estimated. We found that when the
duration/intensity of conventional therapy (CT) is matched with that of
the robot-assisted therapy (RT), no difference exists between the
intensive CT and RT groups in terms of motor recovery, activities of
daily living, strength, and motor control. However, depending on the
stage of recovery, extra sessions of RT in addition to regular CT are
more beneficial than regular CT alone in motor recovery of the
hemiparetic shoulder and elbow of patients with stroke; gains are
similar to those that have been observed in intensive CT.
