 Abstract: Study systematically reviewed and analyzed the literature regarding the effectiveness of robot-assisted therapy (RT) versus conventional therapy (CT) in improving motor recovery and functional abilities of the paretic upper limb of people with stroke. Eleven scientific databases were searched 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. Results revealed that when the duration/intensity of CT is matched with that of the 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.
