چکیده
BACKGROUND Adaptive mixed reality rehabilitation (AMRR) is a novel integration of motion capture technology and high-level media computing that provides precise kinematic measurements and engaging multimodal feedback for self-assessment during a therapeutic task. OBJECTIVE We describe the first proof-of-concept study to compare outcomes of AMRR and traditional upper-extremity physical therapy. METHODS Two groups of participants with chronic stroke received either a month of AMRR therapy (n = 11) or matched dosing of traditional repetitive task therapy (n = 10). Participants were right handed, between 35 and 85 years old, and could independently reach to and at least partially grasp an object in front of them. Upper-extremity clinical scale scores and kinematic performances were measured before and after treatment. RESULTS Both groups showed increased function after therapy, demonstrated by statistically significant improvements in Wolf Motor Function Test and upper-extremity Fugl-Meyer Assessment (FMA) scores, with the traditional therapy group improving significantly more on the FMA. However, only participants who received AMRR therapy showed a consistent improvement in kinematic measurements, both for the trained task of reaching to grasp a cone and the untrained task of reaching to push a lighted button. CONCLUSIONS AMRR may be useful in improving both functionality and the kinematics of reaching. Further study is needed to determine if AMRR therapy induces long-term changes in movement quality that foster better functional recovery.

Effect of Robot-assisted and Unassisted Reaching Exercise on Voluntary Movement in Chronic Hemiparesis
A common therapeutic approach for the rehabilitation of patients with hemiparesis involves repetitive voluntary movements with manual assistance from a therapist (“active-assist therapy”). We used a novel robotic device to deliver a controlled form of active-assist therapy in chronic stroke patients (N = 7). To examine the utility of direct mechanical assistance in rehabilitation of voluntary a...
