Abstract
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.
