Among numerous studies on virtual reality (VR) technology for motor
rehabilitation, the majorities have only used it as a motor training system and
did not use the kinematic or kinetic information obtained as the basis for
therapeutic effect assessment. OBJECTIVE: Incorporating the kinematic and kinetic
information acquired through a robot-assisted VR system on pinch-grip training,
this study intends to propose novel motor ingredients represented as indices for
the interpretation of motor behaviors and verify the efficacy of them for the
assessment in chronic stroke. METHODS: Clinical trials were conducted on eight
stroke patients and clinical assessments were made as the objective standard.
Non-parametric test and correlation analysis were performed on results of motor
indices and clinical assessments. RESULTS: Non-parametric test indicated that 50%
of the motor indices significantly improved while the others showed a trend of
improvement, consisting with the findings in clinical assessments. Correlation
analysis showed that the three clinical assessment items were correlated to items
in the motor ingredients. CONCLUSIONS: The proposed motor ingredients gathered
from the robot-assisted VR training system were able to contribute to the
assessment of therapeutic effect in chronic stroke and were capable for the
interpretation of behavior phases.
