Abstract EN
The focus of this study was to test a novel tool for the analysis of motor coordination with an altered visual input.
The altered visual input was created using special glasses that presented the view as recorded by a video camera placed at various positions around the subject.
The camera was positioned at a frontal (F), lateral (L), or top (T) position with respect to the subject.
We studied the differences between the arm-end (wrist) trajectories while grasping an object between altered vision (F, L, and T conditions) and normal vision (N) in ten subjects.
The outcome measures from the analysis were the trajectory errors, the movement parameters, and the time of execution.
We found substantial trajectory errors and an increased execution time at the baseline of the study.
We also found that trajectory errors decreased in all conditions after three days of practice with the altered vision in the F condition only for 20 minutes per day, suggesting that recalibration of the visual systems occurred relatively quickly.
These results indicate that this recalibration occurs via movement training in an altered condition.
The results also suggest that recalibration is more difficult to achieve for altered vision in the F and L conditions compared to the T condition.
This study has direct implications on the design of new rehabilitation systems.
