Mechanical Feedback Variant in BCI

The modern paradigm of neurorehabilitation of post-stroke patients includes ideomotor training using feedback of various modalities. Exoskeletons are a promising, but extremely immobile and expensive option for providing feedback. In this work, we tested mechanical feedback suitable for both hands. 6 subjects 22–33 years old took part in the tests. Training was carried out with a neural interface that controls the operation of the mechanical feedback prototype for right and left hands. The results of classification accuracy were achieved: 80±12.6
^%
(mean±standard deviation) for the right hand; 83±10.4% for the left hand. As a result of the tests, the complex of the neural interface and the mechanical feedback showed full functional ability.
