Among the various applications of BCI, limb motion decoding has gained significant attention due to its potential for patients with motor impairment to regain independence and improve their quality of life. However, the reconstruction of continuous motion trajectories in BCI systems based on electroencephalography (EEG) signals remains a challenge in practical life.\n                    <jats:italic>Approach.<\/jats:italic>\n                    This study investigates the feasibility of applying feature selection and nonlinear regression for decoding motion trajectory from EEG. We propose to fix the time window, select the optimal feature set, and reconstruct the motion trajectory of motor execution tasks using polynomial regression. The proposed approach is validated on a public dataset consisting of EEG and hand position data recorded from 15 subjects. Several methods including ridge regression and multiple linear regression are employed as comparisons.\n                    <jats:italic>Main results.<\/jats:italic>\n                    The cross-validation results show that the proposed reconstructed method has the highest correlation with actual motion trajectories, with an average value of 0.511 \u00b1 0.019 (\n                    <jats:inline-formula>\n                      <jats:tex-math>\n                        \n                      <\/jats:tex-math>\n                      <mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" overflow=\"scroll\">\n                        <mml:mrow>\n                          <mml:mi>p<\/mml:mi>\n                        <\/mml:mrow>\n                      <\/mml:math>\n                    <\/jats:inline-formula>\n                    &lt; 0.05).\n                    <jats:italic>Significance.<\/jats:italic>\n                    This finding demonstrates the great potential of our approach for real-world motor kinematics BCI applications.\n                  <\/jats:p>","DOI":"10.1088\/1741-2552\/ad9cc1","type":"journal-article","created":{"date-parts":[[2024,12,10]],"date-time":"2024-12-10T17:57:01Z","timestamp":1733853421000},"page":"066039","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":7,"title":["Decoding continuous motion trajectories of upper limb from EEG signals based on feature selection and nonlinear methods"],"prefix":"10.1088","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6244-6396","authenticated-orcid":true,"given":"Shurui","family":"Li","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Miao","family":"Tian","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ren","family":"Xu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrzej","family":"Cichocki","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6133-5491","authenticated-orcid":true,"given":"Jing","family":"Jin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"266","published-online":{"date-parts":[[2024,12,27]]},"reference":[{"key":"jnead9cc1bib1","doi-asserted-by":"publisher","first-page":"131","DOI":"10.3233\/RFT-180167","article-title":"Brain computer interface for smart hardware device","volume":"10","author":"Nagarajan","year":"2019","journal-title":"Int.
