<h2><b>EEG-Controlled Exoskeleton for Walking and Standing – A Longitudinal Motor Imagery Study in Healthy Adults</b></h2>
<h3><b>Dataset Overview</b></h3>
This dataset contains multimodal recordings from a brain–machine interface (BMI) training study involving seven healthy adult participants (ages 20–30; Mean = 24.3, SD = 3.8). The study examined open-loop and closed-loop control of a lower-limb exoskeleton (Rex Bionics) using EEG and inertial sensor data. Each participant completed nine sessions over several weeks, structured into a training phase and a closed-loop trial phase.
<h3><b>Experimental Design</b></h3>
<ul>
<li><b>Participants:</b> 7 healthy adults (4 male, 3 female)</li>
<li><b>Sessions:</b> 9 per participant</li>
<li><b>Training Phase:</b> Motor imagery calibration</li>
<li><b>Trial Phase:</b> Closed-loop BMI control (walk/stop)</li>
<li><b>Conditions:</b> Walk / Stop (motor imagery)</li>
</ul>
<h3><b>Task Structure</b></h3>
<p><b>Training:</b>
Participants perform motor imagery tasks without feedback to calibrate the BMI decoder.</p>
<p><b>TrialXX:</b>
Each session includes 12 closed-loop BMI trials (trial01–trial12), during which participants use motor imagery to control the exoskeleton in real time.</p>
<ul>
<li><b>Block 1:</b> Trials 1–4</li>
<li><b>Block 2:</b> Trials 5–8</li>
<li><b>Block 3:</b> Trials 9–12</li>
</ul>
<p><b>walk6min / stop6min:</b>
After the 12 trials, participants complete two extended motor imagery tasks:</p>
<ul>
<li><b>walk6min:</b> Imagining continuous walking for 6 minutes</li>
<li><b>stop6min:</b> Imagining standing still for 6 minutes</li>
</ul>
<h3><b>Data Modalities</b></h3>
<ul>
<li><b>EEG:</b> 60 scalp channels + 4 EOG channels</li>
<li><b>IMU:</b> 3-axis accelerometer, gyroscope, magnetometer, and quaternion</li>
<li><b>Sensor Placement:</b> IMUs mounted on the participant’s forehead and the exosuit back brace</li>
<li><b>Decoder Signals / Feedback:</b> Logged control signals and BMI predictions</li>
</ul>
<h3><b>Additional Materials</b></h3>
<ul>
<li><b>MIQ‑RS:</b> Motor Imagery Questionnaire – Revised Second Version (PDFs in <code>derivatives/MIQ-RS/</code>)</li>
<li><b>Validation Tables:</b> Data availability, synchronization, and electrode placement (<code>derivatives/validation/</code>)</li>
<li><b>Raw Data:</b> Provided without filtering or artifact removal</li>
</ul>
