ExoMove - Kinematics of Daily Activities with Lower-Limb Exoskeletons

This dataset reports the lower-limb kinematics of healthy individuals during various daily activities (sitting, walking, stair ascending and descending, and transitions between them) while using two distinct lower-limb exoskeletons, eWalk and Autonomyo. The dataset captures the biomechanical differences between the exoskeletons, offering a rich resource for advancing exoskeleton design and control for assistive and rehabilitative applications.

Error Related Potential at the start of the gait with a lower limb exoskeleton

<h2>Description</h2> This dataset contains EEG signals from experiments designed to evoke Error Related Potentials (ErrP) at the onset of gait using a Brain-Computer Interface (BCI) to control a lower limb exoskeleton. The ErrP is elicited using three different stimuli: Tactile, Visual, and VisuoTactile. During the experiment, participants remain stationary and engage in two mental tasks: Relax (R) and Motor Imagery (I) of walking to activate the exoskeleton. These tasks can be executed correctly (RC, IC) or incorrectly (RE, IE). For example, during RC (Relax Correct), the subject maintains an idle state, whereas during RE (Relax Error), the exoskeleton activates unexpectedly. Conversely, in IC, the subject imagines the sensation of starting to walk in their muscles, and the exoskeleton activates, but during IE, the exoskeleton does not move despite the motor imagery. When the exoskeleton activates before starting to walk, the stimulus remains active for 2 seconds to alert the subject about the impending movement. Therefore, ErrP is elicited by the stimuli in RE and can be compared with the absence of ErrP in IC, where the stimulus activates but should not evoke an error. Each subject participates in three sessions, one for each stimulus, consisting of 12 trials. In each trial, 10 mental tasks are performed, 5 Relax and 5 Imagination, interleaved. Since the subject is never in control of the system, tasks are correctly performed 70% of the time (RC, IC), while the remaining 30% are incorrect (RE, IE). In an exception, subject R01_VisuoTactile performed 7 trials of 20 mental tasks each, 10 of each type. However, due to the extended duration of the trials and resulting fatigue, they were later split for subsequent sessions.   <h2>Data information</h2> A trial consists of a Matlab structure that stores all information related to the trial experiment.  <ul> <li>data_EEG: Original EEG signals recorded with a sampling rate of 250Hz, where each row is a channel (1-28 EEG, 29-32 EOG, 33-35 inertial electrodes).</li> <li>data_preprocessed_EEG: Matrix that contains the preprocessed signals for each channel.

Multimodal optical measurement for study of lower limb tissue viability in patients with diabetes mellitus

According to the International Diabetes Federation, the challenges of early stage diagnosis and treatment effectiveness monitoring in diabetes is currently one of the highest priorities in modern healthcare. In this experimental study, the potential of combined measurements of skin fluorescence and blood perfusion by the laser Doppler flowmetry method in diagnostics of low limb diabetes complications was evaluated. With the use of Monte Carlo probabilistic modelling, the diagnostic volume and depth of the diagnosis were evaluated. The experimental study involved 76 patients with type 2 diabetes mellitus. These patients were divided into two groups depending on the degree of complications. The control group consisted of 48 healthy volunteers. The local thermal stimulation was selected as a stimulus on the blood microcirculation system. Experimental studies have shown that diabetic patients have elevated values of normalised fluorescence amplitudes, as well as a lower perfusion response to local heating. In the group of people with diabetes with trophic ulcers, these parameters also significantly differ from the control and diabetes only groups. Thus, the intensity of skin fluorescence and level of tissue blood perfusion can act as markers for various degrees of complications from the beginning of diabetes to the formation of trophic ulcers.

Lagrangian trajectory dataset for AMOC lower limb

These Lagrangian trajectory files were generated by TRACMASS, a Lagrangian parcel tracing algorithm, using data from a high-resolution (1/12o) ocean sea-ice hindcast. Two set of experiments were performed to trace the Atlantic Meridional Overturning Circulation (AMOC) lower limb; 1) Initiated only southward trajectories across the Fram Strait (fs) that corresponds to Arctic outflow and 2) traced only northward trajectories across the easten Subpolar North Atlantic (SPNA) Section which corresponds to Atlantic inflow and associated with the North Atlantic Current (nac). _ini.csv = store positions and properties of trajectories at the starting location _run.csv = store positions and properties of trajectories during the trajectory simulation _out.csv = store positions and properties of trajectories at the ending location _rerun.csv = This file is used to select trajectories that have reached a particular ending section. Column 2 in this file contain kill zone flag. Flag 1 means trajectories reaching the surface, 2 indicates trajectories reaching the Fram Strait , 3 means trajectories reaching the eastern SPNA section and finally 4 illustrate trajectories aprroaching the Barents Sea. TRACMASS documentation is available at https://www.tracmass.org/docs.html
