# Motor evoked potentials for multiple sclerosis: A multiyear follow-up dataset.
|
|
|
|
|
|
# Introduction
|
|
|
-This dataset contains Motor Evoked Potential measurements, performed on Multiple Sclerosis patients.
|
|
|
+Multiple sclerosis (MS) is a chronic disease affecting millions of people worldwide. The signal conduction through the central
|
|
|
+nervous system of MS patients deteriorates. Evoked potential measurements allow clinicians to monitor the degree of
|
|
|
+deterioration and are used for decision support. We share a dataset that contains motor evoked potential (MEP) measurements,
|
|
|
+in which the brain is stimulated and the resulting signal is measured in the hands and feet. This results in time series of 100
|
|
|
+milliseconds long. Typically, both hands and feet are measured in one hospital visit. The dataset consists of 5586 visits of
|
|
|
+963 patients, performed in day-to-day clinical care over a period of 6 years. The dataset consists of approximately 100,000
|
|
|
+MEP. Clinical metadata such as the expanded disability status scale, sex, and age is also available. This dataset can be used
|
|
|
+to explore the role of evoked potentials in MS research and patient care. It may also be used as a real-world benchmark for
|
|
|
+machine learning techniques for time series analysis and predictive modelling.

# Usage
|
|
|
|
|
|
+## Downloading the dataset
|
|
|
+There are a few ways to download the dataset ([mep_dataset.zip](mep_dataset.zip)). Since it is a fairly small filesize (~300MB), it can just be downloaded through the web interface.
|
|
|
+Or from the commandline:
|
|
|
+```bash
|
|
|
+wget https://gin.g-node.org/JanYperman/motor_evoked_potentials/raw/master/mep_dataset.zip
|
|
|
+```
|
|
|
+
|
|
|
+Alternatively, you may clone the repository to your local machine, which will also include the dataset:
|
|
|
+
|
|
|
+```bash
|
|
|
+git clone https://gin.g-node.org/JanYperman/motor_evoked_potentials.git
|
|
|
+```
|
|
|
+
