Hands-on workshops or interactive activities will allow students to understand the basic principles of the technologies, plan clinical interventions and experiments and use the devices and tools in real applications.
Students will complete two tracks of workshops (one in the early afternoon and one during the late afternoon) on June 17 (Monday), June 18 (Tuesday), and June 20 (Thursday), based on selected preference and workshop availability. The content of each workshop will span all three days, so it is necessary to attend the three days to make the most of the workshop.
July 26, 2024: SSNR2024 has now concluded, so we have closed the SSNR2024 Workshop Pre-Work page and accounts have been deactivated.
Updated: May 29, 2024 – The SSNR2024 Student Workshop Assignments have been posted! Please check this carefully, and make sure that you check out the associated Pre-Work page info so you are prepared for the workshop content. Some workshops require you to download software, scripts, and data. |
Workshop Track A (early afternoon): WS3, WS2, WS5, WS8
Workshop Track B (late afternoon): WS1, WS4, WS6
Due to low student interest and space considerations, WS7 has been changed to a talk on Jun/19/Wed morning and WS9 has been cancelled.
WS1 – High-density electromyography (HD-EMG) to investigate motor control and coordination
In this workshop, we will introduce the technique of using high-density surface electromyography (HD-EMG) to record and estimate the neural signal sent from muscles from the spinal motor neurons. Specifically, we will present methods for processing neural signals and the applications for understanding impaired motor control. Furthermore, we will provide clinical perspectives on the use of HD-EMG on pathological populations and challenges to clinical implementation. Students will be engaged in recording and processing HD-EMG signals using instruments and tools provided by the organizers. They will learn the techniques for HD-EMG recording, decomposition of the HD-EMG signals, editing of the motor neuron firings, and post-processing of motor neuron firings. Additionally, we will introduce and demo a novel real time paradigm of motor unit firing properties.

WS3 – Activity-dependent peripheral electrical stimulation for neuromodulation
This workshop provides a comprehensive understanding of the principles and techniques for using electrical stimulation for inducing neuromodulation via transcutaneous electrical nerve stimulation (TENS), e.g., sensory-specific peripheral stimulation (sPES). It will also introduce students to techniques that can be used to evaluate neuromodulation at the corticospinal (Transcranial magnetic stimulation) and spinal (H-reflex conditioning) levels. Students will learn about underlying mechanisms, physiological and anatomical principles, different parameters that can be adjusted for changing the neuromodulation effect using electrical stimulation (e.g., frequency, intensity, and duration), and how these parameters can be tailored to individual patient needs. Throughout the workshop, participants will have the opportunity to ask questions and practice the techniques (hands-on) to gain a deeper understanding of the techniques used for inducing and assessing neuromodulation.

WS8 – Machine Learning Processing for Wearable Data in Healthcare: Classification and Regression Cases in Rehabilitation Event Detection
This practical workshop presents a comprehensive overview of the usage of machine learning for processing wearable data (periodic and non-periodic time series) in healthcare settings, with application in the neurorehabilitation process. The course covers classification and regression methods to detect health-associated events, emphasizing the classification of Activities of Daily Living (ADL) using unprocessed kinematic and physiological signal data. Students will engage in neural networks, feature engineering, and data imputation and have the option to collect additional data using proprietary sensors to enhance their analytical pipelines. The workshop introduces the concept of variational autoencoders for condensing data into a conceptually informed latent space. This method is designed to isolate attributes into vectors specific to different health condition tracking from the cardiovascular effort to integrated neurorehabilitation recovery within an attribute graph. These methods aim to achieve decision-making support for physicians. The course will provide hands-on experience in evaluating this model using multimodal wearables and health records, focusing on detecting ADLs and regression of cardiovascular effort from existing datasets. This practical application will allow students to explore machine learning’s potential to improve clinical outcomes through precision neurorehabilitation.
