Prediction of Single Trial Somatosensory Evoked Potentials From Mechanical Stimulation Intensity

Somatosensory evoked potentials (SSEPs) are important for both scientific research and the evaluation of treatment efficacy in neurorehabilitation. SSEPs measure the response in the sensorimotor cortex to a peripheral stimulation. Individual responses are often noisy, so SSEPs have typically required hundreds of stimulation-response trials to produce a single measurement. This work presents a method to estimate single trial SSEPs from tendon hammer accelerations. While predictions from the input side can not completely replace actual measurements of SSEPs, the results produced may help to provide clinicians insight where full scale SSEP measurement is not practical.
