In our previous systematic review [SEPs are time-locked potentials evoked by electric stimulation of the sensory or mixed peripheral nerves and recorded along the large-fibre somatosensory (dorsal column–medial lemniscus) pathway [PES is a rehabilitative technology that uses electrical currents to the peripheral nerves. It has been proposed that somatosensory stimulation in the form of electromyographically triggered neuromuscular electrical stimulation to the peripheral nerve can influence functional measures of motor performance in stroke patients and produce changes in cortical excitability [Our previous review found a correlation between different FES types and changes in SEP components. However, verifying the degree of correlation between SEPs and cortical plasticity was not possible. An interesting finding was that the stroke studies involving FES that initiated a voluntary contraction used for a specific movement or task indicated a positive relationship and correlation with assessments of motor function [Therefore, for this trial, the decision was made to apply neuroprosthetic FES using the L300 Go system [The degree of correlation between SEP and cortical plasticity remained elusive due to a lack of supporting data in previous studies. However, neurophysiological measures may also have predictive value. According to Feys et al. [Our primary aim was to detect changes in pathological latencies and amplitudes of SEPs caused by an acute subcortical and cortical poststroke lesion after a 2-week FES neuroprosthesis FD treatment by observing two stroke groups during intervention and non-intervention times. In addition, an untreated control group of healthy adults underwent repeated SEP measurements for evaluation only.The second aim was to correlate the detected SEP changes with the efficacy of a 2-week FES neuroprosthesis intervention in improving FD weakness as measured by a 10-m walking test and the strength of dorsal flexion using manual muscle testing grading systems (MRC) [
