Group without spinal cord injury
Adults aged 20-70 years without spinal cord injury who have chronic neuropathic pain and have undergone temporary epidural spinal cord stimulation (EES).
Neural activity will be evaluated using simultaneous spinal electrogram (SEG), electroencephalography (EEG), and electromyography (EMG) recordings during EES.

Spinal cord injury group
This cohort includes adults aged 20-70 years with chronic spinal cord injury who have undergone temporary epidural spinal cord stimulation (EES).
Participants with AIS grades A-D and injury levels from C3 to L1 will be included.
Neural activity will be evaluated using spinal electrogram (SEG), electroencephalography (EEG), and electromyography (EMG) recordings during EES.
|
This observational case-control study includes two groups: a spinal cord injury (SCI) group and a non-SCI group.
The SCI group consists of patients diagnosed with SCI by physicians.
Both groups have undergone temporary epidural spinal cord stimulation (EES), and spinal electrophysiological signals will be recorded during stimulation in the SCI group to evaluate neural activity.

Zeitfenster |
|---|---|---|
|
Peak-to-peak amplitude of spinal evoked responses
Zeitfenster: baseline; at 7、20 days after the implantation
|
Peak-to-peak amplitude of spinal evoked responses will be measured in microvolts (µV) to quantify the magnitude of neural activation under different stimulation conditions.
|
baseline; at 7、20 days after the implantation
|
|
Latency of spinal evoked responses
Zeitfenster: baseline; at 7、20 days after the implantation
|
Response latency of spinal evoked responses will be measured in milliseconds (ms) from stimulus onset to the onset or peak of the response to evaluate neural conduction characteristics.
|
baseline; at 7、20 days after the implantation
|
|
Area under the curve (AUC) of spinal evoked responses
Zeitfenster: Baseline; at 7、20 days after the implantation
|
The area under the evoked response waveform will be calculated in µV、RMT(%)) to quantify the overall neural response elicited by stimulation.
|
Baseline; at 7、20 days after the implantation
|
|
Recruitment curve of spinal evoked responses
Zeitfenster: baseline; at 7、20 days after the implantation
|
Recruitment curves will be constructed by plotting peak-to-peak amplitude (µV) to characterize spinal neural excitability and recruitment properties.
|
baseline; at 7、20 days after the implantation
|
|
EEG spectral power
Zeitfenster: baseline; 7、20 days after the implantation
|
EEG spectral power will be calculated using Morlet wavelet transform and expressed in decibels (dB) for the theta (θ), alpha (α), beta (β), and gamma (γ) frequency bands to quantify changes in neural oscillatory activity.
