Article Synopsis
- Evoked compound action potentials (ECAPs) during spinal cord stimulation (SCS) are useful for understanding pain treatment and improving SCS control, but they are affected by various artifacts like capacitive noise, EMG bleed-through, and motion artifacts.
- A study using a swine model identified these artifacts and demonstrated that they can distort ECAP recordings, making it challenging to differentiate legitimate neural signals from interference.
- The research emphasizes the need for specific controls and procedures to accurately interpret ECAP data, which is crucial for advancing closed-loop SCS technologies.
Article Synopsis
- Spinal cord stimulation (SCS) shows promise for treating chronic pain and sensorimotor disorders, but the mechanisms and electrode placement effects on spinal recordings are not fully understood.
- This study involved implanting electrode arrays in swine and used imaging techniques to analyze how electrode placement correlates with spinal anatomy and recording responses.
- The findings revealed significant differences in the spatial relationship between electrode contacts and spinal nerve rootlets, indicating that electrode placement is critical for effective stimulation and recording in the spinal cord.
Background: Epidural electrical stimulation (EES) of the spinal cord has been FDA approved and used therapeutically for decades. However, there is still not a clear understanding of the local neural substrates and consequently the mechanism of action responsible for the therapeutic effects.
Method: Epidural spinal recordings (ESR) are collected from the electrodes placed in the epidural space.
