Restoration of natural somatic sensations to the amputees: finding the right combination of neurostimulation methods.
Front Neurosci

Unlabelled: Limb amputation results in such devastating consequences as loss of motor and sensory functions and phantom limb pain (PLP). Neurostimulation-based approaches have been developed to treat this condition, which provide artificial somatosensory feedback such as peripheral nerve stimulation (PNS), spinal cord stimulation (SCS), and transcutaneous electrical nerve stimulation (TENS). Yet, the effectiveness of different neurostimulation methods has been rarely tested in the same participants.

Background: We present our experience with spinal cord stimulation (SCS) for patients suffering from different pain conditions who subsequently developed hardware-related complications after SCS surgery. The SCS hardware-related complications may compromise the continuous SCS therapy due to partial or total hardware removal. Such situations should be avoided, and possible predisposing factors for their development should be minimized.

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.
Radiofrequency stimulation of the dorsal root ganglion as a diagnostic tool for radicular pain syndromes: six representative cases.

Department of Surgical, Pediatric and Diagnostic Sciences, University of Pavia, 27100, Pavia, PV, Italy.
Background: We discuss the diagnostic benefit of pulsed radiofrequency (PRF) of the dorsal root ganglion (DRG) in a case series of patients with different pathologies. We expand the diagnostic potential of DRG stimulation beyond paresthesia mapping by using DRG stimulation to help determine the role of the DRG in the patient's pain and narrow down the etiology. In some cases, DRG stimulation was also part of the treatment plan.

Introduction: Epidural spinal cord stimulation is a minimally invasive procedure with a growing list of indications. It has a good safety profile and analgesic effect, reduces the severity of spasticity, and activates various brain regions. The purpose of this study is to evaluate the clinical outcome of epidural spinal cord stimulation in patients with spastic syndrome and chronic disorders of consciousness resulting from severe traumatic brain injury (sTBI).
