ReviewEvaluation of Abbott's BurstDR stimulation device for the treatment of chronic pain.
Burst stimulation, as described by DeRidder, is a novel waveform made up of closely spaced, high-frequency electrical impulses delivered in packets, which are followed by a quiescent period or interburst interval. Electrically generated burst waveforms were initially designed to treat neural pathology in the auditory cortex and were later applied to the spinal cord through spinal cord stimulation (SCS) devices to treat chronic pain states. ⋯ Expert commentary: Burst stimulation offers a salvage strategy for failed tonic spinal cord stimulation (tSCS), thus improving both quality of life and cost-effectiveness of SCS by reducing explant rates. The goal of this therapy is to use more than one waveform in the same device so that lost efficacy from tSCS can be salvaged.

Ischemic Ulcer Pain Is Both Nociceptive and Neuropathic Pain Based on a Discriminant Function Analysis Using the McGill Pain Questionnaire.
The McGill Pain Questionnaire (MPQ) is composed of 78 words reflecting the mechanisms underlying chronic pain conditions. Ischemic ulcer pain is generally regarded as a nociceptive and inflammatory pain condition. However, it is sometimes refractory to nonsteroidal anti-inflammatory drug (NSAID) and opioid treatment. ⋯ On the basis of this function, 9 of the 18 ischemic pain patients' complaints were classified as NeP. Ten patients received revascularization and after revascularization, 7 of 10 patients' complaints were still NeP. Our results suggest that ischemic ulcer pain should be regarded as a mixed pain condition composed of both NocP and NeP and that it might be treated with medications for NeP (e.g., pregabalin, duloxetine) in combination with NSAIDs and opioids.

Case ReportsUltrasound-guided peripheral nerve stimulation for neuropathic pain after brachial plexus injury: two case reports.
Brachial plexus injury (BPI) often causes severe neuropathic pain that becomes chronic and difficult to treat pharmacologically or surgically. Here, we describe two cases of successful treatment of BPI with peripheral nerve stimulation (PNS). ⋯ Both patients were satisfied with their improved sleep and quality of life. We conclude that PNS could be an alternative therapeutic modality for neuropathic pain after BPI as it provides direct nerve stimulation, has few complications, and is easy to perform.

Multicenter Study Observational Study
Peripheral Nerve Stimulation in the Treatment of Chronic Pain Syndromes From Nerve Injury: A Multicenter Observational Study.
Assessing the feasibility, technical implications, and clinical benefits of peripheral nerve stimulation (PNS) performed by an implantable pulse generator (IPG) located close to the stimulation site. ⋯ Successful PNS was achieved with a stimulation system designed for peripheral location. This new technology reduced the incidence of lead-related adverse events and the energy cost of the treatment.
