Bilateral globus pallidus interna deep-brain stimulation in a patient with myoclonus-dystonia: a case report.
Myoclonus-dystonia is a movement disorder characterized by childhood onset of myoclonus and dystonia. We report a case of the epsilon-sarcoglycan mutation-negative myoclonus-dystonia patient who underwent bilateral globus pallidus interna deep-brain stimulation with subsequent improvement of both myoclonus and dystonia. ⋯ This report suggests that patients with myoclonus-dystonia may significantly benefit from bilateral globus pallidus interna deep-brain stimulation. Larger studies of this patient population are needed to confirm the optimal target.

The study aims to describe a novel cosmetic implantation technique of internal pulse generators (IPGs) for deep brain stimulation (DBS) electrodes. ⋯ Although this procedure is a little more time consuming compared with the conventional procedure, it is safe and leads to very good cosmetic results in DBS patients, which has significant benefits from the standpoint of social and work activities.

Spinal cord stimulation and dorsal column stimulation have been used successfully in the management of visceral pain for many years. A novel technique of ventral column stimulation has been used in our institute with good outcomes since 2007. We describe a retrospective series of 26 patients with visceral neuropathic pain who were treated with neuromodulation. ⋯ There is a need to further investigate the use of ventral stimulation for visceral pain syndromes. This would need multicenter trials to collect adequate numbers of patients to allow hypothesis testing to underpin recommendations for future evidence-based therapies.

The objective of this study is to present a novel surgical technique for safe placement of paddle-type spinal cord stimulation (SCS) electrode in the presence of epidural scar tissue. ⋯ SCS is a widely accepted treatment modality for chronic neuropathic pain. Placement of paddle electrode can be challenging, usually because of the presence of epidural scar tissue. There have been reported cases of spinal cord injury related to paddle electrode placement. We present a novel technique that allows for safe placement of a paddle-type SCS electrode in more challenging surgical circumstances, including the presence of epidural scar tissue.

The objective of this study is to develop a fully implanted, intramuscular, bipolar, myoelectric signal (IM-MES) recording electrode for functional electrical stimulation (FES), prosthetic myoelectric control, and other permanently implantable systems. ⋯ A fully implanted, bipolar intramuscular recording electrode (IM-MES) was developed. Implantation of the IM-MES is straightforward, and almost any muscle can be targeted. Testing has been performed to demonstrate the suitability of the IM-MES electrode for clinical use. Initial clinical applications were successful.
