The aim of this study was to determine the efficacy and safety of intrathecal baclofen (ITB) delivered by a programmable pump for the chronic treatment of severe spasticity due to traumatic brain injury (TBI). Eight patients with severe spasticity following TBI, refractory to oral baclofen or who experienced intolerable side effects, were screened. The first five patients were enrolled in a research protocol that was approved by the Institutional Review Board for Human Research at Boston University Medical Center. ⋯ Reduction of spasticity resulted in improved levels of physical activity and locomotion and ease of care. Complications consisted of muscular hypotonia, areflexic bladder and urinary retention, erythema, and breakdown of the skin over the pump. Our results suggest that long-term intrathecal baclofen by an implanted programmable pump is a safe and effective method of treating severe intractable spasticity arising from traumatic brain injury.

This paper reports on 80 patients using dual electrode, spinal cord stimulation (SCS) over a four-year period Implant status, stimulation mode, anode-cathode configuration (array), cathode position, paresthesia overlap, explantation rates, complications, Visual Analog Scores (VAS), and overall satisfaction were examined in patients implanted with dual 8 contact, staggered, percutaneous electrodes. All patients had undergone implantation for chronic axial and extremity pain [e.g., Failed Back Surgery Syndrome (FBSS), Complex Regional Pain Syndrome (CRPS)]. Outcomes were evaluated in view of our previous reports in this same group at 24 and 30 months (1,2). ⋯ Thirty-five percent of patients with thoracic implants achieved paresthesia in the low back at 48 months. Explantation rates and overall patient satisfaction were significantly affected by painful radio frequency (RF) antenna coupling. This data supports the efficacy of dual electrodes in optimizing long-term SCS paresthesia overlap and complex pain outcomes.

The purpose of this case study was to evaluate a patient with diplegic cerebral palsy who underwent soft tissue lengthening augmented with intramuscular electrical stimulation. This is a prospective case study, pre- and post-test design. ⋯ All measured parameters, except knee extensor strength, improved during the postoperative period (baseline to 4-month follow-up) and continued to improve during the rehabilitative period (4-12 month follow-up), despite no formal therapy or home exercise program during this period. We conclude that surgical releases augmented with electrical stimulation resulted in a satisfactory clinic outcome, and may offer a new approach to the treatment of patients with cerebral palsy.

We describe a technique for the safe and aesthetically pleasing implantation of the Synergy pulse generator in the posterior iliac region for spinal cord stimulation. The technique can be applied to both thin and obese patients.

Internal infusion pumps are increasingly used as a safe method to deliver drugs in adult patients. However, a formal contraindication of this mode of therapy is the presence of a imbalance between the pump volume and the size of the abdominal wall as occurs in pediatric populations. We describe a method of implantation of an intrathecal infusion pump for baclofen therapy in a 10-year-old patient with cerebral palsy. ⋯ After three sessions, a pocket similar in size to an internal infusion pump was obtained. The result was a pump pocket with soft shaping and no edges that would not generate pressure sores or tissue tension after the pump insertion. This method could extend the use of internal infusion pumps in pediatric populations.
