Clinical Trial
Prospective analysis of the trial period for spinal cord stimulation treatment for chronic pain.
To determine patient preferences regarding the duration of trial period. ⋯ In this study, all patients could make a decision in 15 days, with successful trials requiring a shorter duration. The conversion rate was similar to rates in literature despite patients making a decision without physician input.

Comparative Study
Surrogate human tissue temperatures resulting from misalignment of antenna and implant during recharging of a neuromodulation device.
A synergistic experimental and numerical investigation has provided quantitative information on the response of surrogate human tissue temperatures to misalignment of the implant and antenna of neuromodulation devices during recharging. ⋯ Notwithstanding these increases, the lowest temperatures were attained by the Restore Ultra device for all operating conditions. The temperature levels achieved by the Precision Plus and Eon Mini devices were found to be greater than those for the Restore Ultra but their relative rankings depend on the thermal boundary conditions and the duration of the recharging period. The foregoing rank ordering was validated by a sensitivity study in which the heat transfer data inputted to the numerical simulation was varied systematically. The aforementioned comparisons correspond with identical recharging periods for all of the devices.

Subthalamic nucleus deep brain stimulation (STN DBS) is effective for treatment of levodopa-induced dyskinesias in patients with Parkinson's disease (PD). Medical or surgical procedures requiring electrocautery may require inactivation of the pulse generators to avoid damage to the lead or extension wire or possible reprogramming of the stimulators. This generally causes only mild and temporary disability. We report a patient with previously well-controlled dyskinesias who had severe and prolonged dyskinesias following reactivation of deep brain stimulation (DBS) following an orthopedic procedure. ⋯ Clinicians caring for PD patients treated with STN DBS should be aware of the possible reappearance of severe dyskinesias arising from routine inactivation and reactivation of pulse generators for medical or surgical procedures.

Comparative Study
Spinal cord stimulation: predictive parameters of outcome in patients suffering from critical lower limb ischemia. A preliminary study.
The aim of our study is to identify the assessment of metabolic and dynamic capillaroscopy parameters that may be predictive of the outcome of spinal cord stimulation in patients affected with non-revascularisable chronic critical limb ischemia. ⋯ Spinal neuromodulation is an effective therapy option in the management of patients affected by non-reconstructable chronic critical limb ischemia.
