Although burst spinal cord stimulation (SCS) has been reported to reduce neuropathic pain, no study has explicitly investigated how the different parameters that define burst SCS may modulate its efficacy. The effectiveness of burst SCS to reduce neuronal responses to noxious stimuli by altering stimulation parameters was evaluated in a rat model of cervical radiculopathy. ⋯ Burst SCS can be optimized by adjusting relevant stimulation parameters to modulate the charge delivered to the spinal cord during stimulation. The efficacy of burst SCS is dependent on the charge per burst.

Sacral neuromodulation has been considered as an effective treatment option for various types of chronic voiding dysfunction, but the mechanism of action has not been well understood. The aim of this study was to evaluate the effect of chronic sacral neuromodulation on isolated bladder functions in a rat model of spinal cord injury. ⋯ In our rat model of SCT, SNM seemed to alter adrenergic receptor function in the urinary bladder. Further studies are required to clarify the mechanism of these alterations at the level of bladder receptors following sacral neuromodulation.

Percutaneous peripheral nerve stimulation for chronic pain in subacromial impingement syndrome: a case series.
The objective of this study was to determine the effect of peripheral nerve stimulation (PNS) on pain reduction for those with refractory subacromial impingement syndrome (SIS) and to evaluate the association with reduced disability, impairment, and safety. Our hypotheses are that PNS will be associated with a reduction in pain, impairment and disability, and improvement in quality of life while demonstrating safety. ⋯ Intramuscular PNS for chronic shoulder pain due to SIS is a safe treatment associated with pain reduction, lower pain interference with activities of daily living, reduced disability, and improved shoulder abduction. Pain reduction is maintained for at least 12 weeks after treatment.
