This study compares the effects of constant current (CC) and constant voltage (CV) spinal cord stimulation (SCS) at various frequencies and intensities on standard nociceptive measurements in rats, the visceromotor reflex (VMR) and neuronal activity, during noxious visceral and somatic stimuli. ⋯ Although high-frequency CC- and CV-SCS may be more useful for the management of somatic pain, CC-SCS may be more effective for treating complex pain systems like visceral hypersensitivity.

Randomized Controlled Trial Comparative Study
A comparison of the hypoalgesic effects of transcutaneous electrical nerve stimulation (TENS) and non-invasive interactive neurostimulation (InterX(®)) on experimentally induced blunt pressure pain using healthy human volunteers.
Non-invasive interactive neurostimulation (InterX(®)) delivers high amplitude electrical pulsed currents at points of low impedance on the skin. This study compared the hypoalgesic effect of non-invasive interactive neurostimulation with transcutaneous electrical nerve stimulation (TENS). ⋯ Given the limited power of this study, we show that there were no significant differences in hypoalgesia between non-invasive interactive neurostimulation and TENS. Unlike our previous studies we also failed to detect a change pain threshold during TENS. Nevertheless, our findings can be used to inform the design of an appropriately powered study on pain patients.

The objective of this study was to demonstrate the efficacy of subcutaneous stimulation (SubQ) as an additional therapy in patients with failed back surgery syndrome (FBSS) with chronic refractory pain, for whom spinal cord stimulation (SCS) was unsuccessful in treating low back pain. ⋯ SubQ may be an effective additional treatment for chronic low back pain in patients with FBSS for whom SCS alone is insufficient in alleviating their pain symptoms.
