Colonic electrical stimulation (CES) may have a therapeutic potential for slow transit constipation (STC). This study aimed to evaluate the effects of implantable CES on gastrointestinal transit and defecation, and explore its mechanisms in a canine STC model. ⋯ This double-site implantable CES can improve the gastrointestinal transit and defecation in a canine STC model, possibly by activating the cholinergic and nitrergic pathways. The CES mode used in this study may be proven feasible in treating STC.

Investigate whether electrical stimulation of the spinal cord adapted to trigger locomotor patterns additionally influences dorsal horn networks. ⋯ These data suggest that neuro-electrostimulation protocols can simultaneously activate functionally distinct spinal neuronal circuits.

In a bladder overactivity model of cystitis induced by intravesical infusion of acetic acid (a.a.), several parameters of spinal nerve stimulation (SNS) were optimized using continuous infusion cystometry. The optimal stimulation was further characterized through measurements of urodynamic function using single-fill cystometry. ⋯ SNS significantly attenuates hypersensitive micturition reflex; 10 Hz and high-intensity stimulation are mostly effective. Acute peripheral nerve activation increases the functional bladder capacity, which may be via mechanisms on the afferent arm of the bladder micturition reflex.

Coordinating Upper and Lower Body During FES-Assisted Transfers in Persons With Spinal Cord Injury in Order to Reduce Arm Support.
The goal of this study is to minimize arm forces applied during sit-to-stand (STS) transfers in persons with spinal cord injury (SCI) by using functional electrical stimulation (FES) applied to lower limbs muscles. ⋯ Lowest arm forces values were obtained for STS motions that were similar to those of healthy persons in terms of trunk movements and beginning of lower limb movements in regards to maximal trunk acceleration signal. The FES system was able to mimic the rising motion of a healthy individual by triggering the FES at the appropriate moment. This method could prove useful for pivot transfer, therapeutic or functional verticalization.

Pain is one of the common symptoms in patients with Parkinson's disease (PD), with a prevalence of approximately 40-85%. These symptoms affect the quality of life of PD patients. We evaluated the effect of spinal cord stimulation (SCS) to chronic pain and motor symptoms of PD. ⋯ Our results indicate that SCS may be a treatment option for both motor symptoms and chronic pain in PD, especially in cases complicated with lumbar canal stenosis or disc herniation. Further studies are needed to evaluate the efficacy of SCS in PD patients.
