UNLABELLED Spinal dorsal column stimulation (DCS) modulates sensory transmission, including pain, at the dorsal horn of the cord. However, the mechanisms of DCS modulatory actions and the effects of anesthetics on these mechanisms remain to be investigated. We studied the effects of isoflurane (1.0% and 2.0%) on conditioned inhibition, the amplitude decrease of the spinal cord potentials (SCPs)...
In individuals with motor-complete spinal cord injury, epidural stimulation of the lumbosacral spinal cord at 2 Hz evokes unmodulated reflexes in the lower limbs, while stimulation at 22-60 Hz can generate rhythmic burstlike activity. Here we elaborated on an output pattern emerging at transitional stimulation frequencies with consecutively elicited reflexes alternating between large and small....
Recent studies have shown that the specific application of transcranial direct current stimulation (tDCS) over the cerebellum can modulate cerebellar activity. In parallel, transcutaneous spinal DC stimulation (tsDCS) was found to be able to modulate conduction along the spinal cord and spinal cord functions. Of particular interest is the possible use of these techniques in pediatric age, since...
This study tested the idea that there are sets on neurons in the spinal cord responsible for generating elementary synergies (movement primitives) that could have implications for FES. Intraspinal, intramuscular, epineural and spinal root stimulation were compared in the anesthetized cat. Ventral root stimulation produced downward and backward movements of the leg while dorsal root stimulation ...
BACKGROUND Repeated periods of stimulation of the spinal cord and training increased the ability to control movement in animal models of spinal cord injury. We hypothesised that tonic epidural spinal cord stimulation can modulate spinal circuitry in human beings into a physiological state that enables sensory input from standing and stepping movements to serve as a source of neural control to u...
We investigated whether the 2 Hz electroacupuncture (EA) analgesia is associated with phosphorylation of N-methyl-D-aspartate receptor (NMDAR) NR-1 subunits and NMDAR antagonism in the lumbar spinal cord of rats. EA stimulation produced an increase of serine phosphorylation of NMDAR NR-1 subunits in the spinal cord as compared with normal conditions. However, the intrathecal injection of NMDAR ...
Spinal cord stimulation (SCS) is minimally invasive and reversible therapy for treatment of severe, otherwise nonresponsive chronic pain. Such approach is relatively safe, with very few side-effects, not addictive, and provides enduring therapeutic response. A number of clinical studies support the efficacy of spinal cord stimulation in treating failed back surgery syndrome and complex regional...
Since its introduction as a procedure of last resort in a terminally ill patient with intractable cancer-related pain, spinal cord stimulation has been used to effectively treat chronic pain of varied origins. Spinal cord stimulation is commonly used for control of pain secondary to failed back surgery syndrome and complex regional pain syndrome, as well as pain from angina pectoris, peripheral...
Cervical somatosensory evoked potentials, brainstem evoked potentials, visual evoked potentials, and the cerebral contingent negative variation were recorded in patients with definite multiple sclerosis before, during, and after spinal cord stimulation. Improvements were seen in the cervical somatosensory and brainstem evoked potentials but neither the visual evoked potential nor the contingent...
Background: Stimulation of the spinal cord has been shown to have great potential for improving function after motor deficits caused by injury or pathological conditions. Using a wide range of animal models, many studies have shown that stimulation applied to the neural networks intrinsic to the spinal cord can result in a dramatic improvement of motor ability, even allowing an animal to step a...
