![]() ![]() Thus, the dose of stimulation can automatically be kept at optimum therapeutic levels despite 1) the movement of the spinal cord in relation to the electrodes or 2) other physiologic changes in the patient’s body and the stimulation system, such as increased electrode impedance with scarring. (A generator that allows rapid sequential delivery of pulses to different contacts is not, strictly speaking, a multichannel device instead it is a “gated single channel” generator.)ĬLOSED LOOP STIMULATION – a type of stimulation that adjusts automatically (typically in amplitude) in response to one or more inputs, such as the amplitude of evoked compound action potentials (usually recorded from the spinal cord via electrode contacts that are not in use for stimulation). Compared with an anode, a cathode initiates action potential generation (depolarization) at a lower amplitude threshold thus, cathodal effects predominate.ĬHANNEL – multiple independent channels allow simultaneous delivery of pulses of different amplitudes to different contacts. Practice Parameters for the Use of Spinal Cord Stimulation in the Treatment of Chronic Neuropathic Pain Glossary & AcronymsĪCTION POTENTIAL – a rapid rise and fall in voltage and chemical gradients across a neuronal membrane, which can propagate over distance (most rapidly along a myelinated axon) and can be triggered or inhibited by electrical stimulation.ANODE - a stimulating contact programmed as a positive pole, which attracts negative ions.ĪNODE – a stimulating contact programmed as a positive pole, which attracts negative ions.ĬATHODE – a stimulating contact programmed as a negative pole, which attracts positive ions.
