Fig. 3From: Tonic and burst spinal cord stimulation waveforms for the treatment of chronic, intractable pain: study protocol for a randomized controlled trialWaveforms. Tonic stimulation provides a consistent stream of pulses at a set frequency, pulse width, and amplitude. Burst stimulation delivers groups of pulses at a lower amplitude and a higher frequency than tonic stimulation. Bursts of pulses are followed by pulse-free periods during which charge balance occursBack to article page
