Abstract
Spinal cord stimulation (SCS) has evolved with burst waveform stimulation, addressing limitations of traditional tonic SCS. While tonic SCS uses continuous paresthesia-inducing pulses to mask pain, its long-term efficacy declines and movement-related inconsistencies persist. Burst stimulation mimics natural neural burst firing, engaging medial, lateral and descending inhibitory networks without paresthesia. Clinical evidence demonstrates burst's superiority: randomized trials show significant pain and emotional distress reduction versus tonic SCS, sustained long-term benefits, and patient preference for paresthesia-free therapy. Real-world data confirm durable pain relief and improved quality of life, with burst therapy effective as rescue therapy for tonic nonresponders. Meta-analyses underscore its statistical advantages in pain and functional outcomes. Burst employs lower amplitudes and intermittent cycles, maintaining efficacy while enhancing comfort and device longevity. This efficient approach reduces energy use, prolongs battery life, and mitigates tolerance. By holistically modulating pain's sensory, emotional, and cognitive dimensions, burst stimulation transcends traditional SCS limitations, offering a paradigm shift in managing refractory chronic pain.
