Spinal cord stimulation (SCS) has been used to treat sustained pain that is intractable despite various types of treatment. However, conventional tonic waveform SCS has not shown promising outcomes for spinal cord injury (SCI) or postamputation pain. The pain signal mechanisms of burst waveforms are different to those of conventional tonic waveforms, but few reports have presented the therapeutic potential of burst waveforms for the abovementioned indications. This current case report describes two patients with refractory upper limb pain after SCI and upper limb amputation that were treated with burst waveform SCS. While the patients could not obtain sufficient therapeutic effect with conventional tonic waveforms, the burst waveforms provided better pain reduction with less discomfort. However, further studies are necessary to better clarify the mechanisms and efficacy of burst waveform SCS in patients with intractable pain.
脊髓刺激（SCS）已被用于治疗尽管经过各种类型的治疗但仍难以治愈的持续性疼痛。然而，传统的强直波形SCS在脊髓损伤（SCI）或截肢后疼痛方面并未显示出有前景的结果。爆发波形的疼痛信号机制与传统的强直波形不同，但很少有报告阐述爆发波形在上述适应症中的治疗潜力。本病例报告描述了两名SCI和上肢截肢后难治性上肢疼痛的患者，他们接受了爆发波形SCS治疗。虽然患者使用传统的强直波形无法获得足够的治疗效果，但爆发波形在减轻疼痛的同时减少了不适感。然而，需要进一步研究以更好地阐明爆发波形SCS在难治性疼痛患者中的机制和疗效。
