Abstract

Introduction and aims: The objective of treatment of complex regional pain syndrome is to relieve pain and restore function in the affected limb. The aim of this study is to evaluate spinal cord stimulation as a therapy for patients diagnosed with complex regional pain syndrome, for whom adequate pain control could not be achieved with other previous treatments.

Patients and methods: A prospective study was conducted from 2018 to 2020. We included patients diagnosed with complex regional pain syndrome refractory to other treatments or techniques, classified by demographic data. Efficacy, functionality and opioid dependence in each patient were subsequently monitored for one year.

Results: Seven of the 13 patients (53.84%) included in the study achieved significant pain relief with spinal cord stimulation. Improvements in pain and functionality were obtained, and both were statistically significant (p < 0.001 and p = 0.003, respectively). Improvement in the Oswestry Disability Index/Neck Disability Index (ODI/NDI) was significantly associated with body mass index (BMI) (p = 0.011) and was lower as BMI increased.

Conclusions: The results suggest that spinal cord stimulation is an effective therapeutic option for patients with CRPS refractory to other treatments. BMI and ODI/NDI also showed a significant correlation.

[脊髓刺激治疗难治性复杂区域疼痛综合征。前瞻性研究]。

导言和目的：治疗复杂性区域疼痛综合征的目的是缓解疼痛并恢复患肢的功能。本研究的目的是评估脊髓刺激作为一种疗法对确诊为复杂性区域疼痛综合征患者的治疗效果，对于这些患者，之前的其他治疗方法无法实现充分的疼痛控制：从 2018 年至 2020 年开展了一项前瞻性研究。我们纳入了被诊断为其他治疗方法或技术难治的复杂区域疼痛综合征患者，并根据人口统计学数据进行了分类。随后对每位患者的疗效、功能和阿片类药物依赖性进行了为期一年的监测：结果：在参与研究的 13 名患者中，有 7 人（53.84%）通过脊髓刺激治疗后疼痛明显缓解。疼痛和功能均有改善，且均有统计学意义（p < 0.001 和 p = 0.003）。奥斯韦特里残疾指数/颈部残疾指数（ODI/NDI）的改善与体重指数（BMI）显著相关（p = 0.011），并且随着体重指数的增加而降低：结论：研究结果表明，脊髓刺激对于其他疗法难治的 CRPS 患者是一种有效的治疗选择。BMI和ODI/NDI也显示出显著的相关性。
