Carpal tunnel syndrome (CTS) is the most common of the compression neuropathies. Several studies have demonstrated the efficacy of wrist splinting in relieving the symptoms of CTS; however, the chosen angle of immobilization has varied. Wick catheter measurements of carpal tunnel pressures suggest that the neural position has less pressure and, therefore, greater potential to provide relief from symptoms. This study is a prospectively gathered, blind trial comparing the symptom relief experienced by wearers of splints immobilized at 20 degrees extension and at neutral. The results indicate that the neutral angle provided superior symptom relief, and that the relief did not often improve between 2 weeks and 2 months of wear. Relief of symptoms was not related to the length of time that the patient had experienced of CTS symptoms. The results also indicate that the results of the electromyography/nerve conduction study (EMG/NCS) do not provide information about the subjects' likely response to splinting.
腕管综合征（CTS）是最常见的压迫性神经病变。多项研究已证实手腕夹板固定在缓解腕管综合征症状方面的有效性；然而，所选择的固定角度各不相同。通过 Wick 导管测量腕管压力表明，神经所处位置压力较小，因此更有潜力缓解症状。本研究是一项前瞻性收集的双盲试验，比较了固定在伸展 20 度和中立位的夹板佩戴者所体验到的症状缓解情况。结果表明，中立位能提供更优的症状缓解效果，且在佩戴 2 周和 2 个月之间，症状缓解效果通常没有改善。症状缓解与患者经历腕管综合征症状的时长无关。结果还表明，肌电图/神经传导研究（EMG/NCS）的结果无法提供有关受试者对夹板固定可能反应的信息。
