项目摘要

DESCRIPTION (provided by applicant): Carpal tunnel syndrome (CTS) is the most common compression neuropathy and has an immense impact on national health care, worker productivity, and quality of life. Despite its high prevalence and public health cost, our understanding of CTS is limited, and the management of CTS awaits improvement. Currently, CTS is routinely treated by carpal tunnel release surgery, which unfortunately has a number of complications. The concept of this surgical procedure has existed for nearly a century without fundamental challenges. Attempts have been made to conservatively treat CTS using manual therapies, but their effectiveness is ambiguous due to the lack of scientific and clinical evidence In our pursuit of CTS management, we have serendipitously discovered a novel mechanism of carpal tunnel manipulation to obtain tunnel enlargement by narrowing the carpal arch width. This discovery has exciting potential for the development of conservative treatment strategies for CTS. Our approach to carpal tunnel manipulation is in sharp contrast to the existing controversial techniques that try to stretch the carpal arch outwards. Therefore, our ultimate goal is to develop a biomechanical treatment for CTS through rigorous scientific studies on the mechanics and pathomechanics of the carpal tunnel. Our central notion is that CTS can be treated by non-surgical, biomechanical manipulation of the carpal tunnel through the narrowing of the carpal arch width. We hypothesize that strategically applied compression on the wrist can increase carpal tunnel cross-sectional area and decrease carpal tunnel pressure, thus relieving the median nerve from mechanical insult. We will test this hypothesis by systematically investigating the biomechanical relationships among transverse compressive force, carpal tunnel pressure, carpal arch width, and carpal tunnel cross-sectional area using cadaveric specimens and human subjects. The implementation of this project will yield novel knowledge on carpal tunnel mechanics and pathomechanics, leading to an evidence-based, novel biomechanical treatment strategy for CTS.

描述（由申请人提供）：腕管综合征（CTS）是最常见的压缩神经病，对国家卫生保健，工人的生产力和生活质量产生了巨大影响。尽管患病率很高和公共卫生成本，但我们对CTS的理解是有限的，并且对CTS的管理正在等待改进。目前，CTS通常通过腕管释放手术对其进行治疗，不幸的是，这有很多并发症。该手术程序的概念已经存在了近一个世纪，而没有根本的挑战。已经尝试使用手动疗法进行保守治疗CTS，但是由于我们追求CTS管理时缺乏科学和临床证据，它们的有效性是模棱两可的，我们偶然发现了一种新颖的腕管操纵机制，可以通过腕弓宽范围来缩小隧道的扩大。这一发现具有令人兴奋的潜力，可以制定CTS的保守治疗策略。我们进行腕管操作的方法与试图将腕弓向外伸展的现有有争议的技术形成鲜明对比。因此，我们的最终目标是通过对腕管的力学和病理学的严格科学研究来开发CTS的生物力学治疗。我们的中心概念是，可以通过腕骨宽度的狭窄腕管对腕管对腕管的非手术生物力学操纵来处理CT。我们假设在手腕上进行策略性地施加压缩可以增加腕管横截面区域并降低腕管压力，从而减轻中位神经免于机械损伤。我们将使用尸体标本和人类受试者系统地研究横向压缩力，腕管压力，腕弓宽度和腕管横截面区域之间的生物力学关系来检验这一假设。该项目的实施将产生有关腕管机械和病理学的新知识，从而导致CTS基于证据的新型生物力学治疗策略。
