INTRODUCTION • Carpal tunnel syndrome (CTS) is associated with elevated carpal tunnel pressure. • An unobtrusive and non-invasive device was developed to non-surgically treat CTS by relieving pressure on the median nerve. • This carpal tunnel manipulation device (CTMD) attaches to the volar wrist and applies negative pressure by lifting the underlying tissue. • In a pilot study, 4 weeks of daily CTMD use significant improved CTS symptoms with improvement seen as early as 2 weeks [1]. • The effect the device has on pressure within the wrist is unknown. PURPOSE & HYPOTHESES Purpose: • To investigate changes of pressure within the wrist in response to wrist manipulation applied by volarly lifting the tissues Hypothesis: • Pressure would decrease with the application of wrist tissue manipulation METHODS • Eight (n=8) cadaveric specimens • The specimen was fixed in an anatomically neutral position within a splint attached to a wooden base. • CTMD was modified to fit curvature of wrist to standardize pull length. Placed 1 cm proximal to DWC. • Pressure within wrist measured by DigiTact tactile pressure transducer inserted under the MN (Fig. 1). • The wrist regions under investigation include the carpal tunnel (distal wrist), beneath the CTMD (proximal wrist), and the region between the two (middle wrist) (Fig. 1). • PTA Balloon Dilation Catheter (AT-120184, Atlas, Tempe, AZ) inserted to standardize baseline pressure beneath the CTMD (Fig. 1). • Denso Robot pulled CTMD up to 6mm in 1 mm increments, pausing for 5 sec at each level. • Pressure was recorded simultaneously at 50 Hz. • The procedure was repeated for 20 trial介绍 •腕管综合征(CTS)与 腕管压力升高。 •设计了一种不引人注目的非侵入性设备 发展到非手术治疗CTS的缓解 正中神经受压。 •此腕管操纵装置(CTMD) 附着到掌侧腕关节并应用负片 通过提起下面的组织施加压力。 •在一项初步研究中,每天使用CTMD 4周 显著改善CTS症状 最早可在2周内看到改善[1]。 •装置对管道内压力的影响 手腕是未知的。 目的与假设 目的: •调查手腕内的压力变化 针对volarly采用的手腕手法 提起纸巾 假设: •压力会随着压力的应用而降低 腕组织手法 方法 •八(n=8)具尸体标本 •将样本固定在解剖中立的位置 放置在连接到木制底座的夹板内。 •对CTMD进行了修改,以适应手腕的弯曲度 标准化拉力长度。放在离地面近1厘米处 DWC。 •通过Digitat触觉测量手腕内的压力 插入MN下方的压力传感器(图。 1). •正在调查的腕部区域包括: 腕管(腕远端),位于CTMD下方 (近端腕部),以及两者之间的区域 (手腕中部)(图1)。 •PTA球囊扩张导管(AT-120184,Atlas, Tempe,AZ)插入以标准化基线 CTMD下方的压力(图1)。 •Denso机器人在1毫米内将CTMD拉至6毫米 递增,每级暂停5秒。 •在50 Hz下同时记录压力。 •重复该程序进行20次试验
