腰椎棘突 (SP) 的准确触诊是脊柱评估的关键组成部分。使用基于外部皮肤标记的测量系统时，这对于准确测量脊柱运动也至关重要，该系统越来越多地用于了解腰部疾病及其治疗。目的是使用位置磁共振成像 (MRI) (pMRI) 评估腰椎棘突 (SP) 触诊的准确性。两位经验丰富的手法治疗师对 9 名无痛参与者在站立和俯卧时的 L4 SP 进行触诊。对于每个位置，将 MRI 标记附着在 SP 上并进行 pMRI 扫描。目视检查 MRI 图像上与 L4 相关的标记位置，并使用从标记的上/下方面到 L4 SP 的上/下方面的垂直距离的测量值 (mm) 来确定触诊准确性。71% 的标记正确放置在 L4 SP 上。错误放置标记的误差幅度很小，其中一位治疗师俯卧触诊时记录的最大中位距离为 2.7 毫米（四分位距 (IQR) 0-3.6）。 100% 的标记正确放置在 L4 上或高度上的一个 SP 内。pMRI 可用于调查与临床和研究实践相关的位置的 SP 触诊的准确性。 (c) 2012 Elsevier Ltd. 保留所有权利。
Accurate palpation of lumbar spinous processes (SPs) is a key component of spinal assessment. It is also vital for the accurate measurement of spinal motion when using external skin marker-based measurement systems, which are being increasingly used to understand low back disorders and their management.The aim was to assess the accuracy of lumbar spinous process (SP) palpation using positional magnetic resonance imagery (MRI) (pMRI).Two experienced manual therapists palpated the L4 SP of nine pain-free participants in standing and prone lying. For each position, an MRI marker was attached over the SP and pMRI scanning was conducted. The position of the marker in relation to L4 on the MRI images was visually inspected, and measurements (mm) of the vertical distance from the superior/inferior aspect of the marker to the superior/inferior aspect of the L4 SP were used to determine palpation accuracy.71% of Markers were correctly placed over the L4 SP. The magnitude of error for incorrectly placed markers was small, with the largest median distance of 2.7 mm (interquartile range (IQR) 0-3.6) recorded for one of the therapists palpating in prone lying. 100% of markers were correctly placed either on L4 or within one SP in height.pMRI is useful for investigating the accuracy of SP palpation in positions relevant to clinical and research practice.
