以前的研究提供了证据多裂肌萎缩的人腰痛（LBP）。在急性LBP的情况下，这些研究表明，萎缩的模式是脊椎水平和侧面特异性。对于慢性LBP，关于肌肉萎缩的程度和位置有相互矛盾的报道。本研究的目的是比较慢性LBP患者和无症状受试者的多裂肌尺寸（横截面积; CSA）和对称性（相对较大侧与较小侧的比例差异）。数据来自40名无LBP既往史的无症状受试者（13名女性，27名男性），并对50名慢性腰痛患者（27名女性，23名男性）的记录进行回顾性审计。分析结果显示，慢性LBP患者在最低两个椎体节段的多裂肌CSA明显小于无症状受试者。男性在所有椎体节段的多裂肌CSA均显著大于女性，但L5除外，L5是手动检查确定的最常见症状节段。在单侧疼痛表现的患者中，在L5椎体水平观察到两侧之间最大的不对称性。在所有病例中，较小的多裂肌CSA均位于报告疼痛侧的同侧。这项研究的结果支持了以前的研究结果，即慢性LBP患者的多裂肌萎缩模式是局部的，而不是普遍的。此外，在单侧疼痛分布的慢性LBP患者中可以看到两侧之间的不对称性。(c)2006爱思唯尔有限公司保留所有权利。
Previous studies have provided evidence of multifidus muscle atrophy in people with low back pain (LBP). In cases of acute LBP, these studies have shown that the pattern of atrophy is both vertebral level and side specific. For chronic LBP, there are conflicting reports about the extent and location of muscle atrophy. The purpose of this study was to compare chronic LBP patients and asymptomatic subjects on measures of multifidus size (cross-sectional area; CSA) and symmetry (proportional difference of relatively larger side to smaller side). Data were obtained from 40 asymptomatic subjects without a prior history of LBP (13 females, 27 males), and a retrospective audit was undertaken of records from 50 chronic low back pain patients (27 females, 23 males) presenting to a back pain clinic. Results of the analysis showed that chronic LBP patients had significantly smaller multifidus CSAs than asymptomatic subjects at the lowest two vertebral levels. Males were found to have significantly larger multifidus CSAs than females at all vertebral levels except L5, the most common symptomatic level as determined by manual examination. The greatest asymmetry between sides was seen at the L5 vertebral level in patients with unilateral pain presentations. The smaller multifidus CSA was ipsilateral to the reported side of pain in all cases. The results of this study support previous findings that the pattern of multifidus muscle atrophy in chronic LBP patients is localized rather than generalized. Furthermore, between side asymmetry may be seen in chronic LBP patients presenting with a unilateral pain distribution. (c) 2006 Elsevier Ltd. All rights reserved.
