Meralgia paresthetica (MP), a common entrapment syndrome, presents with paresthesias in the anterolateral aspect of the thigh. Clinical tests used to diagnose MP are the pelvic compression test, neurodynamic testing, and Tinel's sign. The diagnostic accuracy of these three tests has not been analyzed to date. Hence, this study aims to analyze the sensitivity and specificity of these clinical tests. This study was a hospital-based case-control study that included 30 electrophysiologically proven patients with MP. The data were gathered over a period of 6 months after obtaining institutional ethics committee clearance. Demographics and risk factors among our cases are in keeping with the global scenario. The sensitivity and specificity of the pelvic compression test were 86.7% and 93.0%, the Tinsel sign was 85.1% and 87.5%, and neurodynamic testing was 86.7% and 93.0%, respectively. Our study proves that these tests are a simple and accurate aid in the diagnosis of MP. These bedside clinical tests can be utilized to establish a diagnosis of MP in a setting of conflicting differentials such as lumbar canal stenosis or thoracolumbar junction disc pathologies and guide in choosing the next line of investigation.
股外侧皮神经卡压综合征（MP）是一种常见的卡压综合征，表现为大腿前外侧感觉异常。用于诊断MP的临床检查包括骨盆挤压试验、神经动力试验和Tinel征。迄今为止，尚未对这三项检查的诊断准确性进行分析。因此，本研究旨在分析这些临床检查的敏感性和特异性。本研究是一项基于医院的病例对照研究，纳入了30例经电生理证实的MP患者。在获得机构伦理委员会批准后，在6个月的时间内收集数据。我们病例中的人口统计学和危险因素与全球情况一致。骨盆挤压试验的敏感性和特异性分别为86.7%和93.0%，Tinel征分别为85.1%和87.5%，神经动力试验分别为86.7%和93.0%。我们的研究证明，这些检查是诊断MP的简单而准确的辅助手段。这些床边临床检查可用于在腰椎管狭窄或胸腰段椎间盘病变等鉴别诊断存在冲突的情况下确立MP的诊断，并指导选择下一步的检查。
