本研究应用磁共振成像（MRI）对腕管综合征患者的鱼际肌进行了评价，并探讨了鱼际肌变化与临床表现和电诊断结果之间的相关性。受试者为临床诊断为腕管综合征的13例患者（17个手腕）。在所有患者中，除了使用Kapandji评分系统、视觉模拟量表（VAS）、手臂、肩部和手部快速残疾（Q-DASH）评分、正中神经电诊断结果和鱼际肌肉MRI进行评估外，还获得病史并进行体格检查。鱼际肌体积与临床数据或电诊断结果无显著相关性。大鱼际肌长轴与握力（P<0.05）和Kapandji评分（P<0.05）显著相关，小鱼际肌短轴与拇短展肌远端运动潜伏期（APB DML）显著相关（P<0.01）。鱼际肌短轴/鱼际肌长轴比值与APB DML和Kanatani分期显著相关。值得注意的是，鱼际肌薄与电诊断变化的严重程度显着相关，而抓力和Kapandji评分与鱼际肌厚度相关。此外，它表明，鱼际肌薄与电诊断变化的严重程度显着相关;此外，鱼际肌长轴和把握功率或Kapandji评分之间有显着的相关性。综上所述，这些结果表明鱼际肌萎缩不影响基于患者的评估，包括VAS和Q-DASH，但反映了电诊断结果，特别是DML和严重程度。本研究的结果表明，鱼际肌萎缩可以用来估计腕管综合征的严重程度。
In the present study, the thenar muscles were evaluated using magnetic resonance imaging (MRI), in addition, the correlations between thenar muscle changes, clinical findings and electrodiagnostic results from patients with carpal tunnel syndrome were investigated. The subjects were 13 patients (17 wrists) who were clinically diagnosed with carpal tunnel syndrome. In all patients, a medical history was obtained and physical examination was performed, in addition to assessment using the Kapandji scoring system, visual analogue scale (VAS), quick-disabilities of the arm, shoulder and hand (Q-DASH) score, electrodiagnostic results of the median nerve, and MRI of the thenar muscles. Thenar muscle volume was not significantly correlated with clinical data or the electrodiagnostic results. The thenar muscle major axis was significantly correlated with grasp power (P<0.05) and the Kapandji score (P<0.05), while the thenar muscle minor axis was significantly correlated with abductor pollicis brevis distal motor latency (APB DML) (P<0.01). In addition, the thenar muscle minor axis/thenar muscle major axis ratio was significantly correlated with APB DML and Kanatani's stage. Notably, thenar muscle thinness was significantly correlated with the severity of electrodiagnostic changes, while the grasp power and Kapandji score were correlated with thenar muscle thickness. Furthermore, it was demonstrated that thenar muscle thinness was significantly correlated with the severity of electrodiagnostic changes; in addition, there was a significant correlation between the thenar muscle major axis and the grasp power or Kapandji score. Taken together, these results revealed that thenar muscle atrophy did not affect patient-based assessments, including VAS and Q-DASH, but reflected electrodiagnostic results, particularly DML and severity. The results of the present study suggest that thenar muscle atrophy can be used to estimate the severity of carpal tunnel syndrome.
